Our platform indexes, curates, annotates, and evaluates data across the full AI lifecycle, from development through production.\nTrusted by Woven by Toyota, AXA, UiPath, Zipline, and more. We're an ambitious team of 100+ working at the frontier of AI and have raised $60M in Series C funding from Wellington Management, CRV, Next47 and Y Combinator.\nThe role\nWe're looking for a Senior Site Reliability Engineer to join our growing platform engineering team. You'll be embedded in the teams building and operating Encord's core infrastructure, ensuring our platform is performant, reliable, observable, and scalable.\nYou will lead the planning and execution of efforts needed as we grow from our customer base from hundreds to thousands of AI teams worldwide, and the volume of AI training and supervision data managed by our platform from TBs to PBs of data.\nYou'll drive a culture of performant and resilient software through individual contributions and collaboration with multiple squads.\nWhat You'll Do\nPerformance & Capacity - Profile and optimise services handling large-scale data pipelines; perform capacity planning for storage and compute-intensive workloads. Work with squads to establish performance benchmarks and expectations\n\nCollaboration - Partner closely with backend and ML engineers to improve deployment pipelines (CI/CD), review infrastructure changes, and champion reliability best practices.\n\nReliability & Availability - Define and own SLIs/SLOs/SLAs for critical services; build alerting, runbooks, and incident response processes; lead postmortems with a blameless culture.\n\nInfrastructure & Cloud - Design, deploy, and maintain cloud infrastructure on GCP and AWS; manage Kubernetes clusters, networking, and storage at petabyte scale.\n\nAutomation & Tooling - Work to improve developer productivity and guide and review automation and tooling efforts across the engineering group.\n\nObservability - Instrument services with distributed tracing, logging, and metrics (Prometheus, Grafana, OpenTelemetry, Datadog or similar); build infrastructure, define best practices and work with each squad to ensure every service is observable before it goes to production.\n\nWhat We're Looking For\nExperience on hands-on SRE, DevOps, platform engineering experience or similar in a production environment.\n\nStrong fundamentals in designing, building and maintaining resilient distributed and/or high performance systems\n\nSolid understanding of networking, operating systems and database technologies\n\nExperience with observability fundamentals - metrics, logs, traces, and alerting.\n\nComfortable with on-call rotations and incident management.\n\nTech stack\nWe are technology agnostic at Encord and not looking for experience across all of these - as long as you're open to learning, please apply.\nBackend: Python and Rust\n\nFrontend: TypeScript and React\n\nDeployment: Kubernetes\n\nInfrastructure: GCP\n\nWhy Encord\nCompetitive salary, commission, and meaningful equity in a high-growth startup\n\nStrong in-person culture - most of the team works from our London office 4+ days/week\n\n25 days annual leave + UK public holidays\n\nAnnual learning & development budget\n\nTravel for customer visits, events, and conferences across the UK and Europe\n\nDaily company lunches\n\nMonthly socials & bi-annual team offsites\n\nOperating principles\nHigh agency\nYou see something broken, you fix it or find the person who can. We celebrate the people who solve 90% of a problem before anyone asks.\nBuild with care & urgency\nWe bear-hug the customer. Former founders and people from fast-moving, high-stakes environments thrive here.\nSelf-aware & hungry\nWe stay warm, self-aware, and genuinely hungry. We elevate our peers, and ego doesn't last long.\nInvent in real time\nWe move toward the ambiguity. We’re pragmatic, resourceful, energized by the fact that there's no playbook.\nIf you're looking to do the most meaningful work of your career alongside people who push you to be better, we'd love to meet you.","description_format":"text","description_chars":4111,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Annual leave","Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["MLOps","AI Training Data & Annotation"],"lifecycle":[{"event":"open","at":"2026-11-12T12:15:40Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":69,"reasons":["conf:4","win:early"],"computed_at":"2026-11-12T23:21:45Z"},"pay":null,"html_url":"https://alion.io/job/encord-senior-sre-engineer","json_url":"https://alion.io/job/encord-senior-sre-engineer.json","meta":{"generated_at":"2026-11-12T23:21:45Z","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":49411,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-13T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":557},"rest":"https://alion.io/mcp/rest/get_company?id=557"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fencord-senior-sre-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Fencord-senior-sre-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fencord-senior-sre-engineer"},{"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/encord-senior-sre-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fencord-senior-sre-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4160376}},{"tool":"search_jobs","arguments":{"company":"encord.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4160376},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
