Senior Rust Systems Engineer – Edge Proxy & Fleet
Summary
A senior Rust engineer who owns fleet-wide software for Securly's on-premise proxy appliances deployed across thousands of K-12 school networks — handling OTA updates, control-plane connectivity to AWS, and network stack tuning. Core stack is production Rust for systems/network programming on embedded Linux, with Docker and AWS.
Senior Rust Systems Engineer – Edge Proxy & Fleet
Remote, India | Direct Hire | 6+ Years Total (3+ Years Production Rust)
About Securly
Securly is a K-12 EdTech company built around one mission: keeping students safe and well, both online and off. Our platform gives schools the infrastructure to filter and monitor web traffic, flag signs of self-harm or bullying, and support student wellness — all while giving IT teams tools that hold up on real school networks, not just in a demo. That mission runs straight through this role: the edge proxy appliance is core infrastructure sitting inside thousands of school networks, and it has to work every single school day, at scale, without fail.
We're a team of roughly 330 people across Pune, the US, and the UK, working across engineering, product, and customer-facing teams to build and support that platform. Engineering in Pune plays a central role in building the systems that make Securly's safety mission possible — this isn't a satellite team, it's where core infrastructure like this gets built.
The Role
We're looking for a Rust systems engineer to own core parts of the fleet-wide proxy running across thousands of on-premise appliances deployed in school networks — fleet-wide OTA updates, control-plane connectivity back to AWS, and the network stack tuning that keeps it all running reliably at scale.
Must-Haves:
- 3+ years hands-on production Rust in a systems or embedded context (not app/web Rust)
- 6+ years total engineering experience
- Systems/network programming — TCP stream handling, socket programming, transparent proxying
- Embedded Linux fundamentals — device drivers, kernel modules, cross-compilation, or hardware bring-up
- Docker/containerization for constrained/appliance deployment
- Performance testing and profiling — load testing, memory/CPU profiling, flame graph analysis
- Working knowledge of AWS and IaC concepts
Strongly Preferred: Prior fleet management or IoT device fleet experience, C/C++ or Go alongside Rust, eBPF/netfilter/HAProxy/Envoy exposure
Nice to Have: RADIUS, observability (CloudWatch/Splunk/SLOs)
Securly is an Equal Opportunity Employer. All qualified applicants receive consideration regardless of race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, veteran status, or other legally protected characteristic.
