Who You Are
You'll design and build backend systems powering blockchain infrastructure and staking products across Galaxy — spanning Ethereum-based systems, staking infrastructure (native and liquid), and blockchain data systems and APIs. Liquid Collective is one of several key initiatives you'll contribute to. This is a hands-on role with significant ownership and influence. You'll play a key part in shaping architecture, development practices, and engineering culture — not just building features, but raising the bar on how the team works. You'll own systems end-to-end, from architecture through to observability, and you'll operate in a spec-first development environment that increasingly leverages AI-assisted workflows. Typical time allocation: roughly 60% building systems and features, 20% code review and mentorship, 20% design, architecture, and product collaboration.
What You’ll Do
Build and own backend systems
+ Design and build APIs, services, Ethereum data pipelines and indexers, staking and validator infrastructure integrations, and monitoring and operational tooling.
+ Own system design end-to-end: architecture, implementation, testing, deployment, and observability.
+ Work across the Ethereum stack, integrating with both execution layer and consensus layer clients.
+ Contribute to Liquid Collective alongside other staking and blockchain infrastructure projects across Galaxy.
Define and uphold engineering standards
+ Set and maintain the bar on API design, testing strategies for distributed systems, reliability and fault tolerance, and security and key management practices.
+ Operate in a spec-first development environment — translate product and protocol requirements into clear technical specs before building.
+ Leverage AI-assisted development workflows (e.g. Claude Code) and work with emerging paradigms like MCP (Model Context Protocol) and agent-based tooling.
Collaborate and contribute to engineering culture
+ Work cross-functionally with protocol, product, and infrastructure teams.
+ Mentor engineers through code review, design feedback, and raising the overall quality of what the team ships.
+ Contribute to how the team evolves its practices — not just executing within the current system, but improving it.
Embrace and champion the thoughtful adoption of AI to improve team performance and business outcomes.
* Leverage AI tools (e.g., generative AI, automation platforms, data copilots) to improve productivity, decision-making, and output quality in your day-to-day work.
What We’re Looking For
7+ years of professional software engineering experience.
Strong experience building backend systems in Golang.
Deep understanding of distributed systems. Experience working with blockchain systems, preferably Ethereum — including familiarity with execution vs consensus layers, node operation, and data flow.
Experience with cloud-native infrastructure: AWS, Kubernetes, Helm, GitOps (e.g. Flux).
Strong testing practices for complex and stateful systems.
Experience working in remote, asynchronous teams.
* High agency, low ego — you own your work end-to-end and hold yourself accountable for quality.
Bonus Points
Hands-on experience with Ethereum nodes (execution and/or consensus clients) or validator and staking infrastructure.
Understanding of proof-of-stake mechanisms.
Experience building blockchain indexers, data pipelines, dApps, or smart contracts (Solidity).
Familiarity with AI-assisted development workflows: spec-driven development, code generation tools, MCP, or agent-based paradigms.
Contributions to open-source projects.
Experience with Rust.
What We Offer
Competitive base salary and discretionary bonus
Hybrid/Flexible Working Arrangements
Flexible Time Off (paid)
3% 401(k) company contribution
Company-paid health and protective benefits for employees, partners, and other dependents
Generous paid Parental Leave
Competitive family planning benefits for US employees
Opportunities to learn about the Crypto industry
Smart, entrepreneurial, and fun colleagues
Free daily snacks and weekly breakfasts/lunches
Employee Resource Groups
Free coaching and counseling sessions through Headspace

Tips for Your Senior Backend Developer Job Search
Tailor your resume to system scale
Senior backend roles prioritize demonstrated experience with high-throughput systems. Quantify the scale you've worked at, such as requests per second, data volume, or concurrent users, so hiring managers can immediately gauge whether your background matches their infrastructure needs.
Apply early to roles that fit
Migrate Mate lists senior backend developer openings from across the United States in one place, so you can find roles that match and apply directly to each listing.
Highlight architecture ownership on your resume
Many candidates list technologies without showing decision-making authority. Specify systems or components you designed end-to-end, the tradeoffs you evaluated, and the outcomes. Reviewers at the senior level are looking for engineers who drove technical direction, not just implemented it.
Filter openings by your core stack
Senior backend postings vary sharply by language and framework. Search for openings that name your primary stack, such as Go, Java, or Python with Django, so you avoid screening calls where a stack mismatch disqualifies you before the technical round begins.
Prepare a system design answer in advance
Nearly every senior backend interview includes a live system design question. Practice structuring your answer around requirements gathering, capacity estimation, and component tradeoffs before your first call so you're not improvising the format under pressure.
Negotiate scope before accepting an offer
At the senior level, scope matters as much as compensation. Before accepting, clarify whether you'll own greenfield projects or maintain legacy systems, how on-call is structured, and whether the role has a path toward staff or principal, so the role matches your actual goals.
Senior Backend Developer Jobs: Frequently Asked Questions
Which companies are hiring the most senior backend developers?
The companies hiring the most senior backend developers right now include Citi, Infojini, and Photon, with the largest share of openings in Texas, California, and New York, based on current listings on Migrate Mate as of June 2026. Fintech and enterprise SaaS companies consistently post the highest volume of senior backend roles.
How many senior backend developer jobs are remote?
About 31% of senior backend developer openings are fully remote or hybrid as of June 2026, making it one of the more remote-accessible engineering roles at the senior level. Distributed systems, API platform, and cloud infrastructure positions tend to offer the highest share of remote-friendly arrangements among backend specializations.
How do you become a senior backend developer?
Reaching the senior level typically requires building production systems at meaningful scale, owning components end-to-end rather than implementing tickets, and developing fluency in distributed system tradeoffs. Earning depth in one primary language, contributing to architecture decisions, mentoring more junior engineers, and shipping projects with measurable reliability or performance outcomes all move candidates from mid-level to senior faster than tenure alone.
Can you get hired as a senior backend developer without extensive experience?
A strong portfolio of self-directed or open-source projects that demonstrate system design, performance optimization, and reliability can offset a shorter professional history. Candidates who contribute meaningfully to well-known open-source backends, build side projects that reach real users, or move into senior roles at smaller companies before targeting larger ones have made this transition successfully.
What does the senior backend developer interview process look like?
Most senior backend interview processes include a recruiter screen, a technical phone interview covering data structures and algorithms, one or two system design rounds where you architect a scalable service from scratch, a coding exercise focused on real-world backend problems, and a final round of behavioral or leadership discussions. Some companies also include a take-home or a code review exercise assessing how you evaluate existing systems.
Where can I find and apply to senior backend developer jobs?
You can find and apply to senior backend developer jobs on Migrate Mate, which lists current openings from across the United States. Search the listings to find roles that match your stack and experience level, then apply directly to each one that fits.
