The Role

As a Frontend Engineer, you will be a key contributor to the user interfaces across our DeFi ecosystem. You will focus on implementing well-defined features and components, helping the team deliver a seamless, consumer-grade UX while learning about the complexities of blockchain backend constraints.

You will join a collaborative, cross-functional team of friendly, adaptable, creative, and product-minded engineers who are passionate about building high-quality, user-centric software that delivers real impact.

Your Opportunity

• Contribute to product development by assisting with feature implementation and collaborating with technical leadership on execution details.

• Collaborate effectively with full-stack engineers, R&D engineers, and product specialists to deliver stable and tested services.

• Implement UI components and features using defined design patterns and reusable UI frameworks.

• Develop your skills by learning and applying new systems, design patterns, and tooling, while supporting the team's commitment to engineering best practices.

We're Looking For

• Foundational software development experience, including contributing to and maintaining user-facing systems

• Frontend expertise, with a solid working knowledge of React (ideally with Next.js), TypeScript, and responsive UI design.

• Understanding of UI design patterns, with the ability to build and maintain simple, reusable components.

• Ability to contribute to rapid prototypes to validate ideas, and then help promote successful features into robust, production-grade architecture under mentorship.

• Familiarity with cloud concepts, and basic exposure to cloud providers (GCP, AWS/Azure are acceptable) is a plus.

• Comfort with modern tooling and an eagerness to leverage AI-assisted workflows (Copilot, Cursor, etc.) to accelerate personal velocity.

• Working knowledge of browser internals, the critical rendering path, the DOM, and networking concepts.

Nice to Have

• Experience launching greenfield products from scratch.

• Technical understanding of blockchain technologies including DeFi and EVM ecosystem.

While we think the above experience is important, we’re very keen to hear from people who believe they have valuable experience to bring to this role. If you identify with the team and mission, but not all of our requirements, then please still apply.
