Senior Software Engineer

That's the world Mural is building. This role is one of the hands on the brush.

Mural is regulated financial infrastructure across the US and Latin America. The whole stack, one partner. Companies build cross-border financial products on us using our API. We carry the licenses, the compliance, and the failure states, so they go live in weeks instead of months. Under the hood, fiat and blockchain run as one system. Their customers never see any of it. Money comes in, money goes out, and it just gets there.

We've processed over $2 billion across US dollar, stablecoin, and international rails. That includes USDC and USDT on major blockchains, ACH and wire in the US, and local rails across Latin America and Europe (PIX, SPEI, Bre-B, CBU/CVU, SEPA). Customers include Deel, Bolt, Opera, Koywe, Taxdome, Uniswap, Movii, and more. We recently closed our Series A. And we're an AI-native company. Agentic tools are how we build, operate, and scale.

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, with people 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 and NestJS (or something comparable) and React with TypeScript. You're proficient building client facing APIs and asynchronous backend systems with complex state machines (event queuing, job scheduling, webhook delivery, failure recovery, and so on). 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, with 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 word telos, meaning not just done but 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 ourselves, our partners, and our entire Mural family.

We're builders all the way down. Code is a medium, like paint. We choose honesty over polish and 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.

We named this company Mural because murals have always told the story of a community. They are made by hand, made together, painted onto the foundations of a place, and meant to outlast the people who started them. Every person who joins brings a new piece.

Now let's build a force of nature business, together.
