Senior Software Engineer

Mural Engineering Role You'll be joining a lean, high-intensity engineering team at an inflection point — processing billions in volume today. You'll work directly with our CTO, contributing full-stack from week one. The team is exceptional — from Palantir, McKinsey, DoorDash, Mercado Libre, Circle, and BlackRock — and we're only adding people who make it stronger. This role is about three things: 1. Building Infrastructure That Moves Money You'll work on the core systems that power global payments — state machines, transaction pipelines, reconciliation flows. Accuracy is non-negotiable when money is on the line, but so is the ability to build systems that adapt as the financial landscape evolves. You'll own features end-to-end, think carefully about failure modes, and write code you're proud to put your name on. 2. Shaping the Product You're not just implementing tickets. You'll collaborate closely with our CTO, BD team, and directly with customers to evolve our API and platform — making complex financial flows feel intuitive for the developers and businesses building on top of us. If you see a better way to build something, you'll say so. If a tradeoff matters, you'll surface it. We want engineers who think like owners. 3. Setting the Bar As an early engineering hire, you'll have an outsized influence on how we build — the patterns we establish, the standards we hold, the culture we cultivate. We believe quality engineering lives at the intersection of theory and experimentation: think rigorously, ship decisively. You'll help define what that looks like in practice. You're a strong individual contributor who works well across the full team. You don't need someone looking over your shoulder. You take ownership of your work end-to-end, communicate honestly about timelines and constraints, and never let something fall through the cracks because it wasn't technically "your problem." You're comfortable with the full stack. You have at least 4+ years shipping production-grade infrastructure with Node + NestJS (or something comparable) and React + TypeScript. You're proficient building client facing APIs and asynchronous backend systems with complex state machines (event queuing, job scheduling, webhook delivery, failure recovery, etc.). You move fluidly between frontend and backend depending on what the problem requires. You care about design and have high standards for what you ship — not just whether it works, but whether it feels right. You're built for startups. You know what it means to operate in an environment with high ambiguity and real stakes. You move fast, make good decisions under uncertainty, and find energy in the challenge rather than frustration in the chaos. You've worked in a high-growth environment before — or you're deeply ready for one. You're obsessed with correctness and resilience. Moving money globally means the margin for error is low. You think carefully about edge cases, error handling, and what happens when things go wrong — because they will. You love a good state machine. You appreciate systems that are both robust and easy to reason about. You're curious about what we're building. You don't need to come from a fintech background, but you should be genuinely interested in stablecoins, global payments, and the financial infrastructure being rebuilt around them. The engineers who thrive here see the mission as part of the appeal — not just the tech stack. You're shipping meaningful features from week one — contributing to our platform and API with minimal ramp-up time The systems you build are reliable, readable, and maintainable — code that the team is proud of and that scales with us You've raised the bar — through the patterns you introduce, the reviews you give, and the standards you hold You've become a key voice on engineering decisions — someone our CTO relies on when it matters We run on three principles. 2% better, every day. One percent for yourself, one percent for the people around you. Telos. From the Greek τέλος — not just done, fulfilled. Everyone here is focused on one mission and knows each other's Telos. Abundance. We can create anything we set our minds to — for us, for our partners, and for our entire Mural family. We're builders all the way down — code is a medium, like paint. We choose honesty over polish: we never claim what isn't true. We obsess over boring details, because trust is built in RFIs, refunds, and response times. And we hire for curiosity — it's a bar, not a poster. Competitive cash base salary Meaningful early-stage equity Health insurance 401(k) Visa sponsorship available New York City or Denver, in person.
