Senior iOS Developer (freelance)

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.

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

The company 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.

What we're looking for

• 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
