Form3 · 100% Remote (Canada*)
THE PROJECT 📝 Form3 is looking for several Senior Software Engineer contractors to work alongside our US Software Engineering team to deliver new products within our US Payments proposition. This is an opportunity to work on critical payments infrastructure in a highly technical environment, contributing to the design, build, testing and launch of new Zelle and Fedwire capabilities. You’ll be working in Go on Form3’s cloud-native platform, applying proven engineering patterns from our existing payments services while solving the specific challenges that come with high-volume, resilient, regulated payment systems. Design and implement new US payments gateway functionality in Go, aligned to product requirements and agreed technical architecture. This includes payment flows, scheme-specific behaviours, error handling, validation and operational requirements, as well as comprehensive automated integration tests covering this functionality. Work collaboratively with Product, Engineering and other functions to refine requirements and validate implementation choices. Contribute to technical design activity, including design proposals, implementation plans and problem-solving within Form3 platform architecture. Support non-functional requirements related to resilience, performance, disaster recovery, failure-mode testing and operational readiness. Establish and improve monitoring, alerting, telemetry and observability to support operational visibility from development through to production. Support production-readiness activity, including release preparation, final validation, production deployment and post-launch issue resolution. Produce and maintain technical documentation, including design notes, testing documentation, deployment guidance, operational procedures and runbooks. Ensure all work aligns
