Senior Site Reliability Engineer - Edge Location: Ottawa/Toronto, On-Site Reports to: Head of Architecture & Security The role We are looking for a Senior/Staff Site Reliability Engineer - Edge to own edge compute module: the standard hardware + OS + runtime that integrates cleanly with our mesh radios, sensors, and the AuraNet SDK. One module. Reproducible. Hardened. Field-ready. Concretely, that means owning the path from a developer prototyping fast on the bench to a locked-down device a customer deploys in the field — without those being two different worlds held together by tribal knowledge. First 6–12 months (what good looks like) A standard, documented provisioning pipeline — image build, flash, config, attest — replacing today's one-off, misconfigured boxes. A hardened base OS baseline across all nodes. We want to move to SELinux-enforcing as the default, not an afterthought. You'll drive this with Security (you'll work directly with our Head of Security). Secure boot + supply-chain integrity from silicon to running workload: signed images, verified provenance, no mystery binaries. A dev-to-field story: fast internal prototyping that translates into a hardened, reproducible field build with no rewrite. Observability that survives DDIL — telemetry that works within real link, power, and thermal budgets, and that doubles as a security signal. What you'll do day to day Build and maintain the standard edge module and its provisioning/lifecycle tooling. Define the reliability story from scratch: what "up" means at the edge, what we measure, what budgets we operate within. (No SLOs exist yet — you set them.) Harden images, enforce supply-chain integrity, stand up secure boot and attestation. Make the module integrate cleanly with mesh radios, sensors, and the AuraNet SDK. Partner tightly with Security on the hardened baseline — you are a co-owner of that posture, not a downstream consumer of it. Kill tribal knowledge: document, standardize, automate procurement and provisioning. Must-haves Senior/Staff-level depth running Linux at the edge — embedded/SBC reality, not just cloud VMs. Real DDIL experience: you've built things that work disconnected, intermittent, and bandwidth/power-constrained, and you design for it instinctively. Edge / embedded fluency: Jetson-class compute, ARM, ROS, cross-compilation, the works. Strong networking fundamentals — you can reason about and debug a constrained, multi-hop network down to the packet. Comfort owning a greenfield function: you impose order on chaos and like it. Nice-to-haves Mesh / RF experience (we live here). Defence or regulated-industry background. Hands-on with SELinux, secure boot, TPM/attestation, reproducible builds, supply-chain tooling. Cold/thermal/environmental hardware testing exposure. No defence background required.
