Now, as we shape the future of home improvement, we're building the tech to transform that landscape for everyone - better products, smarter data, AI where it actually helps - so trades can spend less time on admin and consumers can find someone they trust, first time. That's Powering Great Work, and it's why every team here exists:\nTrades spend less time on admin and more on winning work and growing their business\nHomeowners get a trusted trade, first time, every time\nWe get to build products that change homes and lives across the country\nAs our next Senior Software Engineer in Trust & Safety, you'll own the systems that decide how tradespeople are checked, how reviews are processed and how our marketplace stays honest at scale. You'll work alongside the vetting and reviews teams, who are on the front line of trust, and build the infrastructure that lets them work with confidence. When something breaks in production, you'll lead the response. When something looks brittle at design time, you'll say so.\nThe job, unfiltered:\nOwn and evolve the systems behind how tradespeople are verified, how reviews flow through our platform and how content is moderated.\n\nLead the response when things break: read distributed traces, correlate logs across services and find the cause, not just the symptom.\n\nDesign event-driven workflows that are reliable by default: idempotent, retryable, with dead-letter handling that doesn't need a 2am wake-up to unpick.\n\nWork directly with the vetting and reviews teams to understand what trust means day to day, then build systems that hold up to it.\n\nTighten the operational seams: better monitoring, clearer alerting, locked-down auth and outbox patterns that keep data consistent.\n\nThe fit:\nStrong TypeScript. You're comfortable owning a service end to end, from schema to deployment.\n\nFastify or a similar Node.js framework, and enough HTTP know-how that it rarely surprises you.\n\nEvent-driven instincts: you know what idempotency means in practice and why the outbox pattern exists.\n\nFull-stack comfort, Next.js included. You ship the frontend as happily as the service behind it.\n\nDatadog fluency (APM traces, log search, metric queries), SQL for diagnostics during an incident, and GCP basics such as Pub/Sub backlogs and DLQs.\n\nExperience leading production incidents, not just being in them. You communicate clearly under pressure and drive to a fix.\n\nAn eye for systemic problems at review time, not at post-mortem time, and a habit of making the people around you better.\n\nRegular use of AI tools like Cursor or Claude Code, and a keen interest in helping the team get more out of them.\n\nYou don't need to know our Trust & Safety domain yet (the review lifecycle, vetting disposition logic, publish timing). You'll pick it up. What matters is that you learn fast and take it seriously.\n(Don't self-select out because you don't tick every box. We'd rather meet you.)\nWhat you get\nCompetitive salary, annual bonus & equity scheme\nHealth, wellbeing and learning support\nGym membership, Smart Tech Scheme, Cycle Scheme\nBirthday/special day leave, buy & sell holiday scheme\n1 week's paid charity leave, and more\nHow this goes\nScreening call with one of our Talent Acquisition Partners\n\nTechnical interview with members of the team\n\nFinal stage with the hiring manager and a senior stakeholder\n\nNot this one? Stay close anyway. Join the Talent Community and we'll ping you the second something better fits.\nAbout us\n We’re Checkatrade - the UK’s leading platform for finding a tradesperson. With more than 50,000 trades listed and over 6 million reviews, we help homeowners get jobs done right and help tradespeople grow their business.\nWe’re growing fast, with big plans to become the go-to brand for home improvements. If you care about great work, take pride in the details, and want to make an impact, you’ll fit right in.","description_format":"text","description_chars":3942,"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":["Equity","Gym membership"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Local Services Marketplaces"],"lifecycle":[{"event":"open","at":"2026-10-02T18:09:30Z"}],"visa":[],"liveness":{"score":72,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.803,"p_room":0.9,"age_days":17,"expected_fill_days":27,"reasons":["conf:2","velocity","win:mid"],"computed_at":"2026-10-20T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/checkatrade-senior-trust-safety-engineer","json_url":"https://alion.io/job/checkatrade-senior-trust-safety-engineer.json","meta":{"generated_at":"2026-10-20T11:47:43Z","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":13029,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-21T00:00:00Z"}},"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":673215},"rest":"https://alion.io/mcp/rest/get_company?id=673215"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcheckatrade-senior-trust-safety-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%2Fcheckatrade-senior-trust-safety-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%2Fcheckatrade-senior-trust-safety-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/checkatrade-senior-trust-safety-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcheckatrade-senior-trust-safety-engineer"}]}
