You will turn refined product work into features that are shipped, tested and observable, and improves the quality of the code you touch.\nWHAT YOU'LL BE DOING:\nCRAFT \nWrites production Swift confidently. Most new work is SwiftUI; the app still contains UIKit that is being migrated, so both are relevant. \nWorks effectively in a modular codebase. Understands why a type belongs in one module rather than another, and adds features without crossing module boundaries. \nApplies Clean Architecture and MVVM as standard, can explain the separation of concerns, and identifies where a pull request breaks it. \nWrites unit tests as part of the work rather than afterwards, and is comfortable building test doubles. Some of the team work test-first, and we want to increase that. \nUnderstands Swift concurrency sufficiently to avoid data races, and raises it when a problem exceeds their experience. \nDiagnoses production issues from crash reporting and analytics, and identifies the root cause independently. \nTreats performance, accessibility and app size as part of completing a piece of work. \nUnderstands the path their code takes after merge: CI, review, distribution and App Store submission, and the common failure points at each stage. \nUses a branching strategy consistently and writes pull requests that are straightforward to review. \nRaises design specifications that conflict with the Human Interface Guidelines rather than implementing them unchanged. \nConsiders security and dependency risk routinely, and can assess whether a third-party SDK should be added\nDELIVERY\nContributes actively to Agile ceremonies, and raises when one is no longer useful. \nHelps Product Owners refine stories into buildable work, and raises when a story is not ready. \nBreaks work into increments that each deliver value, rather than a sequence that only delivers at the end. \nDemonstrates their own work to non-technical stakeholders and explains its value in plain language. \nRaises problems early, while they are still inexpensive to fix.\nCULTURE \nUses their 10% time and shares what comes out of it. \nCross-skills beyond iOS sufficiently to work with adjacent teams. \nShares what they learn through an appropriate channel. \nDocuments solutions to a level the next person can use: diagrams, decisions and reasoning. \nListens and understands other perspectives before forming an opinion, and asks questions that draw out wider input. \nLEADERSHIP \nBrings a formed view to a discussion rather than an open question, and revises it when presented with a better argument. \nTakes responsibility for their contribution to an outcome, including when it goes wrong. \nTreats input from design, product and QA as a constraint to understand rather than an obstacle. \nWeighs team goals against their own workload when the two conflict.\nWHAT YOU'LL NEED:\nEssential Criteria:\nSeveral years writing Swift in a production app used by customers. \nSwiftUI work you have written is live in the App Store. \nExperience working in an established codebase alongside other engineers. \nYou write unit tests for your own production code as a matter of routine. \nYou have been responsible for resolving a production issue. \n Desirable:\nWorked on consumer or e-commerce apps at scale. \nExperience of a UIKit to SwiftUI migration. \nExperience of feature flagging and experimentation in production. \nKotlin, or another second platform, sufficient to collaborate with the Android team. \nCLOSING DATE: \nMonday 12th October\nLOCATION:\nPlease note this is a hybrid role and requires the successful candidate to attend at least 3 days a week in GSIQ, Solihull, UK.","description_format":"text","description_chars":3775,"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":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-09-28T20:37:30Z"}],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":2,"expected_fill_days":18,"reasons":["conf:3","velocity","win:early"],"computed_at":"2026-10-01T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/theinsidejob-mobile-engineer-ios","json_url":"https://alion.io/job/theinsidejob-mobile-engineer-ios.json","meta":{"generated_at":"2026-10-02T02:24:23Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":3214,"day_limit":5000,"remaining_today":1786,"minute_limit":60,"resets_at":"2026-10-03T00:00:00Z"}}}
