XStream Trucking

Mechanical Engineering Intern; Embedded Systems Engineering Intern
Burlingame, CA (8 minute walk from CalTrain station)
Innovation Area: 
Energy Efficiency
Position Type: 
TomKat Center-supported
Internship Term: 
8-12 weeks

XStream Trucking is a close-knit team working to improve the efficiency of the $700 billion trucking industry. We believe in rapid prototyping, constant interactions with our customers, and a principle of ‘go to the pain’ to resolve any issues during development. We are looking for passionate, hands-on engineers who want to design and build something great. Our first product, TruckWings, deploys out from the cab at highway speeds directing the air over the tractor­trailer junction – eliminating the drag caused by this gap. We save our customers thousands of dollars per year per truck, and we are driven by the promise that our device has the potential to reduce emissions by more than the entire current U.S. solar market. 

Mechanical Engineering Intern


  • Flexibly solve new mechanical engineering problems every day, including:
  • Definition of product specifications and engineering requirements;
  • Development and prototyping of design concepts;
  • Modeling of parts and assemblies in Solidworks;
  • Strength and reliability testing;
  • Finite element analysis of components and assemblies;
  • Assessment of manufacturers and suppliers for their price and ability;
  • Working directly with manufacturing partners to drive out cost (DFM, DFA);
  • Acting as a technical point of contact for customers and investors.

Who should apply:

We are looking to expand our engineering team with someone who shares our love of end­to­end product development and wants to make a difference.   Specific experience in aerodynamics, trucking, and prototyping are a plus, but we are primarily interested in mechanically­inclined individuals who are willing to develop engineering solutions in CAD; design a resilient product for a harsh environment; collaborate directly with manufacturers; install prototypes on semis; and get feedback from early customers. 

Preferred Skills/Majors:

Pursuing mechanical/aerospace engineering or related degree (product design etc. also considered).  Preference will be given to students who have strong prototyping/design and communication skills, including solid modeling and finite element analysis.

Embedded Systems Engineering Intern

Internship Opportunity:

As part of our Embedded Systems team you will be continuing to develop the electronics hardware that makes the TruckWings™ work so well.  We’re interested in adding new features at a rapid rate now that we have a solid footing on the core operation of the panel system.  We will be developing new software and hardware upgrades, which we know, are going to impress our customers.

Previous interns have developed PCBs from the ground up, developed improved algorithms for J1939 CAN data processing, and created reliable diagnostics subroutines allowing us to communicate reliably with our devices in the field. 


  • Basic Circuits – Voltage dividers, NPN + PNP transistors and power calculations
  • C++ Programming – Comfortable with using libraries and functions 

Preferred Skills:

  • Experience with Eagle PCB – comfortable using external libraries.
  • Low Level Programming – Bitwise operators, Memory management and SPI


  • Enthusiasm to create revolutionary new fuel saving IoT product.
  • Hands on prototyping skills to test new ideas rapidly.
