- Embed with customers and mission owners. Dive deep into customer workflows to collect feedback, debug in the field, and iterate quickly.
- Collaborate across disciplines. Building effective AI-native applications crosses many disciplines. To build the right application you will work with AI Engineers to understand the capabilities an limitations of AI agents, designers to pick the right UX patterns for users, and product owners to solve real-world customer workflows.
- A track record of shipping high impact, fullstack, and preferably data or AI-enabled applications
- Deep and current knowledge of AI capabilities, LLM tooling, and emerging trends.
- An excitement to work cross-functionally with other engineers, designers, and machine learning engineers

- Active or previous TS / SCI Clearance is a plus but not needed
