Vacant job

We’re looking for an experienced iOS Engineer to join a team working on system-level components, background services, and platform logic within iOS. This role is ideal for someone who enjoys understanding how things work under the hood, building reliable low-level functionality, and contributing to software that runs seamlessly on millions of devices worldwide.

What you’ll do

Design and build system services and daemons that operate reliably over long runtimes.

Work close to the OS layer, contributing to performance, stability, and platform integrity.

Collaborate with cross-functional teams to evolve internal frameworks and APIs.

Investigate and resolve complex issues related to threads, concurrency, and system behavior.

What we’re looking for

Problem-solving clarity – Ability to explain your thinking, ask clarifying questions, and iterate from simple to optimized solutions.

Technical fundamentals – Can reason about complexity, understand practical trade-offs, and write clean code.

Communication – Easy to talk to, take feedback without defensiveness, and discuss assumptions explicitly.

Genuine enthusiasm – Show real interest in hard problems, not just getting a job.

Learning agility – Willing to pick up new technology, work with legacy code, and adapt quickly.

Must have

6+ years of experience in iOS development (Swift, Objective-C).

Solid understanding of computer science fundamentals — algorithms, data structures, and architecture. Ideally M.Sc. Computer Science.

Strong knowledge of threads, concurrency, and asynchronous programming (async/await, GCD, etc.).

Proven ability to write robust, fault-tolerant, and efficient code for background or long-running processes.

Clear communication skills and fluent English; Swedish is considered meritorious.

Nice to have

Experience developing system services, frameworks, or daemons on iOS or macOS.

Knowledge of security, privacy, encryption, or communication protocols.

Experience with complex or distributed systems.

Familiarity with Bluetooth or other low-level communication layers.

Deep understanding of modern Swift concurrency (structured concurrency, actors, async/await).

Join a technically driven environment where depth of understanding and reliability matter. You’ll be part of a small, skilled team solving challenges that make iOS systems more stable, efficient, and intelligent.
