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 build distributed, transactional backend platforms across crypto, fintech, and real money gaming. High volume, multi tenant, real time. Balances, payments, and player facing decisions depend on them, so correctness is not negotiable and mistakes are visible immediately. The work spans several products and follows business priorities, so what you own will change over time. You will build and own distributed, transactional backend services in Go, as an individual contributor.

Ownership has a specific meaning here. You receive an outcome and its constraints, not a decomposed backlog. You identify the decisions nobody has made and gather the context to make them. You define scope and sequencing. You make the architectural and implementation decisions. You implement the system rather than delegating it. Others will contribute to it, and you own the conditions that let them do so without degrading it. You ship it, and you remain responsible for how it behaves in production.

Agents are the normal means of production here, not an optional aid. That does not reduce the need for engineering judgement, testing, or operational ownership. It increases how much of each one engineer carries.

You will collaborate with product, engineering, infrastructure, and QA throughout, and you will need to be good at it, because nobody will be coordinating it on your behalf.

What You Will Do

• Convert business outcomes and constraints into scoped, sequenced, shippable work.
• Design and implement distributed Go services handling high volume transactional workloads, integrating with payments, providers, and internal platforms.
• Make the correctness guarantees explicit and hold them. Balances and transactional behaviour have no margin for approximation.
• Run the agentic system that produces the work: context, decomposition, execution, verification.
• Set the harness and guardrails others work inside: context, tests, and automated checks that let people contribute to your system without it degrading into debt you inherit.
