  • Practical Engineering Capabilities: Solid hands-on experience using Python (or similar) to automate tasks, Terraform to manage infrastructure, connect APIs, and manage infrastructure state, balanced with the judgement to use UI configurations when code isn't viable.
  • Cloud & Infrastructure Literacy: Proven experience configuring or hardening security controls within cloud (AWS/GCP) environments (e.g. IAM and network/identity boundaries) and handling data formats like JSON to parse logs.
  • AI-First Execution: Enthusiastic about actively leveraging advanced AI coding tools (such as Claude Code, Codex) to exponentially increase your engineering output, script generation, and delivery speed.
  • Pragmatic Security Mindset: A builder who views security as a business enabler. You focus on building practical defensive posture rather than filling out compliance checklists, with the instinct to identify actual systemic risk based on context.
  • Bias for Action: An execution-focused operator. When a security control drifts or a peer needs a detection mechanism, you write the script, open the PR, or modify the control to get it done.
  • Communication & Collaboration: The ability to debate technical IAM architecture details with a Platform Engineer and seamlessly explain to non-technical risk stakeholders why a specific control change matters.
