About Plasma
Plasma is building the primary account for global money.
Money used to belong to a country. Increasingly, it belongs to a person or business moving through many countries. People and businesses now earn, spend, save, hire and invest across borders. Traditional banks cannot serve this new world.
Our first product, Plasma One, is a global money account: a place to receive, hold, send funds in seconds, earn yield and spend with a card in the local economy.
Underneath is the Plasma network, built from first principles for stablecoin payments. Stablecoins make dollars faster, cheaper and more reliable to move.
Technological revolutions obey power laws. The opportunity is to become where all global money lands first: where income arrives, balances grow, payments move, businesses operate, and new financial products are built.
The Team & Our Story
We are a global team of founders, operators and engineers, obsessed with building the best products. We work at the cutting edge of financial innovation, using stablecoins to create tools for consumers and businesses.
We operate with trust, clarity, and ambition: own your craft, move with urgency, contribute beyond your lane, back your teammates, debate rigorously, and keep raising the bar for what great means.
Consumer owns the core Plasma One product experience - onboarding, activation, retention, rewards, tiers, trading, earn, and account management. The team is responsible for growing funded users, engagement, balances, spend, and long-term retention.
Payments owns the financial infrastructure that powers Plasma - accounts, ledgers, funding, payouts, card issuing, reconciliation, payment orchestration, and currency/rail integrations. The team is responsible for the reliability, scalability, and economics of moving and storing money.
Business owns the Plasma experience for companies - the operating account for businesses that work globally: onboarding, receiving, holding, and sending money across borders, corporate cards and spend management, and the roles and approvals that keep teams in control of company money. The team is responsible for taking the product from its first business customers to general availability, and for growing the businesses that run on Plasma.
The Role
We're looking for a staff+ engineer, backend-leaning but comfortable full-stack, to join one of Plasma's engineering teams and take ownership of that team's hardest technical problems. Our stack is TypeScript across the board - Node.js on the backend and React + React Native for the frontend
You are expected to set technical direction for your team's most critical systems, while partnering with product and, where relevant, other teams at the points where your systems connect.
The Work
Own the hardest technical problems inside your team end to end - the ones that need deep judgment, not just execution.
Set technical direction for your team's core systems: architecture, data models, and standards that hold up as the team scales.
Design for reliability first: idempotency, consistency, and graceful failure recovery in systems that move or store real money, or that the network depends on.
Go deep on the backend, but stay full-stack, own the TypeScript service and the data model, and work through the client or API layer when the problem calls for it.
Define how your team's systems handle the hard edge cases: partial failures, retries, timeouts, reversals, reconciliation gaps - whatever “correct under pressure” means for your team.
Contribute, architect and improve the frontend systems and integrations wherever necessary
Raise the technical bar within your team: code standards, testing strategy, monitoring, incident response, and how the team approaches ambiguous problems.
Mentor other engineers and drive technical clarity on the hardest parts of your team's system.
The Bar
A staff-level, hands-on engineer with a track record of owning production systems end to end, not just contributing to them.
Backend-leaning but full-stack: deep expertise building backend services in TypeScript (Node.js), with enough range to work through the client layer when needed.
Strong instincts around reliability and correctness - you think in systems: state machines, data integrity, observability, operational risk.
Comfortable taking systems from zero to one, and then scaling them without losing clarity.
Strong judgment on tradeoffs: speed vs. safety, abstraction vs. control, simplicity vs. flexibility.
You communicate clearly, write clean code, and can lead through technical decisions without needing to manage people.
You have very high agency and don’t wait to be told a problem to work on and proactively find new problems to solve
You make decisions based on data and use data to ground whether solutions work
Nice to have
Fintech, banking, or crypto-native background.
Familiarity with stablecoins, custody, settlement, and blockchain transaction lifecycles.
You’ve been a founder or early employee at a fast-paced, high agency startup
What's in it for you
Above-market salary for the level of the role, with token compensation.
A beautiful London HQ with gym access and daily food, for those who thrive in an office environment. Visa sponsorship and relocation support if you're joining from abroad.
Premium health insurance for you and your family, fully covered by Plasma.
Monthly wellness budget, whether that's the gym, therapy, sauna, or massage.
All the tools and tech you need to operate at your best.
Real ownership and responsibility from day one, with your work shipping to hundreds of thousands of people, moving millions of dollars every day.
Data Protection & Privacy We are committed to protecting the privacy and security of your personal data. Any personal information you provide during the recruitment process will be processed in accordance with the General Data Protection Regulation (GDPR) and applicable local data protection laws.
