Senior C Engineer (with C++)

Scope of the role

• Maintain and develop an analog/mixed-signal simulator in a mature product.
• Approximately 80% of the codebase is C and 20% is C++.
• Approximately 80% of tasks involve maintenance within existing C code, with 20% focused on new functionality.
• Work on algorithms that simulate electrical phenomena and translate electronic circuits into the digital world, including reflections in long lines, disturbances, noise, and electrical states on a PCB.
• Use matrix methods and systems of equations for some simulation topics.
• Take ownership of a product area and collaborate internationally.
• Work in the Polish time zone, with two afternoon meetings per week with the US West Coast team, code reviews, and architecture discussions.

Must have:

• At least 5 years of commercial software development experience.
• Fluency in reading and modifying C code, navigating a large, long-lived codebase, and experience with C++.
• Ability to manually implement and interpret C data structures, including stacks, lists, and queues, without STL support.
• Memory-handling skills: allocation, freeing, and conscious selection of variable types.
• Knowledge of data structures and algorithms.
• Understanding of modeling, including mathematical modeling.
• Experience developing and/or maintaining complex software architectures and algorithms.
• Experience with Visual Studio.
• Basic knowledge of electricity and electronic circuit construction, including current, voltage, and circuit analysis.
• Willingness to develop in simulation algorithms.
