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
We’re looking for a Junior Security Engineer who is independent, curious, and has an adversary first mindset - someone who thinks like an attacker to keep our platform secure.
You’ll be a critical guardian of Pave Bank: identifying weaknesses, closing loopholes, and empowering our Product and Engineering teams to ship quickly without compromising security.
You’ll get hands-on exposure across the full security lifecycle - from code review to penetration testing - with mentorship from experienced engineers.
What You’ll Do
•
Review platform and product code to identify security issues and guide engineers toward secure solutions
•
Build internal tools, libraries, and automation to improve security testing and enforcement
•
Continuously test internal and external applications for vulnerabilities
•
Support third-party application security reviews and penetration tests
•
Help educate engineering and product teams on secure coding and design practices
•
Stay current on emerging threats and attack techniques, and assess how they apply to our systems
What We’re Looking For
Must have
•
An adversary-first mindset - you instinctively ask “how would I break this?”
•
Familiarity with common attacker tools and techniques, and how insecure development practices get exploited (e.g. OWASP Top 10)
•
Programming experience in at least one modern language (Go, Python, or TypeScript).
•
Clear communication skills - you can explain security concepts to technical and non-technical audiences alike.
•
Self-motivation and a genuine drive to keep learning
Nice to have:
•
Exposure to blockchain technologies and cryptocurrency systems, and their security implications
•
Experience with security tooling, CTFs, bug bounties, or open-source security contributions
•
Prior internship or work experience in a fast-moving startup environment
Why Join Us
•
We recently raised a $39M Series A led by Accel, positioning us for major growth — a rare chance to join while things are still moving fast
•
We’re building a fully-licensed programmable bank, rearchitecting how money moves between businesses, across borders, and between traditional and digital finance
•
We ship fast, think deeply, and expect high ownership — your work will hit production quickly across several parts of the business
•
You’ll work alongside engineers from Monzo, Atom Bank, Blockdaemon, GXS, and Grab
