Job description

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.

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.

The Platform team consists of detail‑oriented engineers who drive innovation, enhance performance through technical excellence, and focus on results. We own the performance of Peregrine’s mission‑critical infrastructure as well as the high‑risk, platform‑spanning initiatives that create unmatched new capabilities.

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 experienced software engineers to join our growing platform team. As a Software Engineer on the platform team you’ll have vast ownership across our stacks, making decisions that will have an outsized impact for years to come.

You’ll push the boundaries of what a data platform can do by creating novel capabilities that span the platform and optimizing subsystems to achieve order‑of‑magnitude improvements in performance. You will work on projects such as re‑architecting our Elasticsearch cluster, taking response times from seconds to milliseconds; and owning other strategic initiatives that deliver industry‑leading platform performance and capabilities.

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
• 2–5 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
• Strong understanding of product development and navigating large codebases
• Located in San Francisco and open to working in office
