Senior Product Engineer, Treasury (Elixir)
WFA Digital Insight
Vic.ai’s Treasury team is tackling some of the most forward‑looking problems in finance: AI agents that can create and spend corporate cards without human touch. The senior engineer they seek will not only write Elixir/Phoenix services but also shepherd a feature from product concept through the UI that users actually click. Working directly with the founders means rapid feedback and ownership of the architecture that moves billions of dollars each day. Candidates should be comfortable with distributed, asynchronous systems, Kubernetes, and the emerging Claude Code AI‑assistant, because Vic.ai expects engineers to embed AI into their daily workflow rather than treat it as an afterthought.
Job Description
SENIOR PRODUCT ENGINEER, TREASURY (ELIXIR) Remote — US-based, working EST hours ABOUT VIC.AI http://Vic.ai Vic.ai http://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. THE ROLE 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. WHAT YOU'LL DO - 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.
- 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.
- Clear communicator across technical and non-technical teams; fluent English. NICE TO HAVE - Python or other backend languages.
- Payments, treasury, or fintech domain experience.
- Event-driven architectures, message queues, workflow orchestration.
- Exposure to AI/ML-powered products.
- Generous PTO and a remote-first, flexible schedule.
- Comprehensive health and wellness benefits.
- Real autonomy and ownership — a direct hand in where payments and treasury go. Acceptance and inclusion for everyone is at the heart of our company.
How to Stand Out
- Highlight any production Elixir or Phoenix projects in your portfolio, especially those involving APIs or async processing.
- Demonstrate familiarity with Claude Code or similar AI coding assistants by mentioning specific prompts or workflow improvements.
- Prepare concrete examples of end‑to‑end feature ownership, showing how you handled both backend logic and front‑end integration.
- Be ready to discuss your experience with Kubernetes, CI/CD pipelines, and PostgreSQL performance tuning during the interview.
- Emphasize clear communication skills by framing technical decisions in business terms.
- Ask about the team’s approach to observability and incident response to gauge their reliability standards.
- When negotiating, reference the equity component and AI tooling budget as part of the total compensation package.
