About The Position

We are looking for a Senior/Staff Site Reliability Engineer - Edge to own the 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.

Requirements

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.

Responsibilities

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.
