How I work

I have a strong bias for hands-on engineering where the data proves the design. The Starship program taught me that humility is part of the engineering: look past your own assumptions, lean on the technicians who run the hardware every day, and care about getting it right for the vehicle, not just your own design. Everything I build runs through the same four steps: design, build, test, and scale.

SpaceX

Starship Thermal Hardware Engineering InternCape Canaveral, FL
DesignBuildTestScale

I worked on the team responsible for Starship's thermal protection hardware at the Cape. Day to day was a balance between development work, meaning research, design, planning, and building out project proposals, and the production floor, where I worked with technicians to integrate equipment or run down root causes when something failed. Much of it was taking requirements that were undefined or still moving and turning them into proposals, engineering models, drawings, and hardware, then validating how they actually held up during integration and testing.

Two areas took most of my time. The first was inspection and test: developing clearer verification methods for heatshield components, from the first step through integration on the vehicle, including physical testing on T1 flight hardware. The second was equipment engineering: running trade studies, specifying cells, and staying with them through procurement, installation, and the first weeks on the floor. My largest project was an automated bonding cell for Starship V3, designed from the start around the rate the program needs. In July, when the thermal protection system, still the most critical system on the vehicle, had flight-blocking needs in Texas, I surged from the Cape to the Starfactory at Starbase to help on site.

I split my time close to evenly between the desk and the floor. I mentored technicians and other interns on the work I owned, and learned that a big part of being an efficient engineer is teaching others how they can help instead of doing everything yourself. Late in my term I presented my work to Starship program leadership, and my review package became a reference for the rest of the team.

Operating at the speed of a flight program was my biggest learning curve. Early on, work I had put real effort into was set aside as requirements shifted, which taught me not to take pivots personally and to refocus where the team needed me. Later I was trusted with sole ownership of several systems that are still operational today, and I learned that acting quickly and with intent, then learning from the result, beats waiting for the perfect decision.

Firehawk Aerospace

Propulsion Design Engineering InternAddison, TX
DesignBuildTestScale

I was a propulsion design engineering intern at a hybrid rocket startup in Addison, Texas. Day to day was a balance between design work in Creo Parametric 9, structural analysis, and tooling development, and hands-on work on the floor.

My main project was FDM tooling for fuel grain production: one-time-use molds with O-ring glands and vacuum-capable iterations. Testing validated seal integrity, bond-layer uniformity, and cure, for a projected 360% gain in production capacity. I also spent real time in the lab formulating adhesives and iterating fuel grain geometry, which fed straight back into the same bottleneck my tooling was built to fix.

I kept up with my project well enough to go looking for more. I helped build out a water flow test stand and designed a 50,000+ lbf horizontal static fire stand, from CAD through the plumbing and assembly. On a 3,500 lbf hybrid campaign I designed, built, and ground tested parachute bay assemblies with a shear-screw breakaway and a black powder charge of my own design, and owned the test plans in Epsilon3. I also worked with the shop to CNC and lathe parts on the critical path for flight tests, including igniters and fixtures for U.S. Army programs.

What I walked away with came from the tests that didn't go the way we expected. There was a lot of failure, and a lot of moments where something I thought I understood got challenged. It taught me to work backwards from a result to find where and how something failed, and that prepared me for what came next more than any result that went right.

Space Resource Technologies

Manufacturing Engineering InternOrlando, FL
DesignBuildTestScale

I'd call this my first real engineering job. SRT made regolith simulant for aerospace customers, and the process ran almost entirely on tribal knowledge.

I spent my days watching where waste was produced, working out how to fix it, and then working entire shifts on the line myself with the operators to make sure the fix actually held. I tracked units per day, batch time, labor, faults, and downtime across hundreds of runs before changing anything.

Then I reorganized the production cells around Lean Six Sigma, integrated the equipment, and wrote the SOPs. Same-batch processing went from four weeks to six hours, and the lead manufacturing engineer adopted the flow.

UNEW

Engineering InternPort Salerno, FL
DesignBuildTestScale

My first internship, at a company that reverse engineers and manufactures replacement parts for industrial gas turbines.

Most of my time went into learning Siemens NX and redesigning several turbine fixtures and parts, then blue-light scanning the real parts on an ATOS ScanBox and comparing them to my models in GOM Inspect. That comparison is where tolerances, manufacturing defects, and what machining actually does to a design first made sense to me.

I worked through my assignments quickly enough to ask for more, so I researched hydrogen as a fuel for gas turbines, what it takes to produce, store, and use it responsibly, and presented what I found to the engineering team. It was the first time I saw how engineering actually gets done, and it's a large part of why I chose aerospace.

The story so far

Portrait of Sterling Pearson

I'm an aerospace engineering student at the University of Central Florida, finishing my degree in December 2027. In Florida, launches have always been part of the view. Chasing that feeling pulled me into a cockpit first, and then onto test stands and factory floors.

Here's the path so far, in order. Tap any entry for the photos and the story behind it.
