Senior Product Engineer, Vic.ai

• US-based and able to work EST hours — you'll be embedded with an EST-based treasury team
• 5+ years of professional experience, with strong production Elixir and Phoenix
• Ships features end-to-end — product framing through front-end — without a handoff
• Solid grounding in distributed systems, concurrency, and async processing
• Strong PostgreSQL; hands-on with cloud infrastructure, Kubernetes, and CI/CD
• Demonstrated, fluent use of AI coding tools (esp. Claude Code) in real day-to-day work
• Clear communicator across technical and non-technical teams; fluent English

Desirable

• We're looking for a senior engineer with deep Elixir experience to build and scale the core services behind our treasury platform (moves billions in transaction volume)
• Increasingly that means agent-driven spend: AI agents that initiate corporate expense and travel, plus the infrastructure for them to create and use payment cards — some of the most forward-looking work at the company
• Elixir is the anchor, but we want someone who thinks beyond the backend: an engineer with organized product thinking who can own a problem end-to-end across the SDLC — from shaping the requirement, to the backend service, to the front-end it ships behind, to running it in production
• You'll work directly with the founders on product direction, alongside a small, senior team across treasury, product, and data/AI
• Design, build, and operate Elixir/Phoenix services — APIs, data pipelines, and async processing
• Own features end-to-end, from product framing through the front-end needed to ship
• Treat reliability as first-class on Tier 0/1 systems: observability, monitoring, and operational rigor
• Use AI-assisted tools (esp. Claude Code) and help shape architecture, practices, and code review
