Responsibilities
- 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
Requirements
- 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
Benefits
- 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
Additional Information
- 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.
- 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. 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 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.
