About the Role
We are looking for a Full Stack Engineer to join our core engineering team. This role requires someone strong across the entire stack, comfortable on the frontend and backend, and who uses AI tooling as a natural part of their work. You will own features end-to-end, from the database layer through to the UI, and work directly with product and engineering leads.
Responsibilities
- Design, build, and ship features across our product ecosystem, working across the full stack as the product demands.
- Build clean, performant frontends that users love.
- Build solid backend services and APIs that hold up under load.
- Build the plumbing in between that keeps everything connected and reliable.
- Contribute to system design and architecture discussions.
- Help shape how we evolve our products.
- Take features from idea through to production.
- Use AI development tooling daily to move faster, debug smarter, and take on more complex problems.
- Bring an AI-first mindset to everything you ship.
Requirements
- Solid professional experience across both frontend and backend development.
- A real portfolio of shipped products rather than just contributed codebases.
- Equally comfortable building a React frontend and designing the API it calls.
- Write clean, maintainable code.
- Think about how things will hold up in production.
- Care about quality as much as speed.
- Use AI tools actively and practically every day.
- Can speak concretely about how AI tools change the way you work.
- Working knowledge of CI/CD, version control, and deployment practices.
- Comfortable taking ownership of your work through to production without needing someone else to handle the operational side.
- Experience with agentic AI workflows is a strong differentiator.
- Blockchain and Web3 experience is genuinely valued.
- Ability to work with Solidity, EVM, or similar on-chain tooling is a plus.
- Prior on-chain deployments, hackathon projects, or open source contributions in the Web3 space are worth mentioning.
- You are a builder and have shipped real things you can talk about.
- Take ownership of your work.
- Move fast without cutting corners.
- Use AI to expand what you are capable of rather than to replace your own thinking.
- Comfortable working in a small, high-trust team where the scope of what you touch is broad and the feedback loop is short.
- This role is probably not for you if you prefer working within a narrow specialism, need a lot of structure before you can start, or have not yet integrated AI tooling into your daily workflow.
