Senior iOS Developer

🏢 Summary: Freelance Senior iOS Developer role focused on building and maintaining iOS applications that communicate with connected hardware devices over BLE. The position involves close collaboration with firmware and product teams, strong ownership, TDD practices, and daily use of AI tools, with a potential path to a permanent contract after an initial 3‑month period. Fully remote with flexible hours and B2B hourly compensation. 🗂️ Requirements: 6+ years of production experience in Swift, Strong hands-on experience with BLE integration, Experience with structured concurrency in Swift, Experience with CI/CD tools (GitHub Actions, Bitrise, or Travis), Experience with unit testing frameworks (XCTest, Quick/Nimble) and TDD, English proficiency at B2+ level, Ability to work with high coding standards and modern iOS practices 📃 Skills: Swift, BLE, XCTest, Quick, Nimble, CI/CD, GitHub, Bitrise, Travis, Combine, RxSwift, TDD, Agile, Scrum, AI 🏢 Description: 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. 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. Job requirements What we're looking for 6+ 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
