What's next...Your Company?
Spring, Summer or Fall 2025
I am seeking a hardware focused internship or co-op (6+ month preferred) for spring, summer and/or fall 2025.
I love working with small teams on fast moving projects. Solving hard problems and working from first principles are my forte.
If you have an opportunity, please reach out at Johnwrehagen at gmail dot com or on X/Twitter.
Founder of Aggie Drone Initiative - an organization with the goal of providing an opportunity for A&M engineers to get more hands on experience in designing, building and flying specialty drones.
Current project: A fixed wing vtol drone similar to the Anduril Roadrunner or ShieldAI VBat. More coming soon!
If you are interested in supporting the project, please reach out via the email above!
Led manufacturing process planning of four robotic manufacturing lines.
Developed process flows leading to elimination of $1M capex expenditure and 10% headcount reduction.
Led manufacturing planning of 19 crash service parts. Owned RFQs, evaluated proposals, presented to
management and planned implementation and production schedule through Q4 2024.
Collaborated with supplier on new tooling design. Led 50% and 100% tooling design reviews.
Coordinated root cause investigation of fastener installation failures. Investigated and identified innacuracies in
snowflake dataset, amended data filter and informed $250k capex expenditure.
Responsible for the design, manufacturing, and testing of components for a 30,000 ft-class hybrid composite rocket airframe to compete in the Intercollegiate Rocket Engineering Competition (IREC).
Spearheaded rocket bulkhead design and manufacturing, rocket-tower integration and pressure vessel integration.
Exploring Metal 3D printed bulkhead components to remove constraints of manufacturing and enable continued design evolution.
Testing and benchmarking new composite manufacturing processes for future rockets, focusing on filament wound carbon fiber tubes, future pressure vessels and characterizing anisotropic forged carbon fiber parts.
Mechanical Engineering Intern - Product Test & ManufacturingVex Robotics
June 2022 - August 2022
Designed, ran, and analyzed scientific tests to validate product functionality and define defect tolerances.
Standardized testing practices by writing technical manual and created quick start data analysis templates.
Led multiple projects from the initial ideation and pathfinding phases to multi-iteration design and full-scale production and distribution.
Used SOLIDWORKS to prototype and finalize the design of injection molded, punched, and fiber lasered parts
while working with manufacturing team to ensure design for manufacturability.
Led the solution ideation, design and manufacturing of a 150 lb robot to play the Frist Robotics Competition game in a fast paced 10 week design-build cycle.
Self-taught CAD, CAM and CNC manufacturing, led commissioning of a 4x4 CNC router and transformed team's build process from hand drawn to CAD/CAM/CNC.
Developed mini-robots as platforms to be used in summer camps and team development programs.
B.S. Industrial and Systems Engineering, focus in Manufacturing SystemsTexas A&M University
Fall 2021 - Fall 2025
I am studying Industrial Engineering with a focus in Manufacturing Systems
My goal is to combine the high level understanding of manufacturing systems from my education with the hands-on, low-level, understanding of manufacturing I have obtained in my internships, project teams and personal projects. I believe this will make me a better equipped manufacturing engineer than someone who knows only one of the two domains.
