We’re looking for an exceptional Senior / Lead Golang Engineer to join a major global bank and play a key role in building highly scalable, resilient technology platforms supporting critical financial services.
This is a senior engineering position for someone who enjoys solving complex distributed-systems problems, setting technical direction and building production-grade software at significant scale.
You’ll work with experienced engineers, architects and technology leaders to design and deliver modern services using Go, cloud-native technologies, Kubernetes and distributed systems.

What you’ll do
- Lead the design and development of high-performance services and platforms using Golang
- Take ownership of technically complex projects from architecture through to production
- Define engineering standards, patterns and best practices across Go services
- Design highly available, scalable and resilient distributed systems
- Work closely with architects, product teams and other engineering groups to shape technical strategy
- Mentor and support other engineers, helping raise engineering standards across the team
- Build and operate cloud-native applications in a highly regulated financial environment
- Contribute to our Generative AI strategy, including services and platforms that leverage LLMs and AI capabilities
- Improve observability, reliability, performance and operational excellence across our platforms
- Participate in technical design reviews and contribute to engineering-wide initiatives
