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., * 401(k) matching

About Jaxon: 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?

• Human First: Our leaders get it - life happens. Whether it’s flexible working hours or understanding the need for a mental health day, we prioritize your well-being. Our CEO recognizes that happy people do the best work and he backs that up with an empathetically led culture - and I’m not just saying that because he’s going to read this post.

• Laid-Back Culture: We know that the best work comes from a place of comfort and authenticity. At Jaxon, you’re encouraged to be yourself, dress casually, and embrace your quirky side. It’s just one of the benefits of being an early-stage, high-growth startup.

• Tech Lover’s Dream: From hackathons to tech talks with industry leaders, we fuel our passion for innovation with constant learning and development opportunities.

• Grunt Work to Grand Projects: Every task you tackle, big or small, matters. You think I’m writing job descriptions for fun? Sometimes things need to get done and it’s an all hands on deck situation to get them to the finish line. We’re looking for team players who understand that achieving groundbreaking AI innovations sometimes involves rolling up your sleeves to tackle the essential, yet less glamorous tasks.
