Legion is building secure, reliable AI systems trusted by government and enterprise leaders. Born from a Department of Defense partnership and collaborating with world-class partners like Palantir, Nvidia, HPE, and Oracle, Legion embeds intelligence inside complex systems to unlock data, accelerate human workflows, and strengthen mission-critical operations.
We're seeking an Agentic AI Engineer to bridge the gap between our AI platform and customer outcomes. You'll take platform capabilities—agents, workflows, memory, reasoning, integrations, and tools—and transform them into polished, customer-ready applications that deliver immediate operational value. This is an end-to-end engineering role where you'll work directly with product and platform engineers to rapidly build, iterate, and ship AI applications.
Key Responsibilities:
- Build agentic applications solving real customer use cases using platform capabilities
- Design agentic workflows, plugins, and tool integrations that deliver measurable customer value
- Translate ambiguous problems into intuitive AI experiences
- Rapidly prototype, gather feedback, and iterate solutions into production-ready form
- Partner with platform engineers to inform abstractions and reusable components
- Identify patterns across customer deployments and evolve them into reusable products
- Own customer-facing quality across UX, reliability, performance, and evaluation
Requirements:
- Bachelor's or Master's degree in Computer Science, Artificial Intelligence, Engineering, or related discipline
- 3–5 years of software engineering experience
- Production experience building agentic AI applications using AI agents, workflows, MCP, and tool orchestration
- Ability to move quickly from idea to working product while maintaining high engineering quality
- Strong product instincts—care about usefulness, not just technical impressiveness
- Experience integrating APIs, enterprise systems, and external data sources
- Excellent communication and collaboration across engineering and product teams
- Growth mindset and low ego; eager to learn new tools, technologies, and adapt when needed
- Drive to foster collaboration, psychological safety, and technical excellence
- Strong advocate for inclusion in technical discussions at all levels
Preferred Qualifications:
- Start-up experience or comfort in 0→1 product environments
- Solid understanding of AI security practices (RBAC/ABAC, audit logging, prompt-level safeguards)
- Exposure to regulated or sensitive industry environments (finance, healthcare, telecoms)
Note: US Citizenship or Greencard required due to US Government contract requirements. Must be domiciled in the US with permanent residence. Identity verification through CLEAR ID required as part of application process.
