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.

Team

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.

The Apps team consists of product-oriented engineers with an ethos to develop rich capabilities via thoughtfully designed UX. We build a comprehensive platform that enables users to make mission-critical decisions. Our search, investigative, and analytical applications include maps, networks, charts, dashboards, and more.

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 a developer to expand our mobile offering into a best-in-class app. As one of our first dedicated mobile engineers, you'll take ownership of the mobile product—overseeing the technical architecture and ensuring its scalability and performance. Your decisions will have an outsized impact for years to come. The challenges you’ll take on include:

  • Ensuring cross-platform interoperability
  • Enabling interactive, performant maps with hundreds of thousands of data points
  • Streamlining the ability for users to access their most important information quickly

Our mobile stack includes React Native, TypeScript, Expo, and Mapbox.

About you

  • Desire and drive to own large portions of the application from start to finish
  • Thrive on ambiguity and love taking on hard problems
  • Passion for crafting and shipping software solutions that delight users
  • Ability to raise the bar for and accelerate the development of the mobile application
  • 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
  • 5+ years of experience working with cross-functional software development teams
  • Extensive experience applying best practices to build robust mobile applications with React Native
  • Proficiency in TypeScript and related frameworks
  • San Francisco or Washington DC based candidates strongly preferred (hybrid work is acceptable)

Salary Range: $130,000 - $225,000 Annually + Benefits + Equity (if applicable) + Bonus (if applicable)

Actual compensation is influenced by a wide array of factors including but not limited to skill set, level of experience, certifications or licenses, and specific work location. Information on the benefits offered is here.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
