About Block Labs

Block Labs is a leading force in the Web3 space, incubating, investing in, and accelerating top-tier fintech, crypto and iGaming projects. With a mission to shape the future of decentralized technology, we partner with visionary startups to raise funding, refine product-market fit, and grow their audiences. Our diverse team drives innovation, using deep industry expertise and an extensive network to empower the next wave of blockchain-driven companies. At Block Labs, we’re passionate about turning bold ideas into breakthrough success.

About The Role

We’re currently building a state-of-the-art, modular, multi-tenant iGaming platform. This role sits at the core of the engineering team responsible for developing highly scalable services, intuitive frontend interfaces, and seamless third-party integrations, including games.

As a Senior Fullstack Developer, you’ll work closely with the Tech Lead and cross-functional squads to deliver microservices and frontend components. While your main focus will be on Go, Java, and React, we’re looking for someone with a polyglot mindset — open to using PHP, Node.js, or other stacks when needed. Occasionally, you may also touch game-side logic or work on integrations for new providers.

Key Responsibilities

Develop, test, and maintain backend services and frontend interfaces.
Contribute to the implementation of multi-tenant features with clear data separation and high configurability.
Integrate third-party services and APIs, including game providers, wallets, and analytics tools.
Ensure performance, security, and observability of the systems.
Write clean, maintainable code and participate in peer reviews.
Support documentation, deployment automation, and continuous integration workflows.
Build and maintain internal tools and libraries that enhance development efficiency and support other developers.

About You

5+ years of Fullstack development experience across modern backend and frontend technologies.
Strong hands-on experience with Go, Java, and React.
Comfortable switching between technologies and working across multiple codebases.
Experience designing APIs, working with microservices, and integrating third-party systems.
Familiar with multi-tenant architectures, role-based access control, and secure systems.
Exposure to observability practices, distributed tracing, and structured logging.
Familiarity with cloud-native platforms, messaging systems, modern databases, and infrastructure-as-code tools.
Background in iGaming is a plus.
Clear communicator and proactive contributor in remote-first environments.
