Job description

Backed by leading Silicon Valley investors, Peregrine helps public safety organizations, state and local and governments, federal agencies , and private-sector institutions address society’s challenges with unprecedented speed and accuracy. Our AI-enabled platform turns siloed and disconnected data into operational intelligence — instantly surfacing mission‑critical information to empower better, faster decisions that improve outcomes at every touchpoint. Today Peregrine supports hundreds of customers across 30+ states and two countries, serving more than 125 million people — and we’re amplifying our impact as we expand into the enterprise and internationally.

Our Team

The Platform team owns the foundation that every product team at Peregrine builds on. Our job is to make Peregrine's infrastructure fast, resilient, secure, and cost‑efficient, while making it easy for other engineers to ship safely and quickly on top of it. We work closely with our traffic engineering team to keep routing, load balancing, and capacity running smoothly as we scale.

We believe great infrastructure is invisible whenit'sworking and clearly communicated when itisn't. We hold ourselves to a high bar on reliability and security, and we treat other engineering teams as our customers, investing in tooling, documentation, and self‑service paths that reduce their toil.

About You

• Desire and drive to own large, ambiguous infrastructure problems from design through operation
• Passion for building platforms that make other engineers faster and more confident
• Deep interest in the tradeoffs between performance, reliability, cost, and security,and comfort making explicit decisions among them
