Job summary

Jobgether on behalf of a partner company seeks a Software Engineer (Edge – Devices & Mobile) based in the United Arab Emirates. You will build a cross-platform Rust peer runtime across Windows, Android, and Linux, with future macOS support, focusing on reliability, security, and seamless performance.

You will collaborate with senior engineers, tackle complex systems, and contribute to large-scale data collection and device infrastructure projects in a remote-first, globally distributed team.

Qualifications

• At least 5 years of professional experience developing, shipping, and maintaining production-grade software using Rust.
• Proven experience building and deploying cross-platform Rust applications on at least two operating systems among Windows, macOS, and Android, including experience with at least one mobile platform.
• Strong understanding of operating system internals, process management, permissions, background execution, and platform-specific constraints.
• Hands-on experience with FFI and integrating Rust with C/C++ libraries and native operating system APIs, including JNI/NDK, Win32, and POSIX interfaces.
• Solid knowledge of networking protocols, particularly TCP, TLS, and HTTP, with the ability to inspect network traffic, understand protocol-level behavior, and analyze client fingerprint differences.
• Experience with asynchronous programming and networking in Rust, ideally using technologies such as Tokio and Tonic.
• Strong focus on software reliability, observability, performance monitoring, and production operations, including the ability to measure and troubleshoot distributed device fleets remotely.
• Good understanding of secure software design, particularly when deploying and operating software on third-party devices and environments.
• Excellent written communication skills and the ability to collaborate effectively within a globally distributed, remote-first engineering team.
• Strong analytical and problem-solving abilities, combined with intellectual curiosity and an interest in reverse engineering, networking technologies, and complex systems.
• Familiarity with technologies such as gRPC, Protocol Buffers, mutual TLS (mTLS), Chromium networking, Kotlin, Java, Prometheus, Grafana, OpenTelemetry, Kubernetes, and cloud infrastructure is advantageous.

Responsibilities

• 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.
