Senior RUST Systems Engineer - Proxy Appliance

About the Role

The Senior RUST Systems Engineer role focuses on building next-generation edge proxy infrastructure for school networks. This position involves developing high-performance systems software using Rust, Linux, and networking technologies while collaborating with teams across multiple countries.

What You'll Do

• Design, build, test, and maintain production-grade systems software for an edge proxy appliance deployed across large distributed networks.
• Develop high-performance networking components involving TCP stream handling, socket programming, transparent proxying, and network-level traffic management.
• Work close to the Linux operating system, including device drivers, kernel modules, cross-compilation, hardware bring-up, and other embedded Linux components.
• Develop and optimize Rust systems software with a strong focus on reliability, performance, resource efficiency, and maintainability.
• Build and operate containerized workloads suitable for constrained hardware and appliance-based deployments.
• Design and maintain components supporting fleet updates and reliable software delivery across distributed appliances.
• Conduct performance testing, load testing, CPU and memory profiling, and flame graph analysis to identify and resolve bottlenecks.
• Work with AWS services and Infrastructure as Code concepts to support the broader appliance and cloud ecosystem.
• Investigate complex systems and networking issues and develop robust solutions that perform reliably in production environments.
• Collaborate with engineering and cross-functional teams to establish strong development practices and deliver resilient infrastructure.
• Contribute to observability, reliability, and operational improvements across the appliance ecosystem.

Who You Are

• 6+ years of total software engineering experience, including at least 3 years of hands-on production Rust experience in a systems or embedded environment.
• Demonstrated experience developing systems or embedded software rather than primarily application or web-based Rust.
• Strong systems and network programming experience, including TCP stream handling, socket programming, and transparent proxying.
• Practical embedded Linux experience involving areas such as device drivers, kernel modules, cross-compilation, or hardware bring-up.
• Experience with Docker and containerization in constrained environments or appliance deployments.
• Strong understanding of performance engineering, including load testing, memory and CPU profiling, and flame graph analysis.
• Working knowledge of AWS and Infrastructure as Code concepts, with experience using tools such as Terraform or CloudFormation being advantageous.
• Experience with a named fleet, IoT, embedded-device, networking, or hardware-appliance product is strongly preferred.
• Experience with C/C++ or Go alongside Rust is a significant advantage.
• Exposure to eBPF, netfilter, HAProxy, or Envoy is highly desirable.
• Familiarity with RADIUS and observability technologies such as CloudWatch, Splunk, or SLO frameworks is a plus.
• Strong debugging, analytical, and problem-solving abilities, with a focus on building reliable production systems.
• Ability to work effectively in a distributed, remote environment.

Bonus Points

• Experience with C/C++ or Go alongside Rust is a significant advantage.
• Exposure to eBPF, netfilter, HAProxy, or Envoy is highly desirable.
• Familiarity with RADIUS and observability technologies such as CloudWatch, Splunk, or SLO frameworks is a plus.
