• Work on established, high-volume services at the heart of Form3's cloud-native payment platform where reliability, resilience, and operational excellence matter every single day. • Solve complex engineering challenges across services that support real-time payment flows, high availability, fault tolerance, security, and performance within a microservice architecture. • Evolve critical systems at scale where thoughtful design, careful testing, operational discipline, and reliability are just as important as delivering new capability.

• Have a deep understanding of designing and building distributed systems. • Enjoy working on complex challenges within critical software where high performance and robustness are essential. • Be familiar with cloud and containerisation technologies, test automation tools, and CI/CD pipelines. • Have experience with Go along with a right-tool-for-the-job mentality. • Have interest in owning projects end-to-end and supporting them as they go live in production. • Have an appreciation of clean code and software engineering best practice. • Have great communication skills and enjoy sharing knowledge and collaborating with others.

• Have experience with CockroachDB, NATS JetStream, or similar distributed database and messaging systems. • Bring experience with Kubernetes in production across multi-cloud environments including AWS, GCP, and Azure. • Have experience with infrastructure-as-code tools such as Terraform and GitOps tooling like Flux. • Have experience working in financial services or payments infrastructure. • Have experience with TDD/BDD, pair programming, and SecDevOps practices.

• Design, build, and run cloud-native microservices in Go that are the backbone of the real-time payments platform. • Build systems that are highly available, low-latency, and scalable, handling billions of payment requests with precision and resilience. • Take full ownership of services from initial design and implementation to deployment and production support. • Work with a mindset where cost-efficiency, observability, and operational excellence are core to how you build. • Collaborate closely with other engineers in a flat, autonomous team structure with a strong focus on code quality, simplicity, and continuous improvement. • Work with modern tooling and technologies such as Golang, Kubernetes, CockroachDB, and NATS JetStream in a highly automated DevOps environment.

• Work 100% remotely from the UK or eligible European countries including Germany, Netherlands, Portugal, and Spain. • Receive a competitive salary based on location, ranging from £80k–£120k in the UK. • Access a comprehensive benefits package. • Work in a flat, autonomous team structure with minimal bureaucracy. • Join a culture of knowledge sharing, continuous improvement, and collaborative technical decision-making. • Receive equipment on your first day at the office with team introductions arranged.
