Senior Software Engineer - Work from home

Relay is a digital banking platform that gives self-made business owners the tools and know-how to be great with money—bringing clarity, confidence, and control to every dollar earned, so they can turn hard work into lasting success. We do this by replacing financial guesswork with real visibility, transforming cash flow from a constant source of stress into a clear signal owners can use to run stronger, more resilient businesses.
Our Engineering team is at the heart of building banking products that help millions of small businesses succeed. We’re on a journey to reinvent banking, and we’re looking for a curious, impact-driven Senior Software Engineer (Voyager) to join our growing team – someone who thrives on taking smart risks, experimenting boldly, and learning from every challenge.
We build the technology foundations that make AI and insights possible across the product, and we partner with product teams so they can build quickly on top of them. If you’re excited to tackle new problems and care as much about building strong foundations as delivering an impressive end product, you’ll feel at home on Voyager. If you believe the most interesting part of applied AI is the engineering behind it, this is the role for you.
AI Infrastructure: Build and deploy secure, reusable LLM systems that enable differentiated product experiences, and own them across the full lifecycle, from design through deployment and monitoring
Developer Enablement: Give teams across Relay the tooling, patterns, and guidance they need to ship AI workflows quickly and safely
Consultative Partnership: Work alongside product teams as the AI expert in the room, helping them make good technical decisions rather than building everything for them
Innovation & Continuous Improvement: Proactively identify areas for technical, process, and product improvement, helping the team raise the bar and influencing technical direction and long‑term strategy
You have 3+ years of full-stack software engineering experience; agentic AI experience is a plus
You proactively drive enhancements and lead initiatives to enhance code quality, optimize performance, and streamline development processes
You take ownership end‑to‑end, solving problems creatively and proactively, while keeping the customer and business impact front‑of‑mind
It’s a bonus (but not required) if you

Have worked in startups or high‑growth tech companies
Have hands‑on experience building with LLMs, including self‑hosting or serving open models, retrieval systems, evaluation, or agentic workflows
Have experience with JavaScript – we primarily use TypeScript, React, and Node.js
Have working knowledge of AWS services (ECS, S3, RDS, Dynamo, Lambda) and continuous deployment pipelines
Front‑end: React, Typescript, React Native
Back‑end: Node.js, Typescript, Terraform, AWS (DynamoDB, RDS Postgres, Lambda, S3, SQS, SNS, SES, ElasticSearch, ECS)

If you’re someone who takes initiative, is comfortable taking risks, and seeks input when needed, you’ll find the freedom here empowering.
You build with AI, not just use it: You're actively embedding AI into how you work, pushing what's possible, and bringing your team along with you.
You’re comfortable building from scratch, iterating as you go, and collaborating to shape the best path forward.
Relay exists to help them thrive -- and that mission has to resonate with you.
