Senior Security Engineer

Senior Security Engineer | Fintech | London | £125k + Equity

Are you a security engineer who thrives in fast-moving startups? Do you want to shape security from the ground up at a company that's redefining international payments in Africa? By making payments faster, fairer, and more reliable they're helping to support African SMEs to grow and Thrive.

This Y Combinator-backed fintech has already made history-one of the fastest-ever Series A raises ($20M) and is founded by entrepreneurs who've scaled a unicorn before. Now, they're looking for their first security hire to build and lead security as they scale.

What's in it for you?

✅ First security hire - own and shape security from day one

✅ High-growth fintech - tackling cross-border payments in Africa

✅ Elite backing - YC, Series A, and a founding team with unicorn experience

✅ Autonomy & impact - influence tech, culture, and security strategy

What they need:

🔹 Senior Security Engineer with startup/VC experience

🔹 Hands-on expertise in cloud, app security, and securing financial systems

🔹 Ability to balance security with fast product delivery

🔹 Someone who can build, not just maintain

The role is based in the company's London office and they typically do 3 days a week with some international travel requirements.
