Mobile Developer (BLE || Flutter iOS Android || freelance)

Were looking for a Mobile Developer with serious BLE experience. Flutter native iOS (Swift) native Android (Kotlin) or some combination were open as long as you know how to make apps talk to devices. Youd join us on a freelance time & material basis: youre paid for the hours you actually work on real client projects. Next project in this area kicks off in January or February so were starting now to bring the right person on board in time. The first three months are about figuring out if were a good match. When things work out and that depends on the work itself the project pipeline and business timing theres a real path to our core team with a permanent contract and full benefits.

Weve 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. Were 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 youll feel at home.

If you like being told exactly what to build every morning opening Jira closing Jira and logging off at 17:01 were 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. Were 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 wont 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.

• Own the mobile side of a connected-product project: wearables smart sensors health-tech devices

• Design and implement BLE communication flows that hold up in the real world

• Debug real-world device interactions including the ones that only happen on one phone in one room

• Work side by side with firmware engineers backend designers QA and PMs

• Contribute to architecture and technical decisions not just execute someone elses

• Communicate directly with the client: you wont be hidden behind layers of management

• Use AI tools as part of your daily workflow not as a party trick

Fully 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 youre not there. Working hours are flexible: most of the team operates between 10:00 and 18:00 CET and thats 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. Youll 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.

• 90-180 PLN/h net B2B depending on your experience

• Truly flexible hours: you organize your day

• Fully remote with pet-friendly Warsaw office Gdansk cowork if you want them

• Access to our internal knowledge-sharing: tech talks experiments side projects

• When the first 3 months work out and that depends on the work the project pipeline and business timing theres 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

No sugarcoating: during the freelance period theres no paid leave or medical benefits. Those come with the permanent contract and were transparent about that upfront.

We 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 well make sure you have the support to hit the ground running. Youll 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 isnt working. If its great youll know. If something needs adjusting youll hear about it while theres still time to adjust.

Fast and to the point. The entire process is in English. All interviews are recorded for internal evaluation purposes.

1. Application with a few screening questions

2. HR call 45 min just to align on expectations

3. Technical meeting 90 min with the technical team (discussion practical live task)

4. Final decision within a few days

Once were in touch youll hear from us fast. We dont ghost and we dont drag.

intent 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 youve built that made you proud ideally something where BLE was involved.
