# Szymon S. > software engineer building real-world systems across embedded software, applied ML, and full-stack | EVs & autonomy Location: New York City Metropolitan Area, United States Profile: https://flows.cv/szymon I’m a software engineer who builds end-to-end systems where software, data, and real-world constraints meet. My work spans embedded and autonomous platforms through applied ML and full-stack products, including shipping user-facing systems, designing ML pipelines, and operating services under tight reliability and resource constraints. Interested in early-stage or product-driven teams building ambitious systems. ## Work Experience ### Software Engineer II @ General Motors Jan 2025 – Present Own production embedded software and safety-critical data pipelines for EV battery thermal runaway mitigation, spanning algorithm design, testing, deployment, and release quality across vehicle platforms. ### Software Engineer @ General Motors Jan 2023 – Jan 2025 Prevented ~$480M in potential Chevrolet Bolt recall costs by redesigning and productionizing EV battery safety algorithms that detect and mitigate thermal runaway events before failure. ### Program Manager - Ultra Cruise (Autonomous Vehicles) @ General Motors Jan 2021 – Jan 2023 | Warren, Michigan, United States Technical program lead for GM’s Ultra Cruise autonomous platform, working directly with the Chief Engineer to manage launch-critical risks across perception, localization, and vehicle integration teams. ### Rotational Program - Project / CAD / Software Engineering @ General Motors Jan 2019 – Jan 2021 | Milford, Michigan, United States Rotated across battery hardware, thermal modeling, and embedded software roles, contributing to EV battery pack design, 1D thermal simulations, and production control logic. ### Full Stack Developer @ Data4Good @ University of Michigan Jan 2023 – Jan 2024 Built and deployed a full-stack web application using applied NLP to summarize humanitarian reports for a nonprofit, owning model integration, backend APIs, and production reliability under resource constraints. Redesigned API workflows to operate within strict memory limits, improving request success rates from 53% to 92% and adding monitoring to proactively detect failures. ### Engineering Lead (Mechanical & Thermal Systems) @ UW EcoCAR - DOE Advanced Vehicle Technology Competition Jan 2017 – Jan 2019 | Seattle, Washington, United States Contributed to EV and hybrid vehicle development across mechanical design and thermal systems, progressing from component-level engineering to leading thermal simulation, CAD routing, and battery airflow redesigns for competition vehicles. ### Research Assistant @ Boeing Jan 2018 – Jan 2018 | Seattle, Washington, United States Conducted experimental vibration and frequency-response analysis on riveting tools to reduce long-term injury risk for aircraft mechanics, evaluating damping designs and fail-safe mechanisms through automated and manual testing. ### Engineering Student - Automotive Summer Program @ Nagoya University Jan 2017 – Jan 2017 | Nagoya, Aichi, Japan Completed an intensive automotive engineering program in Japan, including factory visits and technical seminars at major OEMs, and delivered a capstone presentation on vehicle crash safety. ### Robotics Lead @ Advanced Robotics UW (ARUW) Jan 2017 – Jan 2017 | Seattle, Washington, United States Led mechanical design and testing for competition robots, including building an autonomous resupply system and a full-scale testing field for RoboMaster international competitions. ### Valet @ Luxe Jan 2015 – Jan 2016 | Seattle, Washington, United States Where it all started. ## Education ### Master's degree in Applied Data Science University of Michigan Jan 2022 – Jan 2025 ### Bachelor of Science - BS in Mechanical Engineering University of Washington Jan 2015 – Jan 2019 ### High School/Secondary Diplomas and Certificates Eastside Preparatory School Jan 2011 – Jan 2015 ## Contact & Social - LinkedIn: https://linkedin.com/in/szymonsarnowicz - Website: https://szymon.wiki - GitHub: https://github.com/zymoncone --- Source: https://flows.cv/szymon JSON Resume: https://flows.cv/szymon/resume.json Last updated: 2026-03-23
