Site Reliability Engineer- Spacetime UK

Site Reliability Engineer- Spacetime UK Site Reliability Engineer- Spacetime UK About Aalyria: Aalyria is a leading technology company that supplies laser communications technology and temporospatial software-defined networking platforms to the aerospace industry. With technology acquired from Google, Aalyria is at the forefront of innovation in satellite and airborne mesh networks, as well as cislunar and deep-space communications. We are revolutionizing the orchestration and management of planetary mesh networks using any radio or optical spectrum, any orbit, and any hardware across land, sea, air, and space. Role Overview: This isn't a "keep the lights on" SRE role. This is a strategic, high-impact opportunity to build the nervous system for a platform that transforms how networks of satellites, ground stations, and fleets are interconnected and orchestrated. You will be building the core observability stack that ensures the reliability of systems critical to the operation of satellite megaconstellations and missions to deep space. This is a greenfield/brownfield opportunity. You will be a trusted expert, helping to define and implement the strategy and building the tools that empower our engineers. You will support the roadmap to mature our observability stack, moving from cloud-native tools to a robust, scalable, and insightful platform built on best-in-class technologies (Prometheus, OpenTelemetry, etc.). If you are an SRE who thrives on platform-building challenges and wants to be relied upon to build a production-grade observability stack from the ground up, this role is for you. Note: this role includes on-call

responsibilities. Key

Responsibilities: Help design and build Aalyria's centralized observability platform, integrating and scaling tools for metrics (e.g. Prometheus), logging (e.g. Loki), and distributed tracing (e.g. Tempo/OpenTelemetry). Define, implement, and manage a robust framework of Service Level Objectives (SLOs), Service Level Indicators (SLIs), and error budgets for our core products, ensuring we are launch-ready. Partner with SWEs to implement observability best practices, develop standard templates and documentation, and configure tooling (e.g., OpenTelemetry libraries). Automate the deployment, scaling, and management of the entire observability stack using Infrastructure as Code (e.g. Terraform) and GitOps principles (e.g. ArgoCD). Partner closely with the core infrastructure team to ensure deep visibility into our Kubernetes clusters and underlying GCP and AWS environments. Develop and lead the company's monitoring, alerting, and incident response strategy, driving a culture of proactive reliability and blameless post-mortems. Required
