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, All new joiners start their first day in our office to collect the equipment needed to work remotely. We'll also arrange for some of your team to come in to say hi, ensuring you're supported and have a positive first few days with Form3! ## Related Videos - [Empowering Thousands of Developers: Our Journey to an Internal Developer Platform](https://www.wearedevelopers.com/videos/1519-empowering-thousands-of-developers-our-journey-to-an-internal-developer-platform) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Go with the Flow: Stop the Leaks Before Your Memory's a Waterfall!](https://www.wearedevelopers.com/videos/100073-go-with-the-flow-stop-the-leaks-before-your-memory-s-a-waterfall) - [Retooling and refactoring - an investment in people.](https://www.wearedevelopers.com/videos/371-retooling-and-refactoring-an-investment-in-people) - [#90DaysOfDevOps - The DevOps Learning Journey](https://www.wearedevelopers.com/videos/548-90daysofdevops-the-devops-learning-journey) ## Related Articles - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [The Best Software Developer Blogs to Read](https://www.wearedevelopers.com/magazine/156-the-best-software-developer-blogs-to-read)
