/ AboutThe team behind Parameter./ CareersOpen roles. Come build with us.BlogSign inBook a call[ engineering ]Member of Technical Staff, InfrastructureFull time • San Francisco, CA • $180K – $240KApplyParameter builds AI agents that do offensive security work. Our agents run autonomous penetration tests against production applications and cloud environments, finding IDORs, broken access control, XSS, and infrastructure misconfigurations that scanners miss and that human pentest firms only look for once or twice a year.We are not a theoretical security company.

Our team has responsibly disclosed real, high-severity vulnerabilities to well-known technology companies, and our findings are the front door to most of our customer relationships.Our agents run for hours, in parallel, against live customer infrastructure, and they are expensive when they run badly. You own the platform underneath them: the orchestration, the isolation between one customer's engagement and the next, and the difference between a run that fails loudly and one that quietly bills us for a weekend.The title points at where you'll spend most of your time.

Expect the rest of the week to go wherever the work is: agent systems one day, the product the next, a customer call or a report that has to go out after that. We are small enough that everyone works across every product, and we hire people who want that.What you'll doOwn the infrastructure the agents run on: orchestration, scheduling, isolation between customer environments, and the blast radius when a run goes wrongRun our GCP footprint, including networking, IAM, secrets management, and the egress paths agents test throughKeep long-running Temporal workflows durable across restarts, provider rate limits, and model outagesBuild the deployment and observability story: CI/CD, tracing across multi-hour agent runs, and cost attribution per engagementHarden the platform we sell security from.
