You’ll play a key role in designing and implementing solutions to non-trivial engineering problems that arise from growing product complexity, ensuring we can keep our product development fast and sustainable.\nYou’ll become a key part of our ever-growing and highly motivated product team, working closely with other engineers, designers, product and technical leadership. Your work will be focused on our cross-platform Flutter application and the surrounding cloud infrastructure built on Firebase (Google Cloud), TypeScript and C# (ASP.NET Core).\nThe work will be truly engaging and fun, and you will be able to learn a lot. We do everything in-house: from physical hardware design and embedded firmware to our app and cloud infrastructure.\nWe build and maintain iOS and Android applications with a single code base on Flutter. Our app blends sports tech with game-like training: live motion tracking, real-time audio and vibration feedback, responsive animations, and interactive practice drills. It’s a rare chance to work on software that people literally hold, wear, and play with every day.\nYour tasks\nImplement deep technical projects across the HackMotion app and its surrounding infrastructure.\n\nConduct the research and prototyping whenever we need to expand our capabilities or solve non-obvious technical puzzles.\n\nAct as a technical sounding board, consulting on technical decisions through code reviews and everyday problem-solving.\n\nChampion sound software design and testing, ensuring we can adapt to changing product requirements safely and quickly.\n\nBring your technical perspective to product and engineering planning sessions.\n\nWhat we expect\nAt least 3 years of relevant software development experience.\n\nProficiency building apps with a modern declarative UI framework (mobile experience like Flutter, React Native, SwiftUI, or Compose preferred) and enthusiasm to work with Flutter.\n\nSolid grasp of object-oriented programming concepts, architecture design, and domain modeling.\n\nExperience with designing and maintaining reliable test suites.\n\nExperience with designing and deploying databases (SQL or NoSQL) to meet application needs over time.\n\nBasic familiarity with cloud infrastructure concepts (AWS, GCP, etc.).\n\nProficiency with Git, familiarity with CI/CD systems (knowledge of Jujutsu VCS is a bonus).\n\nSharp analytical problem-solving skills.\n\nFluent English communication (both written and verbal).\n\nWhat you can expect\nSalary 4000 - 4800 EUR before taxes + company stock options (own part of the company).\n\nDevelop inspiring applications - motion capture for sports.\n\nLearn how consumer hardware products are built and gain exposure to the entire stack (from embedded C to cloud infrastructure).\n\nJoin a profitable & fast-growing tech company.\n\nFriendly and open company culture (internally we share everything related to building the company).\n\nWe work in an office & remote mix (we don’t need you at a desk for a fixed time, we need the work to be done).","description_format":"text","description_chars":3153,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":["Stock options"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Sports Wearables","Sporting Goods"],"lifecycle":[{"event":"open","at":"2026-10-16T18:23:57Z"}],"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:1","win:early"],"computed_at":"2026-10-17T00:52:48Z"},"pay":null,"html_url":"https://alion.io/job/hackmotion-senior-mobile-developer","json_url":"https://alion.io/job/hackmotion-senior-mobile-developer.json","meta":{"generated_at":"2026-10-17T00:52:48Z","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":1149,"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":678032},"rest":"https://alion.io/mcp/rest/get_company?id=678032"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhackmotion-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%2Fhackmotion-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%2Fhackmotion-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/hackmotion-senior-mobile-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhackmotion-senior-mobile-developer"}]}
