RealDefense
Android Engineer (Early Career, 1–3 yrs) – Los Angeles, Hybrid – Kotlin/Jetpack Compose + Kotlin Multiplatform
RealDefense is hiring an early-career Android engineer to help build our new privacy and security apps for Android and iOS.
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. Most of our code is shared Kotlin Multiplatform. 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
- Android privacy and security features that go deep into the platform, such as on-device scanning and network filtering
- Subscriptions and accounts with Google Play Billing
- Shared Kotlin Multiplatform and Compose Multiplatform code that ships on both Android and iOS
- Owning features end to end: Play Console releases, policy reviews, crash triage, performance and battery tuning with Android Studio profilers
- 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 Android experience in Kotlin. This role is designed for early-career engineers who want to grow with a mentor.
- At least one app you helped ship to Google Play, from work or your own project
- Solid Kotlin, coroutines and Jetpack Compose 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 Multiplatform and Compose Multiplatform, and to work in Xcode and Swift when shared code runs on iOS
- 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; Android system features such as VpnService, background work or sensitive permissions; any Kotlin Multiplatform experience; 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/4486919974/. Please include a link to a Google Play app you’ve shipped.
