About The Position

A new space race has begun. True Anomaly seeks those with the talent and ambition to build innovative technology that solves the next generation of engineering, manufacturing, and operational challenges for space security and sustainability. OUR MISSION The peaceful use of space is essential for continued prosperity on Earth—from communications and finance to navigation and logistics. True Anomaly builds innovative technology at the intersection of spacecraft, software, and AI to enhance the capabilities of the U.S., its allies, and commercial partners. We safeguard global security by ensuring space access and sustainability for all. OUR VALUES Be the offset. We create asymmetric advantages with creativity and ingenuity What would it take? We challenge assumptions to deliver ambitious results It’s the people. Our team is our competitive advantage and we are better together 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 a dedicated Front End Software Engineer to contribute to the continuing evolution of our complex spacecraft modeling and simulation software. This is a high-autonomy, high-accountability role. You'll own entire feature domains from conception to production, drive architectural decisions that affect the entire frontend surface, and set the standard for code quality that junior and mid-level engineers will follow. You won't wait to be assigned work, you'll identify what needs to be done, propose solutions, and drive them to completion. When you see tech debt, you'll flag it, scope it, and champion the work to address it. When patterns aren't serving us, you'll propose better ones and lead their adoption. You do not need to have experience building space ground systems or experience in aerospace. You’ll have ownership of challenging, greenfield problems 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.

Responsibilities

Own and deliver complex 2D and 3D web-based frontend features end-to-end, from technical design through production deployment and iteration
Drive architectural direction for frontend systems, establishing patterns and conventions that scale across the team and codebase
Proactively identify and address technical debt, performance bottlenecks, and opportunities for refactoring
Set the quality bar through rigorous code review, championing testing practices, and writing code that serves as a reference implementation for the team
Mentor and elevate junior and mid-level engineers through pairing, design discussions, and constructive code review that teaches, not just approves
Collaborate as a technical partner with product, design, backend engineers, QA, space operators, and astrodynamics algorithm engineers—contributing to system-wide architectural decisions
Ship efficiently and iteratively, breaking complex work into well-scoped increments while maintaining a bias toward completion over perfection
Document decisions and patterns, ensuring the team's collective knowledge grows and onboarding becomes easier over time
