Forward Deployed Engineer (TS/SCI Clearance Required)

About Us

Legion is at the forefront of AI, building secure, dependable agentic systems that empower people tackling critical challenges. Born from a DoW partnership and trusted by leaders across government and enterprise, Legion embeds intelligence into complex systems to unlock data, accelerate workflows, and harden mission-critical operations. Our agentic platform integrates AI into existing software, optimizing, not replacing, workflows. We collaborate with industry leaders like NVIDIA, HPE, Palantir, and Oracle to build infrastructure that boosts human capability.

We are seeking bold thinkers and doers to shape a secure, grounded, and collaborative AI future.

The Role

This position requires a US Department of Defense or Intelligence TS/SCI clearance.

We are looking for a forward-deployed engineer to work directly with customers, designing and building custom workflows on our agentic AI platform. This is a hands-on role focused on rapid development of “app packs” and workflows that solve real operational problems. You will act as both a builder and a translator, turning ambiguous requirements into functional systems. You will be embedded with end-users, transforming requests into transformative agentic AI solutions that revolutionize workflows.

You will spend 80–100% of your time embedded with customers, operating autonomously in classified or constrained environments. Success requires autonomy, strong communication, and the ability to ship practical solutions quickly. You will also serve as a critical feedback loop to our product and engineering teams, surfacing patterns, feature gaps, and platform improvement opportunities.

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

Responsibilities

• Embed with customer teams to understand mission workflows, pain points, and operational constraints.
• Design and build custom applications and workflows (“app packs”) on top of the platform.
• Rapidly prototype and iterate on agentic AI solutions in real-world environments.
• Translate non-technical user needs into technical implementations.
• Operate independently in forward-deployed environments with minimal oversight.
• Gather and synthesize product feedback, feature requests, and usage insights.
• Collaborate with product engineering and agentic solution teams to influence roadmap and capabilities.
• Integrate with enterprise systems (data platforms, ticketing systems, collaboration tools, etc.).
• Build lightweight UI components and interfaces where needed to support workflows.
• Support deployment, troubleshooting, and ongoing iteration of solutions in the field.

Qualifications

• 4+ years of experience in Forward Deployed Engineering, Solution Engineering, or similar customer-facing technical roles.
• Experience building and shipping full-stack applications or prototypes in production or near-production environments.
• Proficiency in Python, JavaScript/TypeScript, or similar scripting languages.
• Experience integrating with enterprise systems (e.g., Microsoft O365, Palantir Foundry, Databricks, ServiceNow, Atlassian).
• Ability to build simple UI/UX using frameworks like Node.js, Next.js, or React.
• Proven ability to operate autonomously and solve ambiguous problems.
• Strong communication skills with both technical and non-technical stakeholders.
• Experience working in classified or restricted environments is a plus.
• Due to Government contract requirements, we are only able to hire US citizens or Green Card holders.
• This position requires a US Department of War or Intelligence TS/SCI clearance.

Domain Experience

• 4+ years supporting military, intelligence, or defense-related environments.
• Familiarity with mission domains such as operations, logistics, intelligence, or C4/IT systems.
• Experience working with government or federal customers preferred.

Preferred Qualifications

• Experience building or deploying AI/ML systems, especially agentic workflows.
• Familiarity with tools such as n8n, Palantir Foundry, or other workflow/automation platforms.
• Experience evaluating AI system performance and interpreting results.
• Exposure to product telemetry, usage analytics, or feedback-driven iteration.
• Experience working in early-stage or high-growth startup environments.

Why Join Us

This role is at the intersection of product development and real-world application. You will build systems that are immediately deployed and tested in the field, directly impacting customer success. If you want to work close to the mission, own outcomes end-to-end, and shape both product and customer success, this is the role for you.
