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.\n Role Overview:\nThis 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.\nThis 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.\nNote: this role includes on-call responsibilities.\nKey Responsibilities:\nHelp 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).\nDefine, 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.\nPartner with SWEs to implement observability best practices, develop standard templates and documentation, and configure tooling (e.g., OpenTelemetry libraries).\nAutomate the deployment, scaling, and management of the entire observability stack using Infrastructure as Code (e.g. Terraform) and GitOps principles (e.g. ArgoCD).\nPartner closely with the core infrastructure team to ensure deep visibility into our Kubernetes clusters and underlying GCP and AWS environments.\nDevelop and lead the company's monitoring, alerting, and incident response strategy, driving a culture of proactive reliability and blameless post-mortems.\nRequired Qualifications:\n4+ years of experience in an SRE or platform engineering role, with a focus on observability for large-scale, distributed compute or network systems.\nDeep, hands-on expertise building, scaling, and managing observability platforms (e.g., Prometheus, Grafana, Loki/ELK, OpenTelemetry, Tempo/Jaeger, Honeycomb, etc.). You have proven experience using these tools to support performance analysis and debugging of complex distributed systems.\nStrong production-level experience with Google Cloud Platform (GCP) and Kubernetes.\nExperience using Infrastructure as Code (IaC) and GitOps principles (e.g., ArgoCD).\nProficiency in a systems programming language, with a strong preference for Go and Python for debugging and writing tooling.\nDemonstrable experience defining, implementing, and managing SLOs, SLIs, and error budgets for production services for high availability distributed systems.\nPreferred Qualifications:\nExperience operating a multi-cloud environment, specifically GCP and AWS.\nHands-on experience with GitLab CI for CI/CD pipelines.\nWorking knowledge of service mesh technologies such as Istio or Linkerd.\nFamiliarity with instrumenting applications written in Go and C++.\nAn active Secret clearance, or higher, is preferred for this position. \nExperience with JVM observability (tuning, monitoring) for Java-based applications.\nWhat We Offer:\nCompetitive salary benchmarked to UK aerospace and defence technology market rates\nEquity participation - share in Aalyria's growth at an early stage\nComprehensive benefits including pension, private health insurance, and generous annual leave\nFlexible and hybrid working arrangements\nThe opportunity to work on genuinely novel technology with real-world operational impact across national security, commercial satellite, and deep-space programmes\nA collaborative, low-hierarchy team environment with direct exposure to technical leadership and customers\nEqual Opportunity Employer Statement:\nAalyria Technologies is an equal opportunities employer. We are committed to building an inclusive workplace and welcome applicants from all backgrounds. We do not discriminate on the basis of race, religion, gender, sexual orientation, age, disability, or any other protected characteristic under UK law.\nAalyria Technologies operates in sectors subject to UK export control regulations. Candidates may be asked to confirm their eligibility to access export-controlled technology as part of the hiring process.","description_format":"text","description_chars":5116,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":true,"languages":[]},"benefits":["Annual leave","Equity","Health insurance","Hybrid work"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Telecom Infrastructure"],"lifecycle":[{"event":"open","at":"2026-09-10T19:36:54Z"}],"visa":[],"liveness":{"score":27,"band":"fade","label":"Fading","p_open":1,"p_active":0.622,"p_room":0.44,"age_days":100,"expected_fill_days":79,"reasons":["conf:0","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/aalyria-site-reliability-engineer-spacetime-uk","json_url":"https://alion.io/job/aalyria-site-reliability-engineer-spacetime-uk.json","meta":{"generated_at":"2026-10-17T21:25:54Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":6081,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":668833},"rest":"https://alion.io/mcp/rest/get_company?id=668833"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Faalyria-site-reliability-engineer-spacetime-uk"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Faalyria-site-reliability-engineer-spacetime-uk"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Faalyria-site-reliability-engineer-spacetime-uk"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/aalyria-site-reliability-engineer-spacetime-uk\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Faalyria-site-reliability-engineer-spacetime-uk"}]}
