Job summary

Gemini is seeking a Senior Manager, Platform Security to lead a cloud-native security team responsible for secure-by-design architectures, IaC, and security tooling. The role blends hands-on coding with strategic leadership to enable engineering partners and drive security maturity.

Based in New York, NY, you will write Terraform, review PRs, mentor engineers, and align security initiatives with business goals.

Qualifications

• 5+ years of leadership experience for cloud-native engineering and/or security teams, with a strong preference for AWS-based organizations.
• 10+ years of direct, technical experience in relevant roles (e.g., Platform Engineering, Security), with continued hands-on coding/IaC work within the last 2-3 years — not solely past practitioner experience
• Strong experience in AWS, EKS (Kubernetes), IAM, Terraform, GitHub Enterprise Cloud
• Experience leveraging industry security frameworks & standards that act as the basis of maturing the overall security program and enable successful business outcomes
• Comfortable with hiring & scaling a team
• Prior success in leading a team through organizational change management, with a strong preference for start‑up experience in a technology-centric business
• Able to easily communicate with technical stakeholders at their level, hearing their feedback and translating those needs or concerns into program‑level outcomes
• Pragmatic about security requirements, ignoring “best practices” that don’t make sense to the needs of the business by leveraging your team’s expertise for decision making
• Strong written and verbal communication skills with an attention to detail

Responsibilities

• Provide strategic and technical leadership of Gemini's Platform Security team, personally architecting and implementing security solutions alongside engineers — including writing and reviewing Terraform, CI/CD pipelines, and security tooling code
• Align team-wide strategy with the needs of the business, internal partners, & peer Security leadership
• Enable the ongoing success & growth of the team through creation of hiring plans and hands‑on technical mentorship — pairing with engineers, reviewing designs and PRs, and staying current on the team's actual codebase
• Establish a Platform Security roadmap for initiatives that will provide ever-increasing maturity of capabilities for stakeholders, while also reducing toil through automation
• Serve as a senior technical escalation point for the team's hardest architecture and engineering problems, contributing working code/IaC when the situation calls for it
• Foster trust-centric relationships with key partner teams, ensuring that their voices are heard and needs are being met, while achieving excellent security outcomes together
• Lead the development of security policies, procedures, standards, & guidelines that will guide functional security outcomes with all GRC and Audits needs being met
• Determine program KPIs that will meaningfully highlight where we’re succeeding, or falling short of, the mission we aim to accomplish for the business
• Provide guidance through lived‑experience and industry awareness on the different approaches to architecture, security engineering, and business‑achievement goals
• Define a customer‑first process, choosing to provide self‑service solutions that minimize friction, create agility, and provide value‑oriented ways to solve problems
• Manage relevant third‑party vendor relationships, leading the determination of when & why to “build” vs. “buy” in response to gaps in capabilities the business may have
