Full Job Description

Senior Software Engineer

Defense-Grade AI SystemsRemote (US Only) | Must Be Eligible for Security Clearance (US Residency Required)

Compensation Range: $150,000 - $220,000

About the Role

We are building defense-grade, production-ready AI systems that solve real national security problems at scale. This is not a DevOps role and not a maintenance role. This is a hands-on engineering position for senior builders who want to design, ship, and evolve high-impact software used by hundreds or thousands of users.

You will work on a mix of new IRAD initiatives and existing products, contributing directly to architecture decisions, feature development, and modernization efforts. We are assembling a small, elite engineering team and are intentional about who joins it.

If you are a senior engineer who thrives in environments where you build new things that make a real world impact, take extreme ownership of your craft and strive for continuous growth, this role is designed for you.

What You’ll Be Working On

Building/evolving AI-powered applications using modern frameworks and open-source tools
Designing and shipping production-grade software with real users, not hobby projects
Developing backend systems in Rust and application layers in Django
Working with large language models and AI tooling, including OpenAI-based systems
Contributing to new product development as well as modernizing existing platforms
Collaborating closely with leadership and other senior engineers to shape technical direction
Operating as a true individual contributor with autonomy and accountability

What We’re Looking For

8 to 12 years of professional software engineering experience
Minimum of 5 years working on enterprise or production-grade software
Hands-on experience working with LLMs, AI tooling, or OpenAI-style frameworks
Demonstrated ability to ship software used by hundreds or thousands of users
Ability to self-start, propose solutions, and execute with empowerment
Comfortable owning problems end-to-end, from concept to deployment
Experience in national security or defense is not required, but interest in the space is expected.

How We Evaluate Candidates

We take the candidate experience seriously while maintaining a high bar.

Our interview process includes
Brief cultural and behavioral interview
Deeper dive into your technical skills through a customized case study evaluation
Closing out with a brief core values presentation to assess intentionality, alignment, and communication fits within the team

We value thoughtful preparation, clarity of thinking, and ownership more than perfect answers.

Compensation and Equity

Base salary range: $150,000 to $220,000
Exceptional candidates may be considered at higher compensation levels
Bonuses and performance-based incentives
Opportunity to grow with the company toward a targeted IPO timeline

We are transparent about compensation and structure offers thoughtfully for the right people.

REQUIRED Experience:

Strong software development and coding experience with modern programming frameworks and technologies.
Experience with AI-powered development, modernization, automation, or transformation tools.
Proficiency in one or more modern development stacks such as Node.js, React, Angular, or similar technologies.
Experience with Rust or Django is a plus but not required.
Demonstrated ability to build, maintain, and modernize applications using current software engineering best practices.
Strong problem-solving skills and the ability to work effectively in a fast-paced, technology-driven environment.

REQUIRED Applicant's Location:

Remote but for Maryland, Virginia or East Coast candidates ONLY
Based on Security Clearance Requirements - Candidates
Must Be United States Citizens w/ ability to Clear Security Clearance Protocols (US Residency is Required)

Why Join Us

You’ll work on real products with real impact
You’ll join a small, senior team with high standards and low bureaucracy
You’ll have visibility, ownership, and influence from day one
You’ll help shape systems, not just tickets
You’ll be part of a company focused on building real value, not inflated narratives

This is a role for engineers who want to build, not hide.

Join us in driving innovation through technology as we enhance our service delivery capabilities!
