Flutter, native iOS (Swift), native Android (Kotlin), or some combination, we're open as long as you know how to make apps talk to devices. You'd join us on a freelance, time & material basis: you're paid for the hours you actually work on real client projects. Next project in this area kicks off in January or February, so we're starting now to bring the right person on board in time. The first three months are about figuring out if we're a good match. When things work out, and that depends on the work itself, the project pipeline, and business timing, there's a real path to our core team with a permanent contract and full benefits.\nWhy intent?\nWe've been designing and co-creating connected devices since 2008. Wearables, smart audio, health-tech hardware for clients like Oura and BOSE, backed by investors like a16z and Founders Fund. We're 60+ people, fully remote, and AI-native since before LinkedIn influencers discovered the term. Most of our projects are long-term partnerships, so we care about building solid relationships, with clients and inside the team. If you enjoy debugging edge cases in device communication and working with firmware and backend engineers on real products that ship, you'll feel at home.\nWho this role is NOT for\nIf you like being told exactly what to build every morning, opening Jira, closing Jira, and logging off at 17:01, we're probably not your people. We look for engineers who ask \"why\" before \"how\", challenge assumptions, and dig into the weird BLE bug nobody else wants to touch. We're AI-native and we expect you to treat AI as a daily multiplier, not a gimmick. What we expect: ownership of the mobile side of the project, straight talk with clients (you won't be hidden behind layers of management), and the kind of curiosity that makes you actually care about the device on the other end of your Bluetooth connection.\nWhat you'll do\nOwn the mobile side of a connected-product project: wearables, smart sensors, health-tech devices\n\nDesign and implement BLE communication flows that hold up in the real world\n\nDebug real-world device interactions, including the ones that only happen on one phone in one room\n\nWork side by side with firmware engineers, backend, designers, QA, and PMs\n\nContribute to architecture and technical decisions, not just execute someone else's\n\nCommunicate directly with the client: you won't be hidden behind layers of management\n\nUse AI tools as part of your daily workflow, not as a party trick\n\nHow we work\nFully remote. We have a pet-friendly office in Warsaw and a coworking space in Gdansk if walls and coffee machines motivate you, but nobody will ask why you're not there. Working hours are flexible: most of the team operates between 10:00 and 18:00 CET, and that's when most meetings happen. Evening calls with US-based clients (up to ~20:00) are part of the rhythm, sometimes a couple of times a week, always planned ahead. You'll be part of the Mobile chapter for knowledge-sharing, and at the same time on a cross-functional project squad led by a PM for day-to-day delivery.\nWhat you'll get\n90-180 PLN/h net B2B, depending on your experience\n\nTruly flexible hours: you organize your day\n\nFully remote, with pet-friendly Warsaw office + Gdansk cowork if you want them\n\nAccess to our internal knowledge-sharing: tech talks, experiments, side projects\n\nWhen the first 3 months work out, and that depends on the work, the project pipeline, and business timing, there's a real path to a permanent contract with a fixed monthly salary, 26 days paid leave, 10 sick days, Saltus medical care, and a training budget\n\nNo sugarcoating: during the freelance period there's no paid leave or medical benefits. Those come with the permanent contract, and we're transparent about that upfront.\nYour first weeks\nWe aim to give you space to ramp up before jumping into live project work, but this is a real company with real deadlines: if the project needs you sooner, we'll make sure you have the support to hit the ground running. You'll get paired with a technical buddy and tackle progressively bigger tasks, so we can both see how the collaboration feels. Feedback comes early and often, no one waits three months to tell you something isn't working. If it's great, you'll know. If something needs adjusting, you'll hear about it while there's still time to adjust.\nRecruitment process\nFast and to the point. The entire process is in English. All interviews are recorded for internal evaluation purposes.\nApplication with a few screening questions\n\nHR call, ~45 min, just to align on expectations\n\nTechnical meeting, ~90 min, with the technical team (discussion + practical live task)\n\nFinal decision within a few days\n\nOnce we're in touch, you'll hear from us fast. We don't ghost and we don't drag.\nOne more thing\nintent is an equal opportunity employer. We care about what you can do, not where you come from. Send us your CV and a few words about why this caught your eye. Bonus points if you share something you've built that made you proud, ideally something where BLE was involved.\nRequirements\nWhat we're looking for\n5+ years as a Mobile Developer\n\nStrong hands-on BLE experience (not \"I read about it once\")\n\nProficiency in Flutter AND at least one native platform (iOS/Swift or Android/Kotlin)\n\nExperience working with connected products: device pairing, real-time data streaming\n\nComfort working in short sprints (1-2 weeks) in a fast-moving environment\n\nStrong communication skills with teammates and clients\n\nEnglish at B2+, written and spoken, because our clients are mostly US-based\n\nFocus on product quality and user experience, not just \"ship it and move on\"\n\nIndependence and ownership: you flag risks early and you don't wait to be told\n\nNice to have\nDirect experience collaborating with firmware teams\n\nMedical devices or other regulated environments\n\nTesting strategies for BLE flows\n\nOTA updates or provisioning flows\n\nGenuine curiosity about the devices you build for, not just the code behind them","description_format":"text","description_chars":6082,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"Upper-Intermediate (B2)","optional":false}]},"benefits":[],"hiring_locations":[{"name":"Poland","iso":"PL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["IoT Platforms & Solutions","Mobile App Development Services"],"lifecycle":[{"event":"open","at":"2025-03-12T12:16:27Z"},{"event":"close","at":"2026-08-13T11:20:38Z"},{"event":"reopen","at":"2026-08-30T09:58:52Z"}],"visa":[],"liveness":{"score":35,"band":"fade","label":"Fading","p_open":1,"p_active":0.805,"p_room":0.44,"age_days":582,"expected_fill_days":563,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-16T05:45:00Z"},"pay":{"stated_usd_annual":92112,"is_top_pay":false},"html_url":"https://alion.io/job/intent-mobile-developer-ble-flutter-ios-android-freelance","json_url":"https://alion.io/job/intent-mobile-developer-ble-flutter-ios-android-freelance.json","meta":{"generated_at":"2026-10-16T16:24:26Z","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":891,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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":1801},"rest":"https://alion.io/mcp/rest/get_company?id=1801"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fintent-mobile-developer-ble-flutter-ios-android-freelance"},{"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%2Fintent-mobile-developer-ble-flutter-ios-android-freelance"},{"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%2Fintent-mobile-developer-ble-flutter-ios-android-freelance"},{"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/intent-mobile-developer-ble-flutter-ios-android-freelance\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fintent-mobile-developer-ble-flutter-ios-android-freelance"}]}
