Descrição da oferta de emprego

Senior Full Stack Engineer

70,000 - £90,000

Remote - Brazil (You will need to work UK time zone)

You already know how to build software that works.

What you might be missing is the chance to build something that matters, where the details count and the users notice when you get it right.

This role is for an engineer who cares how things look, how they behave, and how they hold up when real money and real users are involved.

Why you’ll love it here :

• You’ll own real parts of the product, not just tickets
• The UI has to be precise and trusted, not “close enough”
• You’ll work across the full stack with real influence over decisions
• The product sits between traditional finance expectations and onchain systems
• You’ll build for institutional and high net worth users who demand clarity and reliability

Who this isn’t for :

This isn’t a role for someone who wants a narrow remit, loose UI standards, or to ship features without thinking end to end.

If you prefer clear tickets, minimal ownership, or letting AI do the thinking for you, this will feel uncomfortable.

Day to day :

You’ll be building and refining a production platform used to manage onchain assets.

That means turning product direction and designs into polished, accurate UI, then wiring it properly into APIs, databases, and background workflows.

The split is genuinely full stack. You’ll spend meaningful time on the frontend, but you’re also expected to contribute confidently on the backend so features are built end to end, not in isolation.

Performance, maintainability, and correctness matter because this platform is already live and evolving.

The Business :

The business is a FinTech fund building onchain banking infrastructure for institutional capital.

It operates where stablecoins, DeFi lending, automation, and risk management meet.

The focus is usability and trust, bringing institutional-grade expectations into onchain finance, with active engagement from major financial institutions.

Requirements :

• Strong full stack experience with React, Next.js, Node.js, and TypeScript
• Proven ability to ship precise, production-quality UI
• Solid SQL knowledge with Postgres and an ORM such as Prisma
• Experience designing APIs and backend workflows, including orchestration tools like Temporal
• Understanding of ERC-4626 and DeFi lending markets such as Aave or Morpho
• Confident, structured use of LLM tools like Cursor or Claude Code
• FinTech experience preferred
• Able to travel freely across Europe

If you want ownership, technical breadth, and the chance to build a mature system people genuinely rely on, this is worth a conversation.
