Your job is not to review and say no — it is to engineer the secure defaults, golden paths, and guardrails-as-code that make the secure way to build the easy way to build, across cloud, infrastructure, and CI/CD. You will design, build, and operate the IaC modules, pipeline templates, internal libraries, and policy-as-code controls that the rest of the company consumes. You will engineer guardrails that block or flag the insecure path automatically, and replace recurring manual security work with durable mechanisms that don't depend on anyone remembering to do the right thing. As one of the most senior engineers on the team, you'll help shape and drive the technical direction for how secure-by-default works at Shield AI — partnering closely with a hands-on engineering lead — and raise the bar for everyone building on top of it. This is a hands-on, build-heavy role. We are credible because we are technical — you'll read the code, the configs, the telemetry, and the architecture, and ship solutions durable enough to run without you.
