About the Role

Product Security is responsible for ensuring the continuous security of Harness customer-facing products and internal tools.  The team is focused on proactively discovering security weaknesses, driving and advising risk remediation, building a paved road for developers to adopt secure development practices, and developing partnerships with engineering and product teams to accelerate the release of software with security by design.

The Senior Product Security Engineer is a highly skilled practitioner who drives hands-on security work across the Harness platform. You will own technical security initiatives end-to-end, partner closely with engineering and product teams to identify and remediate vulnerabilities, and build tooling and processes that elevate the security bar across our development lifecycle. This role is for engineers who love to build, break, and secure complex systems.

What You Will Do

• Design and develop product security APIs, tools, and utilities for internal and external stakeholders.
• Conduct threat modeling and secure design reviews for application backend services and business integrations.
• Perform advanced penetration tests and adversarial attack simulations against Harness modules, APIs, and codebase using industry-standard frameworks.
• Lead manual and automated code review efforts to discover vulnerabilities, weaknesses, and anti-patterns in the Harness platform.
• Implement and operate security tooling including SAST, DAST, and SCA, and integrate these into CI/CD pipelines.
• Consult and advise developers and Product Managers on security standards, vulnerability remediation, and security architecture.
• Assess risks and trade-offs, and propose solutions for product security features such as authentication and authorization.
• Participate in the creation, review, and implementation of technical security standards across global engineering teams.
• Use the Harness platform to integrate security processes like vulnerability management into the SDLC.
• Collaborate cross-functionally with Engineering and Product to accelerate the release of software with security by design.
