Location: Remote / Hybrid (UK-Based ONLY)
Type: Full-time
The Role
We're looking for a Site Reliability Engineer who knows how to keep complex systems running smoothly—no hand-holding, no drama. You'll be the guardian of uptime, scalability, and deployment flow across our Golang-heavy infrastructure. You’ll work closely with product teams to bake reliability into every layer.
What You’ll Do
- Own the reliability, observability, and scalability of production systems
- Write and maintain internal tooling and infrastructure services in Go
- Design CI/CD pipelines and deployment flows for containerised applications
- Monitor system performance and build automated alerting and recovery workflows
- Perform root cause analysis and drive incident resolution—fast and clean
- Harden services for edge deployment and constrained environments
- Build infrastructure as code (Terraform, Pulumi, etc.) for reproducible environments
- Collaborate with AI, CV, and platform engineers to deliver resilient, high-performance systems
Must-Have Skills
- 3–5+ years in SRE, DevOps, or backend engineering roles
- Strong Golang experience (our stack is Go-forward across infrastructure and services)
- Proficiency with Docker, Kubernetes, and service mesh patterns
- Solid understanding of distributed systems, load balancing, and fault tolerance
- Experience with observability tools (Prometheus, Grafana, Loki, etc.)
- CI/CD pipeline mastery (GitHub Actions, GitLab CI, etc.)
- Able to debug weird, low-level problems across the stack without losing your cool
Bonus Points For
- Experience building edge-ready systems with minimal resource footprints
- Familiarity with message queues (NATS, Kafka, etc.) and event-driven architectures
- Hands-on with ARM-based platforms, embedded Linux, or cross-compiling for the edge
- Terraform, Pulumi, or custom provisioning tools
- Security-minded: you consider threat models and harden attack surfaces by default
