Job description

About the role

• We’re looking for a Backend Engineer who specialises in Golang to help build and scale the core services that power Hyperlayer’s orchestration engine. You’ll be working on high-throughput, mission-critical systems that sit at the heart of how our financial institution clients design, launch and manage Smart Accounts — so performance, reliability and correctness really matter.
• You’ll work closely with product, platform and other engineering teams to design APIs, evolve our service architecture, and ship features that our clients depend on in production. This is a hands-on role for someone who enjoys writing clean, well-tested Go and cares about the operational health of what they build, not just shipping code.

What you’ll do

• Key Responsibilities:
• Contribute to the ongoing development of Hyperlayer’s flagship platform, delivering the backend services at the heart of our programmable banking product.

Design & development

• Design, build and maintain high-performance backend services and APIs in Go, as part of Hyperlayer’s core orchestration platform.
• Contribute to the architecture of new features and services, balancing pragmatism, scalability and long-term maintainability.
• Write clean, well-tested, idiomatic Go code, and participate actively in code review to help maintain a high engineering bar.

Systems & reliability

• Work with event-driven and asynchronous patterns (message queues, event streaming) to build resilient, decoupled services.
• Design and evolve data models and queries against relational databases, with an eye on performance and correctness at scale.
• Support the operational health of services in production, including monitoring, alerting and incident response for systems you own.

Collaboration & delivery

• Partner with Product and other Engineering teams to translate requirements into well-scoped technical designs.
• Collaborate with DevOps/Platform on deployment, containerisation and infrastructure for the services you build.
• Contribute to technical decisions, documentation and best practices across the wider Engineering team.

Qualifications

• Strong professional experience building backend services in Go (Golang), including a solid grasp of concurrency and Go idioms.
• Experience designing and building RESTful APIs and/or microservices in a production environment.
• Working knowledge of relational databases (e.g. PostgreSQL), including schema design and writing efficient queries.
• Experience with containerisation and orchestration tools such as Docker and Kubernetes.
• Familiarity with cloud platforms (AWS, GCP or Azure) and modern CI/CD practices.
• Experience with message queuing or event streaming technologies (e.g. Kafka) is a strong plus.
• Prior experience in fintech, financial services, or another regulated, high-reliability environment is desirable but not essential.
• Strong communication skills and comfort collaborating closely with cross‑functional teams.

We will not be offering UK work visa sponsorship for these roles. Candidates will need an existing non-sponsored right to work in the UK.
