Role overview

We are intent, a 60+ person fully remote company designing and co-creating connected devices since 2008, working with clients like Oura and BOSE and backed by investors like a16z and Founders Fund. We're AI-native and build wearables, smart audio, and health-tech hardware. This role is for Senior iOS Developers who know BLE inside out and enjoy building code that communicates with physical devices. You'll join on a freelance, time & material basis for the first three months, with a potential path to a permanent contract and full benefits if things work out. We look for engineers who ask "why" before "how," challenge assumptions, and take ownership of what they build. The team operates mostly between 10:00 and 18:00 CET with flexible hours, occasional evening calls with US clients, and a Mobile chapter for knowledge-sharing alongside project squads for delivery.

Responsibilities

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

Requirements

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

Benefits

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, 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

Additional details

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
First weeks: space to ramp up before jumping into live project work, paired with a technical buddy, tackle progressively bigger tasks
Feedback comes early and often, no one waits three months to tell you something isn't working
Recruitment process: Application with screening questions, HR call ~45 min casual, Technical meeting ~90 min with technical team (may include live coding), Final feedback within a few days
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
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
Most of the team operates between 10:00 and 18:00 CET, and that's when most meetings happen
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
Pet-friendly office in Warsaw and a coworking space in Gdansk if walls and coffee machines motivate you
Entire process is in English. All interviews are recorded for internal evaluation purposes
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
