Tesla has lost another key figure from its AI hardware team, with Shishuang Sun, former Senior Director of AI Hardware Design, joining DensityAI. This move highlights ongoing talent shifts in the competitive field of AI chip development, especially as DensityAI continues to attract former Tesla engineers.
Another Senior Departure from Tesla’s AI Hardware Team
Shishuang Sun, who spent over five years at Tesla working on Dojo and Autopilot computers, has joined DensityAI as of July. Sun’s new role is listed as ‘Packaging and System Hardware,’ a critical specialty in the chip industry.
Sun’s departure is notable given his seniority—he left Tesla as Senior Director of AI Hardware Design, a role central to transforming Tesla’s custom silicon into operational systems. His expertise includes IC packaging, power modules, PCB design, and system thermal engineering.
Career Path: From Tesla to DensityAI
Sun first joined Tesla’s Autopilot hardware group during the Jim Keller era, contributing to the company’s initial Full Self-Driving computer. After a stint at Waymo as a hardware engineering manager, he returned to Tesla in January 2021 as a principal engineer on AI hardware for both Dojo and Autopilot.
He was promoted to Senior Director of AI Hardware Design in April 2025, overseeing the integration of chip designs into real-world automotive systems.
DensityAI: A Startup Built from Tesla’s Dojo Team
DensityAI was founded by Ganesh Venkataramanan, the former chief of Tesla’s Dojo project, after Tesla shut down Dojo in August 2025. The startup has attracted around 20 engineers from Tesla’s supercomputer team, including CTO Bill Chang, another Tesla veteran.
DensityAI focuses on developing chips, hardware, and software for AI data centers targeting automotive, robotics, and industrial sectors—areas Tesla had previously pursued with Dojo.
Tesla’s Ongoing Chip Ambitions and Challenges
Tesla continues to invest heavily in custom silicon, having taped out its AI5 chip in April. However, volume production is not expected until mid-2027. The next-generation AI6 chip is planned for Samsung’s 2nm process, and Tesla, alongside SpaceX, is proposing a $20 billion-plus ‘Terafab’ chip factory in Austin.
These projects rely on specialized talent in chip packaging and system integration—the very expertise Sun provided.
Competitor Comparison
Tesla’s main competitors in the AI hardware and autonomous driving space include Nvidia, which supplies chips to many automakers, and Waymo, where Sun previously worked. DensityAI, now staffed with former Tesla engineers, is emerging as a direct competitor in the AI data center and automotive chip sector.
Historical Context
Tesla’s global vehicle sales reached 1,789,226 units in 2024, a dramatic increase from just 22,477 units in 2013. However, Model Y sales saw a -3.1% year-over-year decline, reflecting both the company’s rapid growth and recent market pressures.
The ongoing loss of senior engineering talent comes at a time when Tesla is pushing to maintain its technological edge amid increasing competition.
Why this matters
The migration of top engineering talent from Tesla to DensityAI underscores the importance of people in the custom silicon business. As Tesla bets its future on in-house AI chips for vehicles and robotics, retaining experts in packaging and system integration is critical.
Losing key staff to a startup built from its own former Dojo team could impact Tesla’s ability to deliver on ambitious chip projects and maintain its leadership in AI hardware.
What this means for buyers
For consumers, these shifts in Tesla’s engineering team may not have immediate effects, but they highlight the challenges automakers face in developing advanced AI and autonomous driving systems. Buyers should watch for updates on Tesla’s chip development timelines and any potential impacts on vehicle features or delivery schedules.
Those considering Tesla vehicles can also compare the company’s AI and autonomous driving capabilities with competitors, as the landscape continues to evolve rapidly.
