Job Specifications
Rebind's mission is to make modern finance simple, open, and self-custodial.
We're starting by building the most intuitive way to earn, manage, and move money -- all powered by crypto rails, and accessible from a mobile app that feels like any great fintech product.
We're hiring a Senior Mobile Engineer (Paris, hybrid) to help us craft the frontend experience that brings fully onchain finance to life.
Why join
We're a small team working hands-on from our office in Paris. You'll collaborate closely with backend, design, and product to shape core flows from concept to production.
Impact -- Own the frontend of our mobile app and shape how thousands of users interact with open finance.
Excellence -- Build with people who care about clean design, real performance, and high product polish.
Autonomy -- Work across product, design, and logic -- and take full responsibility for what you ship.
What you'll do
We're looking for a frontend engineer who's excited to build world-class mobile UX for a self-custodial finance product -- fast, intuitive, and production-ready.
Build and maintain the Rebind mobile app. Use React Native and Expo to create smooth, responsive interfaces with a clean, high-performance architecture.
Implement polished UI. Build pixel-perfect components from Figma, handle interactions, animations, and ensure native-feeling performance.
Work with APIs. Integrate backend services that expose transaction flows, vault data, yield performance, and wallet metadata.
Collaborate with backend and product. Ensure flows are consistent, fast, and reliable from screen to API response.
Understand the full system. You don't code onchain, but you know how the stack works -- from smart accounts to vaults -- and what matters to users.
Ship, test, repeat. Build fast, test carefully, and continuously improve the experience through iteration and feedback.
What we're looking for
Ownership mindset. Takes full responsibility for outcomes, not just screens.
Fast learner with bias to action. Moves quickly, adapts fast, and improves with every cycle even under uncertainty.
Resilient under pressure. Pushes through when things break or get unclear. Keeps a cool head in high-stakes environments.
Mission-driven. Deeply committed to building open, mobile-first finance on crypto rails.
Pragmatic problem solver. Optimizes for simplicity and user value over complexity or hype.
Clear thinker, low ego. Welcomes feedback, challenges ideas constructively, and stays calm when being challenged.
Care for craft. Obsesses over detail in spacing, typography, states, and interactions.
Cross-functional awareness. Communicates clearly with backend and design, and understands how systems behave behind the interface.
Good heart. We don't tolerate jerks and are generally just friendly people.
We value diverse perspectives
If you come from an underrepresented background in tech or finance, we strongly encourage you to apply.
What we offer
We'll treat you well. If there are any other benefits that are important to you, we'd like to hear.
A front-row seat to the future of finance -- work on a cutting-edge tech product at a well-positioned European startup.
Competitive salary and meaningful equity -- multiple options based on your desire and commitment.
Hybrid culture -- we value in-person work in our Paris office, but support remote days and periods away when needed.
Time off when you need it -- no tracking, just alignment.
Focused, high-trust environment -- low overhead, clear goals, and fast iteration.
Plenty of autonomy, zero bureaucracy -- you'll own what you build.
Hardware setup -- new MacBook Pro, big display, and accessories.
