Senior Software Engineer, Product Platform

At Vanta, our mission is to help businesses earn and prove trust. We believe that security should be monitored and verified continuously, and we empower companies to practice better security and prove it with ease. Vanta has a kind and talented team, and while some have prior security experience, many have been successful at Vanta without it. We are looking for a Senior Software Engineer to join our Product Platform org - the group that powers product development across Vanta by building the shared foundations that every engineering team builds on top of. This hire will join one of two closely-aligned teams within the org, each working on foundational challenges with company-wide impact. Application Primitives is responsible for the shared, customer-facing platform components that product teams implement across the product: examples include comments, notifications platform, event log infrastructure, and agentic audit trails. This team sits at the intersection of platform and product - not pure infrastructure, not pure product - building the reusable building blocks that let other teams ship faster and more consistently. Libraries & Foundations is a brand-new team that owns Vanta's internal engineering libraries and golden-path patterns. Sitting between core platform and product platform in the stack, this team builds the TypeScript-first abstractions and shared foundations that all Vanta engineers build on top of - including event-driven architecture libraries, code quality tooling, and test frameworks. You'll be evaluated for both teams based on your background and interests, and the decision on team placement will reflect where your skills and passions are the strongest fit.
