What we’re looking for:

We have three hard requirements for this role—you must:

Have at least three years of professional software development experience. (Five or more is better!)
Have at least three years of experience writing native iOS apps.
Live somewhere between the Pacific Time Zone (UTC-8) and the Central European Time Zone (UTC+1). (Think of a world map moving left to right from PT to CET—those time zones are all OK.)

Beyond that, we’re open-minded. We value a wide range of experience and skills and recognize every career path is unique. In case this helps you determine your interest and fit, here’s a glimpse of some of the tech you’ll encounter:

You’d be stepping into a mature codebase with native UI and app infrastructure combined with cross-platform shared business logic in a client-server setting.
The native side is a modern Swift codebase. Extensive use of Swift Concurrency. UIKit appears in older flows, but newer work is SwiftUI. A tiny Objective‑C layer remains for long‑lived utilities.
The app is highly modular, split into many internal Swift Package Manager modules, and grouped into Core, Application, and Presentation packages—so you don’t have to recompile the world when you change one feature.
Feature flags, “Labs” builds, and a dedicated “Debug” module makes it easy to experiment and roll changes out gradually.
We share cross-platform business logic through a packaged JavaScript library and Kotlin Multiplatform. It’s a big plus if you have a little experience with TypeScript or Kotlin.
The app is local-first: data is stored in SQLite through FMDB with a custom query layer and background‑sync engine.
Swift Package Manager manages dependencies and internal modules. Fastlane drives build configurations with Match handling certificates and provisioning profiles. Bitrise runs these pipelines. Around that sit a Makefile, Bash and Ruby helper scripts, pre‑commit Git hooks, SwiftLint, and some other niceties that run automatically.
There are multiple app surfaces: native App Intents, WidgetKit widgets, plus a basic watchOS companion.
While we have a QA team to help, quality is developer-driven. We have dedicated Unit and UI test targets, and run them automatically in CI. A home‑grown page‑object framework and many helper extensions keep UI tests readable and (comparatively) easy to develop.

If you like building consumer‑facing experiences across the entire Apple ecosystem—while working with modern Swift tools, thoughtfully shared logic, a nice CI/CD pipeline, and plenty of room to ship impactful things—you’ll feel right at home here.

On a day to day basis, you’ll:

Architect, design, develop, test, deploy, monitor, troubleshoot, and maintain code for product initiatives, platform roadmaps, and infrastructure projects.
Regularly work closely with PMs, Designers, QA, Marketing, and Support. You’ll:
Brainstorm with product team members on new features and changes to existing functionality.
Review UI/UX designs and offer product-related design suggestions and platform-specific feedback.
Work with PMs and designers to provide technical feasibility and effort guidance and break down designs into tightly scoped development plans.
Work with Support to investigate and solve tricky customer issues.
Collaborate with QA to ensure our combined testing methods give us confidence in our quality.
Periodically serve as the Mobile Release Owner, which means you’ll:
Shepherd the next version of the iOS app through the mobile release process.
Be the single point of contact for the release.
Drive solutions and enlist help from others for any issues or regressions found during the release flow.
Help monitor and maintain all aspects of our iOS platform. For example, you’ll:
Proactively fix production-related issues.
Keep an eye on system logs and crash reports.
Stay current on iOS trends and upcoming versions.
Apply security patches and update third-party libraries.

You may also:

Eventually have the opportunity to contribute to the Engineering team in an additional capacity. Our Engineering department features a unique peer-to-peer, non-hierarchical leadership style with separate roles for technical stewardship and people management.
For example, you could in time serve as a:
DRI (Directly Responsible Individual). A DRI is the point person for one area of our technology. A DRI may not be the technical expert in all aspects of their area, but they keep us pointed in the right direction. And, while we enjoy consensus, DRIs can make a call if necessary to keep us moving forward.
People manager. Engineering managers at YNAB don’t dictate priorities or assign resources. Instead, they serve as the connection between their reports and the company. Engineering managers often do not work on the same project or even in the same platform stack as the people they manage, so this role is less about giving technical feedback (we rely on peers for that) and more about having an affinity for the people side of things, being great at helping others flourish.
Both the DRI and Engineering Manager roles are part-time, only requiring a portion of each workweek. This allows DRIs and managers to remain individual contributors first and foremost—a key part of our structure and culture.
These additional roles are not promotions but simply different ways of contributing.

That’s a lot of bullet points, but let’s still say that your success as an iOS engineer at YNAB will depend on you being a systems thinker who loves to collaborate with others to solve problems. In doing so, you’ll need to consider a solution’s entire architecture and lifespan, and think deeply about the implications of various technical choices, including scalability, security, pragmatism, and future maintenance. You’ll measure your success not just by code shipped or isolated tasks completed, but by problems effectively solved and value added to the overall project. It’s this combination of ownership and teamwork that ensures that our applications and the different parts of our software work well together, ultimately improving the overall quality of our tech.

If this sounds like your kind of place, we can’t wait to hear from you.
