About the Role:
We are seeking a technically strong, hands-on Senior Database Reliability Engineer to help design, build, and scale the database platform used across Sezzle’s applications.
This is not a traditional DBA role. This role is for an engineer who can combine deep database knowledge with software engineering, infrastructure engineering, and platform thinking. You will help build the systems, libraries, automation, standards, and guardrails that make database usage across Sezzle reliable, secure, scalable, and easy for developers to adopt correctly.
As a Senior Database Reliability Engineer, you will be responsible for improving how Sezzle applications connect to, migrate, operate, observe, and scale their databases. You will work across application teams, infrastructure, security, and engineering leadership to define patterns that improve database reliability by design — not just by operational response.
You should be comfortable owning problems end-to-end: understanding application behavior, reading code, reviewing database access patterns, building shared tooling, improving connection management, designing migration safety checks, analyzing production performance, and helping developers use databases in safer and more scalable ways.
You should consider yourself a DOer to be a good fit for this role. We are looking for someone who can ship production-quality engineering work, not just advise from the sidelines. With AI tooling and automation, you should be a force multiplier for database reliability, developer productivity, and operational excellence across Sezzle.
Compensation:
For this senior development role, with 6+ years of experience, the compensation range is $5,000 - $9,500 USD per month. This range acknowledges the extensive expertise, leadership capabilities, and significant contributions expected at this level, offering a competitive salary to reflect the value of advanced skills and experience.
What You'll Do:
- Design, build, and maintain shared database platform components used by Sezzle applications, such as database connection packages, database client libraries, migration tooling, safety checks, query standards, and developer-facing abstractions.
- Establish reliable, scalable patterns for how Sezzle services connect to and interact with relational databases across production, staging, and development environments.
- Partner with backend engineering teams to improve database usage in application code, including connection lifecycle, transaction handling, retries, timeouts, pooling, query patterns, and migration workflows.
- Build automation and internal tooling that makes database operations safer, more repeatable, and less dependent on manual intervention.
- Define and enforce engineering standards for database access, schema design, migrations, indexing, query performance, connection management, and operational readiness.
- Architect and improve database infrastructure across AWS RDS/Aurora MySQL, PostgreSQL, RDS Proxy, read replicas, backups, failover, parameter groups, monitoring, and capacity planning.
- Lead database reliability initiatives that reduce operational risk, improve performance, and help Sezzle scale safely.
- Review application designs and database changes early in the development lifecycle to ensure reliability, scalability, maintainability, and security are built in from the start.
- Build guardrails for database migrations, including automated checks, rollback expectations, schema review workflows, migration observability, and production safety controls.
- Improve developer self-service for database provisioning, access, schema management, local development, testing, and observability.
- Investigate production database issues by combining application telemetry, database metrics, logs, query plans, traces, and cloud infrastructure data.
- Identify and fix systemic database problems, not just symptoms — including bad access patterns, unsafe migrations, inefficient queries, connection storms, lock contention, replication lag, and capacity bottlenecks.
- Create and maintain high-signal dashboards, alerts, SLOs, SLIs, runbooks, and operational readiness checks for database-backed services.
- Drive improvements in database backup validation, restore testing, disaster recovery, failover readiness, and business continuity.
- Work with security and compliance teams to improve database access controls, auditability, encryption, secrets management, least privilege, and PCI/SOC 2 aligned controls.
- Mentor engineers on database design, query performance, safe migrations, operational readiness, and production debugging.
- Use automation and AI tooling where appropriate to improve migration review, query analysis, incident investigation, documentation, and developer productivity.
What We Look For:
- 6+ years of professional software engineering, infrastructure engineering, database engineering, SRE, or platform engineering experience.
- Strong software engineering ability in at least one production programming language such as Go, Python, or TypeScript.
- Proven ability to build production-quality internal tools, libraries, frameworks, services, or platform components used by other engineers.
- Deep hands-on experience with relational databases, especially MySQL and/or PostgreSQL, in high-availability production environments.
- Strong understanding of how application code interacts with databases, including connection pooling, transactions, isolation levels, retries, timeouts, deadlocks, locking, migrations, and query execution.
- Experience designing or improving shared database access patterns, internal database packages, ORM wrappers, migration frameworks, or developer-facing database tooling.
- Hands-on experience with AWS RDS/Aurora, including provisioning, upgrades, replicas, backups, failover, monitoring, parameter tuning, and production troubleshooting.
- Experience with database connection management technologies such as RDS Proxy, PgBouncer, ProxySQL, or application-level pooling.
- Strong ability to analyze database performance using query plans, indexes, slow query logs, wait events, locks, metrics, and application traces.
- Experience designing safe database migration processes for production systems.
- Strong understanding of observability for database-backed applications, including metrics, logs, traces, SLOs, alerting, and incident response.
- Experience with infrastructure-as-code and CI/CD systems such as Terraform, GitLab CI/CD, Kubernetes, Helm, or similar tooling.
- Ability to influence engineering teams through clear design reviews, documentation, technical standards, and practical implementation.
- Ability to operate independently, identify high-impact problems, propose pragmatic solutions, and drive them to completion.
- Demonstrated experience working with Claude or equivalent large language model tools is required; candidates must be comfortable leveraging AI to enhance productivity, research, and communication.
- Bachelor’s degree in Computer Science.
Preferred Knowledge and Skills:
- Experience building platform capabilities for a microservices environment.
- Experience with Golang application development and database access patterns.
