It's where they complete their consultation, manage their treatment and subscriptions, book and track tests, message their clinician and health coach, and follow their programme day to day. When it's fast, clear and reliable, patients stay on track with their health. When it isn't, they drop off.\nYou'll work in a cross-functional squad with product, design and backend engineers. You'll own features from idea to App Store and Google Play, shape the app's architecture, and raise the bar on quality across the mobile team. This is a Level 5 (Senior Engineer) role in our engineering framework: you'll deliver large features across a whole product area, think holistically about the app, and collaborate with and mentor the engineers around you.\nYou'll be working with special category health data, so privacy, security and accessibility are part of the job, not an afterthought.\n\nYou will:\nDesign, build and ship features in the Numan app, owning them from technical scoping through release and post-launch monitoring.\n\nWrite production-quality native code in Swift and SwiftUI (iOS) or Kotlin and Jetpack Compose (Android), with strong test coverage.\n\nShape and evolve the app's architecture: modularisation, state management, networking, offline behaviour and how we share patterns across platforms.\n\nWork with product and design to turn patient problems into simple, accessible experiences, and push back when a simpler approach would serve patients better.\n\nPartner with backend engineers on API design so the app gets the data it needs, efficiently and securely.\n\nOwn app quality: crash rates, performance, startup time and accessibility (WCAG). Use monitoring and analytics to find and fix problems before patients notice them.\n\nImprove our mobile delivery pipeline: CI/CD, automated testing, feature flags, phased rollouts and App Store / Google Play release management.\n\nProtect patient data. Build with secure storage, authentication and privacy in mind, in line with UK GDPR and healthcare requirements.\n\nGive thorough, constructive code reviews and write clear documentation, RFCs and PR descriptions.\n\nMentor other engineers, share knowledge across the mobile team, and help set standards and working practices.\n\nInterview candidates and help us grow the team.\n\nUse AI coding assistants thoughtfully to move faster without lowering the bar on quality.\n\nYou'll have:\n5+ years building mobile apps professionally, with at least one consumer app you've helped ship and scale on the App Store or Google Play.\n\nDeep expertise in native development on at least one platform: Swift and SwiftUI (iOS) or Kotlin and Jetpack Compose (Android). Working knowledge of the other platform is a plus.\n\nA strong grasp of mobile architecture (for example MVVM, unidirectional data flow, dependency injection, modularisation) and the judgement to know when to keep things simple.\n\nA testing mindset: unit, UI and snapshot testing, and experience building testable code.\n\nExperience with CI/CD for mobile (for example Fastlane, Bitrise, GitHub Actions or Xcode Cloud) and managing releases end to end.\n\nExperience integrating with REST or GraphQL APIs, handling auth, caching and error states well.\n\nA track record of owning large features or product areas and improving the engineering practices of the team around you.\n\nExperience mentoring engineers and giving useful code reviews.\n\nClear communication with engineers and non-engineers alike, and comfort working closely with product and design.\n\nCare for patients and an understanding of why privacy and accessibility matter in health products.\n\nExperience working in an agile team, delivering in sprints and working effectively with product and design to deliver real value to customers often.","description_format":"text","description_chars":3886,"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":"Lithuania","iso":"LT","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Telemedicine & Virtual Care"],"lifecycle":[{"event":"open","at":"2026-10-28T16:50:35Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":24,"reasons":["conf:0","win:early"],"computed_at":"2026-10-29T05:49:05Z"},"pay":null,"html_url":"https://alion.io/job/numan-senior-mobile-developer","json_url":"https://alion.io/job/numan-senior-mobile-developer.json","meta":{"generated_at":"2026-10-30T05:32:19Z","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":7702,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-31T00:00:00Z"}},"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":51644},"rest":"https://alion.io/mcp/rest/get_company?id=51644"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fnuman-senior-mobile-developer"},{"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%2Fnuman-senior-mobile-developer"},{"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%2Fnuman-senior-mobile-developer"},{"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/numan-senior-mobile-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fnuman-senior-mobile-developer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3408075}},{"tool":"search_jobs","arguments":{"company":"numan.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3408075},"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.
