🏢 Summary: Freelance Senior Android Developer role focused on building and maintaining high-performance Android applications for IoT and connected device projects. The position involves developing Kotlin-based apps, integrating with Bluetooth Low Energy peripherals, and contributing to architecture and code quality in a remote environment. It offers collaboration on upcoming IoT projects with potential for long-term engagement. 🗂️ Requirements: 3+ years of commercial Android development experience, Strong experience with Kotlin, Experience with Kotlin Coroutines, Experience writing Unit Tests / TDD, Knowledge of Koin and Hilt, Knowledge of Jetpack Compose, Experience with Bluetooth Low Energy communication, B2 level English (written and spoken), Experience reviewing code and maintaining high-quality standards 📃 Skills: Android, Kotlin, Coroutines, UnitTesting, TDD, Koin, Hilt, JetpackCompose, BLE, JUnit, Mockito, Robolectric, MVP, Flutter, Jira, Confluence 🏢 Description: In short 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. 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. 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. 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 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. What you'll do 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 What we're looking for 3+ years writing production Android in commercial projects Strong Kotlin (not "I read about coroutines once") Hands-on BLE integration experience: real apps talking to real peripherals Jetpack Compose in production Comfort with popular Android libraries: Koin, Hilt, and the modern stack Unit testing discipline (JUnit, Mockito, Robolectric, or similar) with a TDD mindset English at B2+, written and spoken, because our clients are mostly US-based Problem-solving over line-counting: we'll take a creative thinker over a fast typist any day High coding standards and an eye on what's new in the Android world Initiative, ownership, and the kind of communication where people don't have to guess what you meant Nice to have Solid grasp of architecture and design patterns Previous IoT or connected device projects Functional reactive programming (Flow, RxJava) Google Play release experience and Android Auto Agile or Scrum delivery experience Some Flutter experience Genuine curiosity about the things you build, not just the code behind them 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 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 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. Recruitment process 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. 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.
