The Senior Engineer will create solutions that use artificial intelligence to solve real business problems, with AWS/Databricks as the core production platform and Claude and Codex supporting the engineering workflow. This is a hands-on role spanning discovery, software delivery and the reliable operation of live services\nResponsibilities\nOwn the design, build, deployment and ongoing operation of production-grade AI-enabled data products on AWS and Databricks.\nWork with stakeholders to define the user problem, measurable outcomes, data requirements and a pragmatic technical approach.\nPrototype rapidly with Claude, Codex and other approved AI tooling, then turn successful concepts into secure, maintainable software.\nBuild reliable data pipelines, APIs and back-end services, together with front-end web or app experiences where the product requires them.\nApply strong software engineering practices including code review, automated testing, CI/CD, version control, documentation and infrastructure as code.\nCreate evaluation, monitoring and observability for data quality, model or LLM behaviour, service reliability, performance and cost.\nProtect sensitive data and apply appropriate security, privacy, governance and responsible AI controls throughout the product lifecycle.\nOperate and support live services, resolve faults swiftly, reduce technical debt and share practical knowledge with the wider team.\nAbout the team\nThe Ecotricity Technology department is a small friendly team with a strong focus on getting results, with everyone committed to delivering both individually and as part of the group/project.\nWe have a training programme in place to further advance your skills, with dedicated learning time planned into our workloads.

Depending on the problem, this may pipelines, APIs, backend services and user-facing websites or applications.\nWe value sound engineering judgement over using AI for its own sake. You will select the simplest effective approach, prove value quickly, and then engineer for security, performance, cost, maintainability and scale. Experience in the energy industry is helpful but not essential.\nYou will work closely with product owners, project managers, subject-matter experts, data teams and other stakeholders. You will explain options clearly, demonstrate working software, gather feedback and translate it into measurable product outcomes.\nThis is a hybrid role, you will be self-motivated, delivery-focused and comfortable driving work independently.

This allows the company to utilise our people in the best possible way at all times and helps our colleagues to make the best contribution in a changing environment.\nEcotricity is Britain's overall greenest energy company- it’s more than just green energy - the breadth and depth of our work on green issues is unmatched. When we started back in 1995, we were the first company in the world to provide a new kind of electricity - the green kind.\nOur mission was, and remains, to change the way energy is made and used in Britain - by replacing fossil fuels with clean, renewable energy.\nWe don't just supply green energy, we use the money from our customers' bills to make it ourselves too - we have built windmills and sun parks in Britain. We call this turning 'bills into mills'.\nWe don't just focus on energy though- we built the Electric Highway, Britain's leading network of electric vehicle charging points; we helped Forest Green Rovers become the greenest football club in the world; and we launched Britain's greenest mobile phone service, Ecotalk, where they use the money from their customers' bills to protect and regenerate Britain's lost rainforests.\nEcotricity is an equal opportunities employer and is committed to providing equality for all.","description_format":"text","description_chars":6966,"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":["Hybrid work"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Power Grid","Solar Energy"],"lifecycle":[{"event":"open","at":"2026-11-04T12:24:14Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"evidence":"Licensed UK visa sponsor (Skilled Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Skilled Worker","cap_exempt":false,"checked_at":"2026-11-06T06:20:25+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":3,"expected_fill_days":31,"reasons":["conf:8","win:early"],"computed_at":"2026-11-06T05:58:05Z"},"pay":null,"html_url":"https://alion.io/job/ecotricity-senior-engineer","json_url":"https://alion.io/job/ecotricity-senior-engineer.json","meta":{"generated_at":"2026-11-06T08:02:31Z","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":14399,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-07T00:00:00Z"}},"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":1776671},"rest":"https://alion.io/mcp/rest/get_company?id=1776671"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fecotricity-senior-engineer"},{"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%2Fecotricity-senior-engineer"},{"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%2Fecotricity-senior-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/ecotricity-senior-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fecotricity-senior-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3743245}},{"tool":"search_jobs","arguments":{"company":"ecotricity.co.uk","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3743245},"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.
