Luckily, our people are the best. Join us!  How do we work? We believe that security shouldn't be a bottleneck or an afterthought - we bake it directly into everything we build. As a team, we operate on a "push security left" philosophy, meaning we collaborate deeply with our engineering and product teams early in the development lifecycle rather than checking things at the very end. We value cross-functional flexibility, strong defense-in-depth principles, and continuous automation. On any given week, you might find yourself switching gears from cloud hardening and writing infrastructure-as-code to reviewing application vulnerability fixes, advising on secure AI governance, or mentoring engineers. We foster an open, supportive culture where diverse technical opinions are brought together to solve complex problems, and where we actively invest in our people's professional growth and industry presence. In this role, you will: Lead & Mentor: Manage and guide a talented Security Engineering team, organizing work processes, tracking strategic goals, and actively mentoring team members to level up their technical and professional skills. Build Secure Software: Directly design and build security-critical features (like authentication, authorization, 2FA, and transaction integrity components), and navigate security pitfalls across various languages like Go, Python, JS, C++, and Java. Champion DevSecOps & AI Security: Scale our impact by embedding automated security tools (SAST, DAST, SCA, Secrets, fuzzing) into our CI/CD pipelines, and establish security gates and governance for the safe deployment of AI technologies. Implement Defense-in-Depth: Harden environments across both on-premise and cloud-native infrastructure—including databases, networks, Docker containers, and Kubernetes clusters. Make Security Accessible: Instrument and share meaningful security metrics with business stakeholders, and automate workflows (e.g., via ChatOps) to make proactive security practical and visible for everyone. Assess Risk & Drive Strategy: Author security standards, collaborate with Security Operations to stay ahead of upcoming threats, and maintain top-tier cryptographic and secrets management practices. Grow the Team: Contribute to defining talent needs, resource planning, reviewing resumes, and shaping our engineering interview process. What skillset do you need to be successful in this role? 5+ years of solid experience rooted in core engineering principles and…
