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 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.
Recruitment process
Fast and to the point. The entire process is in English. All interviews are recorded for internal evaluation purposes.
Application with a few screening questions
HR call, ~45 min, just to align on expectations
Technical meeting, ~90 min, with the technical team (discussion + practical live task)
Final decision within a few days
Once we're in touch, you'll hear from us fast. We don't ghost and we don't drag.
One more thing
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 you've built that made you proud, ideally something where BLE was involved.
Requirements
What we're looking for
5+ years as a Mobile Developer
Strong hands-on BLE experience (not "I read about it once")
Proficiency in Flutter AND at least one native platform (iOS/Swift or Android/Kotlin)
Experience working with connected products: device pairing, real-time data streaming
Comfort working in short sprints (1-2 weeks) in a fast-moving environment
Strong communication skills with teammates and clients
English at B2+, written and spoken, because our clients are mostly US-based
Focus on product quality and user experience, not just "ship it and move on"
Independence and ownership: you flag risks early and you don't wait to be told
Nice to have
Direct experience collaborating with firmware teams
Medical devices or other regulated environments
Testing strategies for BLE flows
OTA updates or provisioning flows
Genuine curiosity about the devices you build for, not just the code behind them
