# Alexander Plewinski > Mechanical Engineer at Seneca Location: San Francisco Bay Area, United States Profile: https://flows.cv/alexanderplewinski Building systems to protect our environment. ## Work Experience ### Mechanical Engineer @ Seneca Jan 2025 – Present | San Francisco Bay Area Leading avionics and perception hardware development for semi-autonomous fire-suppression drones. ### Hardware Design Engineer @ Forward Jan 2024 – Jan 2024 | San Francisco, California, United States • Worked closely with a team of product managers, industrial designers, embedded systems SWEs, and vendors designing Carepods, a scalable, self-serve primary care kiosk • Owned engineering of seven subsystems consisting of 200+ parts and 25% of full system BoM. Reduced per-subsystem cost by up to 70% and assembly time by up to 95%. • Responsibilities included: product definition and aligning stakeholders on engineering requirements; engineering design including CAD, tolerance stackup analysis, DFMA, and prototyping; vendor management; and quality control test planning & execution • Lead design engineer for the reimagined Body Scanner, which generates a 3D body model and body measurements of a static human subject using cameras integrated within the Carepod interior. This included optimizing camera configurations for SW, HW, and aesthetic requirements; DFMA engineering of camera mounts, transmissible A-surfaces, and inter-subsystem APIs; and quality control throughout manufacturing and assembly. ### Undergraduate Researcher @ University of California, Berkeley Jan 2023 – Jan 2024 | Berkeley, California, United States Worked with professor Grace Gu on projects focused on 4D printing and self-assembling robots. ### Mechanical Engineering Intern @ SpaceX Jan 2023 – Jan 2023 | Hawthorne, California, United States • Executed detailed test campaign to make system-wide recommendations for torque specification and seals for fittings operating at extreme pressures and temperatures. • Designed test plan and tooling for design validation of novel valve pack with 8 independent valves. • Compiled resources and best practices for bolted joints and K-factor determination to increase joint reliability. ### Suspension Engineer @ Berkeley Formula Racing Jan 2021 – Jan 2023 | Berkeley, California, United States • Redesigned front suspension to address compliance issues under off-axis loads in the direct actuation pushrod • Conducted failure analysis on yielded and cracked upright using electron microscopy and fractography to determine nature and load case of failure • Designed and manufactured precision welding jigs for chassis tabs which determine the location of our suspension control arms and define the vehicle's dynamics • Supported optimization of rear upright for stiffness and weight reduction by simulating multiple individual and compound load cases in Ansys which the part would experience during racing ### Product Design Intern @ Apple Jan 2022 – Jan 2022 | Cupertino, California, United States • Served as Directly Responsible Individual (DRI) for key module on an iPad program in early development • Implemented a design new to the iPad PD team to add new functionality and increase product reliability • Conducted three studies to evaluate performance of new design in terms of reliability and user experience ### R&D Intern @ Johnson & Johnson Jan 2021 – Jan 2021 | Houston, Texas • Created prototype for implantable, bioabsorbable sensing device for remote monitoring of colorectal surgery sites • Designed anatomically representative testbed for evaluating the efficacy of different mechanical thrombectomy devices for treating ischemic strokes • Led trials on porcine lung tissue to collect data on postoperative persistent air leaks and conducted preliminary analysis of leak characteristics ### 3D Printing Technician @ Sawgrass Orthodontics Jan 2020 – Jan 2020 | Plantation, Florida, United States ### Product Design Contractor @ Bioverse Labs Jan 2020 – Jan 2020 | Miami, Florida, United States ### Shadow @ Motorola Solutions Jan 2018 – Jan 2018 | Plantation, Florida Shadowing business and engineering employees at Motorola Solutions to learn about engineering and business applications in a large corporation ### Cashier @ InUnison Apparel Jan 2017 – Jan 2017 | Plantation, FL ## Education ### Bachelor's degree in Mechanical Engineering University of California, Berkeley ### American Heritage High School ## Contact & Social - LinkedIn: https://linkedin.com/in/alexander-plewinski-666731167 --- Source: https://flows.cv/alexanderplewinski JSON Resume: https://flows.cv/alexanderplewinski/resume.json Last updated: 2026-04-13
