Staff Software Engineer

Who you are

• 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
• Thrive on ambiguity and enjoy diagnosing hard, high-stakes production problems
• Excellent technical vision, with the ability to turn broad infrastructure goals into a concrete, sequenced roadmap
• 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
• Located in San Francisco, CA and open to working in the office

What the job involves

• 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
• Representative problems you'll work on include: making it possible to stand up new regions and customer environments with minimal manual work as Peregrine's footprint grows; building 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 network and platform security controls to meet the compliance bar our public-sector customers require; building paved-road tooling that lets product teams deploy, observe, and debug their services without needing deep infra expertise; and, as our traffic and capacity needs grow, partnering with our traffic engineering team to help shape technical direction for routing and load balancing at scale
