[Hiring] Senior Software Engineer @Form3

Role Description

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
• Building new functionality into mature services without compromising stability

Qualifications

• 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

Requirements

• 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
