Role overview
Job description
About the role Zenskar is a multi-tenant billing and revenue platform. We hold our customers' contracts, invoices and usage data, along with their credentials to Stripe, QuickBooks and other systems. Every enterprise buyer asks the same question: can we trust you with this? You will be our first dedicated security engineer, accountable for three questions: is this system safe to hand a customer's revenue data to, would we know if it wasn't, and can we prove it to an auditor or enterprise buyer without inventing anything? It's a hands-on individual contributor role. Your Manager reviews your work. What you'll do Threat-model new features before code exists: webhooks, integrations, AI agents acting on customer data. Find real, exploitable bugs in our code (authorisation, IDOR, injection, SSRF, races on money paths), prove them, and fix the class of bug. Treat tenant isolation as a property
