About this Role The Senior Manager, Security Engineering leads the team that designs, builds, and runs Quanta's security technology. This is a hands-on engineering leadership role. You will own the security platform stack and its integrations, drive the security engineering side of mergers and acquisitions, and set the technical direction your team builds against.

Quanta is large and decentralized, with hundreds of operating companies and tens of thousands of endpoints across corporate and field locations. The role suits an engineer who can standardize, automate, and integrate security across many autonomous business units rather than one uniform estate.

You will lead a small team of security engineers and are expected to understand the major areas of security, including endpoint, network, identity, cloud, vulnerability management, and penetration testing. You will own the ones this role is accountable for, and guide the team and partner with the functions that own the rest. This is an engineering role focused on building and hardening security capability, not a monitoring or on-call operations role.

The role calls for strong hands-on engineering depth alongside the leadership skills to run a team and the communication skills to explain technical risk to executives. What You'll Do Security Platform Engineering •Own the security platform stack end to end. For each platform, design, deploy, configure, tune, upgrade, integrate, and eventually retire it, and keep ownership and documentation current. The stack covers endpoint protection, the SIEM and security data pipeline, security automation, email security, secure web and private access, PAM, and EPM.•Build and maintain the integrations that connect security platforms to one another and to enterprise systems, including API and connector development.•Engineer and enforce cloud security controls on the approved cloud platforms, including guardrails, workload identity, logging, encryption, and prevention of public exposure.•Continuously verify that deployed controls work as designed, and fix what does not.•Lead platform consolidation and migration programs, from selection and parallel run through cutover and decommissioning of legacy tooling. Mergers, Acquisitions, and Integration •Lead the security engineering side of mergers and acquisitions, starting with pre-close technical due diligence of a target's identity, endpoint, network, and cloud posture.• Plan and run post-close integration: onboard acquired environments onto enterprise security tooling and telemetry, consolidate tenants and domains, and sequence remediation of inherited exposure.•Support divestitures and carve-outs, including data segregation, access removal, and telemetry separation.•Standardize security controls across newly acquired and existing operating
