Senior Software Engineer, Platform

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 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. 

Role 

We're looking for a Senior Software Engineer to join our growing Platform team and help us execute on scaling Peregrine's cloud footprint. You'll build and ship initiatives that improve performance and reliability, reduce infrastructure cost, strengthen our security posture, and make the platform more developer-friendly, often all at once. 

This role is hands-on: you'll take ownership of moderately complex infrastructure problems and drive them from design through to production, exercising good judgment about how your work should fit into the broader platform. You'll juggle several priorities without much day-to-day guidance, flag risks and status changes early, and weigh cost and effort tradeoffs when choosing how to implement something. You'll also start lending a hand to less experienced engineers and weighing in on technical decisions beyond your own immediate work. 

Representative problems you'll work on include: standing up new regions and customer environments with minimal manual work as Peregrine's footprint grows; building and shipping autoscaling and right-sizing systems that cut cloud spend without sacrificing headroom; strengthening reliability and incident response for mission-critical services so outages are rare and fast to resolve; hardening platform security controls to meet the compliance bar our public-sector customers require; and building paved-road tooling that lets product teams deploy, observe, and debug their services without needing deep infra expertise. 

About You 

• Tackles moderately complex, well-defined problems independently, and thinks about how the work threads into the wider system 

• Writes clean, well-organized code and knows when to extend an existing pattern rather than build something new 

• Sees a project through from kickoff to done, including chasing down bugs that don't have an obvious root cause 

• Manages several priorities at once without needing much day-to-day direction 

• Surfaces risks and status changes early, and keeps the right people informed 

• Weighs cost, effort, and business impact when choosing how to implement something 

• Starting to mentor other engineers and offer a perspective on technical decisions beyond their own area of ownership 

What We Look For 

• Degree in Computer Science or a related field, or equivalent experience 

• 5+ years of experience building and operating cloud infrastructure at scale, with direct ownership of platform or networking systems 

• Proficiency in a modern programming language commonly used in infrastructure work, such as Python or Go 

• Hands-on experience with major public cloud platforms, container orchestration, and infrastructure-as-code tooling 

• Track record of shipping work that drives 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 

• Located in Washington, DC and open to working in the office 

• You currently hold, or are able to obtain, an active U.S. security clearance (required).
