Job description

Hyperlayer is the intelligent banking platform built for the agentic economy: the financial control layer that sits above banks' existing cores, enabling next-generation Smart Accounts, without ripping anything out. From a single integration, we give financial institutions a secure rules and orchestration engine that lets them design, launch and scale hyper-personalised products in weeks while preserving stability, compliance and control. And there's nothing like us anywhere in the world.

Hyperlayer works with Tier 1 and Tier 2 FIs across the UK, US, EMEA and Hong Kong, with an award-winning UK consumer app (HyperJar) sitting in the group. We're creating the fintech category that every bank in the world needs: programmable, governed, agent-ready accounts. Your job is to make sure our audiences know that.

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

Design & Development

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