About Plasma
Plasma is building money that just works. Plasma One is our flagship product: a stablecoin neobank where people send and receive money in seconds globally, earn yield every day, and spend with a Visa card in over 150+ countries. Now live in private beta with 100,000+ people on the waitlist. Under the hood sits the Plasma network, a blockchain we designed from first principles for stablecoin payments. Stablecoins will reshape global finance. We're building the full stack that gets them there, from the underlying infrastructure to the app in your pocket. We are redefining how money moves.
Team Culture
At Plasma, you join a team that is rewriting how the world interacts with money. We hire people who are relentless about their craft and expect that same standard from everyone around them. This is where you will do the hardest and most meaningful work of your career. We work with trust, clarity, and ambition. Everyone owns their craft, moves with urgency, and contributes beyond their lane. We back each other, we debate hard, and we hold a high bar for what great looks like. Plasma is built for people who thrive on challenge and want to leave a mark.
The Frontend Team
The frontend team builds the surfaces people trust with their money. This includes our mobile app (React Native), web experiences (React), and the layer between user experience and backend systems. As a Senior Frontend Engineer, you operate across the full stack, but your strength is the frontend. You think deeply about state, performance, reliability, and how complex financial systems are represented clearly and safely to users. This is not a pixel-only role. You will help define frontend architecture, influence product decisions, and set engineering standards across web and mobile. You will work closely with design, backend, and product to ship experiences that feel calm, predictable, and trustworthy, even when the underlying systems are complex.
What you will do
- Build and own core product surfaces using React and React Native, powering critical flows like onboarding, balances, sending, and receiving money.
- Design frontend architecture that scales across platforms while maintaining consistency, performance, and reliability.
- Own complex client-side state, async workflows, and error handling for real-world financial interactions.
- Work full-stack where needed, collaborating closely with backend engineers and contributing to APIs and system design.
- Partner deeply with design to translate intent into precise, production-quality experiences.
- Anticipate and design for edge cases: latency, partial failures, retries, and degraded states.
- Set standards for frontend quality, testing, performance, and maintainability.
- Help make a stablecoin-powered product feel boring in the best way: fast, clear, and dependable.
Who you are
- A senior, hands-on engineer with strong experience building React and React Native applications in production.
- Comfortable operating full stack, but with a clear frontend-first mindset.
- Strong instincts around state management, data flow, performance, and user experience.
- Able to reason about complex systems and present them clearly through UI.
- Comfortable owning features end-to-end, from architecture to production and iteration.
- Calm in ambiguity, opinionated when it matters, and thoughtful about tradeoffs.
Nice to have
- Experience building consumer fintech or financial products.
- Experience with mobile-first or cross-platform product development.
- Familiarity with TypeScript across frontend and backend.
- Experience working close to launch or scaling early-stage consumer products.
- Interest in crypto or stablecoins (or curiosity to get up to speed quickly).
Salary and Benefits
At Plasma, we provide each team member with the tools they need to succeed. Benefits for full-time employees include:
- Above market salary plus token compensation.
- Premium health insurance for you and your family fully covered by Plasma.
- Monthly wellness budget, whether for the gym, therapy, sauna & massage.
- A beautiful London HQ with gym access and daily food, for those who thrive in an office environment.
- All the tools and tech you need to operate at your best.
- Visa sponsorship and relocation support if you are joining the London office from abroad.
