As a Senior Software Engineer, you'll work closely with cross-functional teams to architect, build, test, and deliver features and reliability improvements across the full stack. You'll take ownership of problems end-to-end and help evolve our developer tooling, CI/CD pipeline, and engineering standards. Enjoy benefits like stock options, paid vacation, and a dedicated hour each week to run.\nMissions\nArchitect, build, test and deliver features and reliability improvements across the full stack, from mobile apps to backend systems.\nTake ownership of problems end-to-end, from design through build, release, testing and support, and work closely with Product and Design to find the best solution.\nHelp evolve developer tooling, CI/CD pipeline and engineering standards, and support teammates on tricky technical problems.\nProfil recherché\n - We care about how well you build software, how you work within a team, and how fast you learn. Runna's stack and problems will keep changing as we grow, so we're looking for strong engineers who pick up new systems quickly and bring good judgement wherever they land, not a checklist match against today's tech- If you don't tick every box below, please apply anyway. Research shows that strong candidates can rule themselves out over a partial match even when they'd do the job well. If you're a strong full-stack engineer keen to learn, we'd rather hear from you than not, and we're happy to talk about whether a different role or level might be a better fit\n- You pick up new languages, frameworks and systems quickly, and you're comfortable working outside your current comfort zone as our roadmap evolves\n- You enjoy working closely with product, design and other engineers to find the best solution to a problem, not just the most technically interesting one\n- You're a strong full-stack engineer (frontend or backend-leaning is fine) with a track record of shipping features end-to-end\n- You care about the craft, writing readable and well-tested code, and have good judgement about when to move fast and when to slow down\n- You take the initiative and look to impact beyond your immediate team, such as improving developer experience or AI-enablement\n- Frontend: React Native, TypeScript, GraphQL\n- Tooling (continuously re-evaluated): Claude Code, Cursor, Linear with agents, Github with GHA\n- We hire for general strength, not stack familiarity - most of our engineers joined without prior experience in one or more of the above, and we'll get you fully ramped up during onboarding\n- Backend: serverless on AWS, Node.js/Python, DynamoDB, Snowflake\n- Experience with native mobile development (Swift, Kotlin, SwiftUI, watchOS) - useful given how close some of our hardest problems sit to the OS, but not a dealbreaker if you don't have it yet\n- Open-source contributions, big or small\n- Experience with infrastructure-as-code (Terraform, CDK, CloudFormation) or serverless architectures\n- A strong interest in health or fitness technology","description_format":"text","description_chars":3051,"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":["Stock options"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-07T13:10:09Z"}],"visa":[],"liveness":{"score":59,"band":"ok","label":"Likely open","p_open":1,"p_active":0.792,"p_room":0.75,"age_days":28,"expected_fill_days":39,"reasons":["conf:1","velocity","win:late"],"computed_at":"2026-10-10T05:45:15Z"},"pay":{"stated_usd_annual":126035,"is_top_pay":false},"html_url":"https://alion.io/job/runna-senior-software-engineer-full-stack","json_url":"https://alion.io/job/runna-senior-software-engineer-full-stack.json","meta":{"generated_at":"2026-10-11T00:09:39Z","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","counted_by":"address","units_charged":1,"used_today":91,"day_limit":5000,"remaining_today":4909,"minute_limit":60,"resets_at":"2026-10-12T00:00:00Z"}},"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":1770154},"rest":"https://alion.io/mcp/rest/get_company?id=1770154"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Frunna-senior-software-engineer-full-stack"},{"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%2Frunna-senior-software-engineer-full-stack"},{"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%2Frunna-senior-software-engineer-full-stack"},{"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/runna-senior-software-engineer-full-stack\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Frunna-senior-software-engineer-full-stack"}]}
