Job summary

Plasma is seeking a mid-level to senior fullstack engineer to join one of our engineering teams and own the product and client-side surfaces from API to pixel. Our stack is TypeScript across the board with Node.js on the backend and React + React Native on the frontend.

You’ll report into your team’s eng lead and partner with your product lead to ship production-quality experiences, prioritising reliability, performance, and a positive user experience for a global money platform.

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
