Speechmatics are seeking a Site Reliability Engineer (SRE) whose focus will be improving the reliability of our products, systems and infrastructure. You will work across teams to improve availability, scalability, performance and efficiency of our real-time AI inference APIs. You will get to work with high-scale GPU deployments spread across the world. Our customers expect low-latency responses, making this an interesting problem space to learn about.

What You’ll Be Doing

• Working with a diverse group of engineers across Speechmatics to improve reliability of our products and systems, from design through to operation in production.
• Taking part in incident response, postmortems and ensuring the same incident doesn’t happen twice.
• Managing and improving GitOps release workflows and CI/CD pipelines.
• Monitoring system performance and troubleshooting production environments.
• Implementing observability improvements using OpenTelemetry tooling.
• Automating processes that reduce manual efforts and create self-healing systems.
• Taking part in on-call rota for production systems with a generous daily pay rate and mentorship programme to build your confidence in doing it.

Who We Are Looking For

• Comfortable navigating and troubleshooting Linux systems directly from the command line.
• Hands-on experience with major cloud platforms such as AWS, Azure, and GCP.
• Skilled in managing containerised applications using tools like Docker, Kubernetes, and Helm.
• Proficient in Infrastructure-as-Code practices — our production stack includes Terraform, Datadog, ArgoCD, and GitLab.
• Strong focus on automation; you streamline workflows with Bash scripts and turn to Python when things get more complex.
• Curious about the entire technology landscape — from bare-metal servers to cloud abstractions — and motivated to understand how each layer fits together.
• Naturally inquisitive and eager to dive deep into new technologies; you thrive on learning as you go.
• Prior experience with on-call rotations and incident response is a plus.
• Familiarity with OpenTelemetry and related observability tooling is advantageous.

We encourage you to apply even if you do not feel you match all of the requirements exactly.
