Skills
Must have
- 3+ years writing production Swift
- Strong, hands-on BLE integration experience (not "I read about it once")
- Structured concurrency in Swift: you know it, you use it
- CI/CD experience: GitHub Actions, Bitrise, or Travis
- Unit testing discipline: XCTest, Quick/Nimble, 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 iOS world
- Initiative, ownership, and the kind of communication where people don't have to guess what you meant
Nice to have
- Experience with other mobile platforms (Android, Flutter, KMM)
- Previous IoT or connected device projects
- Functional reactive programming (Combine, RxSwift)
- Agile/Scrum experience
- Genuine curiosity about the things you build, not just the code behind them
Full description
In short
If you're a Senior iOS Developer who knows BLE inside out and likes 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 Swift 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
- Build and maintain iOS apps that communicate with hardware peripherals over BLE
- Take part in specifying, planning, and estimating new modules and features
- Write and maintain unit tests (XCTest, Quick/Nimble) with a TDD mindset
- Keep CI/CD pipelines in shape (GitHub Actions, Bitrise, Travis)
- Review pull requests and give your teammates feedback that actually helps
- Share what you learn: tech talks, internal docs, pair sessions, whatever fits
- Work side by side with firmware engineers, designers, QA, and PMs
- 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 project squad led by a PM for day-to-day delivery.
