Senior Digital Design Engineer

Location: Neuchâtel, Switzerland

Our Team:

Semtech’s Wireless and LoRa system teams in Neuchâtel and Grenoble are globally recognised leaders in Low Power Wide Area Network (LPWAN) technology. Our engineers work across the full system stack — from RF and analog design through to digital architecture, protocol development, and cloud connectivity — enabling industry-leading, low-power, long-range wireless solutions.

You will be part of a highly collaborative and innovative environment, contributing to the next generation of LoRa and LoRaWAN system architecture
, shaping the future of connected devices across industrial, infrastructure, and consumer markets.

Job Summary:

The Senior Staff Digital Design Engineer is responsible for leading the design and development of digital subsystems within complex mixed-signal ICs, from initial concept through to lab validation.

This role plays a key part in defining digital architectures, implementing high-performance and low-power designs, and collaborating cross-functionally to ensure successful product development and production readiness. The position requires strong technical expertise, problem-solving capability, and the ability to contribute to innovation and continuous improvement within the design team.

Responsibilities:

• Design and implement digital subsystems, including CPU-based architectures, FSMs, interconnects, and peripherals (e.g. I2C, SPI, analog controls) (40%)
• Define and architect digital system blocks, contributing to system-level design decisions and trade-offs (10%)
• Collaborate with analog design teams to define interfaces and ensure seamless mixed-signal integration (10%)
• Debug and analyse RTL and verification issues, identifying root causes and driving resolution (10%)
• Support block-level and chip-level verification activities in collaboration with verification teams (10%)
• Contribute to lab validation, product qualification, and cross-functional engineering efforts with Validation, Test, and Product teams (10%)
• Drive continuous improvement of design methodologies, tools, and overall design quality (10%)

Minimum Qualifications:

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or related field
• 8+ years of experience in digital IC design, preferably within mixed-signal environments
• Strong knowledge of digital IC development, including frontend-to-backend flow, timing closure, and low-power design techniques
• Experience with MCU-based architectures (e.g. ARM, RISC-V, STM
  32) and digital microarchitecture
• Proficiency in System Verilog, Verilog, or VHDL, along with scripting languages such as Python, Tcl, or Perl
• Experience with industry-standard EDA tools (e.g. Synopsys, Cadence, Siemens)
• Understanding of verification methodologies (e.g. UVM/OVM, formal verification)
• Familiarity with standard hardware interfaces (e.g. I2C, I3C, SPI, MIPI)
• Strong analytical, problem-solving, and communication skills
• Ability to work independently while collaborating effectively within cross-functional teams

Desired

Qualifications:

• Experience with wireless communication systems (e.g. BLE, IEEE 802.15.4)
• Knowledge of transceiver architectures, modulation/demodulation, and signal processing
• Exposure to cryptographic block design
• Experience with FPGA design and FPGA-based system validation
• Familiarity with version control and collaborative development tools (e.g. Git)
• Broader understanding of system-level design, including embedded firmware, analog interaction, and modelling

Career Growth Philosophy:

At Semtech, we believe that innovation starts with people. We are committed to empowering professional development through mentorship, continuous learning resources, and a collaborative, idea-rich engineering environment.
