Security Engineer - Product

Cardless is the infrastructure that lets consumer brands put credit cards directly in their own product. Instead of sending customers off to a bank’s website to manage their card, our platform handles the credit program end-to-end (applications, underwriting, servicing, rewards, compliance), so brands can build the card experience inside their own ecosystem. We power programs for Coinbase, Bilt, Qatar Airways, Alibaba, and others. We’ve raised $170M to date, most recently a $60M Series C led by Spark Capital.

We’re hiring a Product Security Lead to drive how we build security into the platform. The work spans authentication, authorization, anti-abuse controls, in-product fraud primitives, and the secure‑by‑design practices that come with running credit infrastructure for partners of this caliber. The role is hands‑on and deeply cross‑functional, working with Engineering, Risk, Compliance, Legal, and Data. You’ll report to the Head of Engineering.
