Watch our showcase > Read up on our $100m Series C Learn more about our culture > Which team will you be joining? You’ll be joining the ProdSec/AppSec team to help build the entire product security surface for a company processing payments at scale: threat modelling, security review, compliance, incident escalation, and the multi-year AppSec roadmap. You'd be the second hire, and the person that function finally gets to share the work with. This is a hands-on delivery role, and a genuinely formative one. You’ll help set the security strategy and architecture; you take real ownership of the work that turns it into reality, reviews, research, automation, and the day-to-day partnership with engineering teams. You'll have a clear direction to work within and someone senior to learn from, while still owning your projects end to end. Security at Primer sits close to the engineering teams it protects rather than off to one side, so you'll spend real time embedded with the people building Cloud, Infra, and product. For someone who wants to go deep in product security with room to grow, there are few better seats than being the second engineer in a function that's only now scaling. What will you be doing? Running security reviews and threat modelling on features and systems across Primer's product, and turning findings into clear, actionable guidance for the teams shipping them Independently planning and delivering your own security projects, from initial design through to rollout Building tooling and automation that makes future reviews faster and cheaper to run Coordinating penetration
