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

In short

We're looking for a Mobile Developer with serious BLE experience. 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.

Why intent?

We'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.

Who this role is NOT for

If 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.

What you'll do

• 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 else's
• Communicate directly with the client: you won't be hidden behind layers of management
• Use AI tools as part of your daily workflow, not as a party trick

How we work

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 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.

What you'll get

• 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, 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
• No 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.

Your first weeks

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 to jump in early, we'll be honest about it.
