Integrations with ATS and HRIS platforms such as Workday, Greenhouse, iCIMS, Lever and SmartRecruiters are one of our biggest levers for growth, and demand from Partnerships and Sales is outpacing what our current team can build. As an Integrations Engineer, you'll add the engineering capacity to change that.\nYour job is to increase the number and quality of Zinc's integrations. You'll design, build and scale connections with third-party platforms, and evolve our Partner API so partners can build on Zinc with less hand-holding.\nThis is an engineering role. Support and onboarding sit with our dedicated Integration Support function in Partnerships, so your time goes on building, hardening and improving integrations. You'll also be the escalation point for issues support can't resolve. You'll work closely with Product, Partnerships and Integration Support, and report to the Engineering Manager for Integrations.\n\nKey Responsibilities\n\nBuilding integrations end to end - Read partner API docs, spec with the PM, then build, test and release new integrations, from Greenhouse Harvest API upgrades to CV checks across ATSs.\n Hardening what's live - Move existing integrations off deprecated mechanisms (such as Greenhouse polling to PATCH) and strengthen error handling, retries and idempotency.\nEvolving the Partner API - Own endpoint design, versioning, webhooks, docs and sandbox so partners can build on Zinc with less hand-holding.\nBuilding reusable patterns - Create shared connector and mapping layers that cut the cost of every new integration.\nGiving support the tools - Build internal tooling and observability so Integration Support can diagnose issues themselves.\nBeing the escalation point - Root-cause and fix the issues Integration Support can't resolve. You're not the first line for customers.\nShaping what we build - Give Product and Partnerships technical feasibility input during discovery, through the team's planning process.\nRaising the bar - Review code, set testing standards, and pick up occasional Vue/Nuxt work on integration settings screens.\n\nSkills, Knowledge and Expertise\nHard skills\n\nIntegration Engineering - You've built and maintained production integrations against third-party APIs you don't control, in code rather than config. You know the trade-offs: sync vs async, webhooks vs polling, retry strategies.\nTypeScript / Node.js - Production experience. Our backend is TypeScript and we standardise across the codebase.\nREST APIs & Webhooks - OAuth2, pagination, rate limits, retries and idempotency are second nature. They're core to every integration.\nData Mapping - You're comfortable moving data between JSON, XML and SOAP. Workday and iCIMS are XML/SOAP-heavy.\n Testing - You're proficient with Jest and with contract and integration tests using mocks, because integrations fail silently.\n\nWhat we offer\n24 days holiday + Bank Holidays + your birthday off \n£1200 annual benefits allowance (ThanksBen, from month 2)\nEarly finish Fridays (16:00)\nYearly company retreat abroad \n30 days to Work from anywhere \nEnhanced Maternity, Paternity, and Adoption Leave (13 weeks full pay, 17 weeks half pay, then SMP for maternity, 2 months full pay, then statutory pay for paternity/adoption) \nStatutory pension with NEST (3% employer, 5% employee)\nZinc shares, issued through the EMI Scheme\nUnlimited access to Spill Therapy\nCompany socials, quarterly team socials Free Monday lunches\nNursery workplace benefit scheme (Yellownest) \nOption to lease an electric car through Electric Car Scheme \nCelebrated Zinc anniversaries","description_format":"text","description_chars":3601,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Human Resources"],"lifecycle":[{"event":"open","at":"2026-11-04T14:33:52Z"}],"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":2,"expected_fill_days":24,"reasons":["conf:4","win:early"],"computed_at":"2026-11-06T05:58:05Z"},"pay":{"stated_usd_annual":100623,"is_top_pay":false},"html_url":"https://alion.io/job/zinc-integrations-engineer","json_url":"https://alion.io/job/zinc-integrations-engineer.json","meta":{"generated_at":"2026-11-06T13:28:30Z","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":24723,"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":172552},"rest":"https://alion.io/mcp/rest/get_company?id=172552"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fzinc-integrations-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%2Fzinc-integrations-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%2Fzinc-integrations-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/zinc-integrations-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fzinc-integrations-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3748976}},{"tool":"search_jobs","arguments":{"company":"zincwork.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3748976},"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.
