Remote-first UK with hybrid London office option
Up to £125,000 + equity
Golang | GCP | Kubernetes | Distributed Systems
Senior Platform Engineer - We're working with a rapidly scaling AI-native SaaS company who raised an impressive Series B round in 2025. Their platform is redefining the sector, and with revenues nearly 10x since the start of last year, they're continuing to expand their Engineering team to match the ambition of their product and customers.
The product is real-time, data-rich and AI-native, creating complex engineering challenges across distributed systems, reliability, infrastructure, tooling and developer experience. As they continue to scale their Engineering team, they are now looking for a Senior Platform Engineer with strong software engineering fundamentals to help build the systems that allow product engineers to ship quickly, safely and reliably.
The Senior Platform Engineer
As a Senior Platform Engineer, you'll treat the internal platform as a product, with engineers as your customers.
This is a hands-on engineering role for someone who can design, build and operate scalable systems, not just manage cloud infrastructure. You'll work across infrastructure, automation, CI/CD, observability and production reliability, while writing high-quality software in Go and helping improve the way engineering teams build and run services at scale.
What will the Senior Platform Engineer do?
- Build and evolve platform infrastructure using Go, Terraform, Kubernetes and GCP
- Design reliable systems that support a complex, real-time SaaS product
- Own CI/CD pipelines end-to-end, making builds, tests and deployments faster and safer
- Build automation and internal tooling that removes manual toil for engineering teams
- Improve observability across metrics, logging, tracing and production monitoring
- Define and manage SLOs across latency, availability and error rates
- Lead incident response, triage complex production issues and ship long-term fixes as code
- Partner with product engineering teams to improve the path from code to production
What will the Senior Platform Engineer bring?
- Strong software engineering experience, ideally with Go as a key language
- Experience designing and operating distributed systems in production
- Strong cloud infrastructure experience, ideally with GCP or AWS
- Deep hands-on experience with Docker and Kubernetes at scale
- Experience with Terraform and infrastructure as code
- Strong understanding of networking, IAM, managed services and secure cloud architecture
- Experience owning observability, logging, APM or distributed tracing tooling
- An SRE mindset across SLOs, reliability, incident response and toil reduction
- Clear communication skills and the ability to influence how engineers build and operate services
This is an amazing opportunity for a Senior Platform Engineer to join a fast-growing scale-up at a pivotal stage, working on complex distributed systems, real-time infrastructure, developer tooling and AI-native architecture.
