ABOUT NORTHWOODNorthwood is deploying a global network of phased array ground stations that will fundamentally change how satellites communicate with Earth. These systems support real-time, high-throughput communications that commercial and government customers rely on for mission-critical operations.Role OverviewAs Product Security Lead, you will own the security of Northwood's software and systems from design through deployment. This is a senior technical leadership role for an engineer with deep expertise across the full product security lifecycle — from threat modeling and secure architecture review to penetration testing, vulnerability management, and the cryptographic foundations that protect mission-critical space communications.You will embed security into every stage of our software development lifecycle, build and mature our application security program, and ensure that the products Northwood delivers to government and commercial customers meet the most demanding security requirements in the industry. This role partners closely with product and infrastructure engineering teams and reports to the Head of Security.ResponsibilitiesApplication Security & SDLCOwn application security across the full software development lifecycle, ensuring security requirements are defined, validated, and enforced from design through production release.Conduct security architecture reviews and threat modeling for new product features, platform changes, and third-party integrations.Establish and maintain secure coding standards, security review gates, and developer security training programs.Serve as the primary security liaison for product engineering teams, translating compliance and security requirements into actionable engineering guidance.SAST, DAST & Vulnerability ManagementDeploy, manage, and continuously improve static application security testing (SAST) and dynamic application security testing (DAST) tooling integrated into development workflows.Own the vulnerability management program end-to-end: discovery, triage, prioritization, remediation tracking, and reporting across product and infrastructure systems.Conduct and coordinate penetration testing against Northwood's products and infrastructure, including scoping, execution, findings management, and remediation validation.Build and maintain container security scanning, dependency analysis, and software composition analysis (SCA) pipelines.CI/CD Security & Secrets ManagementIntegrate automated security validation and policy enforcement into CI/CD pipelines, ensuring security controls do not impede engineering velocity.Own secrets management infrastructure, including deployment, policy configuration, access controls, and audit logging for platforms such as HashiCorp Vault.Implement and enforce controls for secure artifact management, signing, and supply chain integrity across build and deployment pipelines.Review and harden Infrastructure as Code, GitOps workflows, and deployment automation for security misconfigurations and policy violations.Cryptography & Secure CommunicationsDesign and implement cryptographic controls for data at rest, data in transit, and satellite communication protocols, ensuring alignment with NIST standards and government customer requirements.Evaluate and advise on cryptographic library selection, key management architecture, and certificate lifecycle management.Identify and remediate cryptographic weaknesses across product systems, including legacy protocol usage, weak cipher configurations, and improper key handling.Team Leadership & Cross-Functional CollaborationHire and develop product security engineers as the team scales.Collaborate with network operations, mission management, and compliance teams to maintain a security posture that enables mission success without breaking deployment cycles.Build security documentation, audit evidence, and reporting standards that satisfy FedRAMP, CMMC, and NIST 800-171 requirements.Basic Qualifications5+ years in product security, application security, or a closely related security engineering discipline, with demonstrated technical leadership experience.Deep expertise in SAST and DAST tooling, including tool selection, integration into CI/CD pipelines, and results-driven vulnerability remediation programs.Hands-on experience conducting or coordinating penetration testing engagements, including scoping, execution, and remediation validation.Strong applied cryptography knowledge, including symmetric and asymmetric encryption, PKI, key management, and secure protocol design.Experience owning vulnerability management programs, including prioritization frameworks, SLA enforcement, and executive reporting.Proficiency with secrets management platforms such as HashiCorp Vault, including policy design and access control architecture.Experience securing CI/CD pipelines and GitOps workflows, including IaC security review and automated security gate implementation.Proficiency in one or more general-purpose programming languages (Python, Go, Rust, or equivalent).Familiarity with government compliance frameworks including NIST 800-171, CMMC, and FedRAMP.Ability to obtain and maintain a TS/SCI clearance.U.S. citizenship or status as a lawful permanent resident required to conform with ITAR export regulations.Preferred QualificationsActive TS clearance or higher.Experience with HashiCorp Vault, Terraform, and ArgoCD in production environments.Hands-on experience with container security scanning, admission controllers, and microservices security patterns.Familiarity with software supply chain security frameworks and tooling (SLSA, Sigstore, SBOM generation).Background in aerospace, defense, critical infrastructure, or other regulated industries.Experience with DFARS compliance, ITAR, and government contracting security requirements.Familiarity with eMASS or similar government assessment and authorization tools.CISSP, CSSLP, OSCP, or equivalent professional certification.
