Job description

Key responsibilities in your new role

• Define design requirements and microarchitectures for digital IPs in upcoming Automotive Microcontroller families, with particular focus on mixed-signal IPs and DSP blocks
• Design and develop RTL and UPF, leveraging AI for design and concept exploration where applicable
• Analyze domain-specific workloads to identify performance and power bottlenecks and opportunities for improvement
• Collaborate with experienced Architects to assess feasibility, refine concepts, and develop new design ideas
• Ensure design quality through required checks and tools, including Synthesis, Lint, CDC, RDC, DFT, and STA
• Collaborate closely with designers and Verification Engineers to ensure high-quality deliverables
• Mentor and coach junior designers while working effectively within a diverse, geographically dispersed team, using strong communication, influencing, and negotiation skills

You combine deep technical expertise in digital design with strong problem-solving and analytical skills and a passion for innovative semiconductor solutions. You have a pragmatic and enthusiastic approach and enjoy collaborating in international, cross-functional teams to turn advanced DSP concepts into robust, efficient implementations.

Qualifications and skills to help you succeed

• University Degree in Electronic or Computer Engineering, with 10+ years of experience in Digital IC design, digital microarchitecture, RTL development, and associated design flows
• Strong knowledge of DSP fundamentals, including sampling theory, quantization, FFT, spectral analysis, signal conditioning, noise analysis, aliasing, and signal integrity considerations
• Hands‑on experience in digital filter design and optimization, including FIR/IIR and low-pass, high-pass, band-pass, and notch filters, using fixed‑and floating-point implementations with consideration for performance, latency, and power
• Experience with mixed‑signal systems, including ADCs, DACs, sensor interfaces, and communication signal chains, as well as translating DSP algorithms into embedded software, FPGA, or ASIC implementations
• Proficiency in MATLAB/Simulink, Python (SciPy/NumPy), or equivalent tools to model, simulate, verify, and tune DSP algorithms and signal‑processing functions
• Experience in RTL and UPF design and EDA tools for Synthesis, Lint, CDC, and STA; knowledge of Verilog and SystemVerilog is an advantage
• Fluency in English with excellent verbal and written communication skills
