Senior Product Engineer, Treasury (Elixir)

Remote — US-based, working EST hours

Vic.ai is building the autonomous finance platform for the modern enterprise. We use AI to automate accounts payable and treasury workflows so finance teams operate with more speed, accuracy, and insight — today processing hundreds of millions of invoices a year. We're venture-backed, with teams in Miami, Raleigh, and Oslo.

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.
