Go (Golang) Engineer - Blockchain Project

About the role

Sliema Tech Labs is a Malta-based technology firm focussed on blockchain infrastructure, crypto-native backend services and enterprise-grade distributed systems. We work with international clients in fintech and Web3, providing both greenfield development and maintenance of production blockchain nodes and APIs.

You will join a small, multidisciplinary engineering team that values pragmatic design, strong testing practices and continuous delivery. The role involves building backend services in Go, integrating with blockchain clients and smart-contract systems, and participating in architecture and security discussions. You will be expected to take ownership of services, review peers' code and help improve CI/CD and observability.

This role is ideal for engineers who enjoy low-level systems work and distributed systems challenges, but who also value shipping reliable production software. We offer a hybrid working model, professional development support and exposure to cutting-edge cryptographic and consensus-layer technologies. Candidates with strong Go experience and some exposure to blockchain concepts will find good opportunities for growth and technical impact.