- Experience creating database libraries, SDKs, service templates, migration frameworks, or paved-road developer tooling.
- Experience improving database reliability across many services or teams, not just one application.
- Experience with fintech, payments, banking, e-commerce, or other high-volume transactional systems.
- Experience with compliance-sensitive environments such as PCI DSS, SOC 2, or SOX.
- Experience with database access governance, audit logging, secrets management, encryption, IAM authentication, and least-privilege access models.
- Experience with large-scale operational automation for provisioning, patching, failover testing, backup validation, access management, or schema review.
- Experience with distributed systems patterns such as transactional outbox, event-driven architecture, idempotency, queues, eventual consistency, and data consistency tradeoffs.
- Experience with observability tools such as Prometheus, Grafana, Datadog, CloudWatch, Performance Insights, OpenTelemetry, or New Relic.
- Familiarity with Elasticsearch or other supporting data stores.
- Familiarity with AI developer tooling such as Claude Code, Gemini CLI, Codex, Cursor, and using it to be a more productive engineer.
About You:
- You have relentlessly high standards - many people may think your standards are unreasonably high. You are continually raising the bar and driving those around you to deliver great results. You make sure that defects do not get sent down the line and that problems are fixed so they stay fixed.
- You’re not bound by convention - your success—and much of the fun—lies in developing new ways to do things.
- You need action - speed matters in business. Many decisions and actions are reversible and do not need extensive study. We value calculated risk-taking.
- You earn trust - you listen attentively, speak candidly, and treat others respectfully.
- You have backbone; disagree, then commit - you can respectfully challenge decisions when you disagree, even when doing so is uncomfortable or exhausting. You have conviction and are tenacious. You do not compromise for the sake of social cohesion. Once a decision is determined, you commit wholly.
- You deliver results - you focus on the key inputs and deliver them with the right quality and in a timely fashion. Despite setbacks, you rise to the occasion and never settle.

Tips for Your Senior Database Reliability Engineer Job Search
Quantify reliability wins on your resume
Recruiters for senior database reliability engineer roles want numbers. Replace vague statements with metrics: replication lag reduced, query latency cut, recovery time objectives met. A resume that shows concrete SLO and SLA outcomes moves faster through technical screening than one listing tools alone.
Highlight your incident postmortem contributions
Senior roles demand ownership of failures, not just fixes. On your resume and in interviews, reference specific postmortems you authored or led. Hiring managers for database reliability positions treat blameless postmortem culture as a signal of engineering maturity, so make yours visible.
Apply early to roles that fit
Migrate Mate lists senior database reliability engineer openings from across the United States in one place, so you can find roles that match and apply directly to each listing.
Filter openings by your primary database engine
Senior database reliability engineer postings differ sharply by stack. A role built around Aurora PostgreSQL requires a different conversation than one centered on Cassandra or CockroachDB. Targeting openings that match your deepest engine experience shortens your interview cycle and strengthens your negotiating position.
Prepare a live troubleshooting walkthrough
Technical interviews for senior database reliability engineers routinely include a live debugging or query-tuning exercise. Practice narrating your diagnostic process out loud, including how you read execution plans, check replication health, or isolate lock contention, before you sit in the actual interview.
Negotiate scope before negotiating compensation
Before discussing pay, clarify whether the role owns on-call rotations solo or shares them, and whether you have authority to enforce schema change processes. Database reliability scope varies widely across companies, and a narrower mandate is often a signal to push for higher base compensation.
Senior Database Reliability Engineer Jobs: Frequently Asked Questions
Which companies are hiring the most senior database reliability engineers?
The companies hiring the most senior database reliability engineers right now include Okta, Airwallex, and PointClickCare, with the largest share of openings in New York, California, and Florida, based on current listings on Migrate Mate as of June 2026. Demand is especially concentrated in companies running high-transaction cloud infrastructure.
How many senior database reliability engineer jobs are remote?
About 50% of senior database reliability engineer openings are fully remote or hybrid as of June 2026, reflecting strong demand for async-capable engineers. Roles focused on cloud-native databases and observability tooling tend to be the most remote-friendly, while positions requiring hands-on data center or on-premises storage work are more likely to require on-site presence.
How do you become a senior database reliability engineer?
Start by building a foundation in database administration or backend engineering, then deepen expertise in a specific engine like PostgreSQL or Cassandra. Move into reliability-focused work by owning on-call rotations, writing postmortems, and improving SLOs. Seniority comes from leading cross-team incidents, designing replication architectures, and demonstrating ownership of production database health end to end.
Can you get hired as a senior database reliability engineer with limited experience?
Hiring managers rarely waive the seniority bar outright, but engineers who have led a high-impact reliability project, a major migration, or a significant incident response often move through screening even without a matching job title on their resume. Frame your experience around outcomes: uptime improved, recovery time shortened, or query performance measurably changed.
What does the senior database reliability engineer interview process look like?
Most processes run in three to four stages. A recruiter screen is followed by a technical phone interview covering database internals and past incidents. Then comes a live debugging or architecture design session, often including a real or simulated production scenario. Final rounds typically include a systems design conversation with staff or principal engineers and a cross-functional interview with platform or SRE leadership.
Where can I find and apply to senior database reliability engineer jobs?
You can find and apply to senior database reliability engineer jobs on Migrate Mate, which lists current openings from across the United States. Search the listings to find roles that match your database engine experience and reliability background, then apply directly to each one that fits.
