Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
You will design, build, and maintain cloud-native microservices in Go to support a high-volume, real-time payment platform. You will take full ownership of services throughout the entire lifecycle, ensuring reliability, scalability, and operational excellence.
Candidates must have a deep understanding of distributed systems and experience building robust, high-performance software. Proficiency in Go and familiarity with cloud-native technologies, containerization, and automated testing pipelines are essential.
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.

THE TEAM 👥
At Form3, our engineering team is the backbone of everything we do.

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.
