Staff Infrastructure and Security Engineer

Jobtailor; Chicago (IL); On-site; USD 140,000 - 190,000; Full time

Job summary

Jobtailor in Chicago (IL) seeks an experienced Infra & Security technical lead to own the cloud platform end-to-end, drive automation, and simplify architecture for security and reliability.

You will lead incident response, unify identity management, and build production-agent infrastructure to support autonomous agents, while advancing compliance and supply-chain scanning programs.

Qualifications

• Deep cloud engineering experience in AWS designing and operating production infrastructure at scale.
• Strong CI/CD and delivery automation and IaC, with ownership of production reliability.
• Apply security pragmatically with isolation, least-privilege, RBAC.
• A formal background in information security or cybersecurity, including leading a SOC 2 audit.
• Has led at least one enterprise security-breach or data-leak incident response.
• Hands-on technical lead capable of setting direction and reviewing code.
• AI-forward: design for isolation, safe data, and non-human identity.
• Communicate crisply across engineering, IT/Security, Legal, and Finance.

Responsibilities

• Serve as the technical DRI for the Infra & Security group: own the architecture, set the standards, and make the technical calls across infrastructure, DevOps, and security engineering.
• Own the cloud platform end-to-end: infrastructure reliability, CI/CD and delivery automation, and the infrastructure-as-code beneath them.
• Drive a simpler, isolated architecture through shrinking the surface area we defend and maintain: retire legacy and unused services, consolidate SaaS and vendors, and unwind standing external dependencies.
• Own infra & security incident-response: a staffed rotation with no single point of failure, severity-matched response, actionable alerting, and runbooks.
• Bring identity and access under a single source of truth: human, service, machine, and agent identity.
• Build the Production-agent Infrastructure that lets autonomous agents run and self-verify safely in production.
• Drive and maintain our security-compliance and supply-chain scanning programs.

Job description

• Serve as the technical DRI for the Infra & Security group: own the architecture, set the standards, and make the technical calls across infrastructure, DevOps, and security engineering.
• Own the cloud platform end-to-end: infrastructure reliability, CI/CD and delivery automation, and the infrastructure-as-code beneath them.
• Drive a simpler, isolated architecture through shrinking the surface area we defend and maintain: Retire legacy and unused services, consolidate SaaS and vendors, and unwind standing external dependencies.
• Own infra & security incident-response: a staffed rotation with no single point of failure, severity-matched response, actionable alerting, and runbooks.
• Bring identity and access under a single source of truth: human, service, machine, and agent identity.
• Build the Production-agent Infrastructure that lets autonomous agents run and self-verify safely in production.
• Drive and maintain our security-compliance and supply-chain scanning programs.

Requirements

• Deep cloud engineering experience, primarily in AWS: designing, building, and operating production infrastructure at scale.
• Strong in CI/CD and delivery automation (CircleCI, Nomad, or equivalent) and infrastructure-as-code (Terraform), with ownership of a real production system's reliability.
• Apply security pragmatically: isolation, least-privilege, RBAC, blast-radius containment.
• A formal background in information security or cybersecurity, including having led a SOC 2 (or similar) compliance audit.
• Has led at least one enterprise security-breach or data-leak incident response.
• Comfortable as a hands-on technical lead and DRI: work through architecture, standards, and code review, set technical direction, and raise the bar across a team.
• A bias toward simplicity and subtraction.
• AI-forward: build for isolation, safe data, and non-human identity, and the infrastructure behind it.
• Communicate crisply across engineering, IT/Security, Legal, and Finance.

Core Competencies

Demonstrates expertise in cloud engineering, particularly in AWS, with a focus on infrastructure reliability, CI/CD and security compliance. Capable of leading incident response efforts and driving architectural decisions while ensuring simplicity and security across systems.
