Staff Software Engineer, Data Intelligence

Required

• 5+ years building and operating production backend or data-intensive systems
• Production experience with LLM systems, including multi-step, tool-using, or agentic workflows
• Experience measuring and improving model quality, through evals, prompting, fine-tuning, or a mix
• Experience designing distributed systems, asynchronous workflows, and reliable data-processing services
• Working knowledge of data warehousing, ideally applied to versioned datasets, lineage, or feedback capture
• Experience running containerized applications on a major cloud platform ([AWS/GCP/Azure])
• 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 you 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.
• We move fast, work smart, and hold ourselves to a high bar. Axion is 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.
• Collaborate deeply. Feedback is part of how we build — everyone has a voice, and ideas win on merit.
