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.
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.
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
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
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
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
