Our platform indexes, curates, annotates, and evaluates data across the full AI lifecycle, from development through production. Trusted by Woven by Toyota, AXA, UiPath, Zipline, and more.\nWe'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 an outstanding engineer to push our platform to the next level. You'll join us at a crucial stage of accelerated development for the company, product and team. As part of a small, highly collaborative group, you'll drive our product and team to new heights.\nEncord is growing rapidly, with our product as the key driver of that growth. A year ago, we were a team of 25; now, we’re 60 and continuing to accelerate.\nWhat you'll do\nBe a part of the small team that has built a product that our customers love and consistently rate as the best in the market\n\nHave a direct and tangible impact on customers and, in turn, noticeably affect the trajectory of the company\n\nWork autonomously and take end-to-end ownership of your projects. From product, design and architectural decisions, all the way to deployment, monitoring and measuring impact on users. You will work across the stack, covering everything from deployment to styling. We expect each other to take initiative, be proactive in problem-solving, and continuously seek improvements\n\nTackle complex domains and immense scale with simple solutions\n\nWho we're looking for\nYou've seen and built a lot. You have personally developed and maintained multiple systems from scratch, and you know what trade-offs are involved in building reliable, performant software at speed\n\nYou want your work to have a tangible outcome for people. You're not satisfied with building products that do not see the light of day\n\nYou are a builder. You enjoy all aspects of building not only software but a complete product, and are comfortable moving across the stack when necessary.\n\nYou enjoy problem-solving and thinking from first principles, and are always ready to pick up new skills and build quickly\n\nYou're happy to tackle problems without a predefined, clear definition or obvious solution, and are excited to have autonomy to make decisions as you go\n\nYou understand that being a member of a high-performing team requires two things. You contribute your best work and help others contribute their best. You'll always lend a helping hand when needed and level up those around you\n\nExperience requirements\nStrong experience building large-scale backend infrastructure applications\n\nDeep fluency in at least one high-level language (we use Python and TypeScript, but we care more about depth than the specific language)\n\nExperience improving quality through code reviews, testing, rollout, and monitoring\n\nExperience with prompt engineering, agent orchestration, and the ability to integrate AI tools to optimise workflows and drive measurable impact\n\nExperience in robotics, autonomous vehicles, or Physical AI is a plus\n\nTech stack\nWe are technology-agnostic at Encord and are not looking for experience across all of these - as long as you're open to learning, please apply.\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\nCompany lunches twice a week\n\nMonthly socials & bi-annual team offsites","description_format":"text","description_chars":3718,"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":"2026-08-27T19:21:18Z"}],"visa":[],"liveness":{"score":18,"band":"cold","label":"Long shot","p_open":1,"p_active":0.396,"p_room":0.45,"age_days":50,"expected_fill_days":27,"reasons":["conf:1","win:tail"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/encord-software-engineer-backend","json_url":"https://alion.io/job/encord-software-engineer-backend.json","meta":{"generated_at":"2026-10-17T20:58:39Z","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":5350,"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":557},"rest":"https://alion.io/mcp/rest/get_company?id=557"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fencord-software-engineer-backend"},{"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%2Fencord-software-engineer-backend"},{"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%2Fencord-software-engineer-backend"},{"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-software-engineer-backend\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fencord-software-engineer-backend"}]}
