Senior Rust Systems Engineer – Edge Proxy & Fleet

Accountabilities: • 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.

Requirements:

• 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.

• Direct-hire opportunity in a senior systems engineering capacity.

• Opportunity to work on infrastructure deployed across thousands of distributed on-premise appliances.

• Hands-on exposure to advanced Rust systems programming, embedded Linux, networking, and edge infrastructure.

• Opportunity to work across AWS, Infrastructure as Code, Docker, performance engineering, and fleet management.

• Collaboration with distributed engineering teams across India, the US, and the UK.

• High-impact ownership of production infrastructure where reliability and scalability are essential.

• Exposure to technically challenging areas including OTA updates, control-plane connectivity, network stack optimization, and large-scale device fleets.
