If you're a Senior Android Developer who knows BLE inside out and isn't afraid of code that talks to physical things, we want to talk. You'd join us on a freelance, time & material basis: you're paid for the hours you actually work on real client projects. 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.
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. We use AI every day, in actual work, not just in company decks. If your Kotlin has ever made a physical device do something it couldn't do before, you already get why we love what we do.
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 occasionally break things because they were trying something new. We're AI-native and we expect you to treat AI as a daily multiplier, not a gimmick. What we expect: ownership of what you touch, straight talk when things get complicated, and the kind of curiosity that makes you actually care about the device on the other end of your Bluetooth connection.
Design, build, and maintain Android apps that communicate with hardware peripherals over BLE
Write performant, reusable, and reliable Kotlin code, the kind people don't dread inheriting
Take part in specifying, planning, and estimating new modules and features
Cover your code with unit tests and keep a TDD mindset where it makes sense
Review pull requests and give your teammates feedback that actually helps
Hunt down bottlenecks and bugs, including the ones that only show up on one OEM
Share what you learn: tech talks, internal docs, pair sessions, whatever fits
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 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 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, 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.
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 both sides can 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.
The entire process is in English. All interviews are recorded for internal evaluation purposes.
Application with a few screening questions
HR call, ~45 min, casual
Technical meeting, ~90 min, with the technical team (may include live coding)
Final feedback within a few days
Once we're in touch, you'll hear from us fast. We don't ghost and we don't 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 you've built that made you proud.
