Senior Rust Systems Engineer – Edge Proxy & Fleet

About the Role

The Senior Rust Systems Engineer will focus on building and operating core edge infrastructure for on-premise appliances in school networks. This role involves working with Rust on over-the-air updates, control-plane connectivity with AWS, and optimizing network stacks to enhance reliability and performance across a large distributed fleet.

What You'll Do

• Own and develop core components of a fleet-wide edge proxy deployed across thousands of on-premise appliances.
• Build and maintain fleet-wide OTA update capabilities, ensuring reliable software delivery and deployment across distributed devices.
• Develop and optimize control-plane connectivity between deployed appliances and AWS-based infrastructure.
• Design and improve systems and network programming components, including TCP stream handling, socket programming, and transparent proxying.
• Tune network stack performance and system behavior to maintain reliability and efficiency at significant fleet scale.
• Work with embedded Linux environments, including device drivers, kernel modules, cross-compilation, and hardware bring-up as required.
• Build and maintain Docker/containerized workloads designed for constrained appliance environments.
• Conduct performance testing, load testing, memory and CPU profiling, and flame graph analysis to identify and resolve bottlenecks.
• Apply AWS and Infrastructure as Code concepts to support reliable cloud-connected fleet infrastructure.
• Contribute to fleet reliability, observability, operational improvements, and scalable engineering practices.

Who You Are

• 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.

Benefits

• Remote work opportunity within India.
