About Block Labs

Block Labs is a premier technology studio operating at the bleeding edge of Web3, Artificial Intelligence, and iGaming. We don't just ship features; we engineer high-scale, production-grade platforms that power the next generation of digital products.

We are a collective of senior engineers, product strategists, and builders who refuse to compromise on architecture. Whether we are designing autonomous multi-agent AI systems, building decentralized financial infrastructure, or architecting high-frequency iGaming platforms, our standard is excellence.

We move fast, but we build for the long term. If you are looking to work alongside a team that values deep technical expertise, thoughtful system design, and product ownership, Block Labs is where you belong.

The role

We are building the frontend of a multi-brand consumer platform in React, Next.js and TypeScript: one codebase serving several brands, where launching a brand should be a matter of configuration, not a copy.



You will be the most senior frontend engineer in the company and the person the platform’s UI depends on.

We don’t hire into squads. We work as a small number of very strong individual contributors, each owning a product end to end and shipping with AI agents at a pace that used to take a team. You get an outcome and constraints, not a backlog: you find the decisions nobody has made, scope the work, build it, ship it and stay accountable for how it behaves in production. Product ideas often arrive as working prototypes built with AI tools by people outside engineering. Your job is to steer them into production, not to reject them or rebuild them from zero.

Key Responsibilities:

• Own the frontend end to end: architecture, conventions, quality bar and production behaviour of a multi-brand platform, with no spec handed to you.
• Make adding a brand a configuration change: theming, brand-aware routing and content, and clean boundaries between shared and brand-specific code, all on
