Job description

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 Italy.

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.


• 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.

Nice-to-have qualifications:

• Experience developing or operating residential proxy networks, peer-to-peer applications, or large-scale device farms.


• Knowledge of browser internals and networking technologies such as Chromium, Cronet, Firefox networking, or anti-detection techniques.


• Background in distributed systems, particularly schedulers, orchestration platforms, control planes, and large-scale infrastructure.


• Familiarity with web scraping technologies and the technical challenges of collecting data from websites at scale.


• Contributions to open-source projects, particularly in the Rust, networking, or mobile development ecosystems.

Benefits:

• Fully remote working environment, with the flexibility to work from wherever you are most productive.


• Flexible working hours within a high-trust and supportive team culture.


• Opportunity to join a self-motivated, progressive, and multicultural international engineering team.


• Access to cutting-edge open-source technologies, modern development tools, and advanced infrastructure.


• Opportunities to attend industry conferences and connect with colleagues from around the world.


• Significant technical ownership and the opportunity to contribute to complex, large-scale engineering projects.


• Exposure to innovative technologies at the intersection of AI, networking, distributed systems, and web data collection.


• A collaborative environment that encourages continuous learning, architectural research, and professional development.

We appreciate your interest and wish you the best!
