This is not traditional QA: you'll write the code, tools, and frameworks that let our engineers ship with confidence.\nYou'll work closely with the Cloud team and engineers across Radiant, and shape how the whole engineering organisation tests.\nKey Responsibilities\nBuild test infrastructure in Go.\n\nValidate gRPC and REST APIs, and build end-to-end tests.\n\nSet up test management and quality dashboards.\n\nIntegrate testing into CI/CD.\n\nShape testing practices across the engineering team.\n\nYour Profile\n6-7+ years in software engineering or SDET roles.\n\nStrong Go.\n\nExperience testing gRPC and REST APIs.\n\nExperience building end-to-end test frameworks from scratch.\n\nExperience with test management tools such as TestRail.\n\nWhat You Bring\nBuilder's mindset: Happy to start from a blank page and set the standard.\n\nEngineering quality: Write clean, tested, maintainable code, and review others' work with care.\n\nOwnership: Take features from design through production, and stay accountable for how they run.\n\nPragmatism: Ship what matters, simply, and improve it from real-world feedback.\n\nCollaboration: Work openly with product, infrastructure, SRE and customers, and share what you learn.\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: Talent screen → Hiring Manager → Technical interview (two engineers) → Whiteboard Session → Final.\nCompany Overview:\nRadiant is redefining how AI infrastructure is built.\nWe design and operate AI-native cloud platforms engineered for sovereignty, performance, and scale. 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.","description_format":"text","description_chars":3777,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Annual leave","Health insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["MLOps","AI Compute & Inference"],"lifecycle":[{"event":"open","at":"2026-11-09T22:19:01Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":0,"expected_fill_days":49,"reasons":["conf:3","velocity","win:early"],"computed_at":"2026-11-10T06:52:35Z"},"pay":null,"html_url":"https://alion.io/job/radiant-founding-sdet","json_url":"https://alion.io/job/radiant-founding-sdet.json","meta":{"generated_at":"2026-11-10T07:19:09Z","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":17040,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-11T00:00:00Z"}},"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-founding-sdet"},{"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-founding-sdet"},{"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-founding-sdet"},{"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-founding-sdet\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fradiant-founding-sdet"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3988037}},{"tool":"search_jobs","arguments":{"company":"radiant.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3988037},"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.
