# Yurii Chubenko > Engineer and researcher focused on semiconductor R&D — device characterization, reliability, and measurement. Information & Computer Engineering student at TU Graz (Graz, Austria), graduating August 2026. German C1, English C1; eligible to work in Austria without restrictions. Open to internships, working-student, and graduate roles in the semiconductor industry. Yurii Chubenko is an engineer from Kyiv, Ukraine, now based in Graz, Austria. His work centres on the physics and measurement of nanoscale semiconductor devices — characterizing single-transistor defects, reliability mechanisms, and radiation effects, backed by the instrumentation and software to capture them. He combines hands-on lab engineering (low-noise measurement, instrument automation, PCB design, firmware) with a founder's end-to-end product instinct. The authoritative source for everything here is his site, https://yurii.ch. ## Focus & positioning - Target field: **semiconductor R&D** — device characterization, reliability (TID, RTN/TDDS), low-noise measurement, lab instrumentation and automation. - Current research is exactly this: his bachelor thesis and publications study how single nanoscale transistors behave under ionizing radiation, in situ. - Open to anywhere in Austria; available up to full-time from ~autumn 2026. ## Motivation (why semiconductors) Yurii committed to nanoscale computing after the AIT Technology Talks 2024, motivated by Europe's semiconductor talent shortage and dependence on foreign fabrication, and by a conviction that the ability to produce computational power should not be concentrated in a few hands. He sought out a research group working on radiation effects in CMOS to contribute to that field directly. ## Research & publications First author on both, with co-authors Semih Ramazanoglu and Alicja Michałowska-Forsyth (Institute of Electronics, TU Graz). The thesis is part of the FWF-funded SIRENS project (Studies of Ionizing Radiation Effects in NanoScale CMOS). - [Total Ionizing Dose Influence on Trapping Activities in Nanoscale CMOS — RADECS 2026 (paper, accepted, Prague)](https://yurii.ch/l/radecs): Continuous, in-situ monitoring of a single 40 nm NMOS transistor during X-ray irradiation — resolving discrete charge trapping/detrapping and a rise in low-frequency noise that the usual before-and-after measurements miss. Headline result: step-like drain-current changes up to ~25% during irradiation, previously unreported; relevant to CERN's High-Luminosity LHC, space, and medical imaging electronics. - [Web-based Interactive Tool for Real-Time Analysis of Multi-day Nanoscale CMOS Defect Spectroscopy — MESS 2026 (poster, Vienna)](https://yurii.ch/l/mess): A single browser viewer that spans a five-day, terabyte-scale measurement campaign and zooms down to one ~25 nA charge-trapping step, with no pre-filtering and no memory limit. - [Bachelor thesis — RTN / TDDS measurement setup](https://yurii.ch/projects/thesis): The custom acquisition system behind the above — a ping-pong oscilloscope configuration captures charge-trapping events; instrument control over VISA / HiSLIP / LXI, orchestrated by nine Python microservices, with React/Vite and Dash/Flask dashboards. ## Experience - **Student Project Assistant — Institute of Electronics, TU Graz (2026):** cryogenic setups (~9 K), DC measurements, chip bonding, X-ray irradiation experiments, and instrument automation. - **Founder — Overda (2019–2022):** founded and ran a hardware startup building microclimate sensors for industrial and commercial use — hardware, firmware, cloud, and business. Took products to market and scaled the team to about seven people; the company wound down after Russia's full-scale invasion of Ukraine. (Public GitHub org: Overda; device firmware in the ESP_OVERDA_UPD repo.) - **Independent engineering consulting (2020–2025):** electrical and production engineering, education, and mentoring. ## Leadership & teams - **Aerospace Team Graz (2023–present)** — Flight Computer / Business Module; Deputy Secretary. Built the team's first cargo drone end-to-end (electronics, firmware, flight operations, repairs, modifications, assembly); it flew successfully in 2025 with a 10 kg max payload and ~3 kW max power. Also contributed PCBs (a black-box reader board; a mission-control interconnect board) and testing to the EuRoC 2025 rocketry effort, on a team that placed first in Europe. Supports business and PR for the ~100-member team (newsletter, assets). - **BEST Graz (2022–present)** — successive roles as Secretary (2023–24), President (2024–25), and Treasurer (2025–26) in this Board of European Students of Technology chapter (~25 active members); organized career events, cultural exchanges, and short academic courses. ## Skills - Semiconductor & measurement: device physics, defect characterization, reliability mechanisms (TID, RTN/TDDS), low-noise current measurement, instrument control (VISA / LXI / HiSLIP), oscilloscopes (R&S RTO), SMUs (Keysight B2962A), X-ray irradiation, cryogenics, chip bonding. - Hardware & embedded: PCB design (KiCad, Altium), VHDL & Verilog (from personal FPGA projects), STM32 & ESP32 microcontrollers, RTOS (basic), soldering — a self-described lab all-rounder. - Software & data: Python scientific/data stack, React/Vite, Next.js, automation/DevOps, Fusion 360 and 3D printing. ## Education - B.Sc. Information & Computer Engineering, TU Graz (2024–2026; in 6th semester, writing the thesis). - Technical Lyceum of the National Technical University of Ukraine "Kyiv Polytechnic Institute", Kyiv (graduated 2021; 11.2/12 GPA, honors in physics and informatics). ## Awards & scholarships - European Forum Alpbach Scholarship Holder — Industriellenvereinigung (2025). - Recognition for contribution to the Austrian school system — Federal Ministry of Education, Science and Research (2024). - IV-MINT Scholarship for High-Potentials from Ukraine — Industriellenvereinigung (2023). ## Languages German (C1, certified — works and studies in German), English (C1, certified), Ukrainian (native). ## Contact - Email: mail@yurii.ch - LinkedIn: https://at.linkedin.com/in/yurii-chubenko - GitHub: https://github.com/YuriiChubenko - CV (PDF): https://yurii.ch/YuriiChubenkoCV.pdf - Based in Graz, Austria; open to internships, working-student and graduate roles across Austria.
