Senior Software Security Engineer

Join Fieldguide as a Senior Software Security Engineer, where you'll play a crucial role in building and maintaining our security function from the ground up. You'll work closely with engineering teams to identify and mitigate risks, build secure frameworks and libraries, and enhance our cloud security controls. This hands-on engineering role requires a strong background in software engineering and a passion for security.

• Collaborer avec les équipes d'ingénierie pour identifier les risques majeurs dans un système avant son lancement et construire des cadres et des bibliothèques sécurisés.
• Construire et maintenir des systèmes de gestion des identités et des secrets, y compris l'émission, la rotation et l'authentification des charges de travail.
• Renforcer les contrôles de sécurité de notre cloud et contribuer à la gestion continue de la posture de sécurité du cloud.

• You’ve led a security initiative from design through adoption, and you can point to engineers who are safer and faster because of it
• You reason clearly about trust boundaries and threat models to prioritize risk
• You’re familiar with Kubernetes security primitives, including RBAC, namespaces, network policies, and admission controllers
• You have 5+ years of software engineering experience building and maintaining security-relevant systems in production
• You thrive on breadth, ambiguity, and evolving priorities rather than a single narrow lane
• You have hands-on experience with identity and secrets management, including protocols such as OAuth 2.0 and OIDC
• Experience with developer security tooling such as SAST, dependency scanning, or secure build infrastructure
• Experience with SAML or SPIFFE/SPIRE, or building workload authentication systems from scratch
• Experience securing LLM-based or agentic systems
