Senior Product Security Engineer — Remote & Equity

primer.io, a remote-first payments infrastructure, is hiring a ProdSec/AppSec engineer to join as the second security hire. You’ll help shape the security surface for a payments platform at scale, performing threat modelling, security reviews, and compliance work with SOC2/PCI.

You’ll embed with engineering teams, own projects end to end, build small tools and automation, and communicate clearly with non‑security colleagues. This hands‑on role offers real ownership and growth as Primer scales.
