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 Austria.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.- Versátil 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.#J-18808-Ljbffr
