About The Job

At Jaxon, we’re focused on making AI trustworthy for mission-critical environments. Our core technology is built to enable the safe deployment of AI in high-stakes settings, particularly across the Department of Defense. While our company supports both commercial and government applications, this role is dedicated to the defense side. As a Machine Learning Engineer at Jaxon, you’ll be embedded on a sensitive project designed to help solidify the U.S. Space Force’s ability to use AI reliably. The work centers on advancing machine learning capabilities to meet the rigor and reliability required for national security operations. Existing SECRET security clearance strongly preferred; eligibility to obtain clearance is required if not already held.

Jaxon’s product, Domain-Specific AI Language (DSAIL), forms the basis of most of our deployments. This role will focus on increasing security and reliability for our customers through implementing and building on DSAIL’s capabilities. A particular emphasis is placed on addressing the fundamental limitations of LLMs – specifically around context and logical reasoning.

The Basics Of This Role Requires The Ability To

• Collaborate Across Teams : Work with cross-functional, geographically distributed teams to integrate ML models into our existing systems and workflows, enhancing product capabilities.
• Optimize Data Processing and Model Performance : Conduct comprehensive data management including preprocessing, feature engineering, and model evaluation to improve accuracy and efficiency.
• Technical Proficiency with an NLP focus : Demonstrate solid machine learning engineering experience, particularly with NLP applications and unstructured data in a cloud environment. Fluency in Python is essential.
• Understand Large Language Models : Operationalize intimate familiarity with the model deployment process, optimization of LLM parameters for specific behaviors, and a general understanding of LLM functionality and use cases. Previous experience with AI / LLM governance and guardrail development is a big plus.

Nice-To-Haves

About Jaxon is on a mission to make AI trustworthy. Developed through R&D with the U.S. Department of Defense, Jaxon converts complex rule sets—whether from policy manuals, onboarding playbooks, compliance protocols, or SME conversations—into executable logic. It extracts the key ‘questions’ hidden in unstructured docs, builds rule-driven evaluators, and tracks what’s being asked and why. The result : consistent, auditable, and provable reasoning—bringing structure, oversight, and trust to LLM-driven workflows.

What Makes Jaxon Different?

Added Perks

About You You're the type of person who's naturally driven—not necessarily because you built a rocket in your backyard as a kid, but because you have a genuine curiosity about the world of technology. In your spare time, you might find yourself deep-diving into technology subreddits, following the latest industry trends, or exploring which companies are innovating and how. Your passion isn't just about staying informed; it's about thinking how you can take these emerging concepts and scale them up, make them faster, or more impactful. At Jaxon, we're looking for someone who sees a baseline and instinctively wants to build beyond it. If you’re ready to take what exists and make it extraordinary, you’ll fit right in.

We are looking for somebody who thrives in an environment where day-to-day priorities and tasks may rapidly change. The role is not a fit if you value "business as usual".

We value team members who are bold enough to pitch creative ideas, even if they're still rough around the edges or might not make the final cut.

Education And Length Of Experience

Applicants should have a bachelor's degree in Computer Science or similar. An MS or PhD in Computer Science, Statistics, Physics, Mathematics or any related Engineering field preferred. Candidates should have a minimum 5 years of experience in similar roles.

Jaxon is proud to be an equal opportunity workplace and is an affirmative action employer. We are committed to equal employment opportunities regardless of race, color, ancestry, religion, sex, sexual orientation, age, marital status, disability, or Veteran status.
