About Peregrine

At Peregrine, we create technology to help governments transform the way they fight crime while building trust with their communities. We do this through openness, accountability, careful policy enforcement, and respect for people’s personal freedoms. 

Our platform fuses disconnected, unstructured data across secure networks and empowers users with highly intuitive interfaces to search, analyze, and collaborate. Customers tell us we help them solve cases that they thought were unsolvable, and allow them to communicate in ways they have never seen before. We are particularly proud to help government agencies solve more crimes while averting wrongful arrests. 

Peregrine has been used to protect children and victims of human trafficking, diffuse organized crime networks, de-escalate hostage scenarios, solve homicide cases, identify serial burglary suspects, and more. Customers use the same platform to facilitate Freedom of Information responses, provide targeted social services for homeless populations, and share data with their community. 

We believe careful deployment of modern technology to solve hard problems in government will create extraordinary positive change for our society, and we seek teammates who want to be part of our mission. 

Our Team

We are a team of principled and curious entrepreneurs who are motivated by solving hard problems. We trust each other, help each other, and love diving into challenges together. We believe perseverance, curiosity, creativity, humble ethos, and world-class execution are key ingredients to building impactful software. 

We are inspired to work hand-in-hand with public servants. Our customers are our partners; we listen to their needs, learn from their experiences, and develop effective software experiences to help them do their best work. 

Our team is advised by leading experts and industry practitioners in the law enforcement, intelligence, and civil liberties sectors who help us develop technology that is both operationally effective and trust-enhancing. We believe data can be used to empower all members of society, whether they are officers, detectives, agents, attorneys, or citizens. 

The Full Stack Software Engineer Role

We are looking for strong developers to join our small but growing team. As one of the earliest engineering hires, you’ll take on a lead role with vast ownership across one of our stacks.  We are tackling challenging and important problems, and need engineers who can operate well in ambiguity and come to a great solution. 

As an engineering team, we believe strongly that empathy improves our solutions. Seeing 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 value strong ownership on our team, while also being highly collaborative and always seeking input and feedback. 

As a full stack engineer you’ll use a variety of programming languages and technologies to scale our platform to handle terabytes of data being ingested across a variety of data sources.  You will own projects from pixels to database queries. Our stack is constantly evolving but based on a backend foundation of Python, Django, Celery, and Airflow, a frontend built in React, Redux, D3, Mapbox, and Blueprint.js, data stores including PostgreSQL, Elasticsearch, and Neo4J, with AWS, Terraform, and Ansible underlying our infrastructure.
