Senior Rust Systems Engineer – Edge Proxy & Fleet

This is a senior systems engineering role focused on building and operating core edge infrastructure deployed across thousands of on-premise appliances in school networks. You’ll work primarily in Rust on fleet-wide over-the-air updates, control-plane connectivity with AWS, and network stack optimization. The role combines systems programming, embedded Linux, networking, containerization, and cloud infrastructure. You’ll be responsible for improving reliability, performance, and scalability across a large distributed appliance fleet. The environment offers the opportunity to work on production infrastructure where resilience and efficient resource usage are critical. You’ll collaborate with engineering teams across India, the US, and the UK while owning technically challenging systems-level initiatives.

• 6+ years of total software engineering experience, including 3+ years of hands-on production Rust development.
• Strong production Rust experience specifically in systems or embedded environments rather than application, web, or backend development.
• Proven experience with systems and network programming, including TCP stream handling, socket programming, and transparent proxying.
• Solid embedded Linux fundamentals, with experience in areas such as device drivers, kernel modules, cross-compilation, or hardware bring-up.
• Hands-on Docker and containerization experience for constrained systems or appliance deployments.
• Experience with performance testing and profiling, including load testing, CPU and memory profiling, and flame graph analysis.
• Working knowledge of AWS and Infrastructure as Code concepts, with exposure to tools such as Terraform or CloudFormation.
• Fleet management or IoT device fleet experience is strongly preferred.
• Additional experience with C/C++ or Go alongside Rust is advantageous.
• Exposure to Linux kernel networking technologies such as eBPF or netfilter, or high-performance proxy/load-balancing technologies such as HAProxy or Envoy, is a plus.
• Familiarity with RADIUS and observability practices involving tools or concepts such as CloudWatch, Splunk, and SLOs is beneficial.
• Strong troubleshooting, analytical, and problem-solving abilities, with the ability to investigate complex systems-level issues.
• Ability to work independently on technically demanding infrastructure while collaborating effectively across distributed engineering teams.
• Experience working on production systems where reliability, performance, scalability, and resource efficiency are critical.
