Our platform allows users to quickly and safely diagnose possible conditions, get treatment and support them afterwards to live a higher quality life. To do this, we are building an all-in-one healthcare platform which brings together world-leading medical expertise and technical excellence.\nThe Opportunity\nWe're looking for a Senior Mobile Engineer to help build and scale VOY's mobile experience - a core part of how users engage with their health, access care, and build long-term healthy habits.\nThis role goes beyond shipping screens. You'll take real ownership of mobile experiences used by thousands of patients, working end to end from understanding user problems through delivery, iteration, and measurement. You'll be joining a fast-growing product area with high visibility and a meaningful impact on our mission to become the healthcare partner people trust for life.\nOur mobile stack is built on React Native.\nAbout the Mobile Platform\nThis is a Mobile Platform role focused on the engineering foundations that enable high-quality mobile features at scale. You'll help build and maintain reusable components, architecture, and tooling that other engineers can rely on - so product teams can ship faster without sacrificing reliability, performance, or user experience.\nWorking closely with product, design, and data, you'll identify platform bottlenecks, contribute to pragmatic standards, and help create the guardrails and infrastructure that improve developer velocity and consistency across the mobile app.\nResponsibilities\nIdentify engineering pain points across the mobile codebase and contribute well-scoped, high-impact solutions to the platform roadmap\n\nDefine and uphold React Native engineering standards covering code quality, TypeScript conventions, component architecture, and testing strategy\n\nBuild and maintain the shared primitives other mobile engineers depend on: navigation, state management, networking, UI foundations, and error handling patterns\n\nPartner with product engineering squads to unblock delivery through reference implementations, shared modules, and clear migration paths\n\nContribute to and help improve the mobile CI/CD pipeline, release workflows, and build tooling to reduce friction and increase release confidence\n\nSupport the mobile observability strategy: event schemas, analytics instrumentation, crash alerting, and production dashboards that give teams actionable signal\n\nShape API contracts and backend integration patterns in partnership with platform and backend engineers\n\nContribute to technical planning for the mobile roadmap, providing input on sequencing, trade-offs, and long-term maintainability\n\nWhat You'll Do\nIdentify and resolve platform bottlenecks that slow down feature teams, from slow builds and flaky tests to inconsistent patterns and missing abstractions\n\nBuild and document reusable React Native components and modules with clean APIs that other engineers can rely on without needing deep platform knowledge\n\nProfile and optimise app performance: reduce unnecessary re-renders, cut bundle size, and improve startup and interaction latency\n\nImplement and evolve the mobile testing strategy across unit, integration, and end-to-end layers\n\nUse feature flags, analytics instrumentation, and dashboards to validate platform changes and support safe rollouts\n\nReview code across the mobile codebase, providing feedback that raises the bar on quality and consistency over time\n\nKeep the app secure through safe storage practices, secure data handling, and proactive thinking about attack surface\n\nWho You Are\nA senior engineer with a strong foundation in TypeScript and React, coming from either a React Native or frontend background. You don't need deep native mobile experience on day one, but you're excited to go deep on the mobile platform\n\nSomeone who thinks in systems: you see the patterns across a codebase and want to fix the root cause, not just the symptom\n\nComfortable writing documentation and building tools that help other engineers move faster without needing to ask you every time\n\nExperienced working cross-functionally with product, design, and backend teams, able to align on technical direction without ego\n\nPragmatic about trade-offs: you know when to invest in a robust abstraction and when to ship something simple that solves the immediate problem\n\nData-informed: you use production metrics, crash rates, and analytics to prioritise platform work and demonstrate impact\n\nA clear communicator who can translate platform complexity into plain language for engineers and non-engineers alike\n\nComfortable in a fast-moving scale-up environment where the roadmap shifts and the best engineers help shape it rather than just execute it\n\nPlease note this is a hybrid role with a requirement of 3 days per week in office.","description_format":"text","description_chars":4972,"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":[],"hiring_locations":[{"name":"Bulgaria","iso":"BG","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Medical Laboratories","Consumer Health Apps"],"lifecycle":[{"event":"open","at":"2026-10-08T23:53:18Z"}],"visa":[],"liveness":{"score":58,"band":"ok","label":"Likely open","p_open":1,"p_active":0.767,"p_room":0.75,"age_days":21,"expected_fill_days":22,"reasons":["conf:0","velocity","win:late"],"computed_at":"2026-10-12T06:55:09Z"},"pay":null,"html_url":"https://alion.io/job/joinvoy-senior-mobile-engineer-platform","json_url":"https://alion.io/job/joinvoy-senior-mobile-engineer-platform.json","meta":{"generated_at":"2026-10-12T15:06:14Z","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":23855,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-13T00:00:00Z"}},"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":1985094},"rest":"https://alion.io/mcp/rest/get_company?id=1985094"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fjoinvoy-senior-mobile-engineer-platform"},{"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%2Fjoinvoy-senior-mobile-engineer-platform"},{"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%2Fjoinvoy-senior-mobile-engineer-platform"},{"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/joinvoy-senior-mobile-engineer-platform\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fjoinvoy-senior-mobile-engineer-platform"}]}
