Job description

Full Stack Developer - MERN Stack

Relativity, Inc. | Lakeway / Austin, TX | Full-Time, In Office

Relativity is hiring two full-time Full Stack Developers to work alongside our Development Team on secure, mission-critical software for public safety, government, and military-focused customers.

We build modern applications involving secure data sharing, analytics, operational workflows, dashboards, and web-based tools for agencies that need reliable technology.

We are looking for high-upside developers with strong MERN stack ability, sharp problem-solving skills, and the drive to grow fast in a serious software environment.

This is not a role for someone who wants to coast, wait for perfect instructions, or be managed every step of the way. We want builders with high agency, technical curiosity, strong execution speed, and the ability to take ownership.

What We’re Looking For

  • MERN stack experience: MongoDB, Express, React, Node.js
  • JavaScript / TypeScript experience
  • Ability to work across frontend and backend
  • Strong technical fundamentals and systems thinking
  • High ownership and ability to solve problems end-to-end
  • Fast learner with intellectual humility
  • Clean, practical, maintainable coding habits
  • Strong attention to detail
  • Grit under pressure
  • Interest in public safety, government, military, or defense-style technology
  • Ability to understand the real-world operators who use the software
  • Confidence to challenge assumptions and contribute ideas

We are open to candidates with roughly 1–5 years of real development experience. One role is better suited for a stronger mid-level developer who can bring technical depth. The other is better suited for an early-career developer who is hungry, capable, and ready to figure things out fast.

Requirements

  • Must be a U.S. citizen
  • Must be local to the Austin / Lakeway, TX area
  • Must work full-time from our office
  • No hybrid or remote applicants will be considered
  • Must be able to pass a background check
  • Must be able to pass a drug test

If you want responsibility early, like moving fast, and want to build serious software for serious users, we want to talk.

Company Description

Relativity, Inc. has been developing software solutions for 28 years, specifically tailored to the unique needs of law enforcement, public safety, and military agencies. Our goal is to empower those who serve others by delivering innovative, real-time, cloud-based technology. We focus on enabling full-circle management of information from inception to completion.
