What are Physics Programmers?

Physics Programmers are specialized software developers who design and implement the systems that simulate real-world physics in video games and other interactive applications. They work on creating realistic movement, collision detection, fluid dynamics, and other physical interactions within a digital environment. Their work ensures that objects in a game or simulation behave in ways that are believable and consistent with the laws of physics. Physics Programmers often collaborate closely with game designers, animators, and other programmers to create immersive and responsive experiences.

What are the key skills and qualifications needed to thrive as a Physics Programmer, and why are they important?

To thrive as a Physics Programmer, you need a strong background in computer science, mathematics (especially linear algebra and physics), and proficiency in programming languages such as C++ or Python. Familiarity with physics engines (like Havok or PhysX), game development platforms (such as Unreal Engine or Unity), and optimization tools is typically required. Strong problem-solving skills, creativity, and effective communication help distinguish top performers in this field. These skills ensure the creation of realistic, efficient, and engaging physical simulations that enhance the overall user experience in interactive applications.

What are the typical challenges a Physics Programmer faces when integrating physics systems into a game engine?

Physics Programmers often encounter challenges when ensuring that physics systems interact seamlessly with other game engine components, such as animation, rendering, and AI. Balancing performance and accuracy is key, as realistic physics can be computationally expensive and impact frame rates. Debugging complex interactions and edge cases—like collision detection or character ragdoll behavior—requires strong problem-solving skills and close collaboration with designers and gameplay programmers. Effective communication within a multidisciplinary team is crucial to align physics features with the overall game vision.

Job description

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.
DEVICE PHYSICS ENGINEER, SOLAR CELLS (STARLINK)
Starlink believes in providing fast, reliable internet to those that need it most. We design, build, and launch the world's largest and most advanced satellite constellation that is capable of delivering high-speed internet to even the most remote locations.
We are seeking an exceptional Device Physics Engineer to lead end-to-end cell efficiency ownership in our high-volume silicon heterojunction (SHJ) solar cell fab. Acting as the central process integration expert, you will collaborate with specialized process and equipment engineers to maximize cell performance to achieve state of the art efficiency, define wafer specifications, design space-optimized cell architectures, and establish comprehensive metrology and reliability frameworks. Your work will span from ingot growth all the way through cell production (wafer prep, deposition, passivation, metallization) and module fabrication. Your work will ensure our solar cells deliver unmatched power density and durability for Starship, Starlink, AI Satellites, and deep-space missions.
You will spearhead state of the art production processes, and work through the entire life cycle of setting up a greenfield solar cell production plant, including equipment/lab procurement, plant design/layout, equipment commissioning and ramp-up, recipe and process development, and working to develop a world-class production team and environment. Your work will form the backbone of the Starlink network (photons of sunlight in is directly proportional to photons of data out to customers!) and help provide internet to tens of millions of customers all around the world.
RESPONSIBILITIES:
  • Own end-to-end cell efficiency roadmap: integrate processes across ingot growth, wafer prep, deposition (PECVD, PVD), passivation, metallization, and testing to drive significant efficiency gains
  • Define and qualify incoming wafer specifications (e.g., resistivity, lifetime, thickness uniformity) for SHJ compatibility, partnering with suppliers and internal supply for tens of GW-scale volumes
  • Design and iterate SHJ cell architectures optimized for space: Radiation tolerance (proton/electron fluence), thermal vacuum cycling, UV exposure, and high specific power (>250 W/kg)
  • Develop fab-wide metrology strategy: Select, commission, and calibrate inline/offline tools (e.g., lifetime testers, IQE/EL mappers, TRPL, LBIC, SEM, Ellipsometry, Raman, etc.) for real-time process control and yield correlation
  • Lead reliability engineering: Establish accelerated life testing labs (HALST, damp heat, mechanical stress, radiation, TVAC, UV, etc.), define qualification protocols per ECSS/AEC-Q standards, and predict 25+ year mission lifetimes
  • Build and maintain physics-based models (e.g., PC1D, Quokka, Sentaurus) for loss analysis (recombination, shading, passivation) and guide DoE with process teams
  • Analyze production data to identify efficiency limiters, spearhead cross-functional improvements, and support fab ramps
  • Mentor team on PV physics fundamentals and represent solar cell performance in design reviews for spacecraft power systems
  • Develop, implement, and maintain new and/or improved manufacturing processes, equipment, technologies, and facilities
  • Analyze production processes and machinery from a first principles, physics-based approach
  • Develop experiments to diagnose and correct manufacturing problems, utilizing robust DOE and statistical methodologies
  • Optimize process conditions and materials to improve the optical and electrical quality of solar cells
  • Develop project plans, budgets, and cost/benefit analysis for implementation of new processes or machines
  • Prepare detailed content for technical design reviews
  • Demonstrate extreme ownership of the production outcome of the Starlink solar factory across yield, uptime, and cost
  • Scale lab/pilot level processes to production environments, working closely with the process engineering team
