Who You Are

You're a builder and operator who thrives in fast‐moving, high‐accountability environments. You take pride in getting things done—thoughtfully, efficiently, and without drama. You're energized by ambiguity, skilled at bringing clarity, and comfortable flexing between strategy and execution. You value feedback—giving it, receiving it, and acting on it—and see collaboration as a competitive advantage, not a burden. You're low‐ego but high‐agency: you care about winning as a team more than being right individually. You move quickly, communicate directly, and make decisions grounded in impact and data. You don't need constant direction—you create momentum. You take ownership for outcomes, and you expect the same from those around you.

How We Operate

We move fast, work smart, and hold ourselves to a high bar. Axion isn't a 9–5—it's a place for people who take pride in their craft and are motivated by meaningful work. We respect time‐off and boundaries, but we're also realistic: hard problems sometimes require weekend pushes or late‐night thinking sessions. We support that balance—intensity with respect for recharge. We stay highly collaborative and connected throughout the day—much of our communication happens over Slack. We move quickly, share feedback often, and keep discussions open so decisions and context flow freely. If you value crisp communication, rapid iteration, and a steady hum of collaboration, you'll fit right in.

We

• Collaborate deeply. Feedback is part of how we build—everyone has a voice, and ideas win on merit.
• Leave ego at the door. Titles don’t define value; contribution does.
• Bias toward action. We iterate fast and favor progress over perfection.
• Communicate with clarity. Direct, transparent, and always in service of the mission.
• Act like owners. Everyone is accountable for outcomes, not just tasks.
• Sustain excellence. We push hard but don’t glorify burnout—we're in this for the long game.

What We Offer

• Work with cutting‐edge AI technology making a tangible impact in manufacturing
• Collaborative, mission‐driven team and supportive leadership
• Generous time off
• Competitive compensation, equity, and benefits
• Lunch stipend...and much more
