Job description

At Form3, our mission is simple but powerful: To design, build and run the technology that will power the future of payments.

As a Senior Software Engineer, you will be part of a team working on the critical infrastructure that underpins global payments. This is a rare opportunity to help shape the systems that move money at scale both securely, reliably and in real time.

• 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
• Deep understanding of designing and building distributed systems
• Enjoy 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

Here are a few of the tools and methodologies we utilise:

• Code: Go (and a little Java), containerised microservices, CQRS, open source
• Ways of working: TDD/BDD, Pair Programming, 100% remote, SecDevOps

At Form3, our engineering team is the backbone of everything we do. A remote first group of highly skilled, collaborative, and forward-thinking individuals passionate about building secure, scalable, and reliable payment technology. We operate in a true DevOps model, where engineers take full ownership of the software lifecycle, from design and implementation to deployment and operation in production.

We value clean code, automation, simplicity, and continuous improvement. Our engineers work in small, autonomous teams with a flat structure and minimal bureaucracy, promoting a culture of trust, transparency, and accountability. We use modern technologies (Golang, Kubernetes, AWS, and more) and embrace a cloud-native, event-driven architecture to support our microservices platform.

Expect a culture of knowledge sharing, where pull requests are thoughtful conversations, and technical decisions are made collectively and with care. If you're motivated by solving complex problems at scale and enjoy working with other talented engineers who care deeply about doing things right, you'll feel right at home here.
