Building customer-facing AI agents that drive our platforms and creating omnichannel communication experiences that puts agentic conversations in the hands of consumers.\nYou'll work across the full stack, from backend services and agent orchestration logic to the interfaces customers experience. You’ll play a hands-on role in defining how we architect and scale our platform using cloud technologies and you'll be working close to the cutting edge of agentic AI, designing agents that reason, take action, and handle complex, multi-step interactions.\nWhat You'll Be Doing:\nDesign, build, and iterate on customer-facing AI agents using Python and Node.js, including orchestration, tool use, memory, and conversation logic.\nContribute to backend services using NestJS, and PostgreSQL, and Vector databases with a focus on reliability, maintainability, and scale.\nHelp develop our omnichannel platform that enables seamless conversations across multiple communication channels (web, messaging, voice, and beyond).\nCollaborate closely with product, design, and data teams to shape what agents do and how they work.\nDefine technical patterns and best practices as we scale our agentic systems globally.\nParticipate in code reviews and contribute to a culture of thoughtful, high-quality engineering.\nWhat We're Looking For:\nStrong professional experience with TypeScript across the stack. Node.js on the backend, React on the frontend.\nSolid understanding of backend architecture: API design, service patterns, and database modelling with PostgreSQL.\nExperience building or working closely with LLM-powered or agentic systems using Python. Prompt engineering, tool use, RAG, agent orchestration frameworks, or similar.\nProficiency with AI-assisted development tools (e.g. GitHub Copilot, Cursor, Claude Code).\n5+ years experience delivering software products at scale.\nA product-focused mindset, you think about users and outcomes, not just code.\nStrong communication skills, you can articulate technical decisions clearly to engineers and non-engineers alike.\nNice to have:\nExperience with agent frameworks such as LangChain, LangGraph, AgentCore or similar.\nFamiliarity with streaming, real-time, or event-driven architectures.\nBackground in automotive, dealership tech, or B2B SaaS.","description_format":"text","description_chars":2383,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Automotive Software"],"lifecycle":[{"event":"open","at":"2026-08-19T13:17:49Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"evidence":"Licensed UK visa sponsor (Skilled Worker, Senior or Specialist Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Skilled Worker; Global Business Mobility: Senior or Specialist Worker","cap_exempt":false,"checked_at":"2026-10-20T06:21:30+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":22,"band":"cold","label":"Long shot","p_open":1,"p_active":0.508,"p_room":0.44,"age_days":62,"expected_fill_days":52,"reasons":["conf:3","stale_co","velocity","win:tail","crowd:"],"computed_at":"2026-10-21T05:46:15Z"},"pay":null,"html_url":"https://alion.io/job/keyloop-senior-software-engineer","json_url":"https://alion.io/job/keyloop-senior-software-engineer.json","meta":{"generated_at":"2026-10-21T06:09:47Z","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":8956,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"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":7846},"rest":"https://alion.io/mcp/rest/get_company?id=7846"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fkeyloop-senior-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%2Fkeyloop-senior-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%2Fkeyloop-senior-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/keyloop-senior-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fkeyloop-senior-software-engineer"}]}
