You will be responsible for wrapping and extending open-source native mapping engines, integrating our custom routing APIs, and exposing a clean, robust, and developer-friendly API surface for both Android and iOS platforms.\nYou will work directly with the founders to turn our navigation logic into a reusable, high-performance SDK product.\nResponsibilities\nSDK Architecture: Design and implement a unified navigation SDK architecture for Android (Kotlin) and iOS (Swift) that wraps underlying native mapping libraries. \nCore Navigation Logic: Implement complex logic for turn-by-turn navigation, including route snapping, off-route detection, rerouting, and ETA calculation. \nAPI Design: Craft intuitive, idiomatic, and thread-safe APIs for client developers. You are building tools for other engineers, so Developer Experience (DX) is paramount. \nPerformance Optimization: Optimize for battery usage, memory management (tile caching), and CPU efficiency during active navigation sessions. \nSensor Fusion: Work with raw GPS, accelerometer, and gyroscope data to improve location accuracy and handle \"tunnel\" or weak-signal scenarios. \nRelease Engineering: Manage the CI/CD pipeline for SDK distribution (Maven Central, CocoaPods, Swift Package Manager) and versioning. \nRequirements\n10+ Years of Engineering Experience: Deep expertise in mobile development lifecycles. \nDual Native Proficiency: High proficiency in both Kotlin (Android) and Swift (iOS). You must be comfortable context-switching between platforms. \nSDK/Library Development: Proven experience building and maintaining SDKs or shared libraries consumed by third-party applications. You understand semantic versioning, backward compatibility, and ABI stability. \nSystem Design: Experience designing clean interfaces (Facade pattern, Delegate pattern, Observer pattern) to hide complex internal logic. \nBackground Execution: Deep understanding of Android Foreground Services and iOS Background Modes (Location Updates, Audio) to ensure navigation survives when the app is minimized. \nSpecialized Skills (Highly Preferred):\nGIS & Mapping: Experience with the internals of major Mapping or Navigation SDKs. Understanding of Vector Tiles (OpenGL/Metal rendering), GeoJSON, and coordinate projection systems (Mercator vs. WGS84). \nGeometry Math: Familiarity with computational geometry (calculating bearings, distances, polygon intersections, and line snapping). \nKotlin Multiplatform (KMP): Experience or interest in migrating shared business logic to KMP to reduce code duplication between Android and iOS. \nBinary Compatibility: Understanding of ProGuard/R8 rules (Android) and Module interfaces (iOS) to prevent symbol conflicts.","description_format":"text","description_chars":2952,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-09-10T23:42:17Z"},{"event":"close","at":"2026-11-08T01:46:58Z"}],"visa":[],"liveness":null,"pay":null,"html_url":"https://alion.io/job/flatgigs-principal-mobile-sdk-engineer-navigation","json_url":"https://alion.io/job/flatgigs-principal-mobile-sdk-engineer-navigation.json","meta":{"generated_at":"2026-11-08T03:45:56Z","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":8125,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-09T00:00:00Z"}},"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":672990},"rest":"https://alion.io/mcp/rest/get_company?id=672990"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fflatgigs-principal-mobile-sdk-engineer-navigation"},{"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%2Fflatgigs-principal-mobile-sdk-engineer-navigation"},{"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%2Fflatgigs-principal-mobile-sdk-engineer-navigation"},{"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/flatgigs-principal-mobile-sdk-engineer-navigation\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fflatgigs-principal-mobile-sdk-engineer-navigation"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":682513}},{"tool":"search_jobs","arguments":{"company":"flatgigs.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":682513},"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.
