Senior Software Architect

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 Friends & Family Capital, 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.

• Lead software engineering team, manage software development life cycle, and own sprint planning to ensure implementation goals are met
• Support accreditation, verification, and testing activities in support of testing and operational deployments
• Create and maintain HarborOS technical documentation in compliance with Government standards

What We're Looking For

• Bachelor's or Master's degree in Computer Science, Software Engineering, or a related field
• 5+ years of experience in full-stack software development with proficiency in modern front-end frameworks and backend technologies
• Experience leading software delivery for US Government programs from development to deployment; familiarity with tactical data standards and military C2 ecosystems, such as BATDOK, TAK, JOMIS, GENISIS, T6, Maven, Lattice, and others preferred
• Knowledge of containerization and orchestration, including Kubernetes and Docker in disconnected or edge environments
• Experience with using cloud services such as AWS or Azure
• Knowledge of CI/CD pipelines for building and testing packaged software
• Understanding of defense software development processes and accreditation requirements is a plus
• Understanding of government security practices, including secure coding and system hardening

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.

This role requires the candidate be eligible to obtain and maintain a U.S. security clearance.
