That’s millions helping organisations like Age UK, the RSPCA, British Heart Foundation and Great Ormond Street Hospital Charity deliver life-saving work.\nAnd the best part? We’re only just getting started. Omaze is building a business and culture committed to growth and creating significant social impact on a global scale.\nWhy You’ll Love Working at Omaze\nGrowth: Omaze is one of the fastest-growing companies in the world.\n\nImpact: Join a team of world changers dedicated to creating a ripple effect of good.\n\nPioneering: Be part of something no one has done before.\n\nCulture: We work hard, grow together, and spread joy along the way.\n\nWhat you'll be doing\nAs a Senior Mobile Engineer at Omaze, you take genuine ownership of the mobile experience our customers rely on and you care deeply about getting it right. React Native and Expo are your primary tools, and you're experienced enough with both to know their strengths, their limits, and when to reach beyond them. That's where your native knowledge comes in: whether it's Swift, Kotlin, or both, you're comfortable dropping into native code when the situation calls for it when it comes to performance, platform APIs, or something Expo just can't do out of the box. At Omaze, we are aiming for our app to not just be a utility but a premium experience.\nWhat You'll Be Doing\nOwn the design, implementation, and testing of features across our TypeScript, React Native and Expo codebase, producing code that's performant, maintainable, and delivers a genuinely great user experience on both iOS and Android.\n\nWork closely with product and UX from the earliest stages of a feature, contributing to interaction and technical design decisions before they're hard to change.\n\nOwn the quality of what you ship end-to-end: writing well-tested components, holding a high bar in code review, and taking responsibility for production behaviour.\n\nContribute to release pipeline and EAS build and deployment workflows to help the team ship frequently, safely, and with confidence.\n\nUphold and actively contribute to mobile engineering standards and best practices, patterns, performance budgets, and platform-specific conventions that keep the codebase healthy as it grows.\n\nUse AI-assisted and agentic coding tools as a natural part of your workflow, applying the same rigour and judgement to AI-generated code as you would to anything hand-written.\n\nAbout You\nPassionate about mobile craft: you notice when an animation is 2ms off, when a transition doesn't feel quite right, or when a scroll list isn't as smooth as it should be and you do something about it.\n\nYou understand that for a premium experience, performance is the product. You think about frame rates, responsiveness, and perceived speed not as nice-to-haves but as core quality requirements, and you have the tools and instincts to measure, diagnose, and raise the bar.\n\nSignificant experience as a mobile engineer, with strong hands-on expertise in React Native and Expo, including EAS build and submission workflows.\n\nExperience working across iOS and Android within a shared React Native codebase, with a solid understanding of platform-specific behaviour and constraints.\n\nNative mobile experience in Swift (iOS) and/or Kotlin (Android) is desirable. You can read, write, and debug native code.\n\nStrong understanding of mobile performance. You know how to diagnose and fix issues across JS thread, native thread, and render pipeline.\n\nExperience with automated testing for mobile unit, integration, and end-to-end (e.g. Jest, Maestro, Appium).\n\nFamiliar with App Store and Google Play submission, review processes, and release management.\n\nA collaborative, clear communicator who works well with product, UX, and backend engineers. You can translate mobile constraints into language the whole team understands.\n\nWhat’s In It For You\nGenerous stock options scheme\n\n25 days annual leave PLUS Bank Holidays\n\nPrivate medical and dental insurance\n\n9% employer pension contributions, when you contribute at least 2%\n\nA generous personal learning and development budget each year to use on training courses, conferences and professional memberships\n\nEnhanced family leave policies\n\nLife assurance of 4x your salary\n\nDEI Statement\nWe actively seek out diversity of thought and experience to drive innovation. We welcome all backgrounds, identities, and perspectives and work hard to ensure that every Omaze employee can bring their authentic self to work at all times.","description_format":"text","description_chars":4862,"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","Dental insurance","Parental leave","Stock options"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Nonprofits & Foundations"],"lifecycle":[{"event":"open","at":"2026-07-23T07:45:34Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"evidence":"Licensed UK visa sponsor (Senior or Specialist Worker, Skilled Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Global Business Mobility: Senior or Specialist Worker; Skilled Worker","cap_exempt":false,"checked_at":"2026-10-17T06:21:15+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":22,"band":"cold","label":"Long shot","p_open":1,"p_active":0.599,"p_room":0.36,"age_days":85,"expected_fill_days":49,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/omaze-senior-mobile-engineer","json_url":"https://alion.io/job/omaze-senior-mobile-engineer.json","meta":{"generated_at":"2026-10-17T06:48:31Z","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":9353,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":5798},"rest":"https://alion.io/mcp/rest/get_company?id=5798"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fomaze-senior-mobile-engineer"},{"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%2Fomaze-senior-mobile-engineer"},{"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%2Fomaze-senior-mobile-engineer"},{"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/omaze-senior-mobile-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fomaze-senior-mobile-engineer"}]}
