Forward-Deployed Engineer (Customer Solutions Engineer / Applications Engineer)

Let’s be real, AI isn’t magic; Legion was built to move beyond AI hype—delivering secure, reliable systems that work alongside the people tackling the world’s most critical challenges.

Born from a Department of Defense partnership and trusted by leaders across government and enterprise, Legion embeds intelligence inside complex systems, unlocking data, accelerating human workflows, and strengthening mission-critical systems. We don’t replace workflows—we optimize them, ensuring quality, efficiency, and reliability inside the platforms our partners already use.

With world-class collaborators like Palantir, Nvidia, HPE, and Oracle, we’re building intelligent infrastructure that enhances human capability and drives impact at the edge and across a range of enterprises.

We’re looking for bold thinkers and doers to join us in shaping the future of AI that’s secure, grounded, and built to work.

80–100% embedded with customers, working independently in classified or constrained environments

Due to Government contract requirements, we are only able to hire US citizens or Green Card holders.

We’re looking for a forward-deployed engineer to work directly with customers to design and build custom workflows on top of our agentic AI platform.

This is not a traditional product or platform engineering role. You will sit with end users, understand mission needs, and rapidly develop “app packs” and workflows that solve real operational problems. You’ll operate as both a builder and a translator—turning ambiguous requirements into working systems. You’ll have a finger on the pulse of our end users, transforming requests and requirements into truly transformative agentic AI solutions that revolutionize user workflows.

You will spend the majority of your time (80–100%) embedded with customers, working independently in classified or constrained environments. Success in this role requires autonomy, strong communication, and the ability to ship practical solutions quickly.

You’ll also act as a feedback loop into product and engineering—surfacing patterns, feature gaps, and opportunities to improve the core platform.

Due to Government contract requirements, we are only able to hire US citizens or Green Card holders.
