Software Engineer (Edge - Devices & Mobile)

About the role

This position is listed on behalf of a partner company, which manages all applications and next steps. Our partner is looking for a Software Engineer (Edge – Devices & Mobile) based in Chile.

We are looking for an experienced Software Engineer with strong Rust expertise to help build and scale a sophisticated, cross-platform device infrastructure. In this role, you will develop and maintain a reliable peer runtime across Windows, Android, and Linux, with future expansion to macOS. You will work at the intersection of systems engineering, mobile platforms, networking, and distributed infrastructure. A key focus will be bringing advanced capabilities to mobile devices while ensuring seamless performance, security, and reliability across a globally distributed fleet. You will collaborate closely with senior engineers and cross-functional teams to solve complex technical challenges. This is an opportunity to take significant ownership of critical infrastructure, influence architectural decisions, and contribute to innovative large-scale data collection systems.

Accountabilities: - Design, develop, and maintain a cross-platform Rust peer runtime supporting Windows, Android, and Linux, with future compatibility for macOS.

- Manage process lifecycles, background execution, networking, automatic updates, and operational stability across diverse and unmanaged hardware environments.

- Lead the expansion of the platform to Android devices using NDK and JNI, addressing foreground services, battery optimization, mobile network constraints, and integration with real and emulated device environments.

- Integrate native networking technologies, including Chromium's network stack (Cronet and C++), and browserless HTTP clients into well-structured, reliable Rust libraries.

- Work with native operating system APIs and foreign function interfaces (FFI), ensuring safe memory management, ownership, and cross-language interoperability.

- Collect and analyze hardware and operating system signals, including TCP, TLS, and HTTP fingerprints, to improve network realism and support collaboration with browser and anti-detection engineering teams.

- Develop comprehensive device-level observability and performance metrics, monitoring uptime, bandwidth consumption, device availability, drop-off rates, and task success rates.

- Expand peer capabilities to support additional workloads, including CAPTCHA solving and browser rendering, while maintaining strong security boundaries around untrusted content and environments.

- Participate in on-call rotations, investigate production incidents, conduct post-mortems, and implement improvements to system reliability and deployment processes.

- Contribute to technical documentation, architecture proposals, design reviews, and engineering standards, helping establish best practices for cross-platform Rust development.

Requirements:

- At least 5 years of professional experience developing, shipping, and maintaining production-grade software using Rust.
