Build privacy and security applications for iOS and Android using Swift, SwiftUI, Kotlin Multiplatform, and Apple system extensions. Own features through testing, TestFlight, App Store review, crash triage, and performance optimization. Develop subscription and account functionality with StoreKit 2, collaborate with a small mobile team, and use AI coding agents while maintaining code quality. The role includes mentorship and requires hybrid work from the Westchester office three days per week.
RealDefense is hiring an early-career iOS engineer to help build our new privacy and security apps for iOS and Android.
We’re the LA company behind iolo System Mechanic and SUPERAntiSpyware, protecting over 3 million customers. Our mobile team is small and early-stage, so you’ll help shape both the apps and the shared platform they run on. You’ll work directly with our head of mobile, who sets the architecture, still writes code and mentors the team.
What you’ll work on
- Privacy and security features built on Apple’s system extensions: content blocking and network filtering
- Subscriptions and accounts with StoreKit 2
- Swift and SwiftUI for the iOS experience, plus shared Kotlin (Kotlin Multiplatform)
- Owning features end to end: TestFlight, App Store review, crash triage, performance tuning with Instruments
- Working with AI coding agents every day: planning, keeping each step small and tested, and reviewing what the agent writes
What we’re looking for
- 1–3 years of professional iOS experience in Swift. This role is designed for early-career engineers who want to grow with a mentor.
- At least one app you helped ship to the App Store, from work or your own project
- Solid Swift and SwiftUI fundamentals, with unit and UI tests as part of how you ship
- Daily use of AI coding agents (Claude Code, Cursor, Copilot agent mode or similar), with the ability to explain every line you ship
- Willingness to learn Kotlin and Kotlin Multiplatform
- Based in the LA area and able to work from our Westchester office Tue/Wed/Thu
Nice to have: personal, open source or hackathon apps; app extensions (content blockers, Network Extension, widgets); any Kotlin; interest in privacy and security.
Pay: $70,000–$80,000 per year, plus benefits
Type: Full-time · Hybrid, 3 days in office · Local candidates only
To apply: Apply on LinkedIn: https://www.linkedin.com/jobs/view/4486913828/. Please include a link to an App Store app you’ve shipped.
RealDefense is an equal opportunity employer.
