This isn't one of those roles.\n\nAt Cauli, we're tackling one of the UK's most stubborn environmental problems: the 10.7 billion items of packaging waste generated every year — less than 9% of which is actually recycled. We're not tweaking the system. We're replacing it.\n\nUsing IoT and AI-driven technology, we've already prevented over half a million pieces of single-use waste. Now we're scaling — and we need a software engineer who wants to help build the infrastructure that makes reuse as easy as throwaway.\n\nWhy Join Cauli?\nWe're a small, ambitious team led by founders who are deeply in the weeds with you. You'll work directly with our Head of Technology, with real ownership over meaningful parts of our product — not tickets in a backlog.\n\nWe also know that asking you to take a mission-driven role means we need to reward you for the growth we're building together. That's why equity is a genuine part of your package here — not a footnote.\n\nOur equity options are meaningful.\nAs an early team member, you'll receive options that reflect the ground-floor stage we're at. We're growing fast — and when Cauli wins, you win with us.\n\nA Note on Our Environment\nLet’s be transparent: this is a fast-paced, high-demand start-up environment, and it isn't for everyone. We work in a small, tight-knit team where expectations are high, priorities shift fast, and there are no large corporate safety nets or dedicated account support teams to delegate to. We need a true \"do-er\"—someone who excels in face-to-face client interactions, loves being out in the field, and thrives under pressure.\n\nThe Role\nYou’ll be a driving force across Cauli’s engineering, shipping new features and improvements across our mobile apps, backend, web, and hardware-connected software.\n\nDay to day, this means:\nDeveloping and maintaining the software behind our suite of technology\nBuilding and evolving our mobile apps (iOS and Android), including our unified Kotlin Multiplatform (KMP) codebase\nBuilding and maintaining backend services in PHP/Laravel that power our core product\nBuilding and maintaining our web app and Apple/Google Wallet integrations as part of our container tracking solution\nSupporting our smart bin hardware software (Linux SBCs running Python)\nThis is a broad, hands-on role — ideal if you like variety and want to see your work in the real world quickly.\n\nWho We're Looking For\nWe're looking for someone with at least 1–2 years of professional software engineering experience. We care far more about what you've shipped and how you work than years on a CV.\n\nYou might be a generalist who’s comfortable moving across mobile, backend, and web, or someone with deep strength in one area who’s excited to stretch into others. Either way, you’re someone who takes pride in clean, production-quality code — and wants the work to mean something.\n\nYou'll need:\nStrong software engineering fundamentals and production-level experience in at least one modern language (e.g. Kotlin, PHP, Python)\nComfort moving across different parts of the stack — mobile, backend, and web — rather than staying in one lane\nREST API design and integration experience\nA genuine interest in picking up new languages, frameworks, or platforms as our needs evolve\n\nThese would make you stand out:\nNative Android or iOS development experience (Kotlin, Swift, or Kotlin Multiplatform)\nPHP/Laravel familiarity\nExposure to Apple Wallet / Google Wallet integrations or QR-based flows\nPython familiarity, for crossover with our smart bin codebase\nCI/CD experience (e.g. GitHub Actions)\nExperience with payment SDKs or Stripe\nA background in hospitality, food service, sustainability, or IoT — not required, but a genuine plus\n\nWhat We Offer\nEquity Options: \nCompetitive options as part of the salary package.\nTime Off: \n30 days annual leave (including bank holidays) + your birthday off + Christmas shutdown (around 35 days total).\nCulture: \nA small, diverse, supportive team — regular socials, a founders-led environment, and work that matters.\nPerks: \nCompany pension (NEST), Techscheme, and Cyclescheme.\n\nA Few Practicalities\nYou must currently have the right to work in the UK. We're unable to offer visa sponsorship for this role.\nThis role is hybrid, with time in our London Zone 1 office.\n\nHow to Apply\nWe don't use algorithms to screen people out. We want to hear your voice.\nTo apply, send the following to \n\n[email removed - click apply for more details]\n with the subject line: \nSoftware Engineer Application\nYour CV\nA cover letter — tell us why you're the right person to help us end the era of single-use waste.\nWe can't wait to hear from you!","description_format":"text","description_chars":4712,"description_truncated":false,"requirements":{"experience_years_min":1,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Annual leave","Equity"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-09T00:08:00Z"}],"visa":[],"liveness":{"score":14,"band":"cold","label":"Long shot","p_open":0.6,"p_active":0.503,"p_room":0.45,"age_days":32,"expected_fill_days":19,"reasons":["seen:32","win:tail","comp:junior"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":52864,"is_top_pay":false},"html_url":"https://alion.io/job/cauli-software-engineer-climatetech","json_url":"https://alion.io/job/cauli-software-engineer-climatetech.json","meta":{"generated_at":"2026-10-17T17:24:03Z","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":23945,"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":4372485},"rest":"https://alion.io/mcp/rest/get_company?id=4372485"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcauli-software-engineer-climatetech"},{"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%2Fcauli-software-engineer-climatetech"},{"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%2Fcauli-software-engineer-climatetech"},{"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/cauli-software-engineer-climatetech\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcauli-software-engineer-climatetech"}]}
