Job Description:

Global Web3 startup

London - Hybrid working

DATAHEAD has been exclusively retained by a global deep-tech startup pioneering the future of developer tooling through AI infrastructure.

This early-stage company is creating a new layer of abstraction for developers to easily build intelligent, automated workflows that connect across modern and decentralised ecosystems.

Backed by notable investors and run by a world-class founding team with experience across FAANG, DeFi, and Ivy League institutions, they’re entering their next phase of growth and scaling their engineering team.

The Opportunity:

As their first dedicated Front-End Engineer, you’ll lead the development of high-performance, user-centric interfaces for their AI-driven products. Working directly with the founding team, you’ll help define and implement end-to-end UI/UX strategy and set architectural standards for scalable front-end systems.

What You’ll Do:

• Drive front-end development and architecture for new AI products.
• Define UI/UX strategy and implement best practices with a bias toward modular, maintainable code.
• Collaborate cross-functionally with design, product, and back-end teams.
• Build reusable components and interface libraries (hooks, APIs, sockets).
• Contribute to code and architectural reviews and mentor other engineers.

What You’ll Bring:

• Expertise with ReactJS and state management libraries (Redux, Zustand, etc.).
• Strong understanding of performance under high-load environments (1,000+ socket events/min).
• Ability to operate in ambiguity and thrive in fast-paced, early-stage settings.
• Excellent communication skills and an eye for detail in documentation and design.

What’s On Offer:

• Equity & competitive compensation
• Flexible work environment with a modern, collaborative workspace
• Freedom to take the time you need to recharge
• Social events, office perks, and parental leave

Be part of a team rewriting the future of how software is deployed, scaled, and adopted.
