The Role

We are looking for a Product Security Engineer to join the team responsible for securing Action1's multi‑tenant SaaS product.

In this role, you will work closely with engineering, product, and security teams to identify risks early, support vulnerability handling, improve secure development practices, and help make product security practical, clear, and actionable.

This is a hands‑on role for someone who understands both software engineering and cybersecurity, enjoys working directly with developers, and wants to help build security into the product without slowing teams down unnecessarily.

What You'll Do

• Support PSIRT and vulnerability handling activities
• Validate, triage, track, and coordinate security reports
• Provide practical remediation guidance to engineering teams
• Help validate security fixes and reduce product security risks
• Review code, APIs, and architecture to identify security issues early
• Conduct threat modeling and security design reviews
• Improve security automation in engineering workflows
• Support SAST, SCA, secrets scanning, and other security controls
• Maintain SBOMs, dependency visibility, and remediation follow‑up
• Support security assessments, vulnerability assessments, and penetration testing
• Maintain vulnerability handling playbooks, product security procedures, and incident response runbooks

What We're Looking For

• 3+ years of experience in product security, application security, DevSecOps, or a related cybersecurity field
• Strong software engineering background and ability to work effectively with engineering teams
• Understanding of application, API, infrastructure, and software supply chain security risks
• Experience applying cloud security concepts and practices
• Understanding of IAM, network security, logging, monitoring, and secure cloud architecture patterns
• Familiarity with vulnerability management, incident response, security assessments, and secure SDLC practices
• Experience with threat modeling and security design reviews
• Strong communication skills, including professional communication with external researchers and vendors
• Ability to work independently and as part of a team in a fast‑moving environment

Nice to have

• Genuine interest in cybersecurity and motivation to grow as a product security expert
• Hands‑on experience with AWS security controls, best practices, and architecture patterns
• Hands‑on experience with C++ or JavaScript
• Experience with security testing and automation using scripting, APIs, CI/CD pipelines, or specialized tools
• Experience with threat modeling for SaaS, API, cloud, or on‑prem product components
• Experience with SBOM generation, dependency visibility, or software supply chain security

What We Offer

• Fully remote work environment
• Opportunity to work on a real security product used by IT and security teams
• High ownership and direct impact on product security practices
• Close collaboration with engineering, product, and security teams
• Fast‑growing software company with low bureaucracy and practical decision‑making
• Opportunity to improve security processes, automation, and engineering workflows
• Supportive team that values clear thinking, ownership, and continuous learning
