Security & Infrastructure Engineer

About the Role

We are looking for a hands-on Lead Security and Infrastructure Engineer to own security, infrastructure operations, and reliability across our cloud, application, and platform environments, including the on-chain rails behind our stablecoin payments.

You'll work directly with the CTO as the founding security and infrastructure hire, and someone the CTO can hand the keys to. You'll be responsible for hardening existing systems, building missing security and infrastructure capabilities, supporting production operations, and establishing the processes and tooling needed as the company scales.

The technology environment includes Google Cloud Platform, Cloud Run, BigQuery, MySQL, Node.js, TypeScript, and Cloudflare, alongside Ethereum and EVM-compatible networks, wallets, stablecoins, and smart contracts. No prior blockchain experience is required, this is a nice to have, not a gate.

This is an ownership role, not a devops role with a security task list. You'll hold full, end to end responsibility for the company's security, sensitive access and critical systems included, with enough infrastructure and DevOps fluency to operate comfortably in a lean, cloud native environment. Security is the center of gravity for this role, roughly two thirds of your time, with infrastructure operations and reliability making up the other third.

What Success Looks Like in Your First 3-6 Months

• Establish clear security ownership, access controls, secrets management, and secure defaults across production systems.

• Improve incident detection, response procedures, runbooks, and post-incident processes.

• Strengthen our cloud, Cloudflare, database, and deployment configurations against security and reliability risks.

• Improve observability across production infrastructure so issues are detected before they impact customers.

• Validate backup, disaster recovery, RTO/RPO, and restoration procedures through hands-on drills.

• Establish a practical roadmap for the security and infrastructure function as the company scales.

Key Responsibilities

Security Engineering

• Own the security posture across cloud, application, and on-chain systems.

• Lead security incident response, including detection, containment, forensics, remediation, and blameless post-mortems.

• Build security tooling, runbooks, and processes that improve incident response over time.

• Establish secure defaults for secrets management, IAM, network segmentation, audit logging, and production access.
