We’re a team of builders, adventurers, and risk takers using technology to help people confidently explore the outdoors. Driven by our mission to awaken the adventurer inside everyone, we build products that optimize every outdoor experience and inspire confidence to get out and go further.
We’re a high-growth tech company. The pace is fast, the work takes grit, and ambiguity is part of the job. As the world changes around us, we adapt - continuously evolving how we build, prioritize, and deliver.
Our business moves quickly, and there’s real opportunity to shape what we build next. Each of our verticals - Hunt, Offroad, Backcountry, and Fish - is at a different stage of maturity, which means the challenges you encounter and the impact you have will vary depending on where you sit and what the business needs most.
We operate with an experimentation mindset, continually iterating and improving how we solve problems. We expect our people to use the latest tooling, including AI, thoughtfully and responsibly, pairing human judgment with technology to increase quality, speed, and impact.
Our impact comes to life through the products we build, in the stories of our customers, and in our growing commitment to land stewardship and recreational access.
onX is seeking a Senior Backend Engineer with a passion for building scalable platform Identity and Access Management (IAM) systems. Your focus will be on designing, developing, and scaling secure authentication, authorization, and user management services that are foundational to our platform.

Space is a warfighting domain. True Anomaly seeks those with the talent and ambition to build the technology that secures it.
OUR MISSION
True Anomaly delivers decisive capabilities for space superiority. We build autonomous spacecraft, advanced payloads, mission software, and space-based interceptors — enabling the U.S. and its Allies to secure the space environment and counter threats from the ultimate high ground.
OUR VALUES
YOUR MISSION
Software is the central nervous system for True Anomaly's engineering and product thesis. Software bridges the gap between military objectives, theoretical astrodynamics and the human and autonomous control of spacecraft and ground systems in time and space. True Anomaly is seeking an exceptional Staff Elixir Software Engineer to lead the technical direction and evolution of our distributed spacecraft ground control system.
This is a high-impact, strategic leadership role. You'll define and drive the backend systems technical roadmap, lead cross-functional initiatives that span engineering, product, and operations, and establish the architectural foundations that will scale our distributed ground control platform for years to come. You'll identify strategic technical investments, champion them across the organization, and lead their execution. You won't just build features; you'll shape the product direction, influence company objectives, and mentor the engineers who will build the next generation of our platform. When you see systemic issues affecting reliability, velocity, or quality, you'll diagnose root causes, build consensus around solutions, and drive organizational change to address them.
You do not need to have experience building space ground systems or experience in aerospace. You'll lead high-priority, greenfield initiatives with strategic importance to the company and a chance to fundamentally impact the outcome of future conflict (and the future of the company), all while enjoying world-class benefits including platinum healthcare, flexible work hours/location, highly competitive compensation and a generous stock options package.

OUR VALUES
YOUR MISSION
As a Staff Security Architect, you will be the critical technical bridge securing True Anomaly's national security space systems with particular emphasis on ground-based command and control (C2) infrastructure, Space Based Interceptors software platforms, and cloud environments operating at DoD Impact Level 5/6 and SECRET/TS/SCI classification levels.
This is a unique, hands-on role that blends deep security architecture expertise with active software development. You will design and implement security architectures spanning the full mission lifecycle including satellite operations, ground segments, C2 systems, and mission planning platforms while supporting the end-to-end journey to Authority to Operate (ATO) across IL-5, IL-6, and TS/SCI environments. You will be responsible for ensuring our systems meet the most rigorous federal security standards while maintaining operational effectiveness in contested environments.
This is an ideal role for a security-focused technologist who can write code, architect secure systems, engage government assessors, and lead cross-functional teams through complex RMF processes.
