Do you love crafting beautiful and functional customer experiences? Want to work on interesting technical problems for an iOS application around booking flows and payments? Do you have a passion for Swift and Native iOS development with a focus on building reliable applications at scale? Peek is looking for a Senior iOS Engineer. The ideal candidate has 5+ years of development experience with Swift, designing, building, and maintaining robust applications at scale that integrate with multiple backend services. In this role you will have the opportunity to take ownership of critical product areas and use AI tools as a force multiplier on top of your strong fundamentals.

We’re hiring a Senior iOS Engineer who works AI-first. That means you treat AI as a core part of how you build software and break down ambiguous problems, including delegating tasks to agents, reviewing their work critically, and course-correcting when things go sideways. You'll design and operate complex agent orchestration systems, develop patterns for human-agent collaboration, and ship real product features primarily through agent-assisted development in collaboration with human colleagues.

We work collaboratively, move fast, and value technical quality. If you are excited about the challenge of building an incredible product while working alongside a great engineering team, we’d love to hear from you!
What we’re looking for

-
Strong mobile fundamentals in iOS: API integration, data modeling, robust system design, application reliability, and debugging production issues.

-
Clear and empathetic communicator: you flag when a spec has holes, you can articulate why you made a technical choice, you enjoy collaboration and seek to understand different perspectives, and you are constructive in any disagreements.

-
Self-motivation and ownership: you will push your work forward without prompting and look for ways to unblock yourself and the team on business priorities; you enjoy o
