Senior simulation engineer

We are looking for a highly experienced LTspice EDA & Circuit Simulation Specialist to lead advanced electronic circuit modeling and validation activities. This role requires deep expertise in analog, digital, and mixed-signal simulation, ensuring that circuit designs meet strict performance and reliability standards before moving to hardware. The ideal candidate will act as the go-to authority on circuit simulation, providing technical leadership across engineering teams. Key Responsibilities Serve as the subject matter expert (SME) for all LTspice-related simulation work. Develop, implement, and refine complex analog, RF, power, and mixed-signal circuits in LTspice. Build custom component models, behavioral models, and subcircuits for advanced simulation. Perform in-depth analyses including transient, AC, DC sweep, Monte Carlo, thermal, and noise simulations. Lead design verification and optimization efforts , ensuring simulated performance aligns with system requirements. Benchmark and validate simulation results against real-world test data, providing design recommendations . Mentor junior engineers and establish best practices and workflows for circuit simulation. Collaborate closely with design, layout, and test engineers to ensure smooth transition from simulation → PCB → prototype . Author technical documentation , including detailed reports, simulation methodologies, and design guidelines. Required Skills & Qualifications Master’s degree or Ph D in Electrical / Electronics Engineering (or equivalent experience). Proven track record (5–10+ years) in LTspice circuit design and simulation. Deep knowledge of semiconductor device physics, power electronics, RF, and analog design . Expertise in custom model development and parameter extraction. Strong understanding of signal integrity, EMI / EMC, thermal effects, and reliability simulation . Familiarity with additional EDA platforms (PSpice, Or CAD, ADS, MATLAB / Simulink) a plus. Excellent problem-solving, documentation, and communication skills. Ability to work independently as well as provide technical leadership within a team. can be everywhere based in Spain.
