Senior Software Engineer (Go)

THE ROLE  📝    As a Senior Software Engineer at Form3, you’ll work on established, high-volume services that sit at the heart of Form3’s cloud-native payment platform. These are critical systems where reliability, resilience and operational excellence matter every single day.   This is a role for engineers who enjoy evolving critical systems at scale. You’ll be working on mature, high-volume services where thoughtful design, careful testing, operational discipline and reliability are just as important as delivering new capability.   You’ll solve complex engineering challenges across services that support real-time payment flows, high availability, fault tolerance, security and performance within a microservice architecture. You’ll need to think carefully about how changes are designed, tested, released and operated, balancing delivery speed with the discipline required for mission-critical financial infrastructure.    You’ll work closely with experienced engineers, product teams and operational stakeholders to improve, evolve and run services that customers depend on. This could include enhancing existing payment capabilities, improving service resilience, simplifying complex systems, reducing operational risk, or building new functionality into mature services without compromising stability.       WHAT YOU’LL BE DOING 🏗️     Designing, building, and running cloud-native microservices in Go that are the backbone of our real-time payments platform    Building systems that are highly available, low-latency, and scalable, handling billions of payment requests with precision and resilience    Taking full ownership of services: from initial design and implementation to deployment and production support    Working with a mindset where cost-efficiency, observability, and operational excellence are core to how we build    Collaborating closely with other engineers in a flat, autonomous team structure, with a strong focus on code quality, simplicity, and continuous improvement    Working with modern tooling and technologies such as Golang, Kubernetes, CockroachDB and NATS JetStream in a highly automated DevOps environment        WE’RE LOOKING FOR  🔍    Deep understanding of designing and building distributed systems    Enjoys working on complex challenges within critical software where high performance and robustness are essential    Familiarity with cloud and containerisation technologies, test automation tools and CI/CD pipelines    Interest in owning projects end-to-end and supporting them as they go live in production     Appreciation of clean code and software engineering best-practice     Experience with Go, along with a “right tool for the job” mentality     Great communication skills who enjoy sharing knowledge and collaborating with others        TECH STACK ⚙️     Here are a few of the tools and methodologies we utilise:     Infrastructure:  AWS, GCP, Azure, Kubernetes     Platform:  CockroachDB, NATS JetStream, Elasticsearch, Vault, Cilium    Tools:  Terraform, Flux, GitHub, Prometheus, Pact.io, Tilt    Code:  Go (and a little Java), containerised microservices, CQRS, open source     Ways of working:  TDD/BDD, Pair Programming, 100% remote, SecDevOps        THE TEAM 👥     At Form3, our engineering team is the backbone of everything we do.
