Job Summary:

We are seeking an AI Software Engineer – Agents to build and harden the domain-specific agents that power the Agentic Computational Engineering platform. In this role, you will design, implement, and maintain AI agents that behave like focused junior engineers – thermal analysts, supply-chain scouts, G-code validators, and more.

You will sit at the intersection of prompt engineering, tool integration, and evaluation. This role is a fit for someone who already uses LLMs daily, who gets impatient when they can't automate a task, and who wants to see their agents move real hardware in the loop, not just push text around.

You will be joining the Agentic Computational Engineering (ACE) team, a specialized group within our Advanced Technology Development organization. ACE is responsible for building Voyager's Generative Engine – the AI-native platform that compresses complex hardware development cycles from years to days. We design agentic AI systems that pair deeply with physics simulation, test data, and modern manufacturing so that Design for Manufacturing (DfM), Design for Assembly (DfA), and Design for Test (DfT) are built into the very first line of code and the very first sketch of a design.

Responsibilities:

• Design, implement, and deploy production-ready AI agents using frameworks such as LangGraph or Agent Development Kits from Google, OpenAI, or Anthropic.
• Define clear agent roles, goals, and capabilities, including prompts, tool schemas, and decision-making loops (e.g., ReAct, plan-and-solve).
• Develop and maintain Model Context Protocol (MCP) servers that expose Voyager's internal systems (PLM, ERP, simulation, repositories) to agents.
• Integrate external and internal engineering tools (e.g., Ansys, Altium, SolidWorks, Python toolchains) as robust, secure agent tools.
• Build evaluation suites and benchmarks that measure agent performance on realistic tasks (e.g., exam-style physics problems, PCB routing, CAD edits).
• Collaborate closely with domain experts to encode manufacturing, test, and safety constraints directly into agent behavior.
• Use LLMs as a development accelerator for scaffolding code, writing tests, and generating documentation for agent systems.

Required Qualifications:

• 1–5 years of professional software engineering experience (exceptional new graduates and early-career engineers encouraged to apply).
• Strong proficiency in Python and experience building backend services and APIs or ability to rapidly learn (REST/gRPC).
• Hands-on experience building LLM-powered agents or tools using frameworks such as LangChain/LangGraph or similar (professional, research, or serious personal projects).
• Demonstrated habit of using LLMs and agents to accelerate development rather than writing all boilerplate by hand.
• Experience designing and documenting clean, versioned APIs and data schemas.

Preferred Qualifications:

• Bachelor's degree in Computer Science, Engineering, Physics, Mathematics, or a related field; or equivalent experience.
• Ability to read and reason about schematics, mechanical drawings, and technical documentation.
• Portfolio of personal projects involving robotics, 3D printing, electronics, or other physical-world builds.
• Experience building internal tooling for engineering, R&D, or manufacturing organizations.
• The strongest candidates will provide links to outstanding work (or descriptions when not possible to link) and evidence of experience and passion for leveraging agentic teams for rapid development.

Voyager offers a comprehensive, total compensation package, which includes competitive salary, a discretionary annual bonus plan, paid time off (PTO), a comprehensive health benefit package, retirement savings, wellness program, and various other benefits. When you join our team, you're not just an employee; you become part of a dynamic community dedicated to innovation and excellence.

To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.
