• 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
