  2025-10-08     Peregrine     San Francisco,CA  
Description:

Join to apply for the Senior Software Engineer role at Peregrine. Peregrine supports public safety agencies across the country, empowering public servants to improve operations and make better decisions. Today, our technology is used by customers to serve more than 30 million Americans.

We are a team of public service entrepreneurs who are passionate about solving hard problems. We believe empathy, curiosity, integrity, courage, and excellent execution are key to building impactful software.

Our Team
As an engineering team, we believe strongly that empathy improves our solutions. 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.

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.

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

Peregrine Technologies is committed to creating an inclusive environment for all employees. We celebrate diversity and are a proud equal opportunity employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, gender, gender identity or expression, sexual orientation, national origin, genetics, disability, age, or veteran status.
