About the Position

  • Help own the architecture and technical roadmap for the iOS platform
  • Contribute to modernization efforts that move the codebase toward a modern, scalable, shared platform underneath multiple apps
  • Balance new feature delivery, legacy maintenance, and platform modernization work as we prepare the app for faster feature delivery
  • Partner closely with our mobile lead, product, design, and engineering leadership on technical direction, and collaborate with mobile engineering partners on shared work
  • Work across a wide surface area of APIs and services, bringing consumer-app polish to an operationally complex, enterprise-scale problem
  • Help set the technical bar for iOS at Zūm: code quality, architecture patterns, and how the team approaches modernization
  • Leverage AI tooling to accelerate development, improve code quality, and speed up modernization work
  • Modernize legacy features of the app toward current SwiftUI patterns without stalling feature delivery
  • Contribute to a shared platform layer that multiple Zūm apps (Driver, Parent, Student, School, Charter) can build on top of, instead of duplicating logic across codebases
  • Rework how the app handles a large and growing surface area of APIs so the codebase stays maintainable as complexity increases
  • Improve app performance and memory footprint, and build out telemetry/monitoring so the team can see how the app behaves in production
  • Help identify which parts of the current app are worth keeping versus updating, and execute
  • 5+ years of professional iOS engineering experience, with real depth
  • Strong, current command of Swift and SwiftUI; you're living in modern iOS development
  • Experience owning meaningful parts of a consumer-facing app end-to-end, not just a single feature, page, or internal tool
  • A product-first orientation: comfortable with infrastructure work, but your track record is primarily product-driven
  • Experience working in a complex, consumer-facing app environment (think feature-rich apps with a large user base vs. a narrow enterprise tool or an SDK)
  • Comfort contributing to architectural decisions and modernization efforts at scale
  • Experience modernizing a legacy iOS app while it's still shipping features (preferred)
  • Background at a company with a small-to-mid-sized mobile team, where you had real hands-on ownership (preferred)
  • Experience partnering with an engineering leader or mobile lead on setting technical direction (preferred)
  • Domain experience in logistics, mapping, or fleet-style products
  • Experience working across multiple related apps sharing common infrastructure or design systems

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
