There are too many problems that are unaddressed in the resiliency ecosystem. These problems, while quiet, are significant; and left unsolved they create gaps that widen until systems crack and missions stall.

Valinor is a new type of defense and government tech company focused on solving the problems others don’t. Our unique model of centralized go-to-market and decentralized engineering allows us to move with unparalleled efficiency to identify unmet needs, build right-sized solutions, and get products where they matter most - in the hands of users. Unlike others in the space, who focus on the flashy problems, Valinor exists to solve the quiet, unaddressed problems–the small but significant ones that lead to cracks in the country’s strength, stability, and security.

Backed by General Catalyst, Founders Fund, and Red Cell Partners, Valinor was founded in 2024 and has established strategic partnerships with Palantir, Anduril, and Helsing. We are building the dream team, and we want you on it.

Strong DevOps instincts and a systems-thinking approach
Willing to travel and collaborate hands-on
Preferred: Experience in healthcare or DoD environments

What Valinor offers

Competitive salary, equity packages, and benefits, including health, dental, and vision insurance - fully covered for employees, 401K, development stipends, among others.
Unlimited PTO and two-week company holiday at the end of every calendar year.
We are a pro-mental health and pro-family company - we actually encourage employees to spend time with themselves and their families. Valinor also provides fertility benefits to those just beginning that journey.
Fun work environment - we like to laugh and take care of each other, but we also deeply respect the mission in front of us.
Headquartered in Washington DC with additional coworking spaces throughout the country. We also host team offsites and colocations around the U.S.
