Senior Security Engineer
About Pave Bank
Pave Bank is the world’s first programmable business bank. Built by the founders behind Monzo and BigPay, we’re redefining global business banking by combining programmable financial infrastructure with world-class client experiences.
About the Role
Pave Bank is building the next generation of programmable banking infrastructure. We’re looking for a Senior Security Engineer who is independent, curious, and has a hacker mindset — someone who thinks like an attacker to keep our platform secure.
In this role, you will be a critical guardian of Pave Bank, identifying weaknesses, closing loopholes, and empowering our Product and Engineering teams to build and ship quickly without compromising security.
What You'll Do
Review Pave Bank’s platform and product code to identify security issues and guide engineers toward secure solutions.
Educate engineering and product teams on secure coding and design practices, and why they matter.
Write and contribute to internal tools, libraries, and automation to improve security testing and enforcement.
Continuously test internal and external applications for vulnerabilities.
Stay current on the latest threats and attack techniques, and how they apply to our systems.
Assist with third-party application security reviews and penetration tests.
What You’ll Bring
An adversary-first mindset when approaching software development
Passion for solving complex security challenges in high-growth startup environments.
Self-motivation and a desire to keep learning and improving.
Strong understanding of attacker tools and techniques, and how insecure development practices can be exploited.
Programming experience in at least one modern language, such as Go, Python, or TypeScript.
Clear communication skills, with the ability to explain security concepts to both technical and non-technical audiences.
General understanding of blockchain technologies and cryptocurrency systems, and their unique security implications.
Nice to Have
Experience writing secure backend code in Go.
Familiarity with frontend security concerns in TypeScript-based SPAs.
Understanding of common authentication and authorization patterns (e.g., OAuth2, Google Zanzibar, RBAC).
Experience working in security within a fast-paced startup or fintech environment.
Exposure to smart contract or Web3 security concepts.
