Senior Software Engineer

Peregrine Technologies
San Francisco, CA


Backed by leading investors from Silicon Valley, Peregrine supports public safety agencies across the country — from Los Angeles to Louisville to Atlanta — empowering public servants to improve operations and make better decisions in the moments that matter. Today, our technology is used by customers to serve more than 30 million Americans. We’re motivated to build technologies by partnering with our customers; we listen to their needs, learn from their experiences, and develop effective solutions to help them achieve transformational outcomes. Together, we’re creating safer communities, protecting privacy and civil liberties, and helping everyone in America thrive.


We are a team of public service entrepreneurs who are passionate about solving hard problems. We trust and help each other, and love diving into challenges together. We believe empathy, curiosity, integrity, courage, and excellent execution are key to building impactful software. If mission-focused work is your north star, come build with us. We’re just getting started.


Our Team

As an engineering team, we believe strongly that empathy improves our solutions. Seeing how people use the product is a priority and the way we get to the right answer. Engineers will have the opportunity to work closely with our team onsite to understand the variety of use cases that Peregrine serves.

We’re looking for a Senior Software Engineer to join our core engineering teams. You’ll work cross-functionally with design and product management to build systems that are robust, scalable, and user-centered. Our teams tackle a range of challenges, from enabling real-time user collaboration on detailed maps to building high-scale backend architecture for ingesting billions of data points.

We value both ownership and collaboration—you will take full responsibility for major features and work closely with other engineers to drive them to completion. We believe that humility and empathy are essential for building the right solutions—you will collaborate directly with our deployment team and users as we iterate to solve their problems. Perseverance and creativity are crucial to executing our vision.

Role


We are looking for strong developers to join our small but growing team. As a Senior Software Engineer, you’ll have vast ownership across our stacks, making decisions that will have an outsized impact for years to come.

You’ll take on some of our most complex challenges—like designing scalable permission systems to manage access to terabytes of data across thousands of organizations. You’ll help build intuitive controls that let organizations decide what data to share, when to share it, and with whom. You’ll also architect frameworks for secure collaboration, enabling seamless partnerships while maintaining data sovereignty and compliance. And you’ll create advanced sharing mechanisms that strike the right balance between openness and security to unlock the full potential of cross-organizational collaboration.

Our stack is constantly evolving but based on a backend foundation of Python, Django, Celery, Airflow, and Kafka; a frontend built in React, Redux, and Mapbox; data stores including PostgreSQL and Elasticsearch; machine learning models hosted in Bedrock and Sagemaker; and with AWS, Pulumi, Terraform, and Kubernetes as our underlying infrastructure.

About you

  • Desire and drive to own large portions of the application from start to finish

  • Passion for crafting and shipping software solutions that delight users

  • Thrive on ambiguity and love taking on hard problems

  • Excellent technical vision with the ability to synthesize product requests into strong and reliable software components

What we look for

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

  • 4+ years of experience working with cross-functional software development teams

  • Experience shipping and iterating on production-grade software components professionally and / or in the open-source community

  • Ability to write robust, well tested, and well-designed code that frequently gets deployed to users

  • Solid understanding of architecting and scaling distributed software systems

  • Strong best practices in modern software development and comfort navigating large codebases

  • Located in San Francisco and open to working in office



Salary Range: $130,000 - $250,000 Annually + Benefits + Equity (if applicable) + Bonus (if applicable)
