Most decarbonisation solutions count emissions but do nothing to reduce them. We've changed that.\nWe’re Neutreeno, an emissions-to-performance platform, born out of the University of Cambridge's Department of Engineering. We help companies with supply chains and production processes turn emissions data into operational insight, the kind that cuts costs, sharpens decisions, and unlocks genuine competitive advantage. For operations and finance, it's margin they can measure. For sustainability teams, it's progress they can prove. Same data, two audiences, one engine.\nWe’re a fast-moving team that values EQ just as much as IQ. Autonomy, high-ownership, speed and no-ego collaboration are at our core. We seek people who care deeply and are eager to work on solving problems bigger than themselves.\nThe Role\nThe engineering problems here are genuinely hard. It involves building robust ingestion pipelines that handle messy, heterogeneous data, a calculation engine that estimates the correct emissions across complex activity hierarchies, and actionable insights that help make the biggest companies in the world better. Wrapped in an experience that must be easy to use.\nAs a Senior Full Stack Software Engineer and key member of the Neutreeno team, you’ll be shipping great software, bringing strong engineering judgment, and making the team better through craft and collaboration.\nYou’ll ship across the full stack, crafting clean React UIs, building reliable Node.js and Python services, and deploying to AWS. You’ll own features end-to-end alongside a small, strong engineering team, and you’ll have real influence over how the product evolves.\nYou also use AI coding tools and agentic workflows as a force-multiplier, and you’re actively curious about how they change what a small engineering team can achieve.\nThis position operates on a hybrid work model with 3 days per week in our Cambridge office. Fully remote arrangements may be considered for outstanding international candidates, provided there is sufficient overlap with UK working hours.\nThe Work You’ll Do\nSoftware Development\nBuild responsive, modular UIs in React and TypeScript that make complex emissions data feel simple and intuitive.\nDevelop and maintain backend services in Node.js, designing clean APIs and working with cloud-native AWS infrastructure.\nShip features end-to-end: from picking up a product brief to deploying to production via our CI/CD pipelines.\nContribute to the technical direction of Neutreeno, helping inform architectural decisions that balance speed, quality, and long-term scalability.\nChampion AI-native development practices and agentic workflows across your own work and actively share that thinking with the wider team.\nCollaboration and Product\nPartner closely with the Neutreeno team to translate product ambitions into well-scoped, well-sequenced engineering work.\nFeed into the engineering roadmap, providing strong technical input on prioritisation, feature velocity, and technical health.\nContribute to hiring decisions and help shape an engineering culture that helps Neutreeno scale.\nCommunicate clearly about technical decisions and progress with product, design, and the wider team.\nRequirements\nThe Minimum Qualifications You’ll Need\n7 or more years of professional software engineering experience.\nA strong individual contributor deeply motivated to stay hands-on in the codebase, with a collaborative approach to sharing knowledge and raising quality across the team.\nDeep proficiency across the full stack, including React and TypeScript on the front end and Node.js on the back end.\nSolid experience with AWS infrastructure and cloud-native deployment.\nA proven track record of shipping high-quality software at pace.\nReal, daily use of AI coding tools and agentic development workflows as a core part of how you work.\nStrong communication and the ability to build trust quickly across engineering, product, and leadership.\nPreferred Qualifications\nExperience at an early-stage startup as a senior individual contributor.\nFamiliarity with GraphQL, Terraform, or CI/CD pipeline design.\nExperience integrating LLMs or building AI-powered product features.\nExposure to climate, sustainability, or deep-tech domains.\nDegree in Computer Science or a related field (not required, track record speaks louder).\nBenefits\nWhat We Offer\nCompensations & Benefits:\nCompetitive pay dependent on your skills, qualifications and experience.\nYear-end performance bonus.\n25 days annual leave.\nMeaningful equity stake. We want you to think and benefit like an owner as the company grows.\nCompany pension with NEST.\nLeading private health insurance with WPA (the only Which? Recommended Provider for Private Medical Insurance).\nCycle to work scheme.\nWork Environment:\nA hybrid work model that fosters both teamwork and individual flexibility.\nRemote working allowance for personal travel, in addition to regular holiday policy (2 weeks per year).\nWork from Neutreeno HQ at the Cambridge Institute for Sustainability Leadership, recognised by the FT as one of Europe's leading startup hubs.\nGreat on-site amenities (unlimited free coffee, monthly events with global sustainability leaders, and more).\nCulture & Growth:\nA fast-growing team (200%+ YoY growth) from diverse backgrounds that recently closed a $5M seed round.\nAn open-minded culture with a flat hierarchy and everyone vectoring in the same direction and where ideas and ownership matter.\nThe chance to work alongside world-class climate scientists and engineers on one of the most important problems of our time.\nHow to Apply\nIf you’re a senior engineer who loves great code, thrives in a fast-moving environment, and has a genuine point of view on how AI tooling fits into modern development, we want to hear from you. To apply, send your CV and a cover letter covering two things: how AI tooling features in your day-to-day development work, and what's drawing you to Neutreeno specifically.\nBy submitting your application, you agree that we may keep your CV in our talent pool for up to 12 months to consider you for future career opportunities; you can withdraw this consent at any time by emailing us at .\nNeutreeno is an equal opportunity employer committed to creating an inclusive workplace.","description_format":"text","description_chars":6392,"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","Health insurance","Hybrid work"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Energy Management","ESG & Carbon Accounting Software"],"lifecycle":[{"event":"open","at":"2026-09-11T00:14:32Z"}],"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":"2026-10-31T06:23:40+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":9,"band":"cold","label":"Long shot","p_open":1,"p_active":0.328,"p_room":0.28,"age_days":165,"expected_fill_days":36,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-11-01T06:10:25Z"},"pay":null,"html_url":"https://alion.io/job/neutreeno-senior-full-stack-software-engineer","json_url":"https://alion.io/job/neutreeno-senior-full-stack-software-engineer.json","meta":{"generated_at":"2026-11-02T00:34:13Z","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":959,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"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":682341},"rest":"https://alion.io/mcp/rest/get_company?id=682341"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fneutreeno-senior-full-stack-software-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%2Fneutreeno-senior-full-stack-software-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%2Fneutreeno-senior-full-stack-software-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/neutreeno-senior-full-stack-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fneutreeno-senior-full-stack-software-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":685848}},{"tool":"search_jobs","arguments":{"company":"neutreeno.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":685848},"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.
