Why This Job is Featured on The SaaS Jobs
This role stands out in SaaS because it sits at the intersection of workflow automation, payments infrastructure, and AI driven product behavior. Vic.ai is operating in a high stakes part of the SaaS landscape where software is directly responsible for moving money and enforcing controls, which raises the bar on reliability, observability, and auditability. The emphasis on Elixir and Phoenix also signals a backend stack chosen for concurrency and fault tolerance, both relevant when transaction volume and asynchronous processing are core to the product.
For a long term SaaS engineering path, the scope here maps closely to what senior product minded engineers build in modern platforms: services, APIs, data flows, and the operational practices required to run them in production. Exposure to end to end delivery, including some front end work, supports progression toward staff level ownership where product framing and execution are inseparable. The mention of AI coding tools and agent driven spend adds a timely angle on how SaaS teams are evolving development workflows and product capabilities.
It is best suited to an engineer who prefers clear ownership over handoffs and is comfortable being accountable for production outcomes. The remote, EST aligned setup fits someone who works well with distributed peers while staying tightly connected to a core team. Candidates motivated by fintech adjacent constraints and pragmatic product thinking should find the day to day shape aligned with their strengths.

Job Description
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.
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. Claude Code) and help shape architecture, practices, and code review.
What we're looking for
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.
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.
What we offer
Competitive compensation, meaningful equity and an extensive AI tooling budget.
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. We strive for diversity of thought, culture and background, which connects the entire Vic.ai community. We are proud to be an Equal Opportunity Employer.
