Infrastructure Security Engineer

Cast & Crew is an entertainment technology and services provider supporting the global entertainment industry through software, payroll products, data and reporting, and creative tools. The Infrastructure Security Engineer will operate offensive security and vulnerability management programs, manage bug bounty, scanning, CSPM, and red-team platforms, and drive findings through validated remediation. The role also evaluates emerging AI-enabled security tooling and supports network and perimeter security operations.

Responsibilities:

• Oversee day-to-day operation of the bug bounty program, including program scope, policy, response targets, and researcher communications
• Triage inbound submissions: reproduce and validate findings, de-duplicate against known issues, assign severity, and reject out-of-scope or invalid reports with clear rationale
• Make and defend bounty award decisions in coordination with the platform provider and Security leadership
• Route confirmed findings to the owning engineering or infrastructure team, track them to closure, and verify fixes before the report is closed
• Use recurring submission patterns to drive systemic fixes, scope adjustments, and secure-development feedback rather than one-off patches
• Manage and operate enterprise vulnerability scanners across cloud, on-premise, and hybrid assets, ensuring coverage of the full asset inventory and investigating scanning gaps
• Configure, tune, and maintain scan policies, credentialed scanning, authenticated checks, and scan schedules to maximize signal and minimize disruption
• Triage and prioritize findings using exploitability, asset criticality, and business context (e.g., CVSS, EPSS, CISA KEV, threat intelligence)
• Assign findings to the correct engineering and infrastructure owners, negotiate remediation timelines, and verify remediation through re-scan or manual validation
• Track remediation against SLAs, escalate aging findings, and manage the exception and risk-acceptance process with the GRC team
• Produce metrics and reporting on coverage, backlog, mean time to remediate, and SLA compliance for engineering and executive audiences
• Monitor emerging CVEs, assess applicability to our environment, and coordinate emergency patching when critical vulnerabilities arise
• Manage and operate the CSPM platform across our multi-cloud environment, including onboarding new accounts, subscriptions, and projects
• Tune policies and baselines, suppress noise, and maintain exception handling so that surfaced findings are consistently actionable
• Drive remediation of misconfigurations with cloud and platform owners, and verify that fixes hold over time
• Enforce least-privilege access principles and audit cloud permissions, IAM policies, security groups, SCPs, and guardrails on a recurring basis
• Support secure architecture reviews for new cloud infrastructure and services
• Manage and operate the agentic red-team pentesting platform, including target scoping, scheduling, credentials, and environment onboarding
• Define and enforce rules of engagement and safety guardrails so that automated testing does not disrupt production systems
• Validate platform output, eliminate false positives, and translate confirmed attack paths into concrete, owner-assigned remediation items
• Feed results into the same triage, prioritization, and verification workflow used for scanner and bug bounty findings so there is one prioritized view of risk
• Coordinate with third-party penetration testers and use platform coverage to focus manual testing where it adds the most value
• Research, pilot, and benchmark emerging security products, including AI-driven and agentic tooling, against real problems in our environment rather than vendor demos
• Run structured proofs of concept: define success criteria up front, test against known findings, and make a clear recommendation to adopt, defer, or reject
• Deploy and integrate selected tooling into existing workflows and ticketing, and own it operationally once it is in production
• Automate repetitive triage, enrichment, and reporting work so that engineering time goes to remediation rather than data handling
• Support enterprise network security infrastructure including firewalls, IDS/IPS, proxies, VPNs, and DDoS mitigation
• Perform firewall rule reviews and access control audits to reduce attack surface
• Investigate anomalous network activity surfaced by security tooling and escalate to incident response as needed

Requirements:

• • 3–5 years of experience in infrastructure, network, or cloud security roles
• • Experience running or supporting an enterprise vulnerability management program end-to-end, from scanner operation through verified remediation
• • Demonstrated ability to triage security findings: reproduce issues, judge real-world exploitability, de-duplicate, and prioritize against business context rather than raw severity scores
• • Deep, practical understanding of common vulnerability classes and how they are actually exploited — remote code execution, injection, cross-site scripting, SSRF, insecure deserialization, authentication and authorization bypasses, and denial-of-service and DDoS techniques — sufficient to assess real exploitability rather than defer to a scanner score
• • Hands-on proficiency with security testing tooling, including Burp Suite for web application testing and Postman for API testing, along with comparable intercepting proxies and fuzzing tools
• • Working coding ability, primarily Python and shell scripting, sufficient to automate triage and reporting, parse and enrich findings, build integrations between security platforms, and write or adapt proof-of-concept code to validate a finding
• • Hands-on experience securing at least one major cloud platform (AWS, Azure, or GCP), including operating or responding to CSPM tooling
• • Solid understanding of network protocols (TCP/IP, DNS, TLS) and perimeter security technologies
• • Familiarity with security frameworks and standards (NIST CSF, CIS Benchmarks, ISO 27001) and the ability to translate control requirements into actionable technical configurations, including gathering, maintaining, and presenting evidence to support audit and assessment activities
• • Strong written and verbal communication skills, with the ability to translate technical risk for non-technical stakeholders and to hold remediation owners accountable without escalating every disagreement
• • Demonstrated curiosity and speed of learning: a track record of picking up unfamiliar tooling, evaluating new security products, and getting them into production use without extensive hand-holding
• • Interest in applying emerging AI capabilities to security operations, and the judgment to distinguish tooling that meaningfully reduces risk from tooling that only adds noise
• • Sedentary - Exerts up to 30 lbs. of force occasionally and/or a negligible amount of force frequently or constantly lift, carry, push, or pull. Involves sitting most of the time but may involve walking or standing for brief periods of time
• • Experience operating or triaging a public or private bug bounty program on a platform such as HackerOne, Bugcrowd, or Intigriti
• • Offensive security experience: penetration testing, exploit validation, or red-team operations, including familiarity with automated or agentic testing platforms
• • Experience with infrastructure-as-code security (Terraform, CloudFormation) and shift-left security practices
• • Experience securing containerized workloads, including image hardening, registry security, runtime protection, and familiarity with orchestration platforms such as Kubernetes or ECS
• • Experience developing security automation or internal tooling beyond scripting, including work with security platform APIs and CI/CD integrations
• • Exposure to SIEM/SOAR platforms and security telemetry pipelines
• • Familiarity with zero trust network architecture (ZTNA) and micro-segmentation
• • Relevant certifications: AWS Security Specialty, CCSP, CISSP, OSCP, CompTIA Security+, or equivalent
