Professional experience for Zoltan Weitzl

  • Current 3 years and 1 month, since Sep 2018

    R&D Engineer

    Siemens Zrt.

  • 1 year and 1 month, Aug 2017 - Aug 2018

    Test Manager, Model-based Test Analyst, Test Automation Engineer

    Hyundai Technologies Center Hungary

    Effective and efficient verification and validation of software is a challenge for every project, especially with model-based technologies, smart services and embedded devices involved. Reviewing, test environment design, testing, monitoring and control of the activities involved when applying manual-, automatic-, HIL-, model- and simulation-based software design and quality control process are the pillars of my current position (see the Automotive Software Tester 2.0 syllabus for more information.)

  • 2 years and 8 months, Jan 2015 - Aug 2017

    Model-based Embedded Algorithm Development, Design Quality Engineer

    Hyundai Technologies Center

    With the new range of products to be designed, I was assigned the stand-alone tasks of analyzing, specifying and implementing application-related business logic of the product and designing and implementing the automatic, model- and simulation-based quality control workflow. Additionally, supporting team- and task force leaders in administration of agile processes and managing Fieldbus communication sub suppliers and stacks integration were a minor part of my daily business.

  • 3 years, Jan 2012 - Dec 2014

    Model-based Embedded Algorithm Development Engineer

    Hyundai Technologies Center

    The control group was extended to cover all software related aspects of electric power conversion. Product concepts, algorithms, simulation environments and early-stage design artifacts were created, each of them reaching a different level of design life cycle. A technology shift from manual to automatic code generation, from centralized to distributed version control, from text-based to model-based requirements engineering was undertaken with my contribution.

  • 3 years, Jan 2010 - Dec 2012

    Product Quality and Control System Design Engineer

    Hyundai Technologies Center

    A control group was formed to efficiently tackle difficult to solve challenges, whom I was assigned responsible for. Areas of competence were the support of QC, AS and legal certifications worldwide (BV). Development tasks on their own were simulation of equipment behavior under challenging conditions (C language), control system improvement and modifications (C language), communication interface improvement (.Net, PLC, social network integration) and technical writing activities.

  • 2 years, Jan 2009 - Dec 2010

    Embedded Software Design and Product Quality Engineer

    Hyundai Technologies Center

    Organizing and taking part in the support of manufacturing, QA and AS teams (power converters, EPlan) in Korea, supporting international sales in KR, DE, MY and TH. Point of main effort as a Design Engineer (control systems, C and .Net) lay on the organization of new feature integration and existing feature improvement to efficiently fulfill customer, and legal requirements of the target markets (business logic, legal requirements, specifications creation and function implementation).

  • 11 months, Feb 2008 - Dec 2008

    Software Design Engineer

    Hyundai Technologies Center

    Design and component/technology selection of an industrial PC-based UI, communication (Modbus TCPIP/RTU/ASCII, UDP, TCP/IP) and control system (Model-based MIMO control) for PV converters in the 100kW range. Software design in .Net and IEC 61131 (PLC programming) languages. I was preparing for my PhD studies at BUTE through the implementation of a pole position detection algorithm for PMSM machines and electrical drive performance evaluation tests.
