Our infrastructure powers GPU-native workloads, multi-tenant control planes, and high-performance AI systems designed for the most demanding environments.\nWe are not building a generic cloud. We are building purpose-built AI infrastructure - from powered land, to compute, to software.\nAs we scale, we're building this organisation from the ground up. We're looking for people who'd rather build the playbook than inherit one - who are comfortable doing the work themselves as well as directing others, and who can adapt as fast as our strategy does. This is a startup model: attitude and adaptability matter more to us than years of experience or the size of the team you've previously managed.\nWhat You'll Do\nAs Head of Engineering, you will lead Radiant's engineering organisation and be accountable for its execution, technical quality, reliability, and scalability.\nYou'll lead software engineering, platform security engineering, and architecture: an organisation of 30-35 engineers today, growing to 150 to 200+ as Radiant expands internationally. You'll partner closely with Product, the Customer team, Infrastructure, SRE, Operations, the PMO, and the wider technology leadership team.\nThis is a senior leadership role focused on building a high-performing engineering organisation capable of delivering and operating complex AI infrastructure at scale. You'll stay close to the work through design review.\nKey Responsibilities\nHire and scale the engineering organisation, building a strong leadership layer across Engineering Managers, Principal Engineers, and senior technical leaders.\n\nOwn engineering hiring, performance, leadership development, succession planning, and organisational health.\n\nDesign and evolve the engineering organisation as the company scales across teams, sites, and regions.\n\nOwn the engineering strategy, operating model, and execution in alignment with company and product objectives.\n\nTranslate business priorities into clear technical plans, sequencing, investment decisions, and delivery commitments.\n\nEstablish clear ownership, decision-making, and accountability across engineering teams.\n\nDrive predictable, high-quality delivery, identifying risk early and intervening where execution drifts.\n\nEnsure systems are designed and delivered to be production-ready, reliable, observable, maintainable, and supportable.\n\nStrengthen collaboration with infrastructure, SRE, and operations, including effective handover and incident learning.\n\nSet and uphold standards across architecture, engineering quality, security, scalability, and operational maturity.\n\nOwn the roadmap jointly with Product: Product owns what is built, and you own how and when.\n\nAct as the senior escalation point for critical technical, architectural, and delivery decisions, brokering decisions between peers and escalating to the CTO when needed.\n\nImprove engineering maturity and processes while avoiding unnecessary bureaucracy or loss of delivery momentum.\n\nRepresent engineering in executive and partner discussions, and join customer escalation reviews with the Customer team.\n\nYour Profile\nSignificant experience leading and scaling engineering organisations of 20+ engineers through multiple stages of growth.\n\nExperience managing managers, with a strong track record of hiring and developing Engineering Managers, senior engineers, and technical leaders.\n\nProven experience evolving a smaller engineering group into multiple teams with clear ownership, leadership, and consistent delivery.\n\nExperience designing organisational structures, team boundaries, and operating models for increasing scale and complexity.\n\nDemonstrated success improving delivery predictability, engineering quality, throughput, and organisational effectiveness.\n\nStrong technical background across modern software engineering, distributed systems, cloud platforms, or infrastructure-heavy products.\n\nExperience owning production systems where reliability, observability, scalability, and operational readiness are critical.\n\nComfortable working closely with Product, Infrastructure, SRE, Operations, and Commercial teams.\n\nExperience operating across multiple teams, locations, or time zones.\n\nAble to communicate technical risk, trade-offs, and opportunity clearly at executive level.\n\nExperience with cloud or infrastructure platforms, scaled SaaS, AI/ML platforms, or infrastructure-heavy technology businesses is strongly preferred.\n\nHow You Work\nYou move fast and correct course quickly.\n\nYou challenge openly, then commit.\n\nYou address underperformance within weeks, with clear coaching and firm deadlines.\n\nYou keep process light and standards high.\n\nWhat You Bring\nEngineering leadership: You build strong teams, strong leaders, and clear accountability.\n\nExecution: You create predictability and drive complex programmes through to completion.\n\nTechnical judgement: You can guide architecture and challenge senior engineers without becoming a bottleneck.\n\nSystems thinking: You understand organisations, platforms, and operating models as interconnected systems.\n\nOperational mindset: You expect engineering output to be reliable, supportable, and production-ready.\n\nOrganisational design: You know when structures, processes, or ownership models need to evolve.\n\nCalm leadership: You remain decisive under pressure and make clear trade-offs when required.\n\nOwnership: You take responsibility for engineering outcomes, organisational health, and long-term capability.\n\nQualities we look for:\nSet the standard: Every single day, you spot opportunities to constructively shake things up\n\nInspire the change: There's no blueprint for the future. You'll embrace challenges and change\n\nYou're real and you're true to yourself: We cherish and celebrate diversity so you'll feel right at home whoever you are and whoever you're talking to, you treat everyone the same.\n\nWhy should you join us?\nWhat sets us apart is our blend of modern technology, competitive benefits, and an open, welcoming work culture that enables our people to thrive.\nHere are just some of the great things you can expect from us:\n25 days of annual leave\n\nA culture that emphasises results over hierarchy, process & ego: we place great emphasis on the quality, ingenuity and creativity of work.\n\nOpen communication, regular feedback: we value smooth collaboration, direct and actionable feedback, and believe that leading with empathy and a growth mindset makes us better together.\n\nLearning Time: we all have dedicated learning time to focus on new skills, projects or interests that lay outside of your day-to-day job.\n\nHealth & Wellbeing: we want everyone to feel healthy and happy, so we offer private medical insurance via Bupa.\n\nCycle to Work Scheme: we're committed to building a sustainable business, so we encourage cycling to work.\n\nGympass subscription to a variety of gyms and wellbeing apps\n\nParticipation in the company shares program\n\nEnhanced parental pay & leave\n\nOur process: a conversation with our Talent team, then interviews with our CTO and leadership team.","description_format":"text","description_chars":7224,"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","Health insurance"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["MLOps","AI Compute & Inference"],"lifecycle":[{"event":"open","at":"2026-11-07T13:59:03Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":3,"expected_fill_days":49,"reasons":["conf:0","velocity","win:early"],"computed_at":"2026-11-11T05:49:22Z"},"pay":null,"html_url":"https://alion.io/job/radiant-head-of-engineering","json_url":"https://alion.io/job/radiant-head-of-engineering.json","meta":{"generated_at":"2026-11-11T09:43:20Z","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":16293,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-12T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":8822},"rest":"https://alion.io/mcp/rest/get_company?id=8822"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fradiant-head-of-engineering"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Fradiant-head-of-engineering"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fradiant-head-of-engineering"},{"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/radiant-head-of-engineering\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fradiant-head-of-engineering"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3919425}},{"tool":"search_jobs","arguments":{"company":"radiant.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3919425},"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);
