At Walden Robotics, we envision a world where general-purpose robots dramatically improve the quality of life for all people—supporting us at home, at work, in factories, on farms, and beyond. To accomplish this, we are building a team of exceptional professionals who combine world-class technical skills with creative vision, grounded in humility and collaboration. Position Summary: We’re looking for a motivated, hands-on engineer to build simulation content pipelines that create rich, diverse, and useful environments for evaluating and improving robot policies. You’ll design production-quality systems for generating, managing, validating, and deploying scenes, assets, and scenarios at scale. As a Member of Technical Staff, you’ll own substantial parts of the simulation-content authoring stack and ensure they integrate cleanly with the broader simulation platform. Core Responsibilities: • Design and build scalable systems for authoring simulation scenes, assets, and evaluation scenarios. • Define simulation tasks and scenarios that reflect real robotics priorities and expose policy weaknesses. • Develop workflows that make simulation content composable, editable, reproducible, and easy to deploy. • Build generation and curation pipelines that combine procedural methods, asset libraries, human input, and agentic workflows. • Create validation and quality-control systems for geometry, physical properties, articulation, scene composition, and task relevance. Required Qualifications: • 2+ years of relevant experience • Strong software engineering fundamentals and experience designing, building, and maintaining substantial software systems. • Experience building simulation-ready 3D assets, with strong judgment about visual and collision geometry, including trade-offs among fidelity, physical accuracy, and runtime performance. • Up-to-date knowledge of advances in simulation-ready asset and scene generation, with the ability to evaluate state-of-the-art methods and apply them pragmatically. • Ability to own ambiguous problem areas from initial design through production deployment. Preferred Qualifications: • Familiarity with agentic systems and LLM-driven developer tooling. • Experience with robotics simulation, robot learning, and automated policy evaluation. • Familiarity with simulation platforms such as Isaac Sim, MuJoCo, or Drake.
