About the Role
Our team is looking for a Senior Full Stack Engineer to help build the future of Customer Agent, Klaviyo's AI-native conversational platform. In this role, you'll play a critical part in shaping how autonomous service, AI-driven support, and agentic commerce experiences evolve at scale across millions of customer interactions.
You'll work across the stack to design, build, and scale systems that power intelligent workflows, conversational experiences, tools integrations, retrieval systems, onboarding flows, observability, and multi-channel customer engagement. You'll help develop both foundational platform capabilities and customer-facing experiences that enable brands to launch, customize, and continuously improve their own highly-configurable AI agents.
As a Senior Engineer, you'll tackle complex technical and product challenges, develop multiple solution paths, and evaluate business and architectural trade-offs to determine the best approach. You'll also act as a technical leader and mentor, driving engineering quality, execution, and decision-making across projects. Additionally, you'll be responsible for deploying well-designed, thoroughly tested solutions that prioritize reliability, scalability, and customer impact.
The Customer Agent team is building one of Klaviyo's most ambitious and strategic product areas: an extensible AI platform that enables brands to deliver personalized, autonomous customer experiences across channels like chat, email, SMS, and beyond. We operate with high ownership, rapid iteration cycles, and a strong bias toward execution. Every engineer is expected to think holistically about customer outcomes, collaborate deeply across engineering, product, design, data science, and go-to-market teams, and push beyond traditional role boundaries to help the team move faster.
Success in this role means shipping high-quality systems quickly, contributing to foundational platform decisions, improving the intelligence and reliability of our agent experiences, and helping define how AI-powered customer engagement evolves at Klaviyo.
What We're Looking For
- A proven track record of building high-quality products and systems, with pride in writing clean, maintainable, high-quality code.
- 7+ years of experience in a software engineering role.
- Strong experience developing end-to-end software solutions or extensive experience across both front-end and back-end technologies.
- Experience building scalable, customer-facing systems in fast-moving product environments - we operate like a startup inside of Klaviyo.
- Experience leading projects and being accountable for technical and business outcomes.
- Experience mentoring team members or driving initiatives that help the team grow and learn new skills.
- Experience conducting code reviews and maintaining a robust testing and deployment cycle.
- Curiosity and enthusiasm for AI-native product development, including practical experience experimenting with LLMs, AI tooling, or agentic workflows in professional or personal projects.
- Excitement about leveraging AI to improve engineering velocity, customer experiences, and operational workflows.
- A strong product mindset and willingness to collaborate cross-functionally to solve ambiguous problems with urgency and pragmatism.
Nice to Have
- Skills with Python and related technologies.
- Skills with React and related technologies.
- Experience building conversational AI systems, workflow engines, or agentic platforms.
- Experience with retrieval systems, embeddings, eval frameworks, or LLM orchestration patterns.
- Experience building cloud-native solutions, ideally with AWS.
- Experience developing customer support, commerce, marketing, or customer data software solutions.
- Experience with machine learning systems or AI infrastructure.
- Experience building multi-tenant or highly configurable SaaS platforms.
- Familiarity with observability, tracing, experimentation, or AI quality/evaluation tooling.
This role may require up to 10% travel for purposes such as new hire onboarding, client or partner work if applicable, team meetings, and industry events. Travel is coordinated in advance.

Senior Level Customer Engineer Jobs: Frequently Asked Questions
How do I get a senior level customer engineer job?
Employers hiring at the senior level look for candidates who can independently own enterprise accounts, lead technical discovery conversations, and guide implementation without close oversight. A strong edge comes from demonstrated experience closing complex deals alongside sales teams, a history of reducing churn through proactive technical engagement, and the ability to mentor junior engineers while still handling the most demanding customer escalations yourself.
Which companies hire senior level customer engineers?
Companies hiring senior level customer engineers right now include Google, Fastly, and NVIDIA, based on current listings on Migrate Mate as of July 2026. Hiring at this level tends to concentrate among enterprise software vendors, cloud infrastructure providers, and technology consulting firms that manage large, technically complex customer environments.
Are there remote senior level customer engineer jobs?
Yes, though availability varies by industry and employer. About 45% of senior level customer engineer openings are remote or hybrid as of July 2026, reflecting strong demand from companies that operate distributed engineering and customer success teams. On-site roles remain common where hands-on implementation or data center work is part of the position.
What makes a customer engineer role senior level?
Senior level customer engineer roles are defined by ownership and scope. You are expected to lead the technical strategy for a portfolio of accounts, make architectural recommendations independently, and represent the engineering voice in executive-level customer conversations. Mentoring associate and mid-level engineers, contributing to pre-sales strategy, and driving product feedback loops based on field experience are also standard expectations at this stage.
Which industries hire the most senior level customer engineers?
Senior Level customer engineer roles concentrate in Technology & Software, Artificial Intelligence, and Cybersecurity, based on current listings on Migrate Mate as of July 2026.
