About The Position

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. 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 when it's working and clearly communicated when it isn'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. We're looking for a Staff Software Engineer to join our growing Platform team and lead the technical strategy for scaling Peregrine's cloud footprint. You'll drive initiatives that improve performance and reliability, reduce infrastructure cost, strengthen our security posture, and make the platform more developer-friendly, often all at once. We're open to leveling this role up to Principal based on your experience and scope of impact. This role blends hands-on technical leadership with cross-functional influence. You'll partner with product engineering teams to understand where infrastructure is a bottleneck, and set technical direction that the rest of the team executes against. As the platform scales, you'll also provide technical guidance to our traffic engineering team. You'll also mentor engineers, review designs, and help build a culture of ownership and operational excellence.

Requirements

Degree in Computer Science or a related field, or equivalent experience
8+ years of experience building and operating cloud infrastructure at scale, with direct ownership of platform, networking, or traffic systems
Hands-on experience with major public cloud platforms, container orchestration, and infrastructure-as-code tooling
Working knowledge of traffic engineering concepts (load balancing, service mesh, autoscaling, CDN/edge routing, capacity planning) to collaborate effectively with our traffic engineering team
Track record of driving down cloud costs through architecture and tooling, without compromising reliability
Solid grounding in cloud and network security best practices, and experience working within compliance-driven environments
Strong instincts for developer experience: building tools, guardrails, and documentation that make the platform easy and safe to use
Comfort operating and improving systems under real production load, including on-call ownership and incident response

Nice To Haves

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
