Apptronik is a human-centered robotics company developing AI-powered robots to support humanity in every facet of life. Our flagship humanoid robot, Apollo, is built to collaborate thoughtfully with people, starting with critical industries such as manufacturing and logistics, with future applications in healthcare, the home, and beyond.
We operate at the cutting edge of embodied AI, applying our expertise across the full robotics stack to solve some of society's most important problems. You will join a team dedicated to bringing Apollo to market at scale, tackling the complex challenges like safety, commercialization, and mass production to change the world for the better.
JOB SUMMARY
We are seeking an early-career Simulation Engineer to join our growing Simulation team as a generalist contributor. This is an opportunity to learn humanoid simulation across its full breadth — from physics and contact modeling through scene authoring, asset pipelines, and developer tooling — while contributing to multiple ongoing initiatives at once.
You will work across several of the team's focus areas, with near-term emphasis on supporting our dexterous-hand simulation work. As we hire a senior owner for the Dexterity domain, you will help build the foundational infrastructure they will grow into, and over time develop depth in the area where your interests and the team's needs align best.
ESSENTIAL DUTIES AND RESPONSIBILITIES:
- Dexterity Foundations: Build and maintain hand collision geometry (primitive decomposition, mesh cleanup). Author evaluation scenes and dexterity benchmarks in Isaac Lab / Isaac Sim from specifications. Run sim-to-real comparison experiments and produce comparison reports.
- Design-Time Simulation: Contribute to the CAD-to-simulation pipeline — kinematic graph extraction, collision geometry, mass and inertia property handling. Run design-space exploration experiments per protocols defined by senior team members.
- Robot Description & Asset Pipeline: Help maintain canonical robot models — joint limits, inertias, collision properties. Build and maintain regression tests and validation tooling for the robot assets the rest of the org depends on.
- Production Platform Contributions: Contribute to the simulation platform's tooling, examples, CI infrastructure, and developer documentation. Triage user-reported issues and help unblock other teams using the platform.
- Team Contributions: Own onboarding docs and example scenes that help new engineers get productive on the platform — your perspective as the newest team member is a real asset here.
SKILLS AND REQUIREMENTS:
Must-Have
- 0–2 years of professional software engineering experience (strong internship or research project experience qualifies)
- Strong Python skills
- Solid fundamentals: rigid body dynamics, linear algebra, spatial math, programming
- Coursework or project experience with robotics simulation, computational geometry, or computer graphics
- Demonstrated curiosity and willingness to work across multiple domains rather than specializing immediately
Nice-to-Have
- Hands-on experience with Isaac Sim, MuJoCo, Gazebo, or equivalent simulator (coursework or projects count)
- Familiarity with USD, URDF, MJCF, or other robot/scene description formats
- Exposure to mechanical engineering, robot hardware, or sim-to-real workflows
- Some C++ exposure
- Internship or research experience in robotics, gaming, or graphics
EDUCATION and/or EXPERIENCE:
- BS in Computer Science, Robotics, Mechanical Engineering, or related field. MS welcome but not
**PHYSICAL REQUIREMENTS **
- Prolonged periods of sitting at a desk and working on a computer
- Must be able to lift 15 pounds at times
- Vision to read printed materials and a computer screen
- Hearing and speech to communicate
