About the Role

Plasma is seeking a mid-level to senior fullstack engineer to own product and client-side surfaces within one of their engineering teams. The role involves building and shipping production-quality experiences from API to pixel, focusing on performance, responsiveness, and user trust.

Responsibilities

  • Build and own your team's product and client-side surfaces end to end, in React and React Native - from the API down to the pixel.
  • Care as much about how a screen feels as whether it's correct: performance, responsiveness, and the small interactions that make the product feel trustworthy with someone's money.
  • Design and build the systems: state management, data schema design and robust handling of real financial data
  • Partner closely with product and design at the concept level, so the experience and the implementation move as one thing, not two departments.
  • Own reliability: graceful handling of failures, retries, and edge cases in a product where mistakes cost people real money.
  • Raise the bar on engineering quality within your team: architecture, testing strategy, performance budgets, and code review.
  • Mentor other engineers and drive technical clarity on the product side of your team.
  • You have very high agency and don’t wait to be told a problem to work on and proactively find new problems to solve

Requirements

  • A mid-level to senior, hands-on engineer with a track record of shipping and owning production, fullstack systems end-to-end.
  • Strong product sense: you notice when something feels slow, confusing, or untrustworthy, and you fix it without being asked.
  • Comfortable taking product surfaces from zero to one, and then scaling them without losing clarity or performance.
  • Strong judgment on tradeoffs: speed vs. polish, abstraction vs. control, simplicity vs. flexibility.
  • You communicate clearly, write clean code, and can lead through technical and product decisions.
  • Experience building product-facing or client-side systems at scale
  • You make decisions based on data and use data to ground whether solutions work

  • 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.

About the Company

  • 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, 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.
  • 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.

Equal Opportunity

  • 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.
