Senior C Engineer (with C++)

Scope of the role: Maintenance and development of an analog / mixed-signal simulator - work on a mature product, 80% of the code is C and around 20% is C++. 80% of the tasks are maintenance (inside the existing C code), about 20% is new functionality development Algorithms simulating electrical phenomena - working with algorithms that translate an electronic circuit into the digital world: reflections in long lines, disturbances, noise, electrical states on a PCB. Part of these topics is solved with matrix methods and systems of equations Taking over a product area and international cooperation - working hours: Polish timezone, with two afternoon meetings per week with the team in the US (West Coast), code reviews and architecture discussions, What you need to join us: Must have: Min. 5 years of commercial experience in software development, fluency in reading and modifying C code and the ability to navigate a large, long-lived codebase, along with experience with C++ Manual implementation and interpretation of data structures in C (stack, lists, queues - without STL support) and memory handling: allocation, freeing, conscious choice of variable types Knowledge of data structures and algorithms, understanding of modeling (including mathematical modeling), experience in developing and/or maintaining complex software architecture and algorithms, work in Visual Studio Basics of the physics of electricity and of how electronic circuits are built (current, voltage, circuit analysis), willingness to grow in the direction of simulation algorithms MSc or PhD in computer science, electronics or a related field English: C1+ Ability to work within the territory of Poland (citizenship, residence card, visa, etc.) Nice to have (really nice to have, not a criteria for selection): Understanding of systems of equations and methods of solving them, and familiarity with math-based algorithms (calculus and algebra) Comfort with matrix operations - transformation, inversion, addition, working on large matrices Familiarity with electrical and electronic circuit analysis Familiarity with any hardware description language: VHDL, VHDL-AMS, Verilog, Verilog-AMS Bash scripting, knowledge of Java, scripting of measurements in TCL Experience with EDA-class products and understanding of EDA objects and principles
