Software Engineer (Mobile SDK)

Join our WARP Mobile SDK team as a Senior Software Engineer. In this role, you will define the client architecture and public APIs for native iOS and Android SDKs, establish foundations that are testable and well-documented, and set standards for compatibility, diagnostics, performance, and release quality across mobile platforms. You will work closely with product and engineering partners, mentor native mobile engineers, and help resolve complex customer integration issues. Enjoy competitive pay, take-what-you-need vacation, paid maternity and paternity leave, comprehensive employee benefits, a commuter program, and wellbeing support.

- You will be successful in this role if you combine strong native engineering judgment and a track record of carrying distributed software from design through production operation
- Understanding of mobile package distribution, source and binary compatibility, dependency management, and reliable release practices
- Experience mentoring engineers and raising a team's technical bar through design review, code review, and knowledge sharing
- Experience designing or owning customer-distributed SDKs, libraries, or similarly constrained developer-facing products
- Experience diagnosing production issues that cross application, SDK, network, and service boundaries, while designing safe diagnostics that do not expose sensitive data
- Deep experience building production software for either iOS with Swift or Android with Kotlin, and enough familiarity with the other ecosystem to guide shared architectural decisions
- Experience writing technical designs and aligning decisions across product, client, backend, edge, and security teams
- Experience with mobile platform security concepts, including app and device integrity, secure key storage, application signing, authentication, and secure communications
- Familiarity with native mobile networking stacks, HTTP APIs, and the integration challenges introduced by different application architectures and networking libraries
- Empathetic, proactive, and constructive written and verbal communication skills
- Proven ability to operate within strict mobile performance budgets, including binary size, battery use, startup time, and main-thread overhead
- Familiarity with how native SDKs are consumed by cross-platform frameworks such as React Native and Flutter is a plus
- Familiarity with lower-level languages like C++ or Rust for high-performance, cross-platform security modules is a plus
