Principal/Senior Digital IC Design Engineer

We are seeking a Principal or Senior Digital IC Design Engineer to take a leading role in the design and verification of advanced digital and mixed-signal optical devices. You will work closely with product definition teams to shape chip architecture, define detailed specifications, and deliver RTL designs through to tape-out. This role requires a high-energy, self-motivated engineer with strong communication skills and a passion for solving complex digital IC challenges. You will have the opportunity to influence key architectural decisions, mentor junior engineers, and contribute to designs that are deployed in mass production. Primary Responsibilities

Collaborate with the product definition team to develop high-level requirements for new devices. Translate architecture documents and high-level specifications into detailed design specifications. Create RTL designs using Verilog or VHDL, perform block and top-level simulations, and apply timing constraints. Develop comprehensive verification plans to fully validate designs through simulation. Behavioural modeling of complex analogue functions to support mixed-signal integration. Execute synthesis, place & route, DFT insertion, timing closure, and ATPG for SCAN test. Work closely with layout engineers to ensure designs meet LVS, DRC, and timing requirements. Support design verification environment definition, implementation, and debugging. Mentor and guide junior team members to support technical growth and knowledge sharing.

We’re seeking a talented Principal or Senior Digital IC Design Engineer with a strong background in digital IC design who thrives in collaborative, high-performance teams. You will take ownership of the digital design lifecycle, influence architectural decisions, and help deliver next-generation mixed-signal optical devices. Minimum Qualifications

Principal: 10+ years experience in digital IC design from specification through to tape-out. Senior: Minimum of 7+ years of relevant digital IC design experience.

Required for Both Levels

Proficiency in Verilog or VHDL for RTL design and verification. Experience in low-power, energy-efficient digital logic design. Knowledge of scripting languages such as Perl, TCL, or similar. Expertise with digital design tools for synthesis, place & route, timing closure, DFT insertion, and ECO from Synopsys or Cadence. Experience with CMOS process technologies from 180 nm down to 28 nm or below. Proven track record of delivering multiple designs into mass production. Degree in Electrical/Electronic Engineering or related field (BSc/MSc/BEng/MEng/PhD).

Desired Qualifications

Verification experience with SystemVerilog, C, or Vera. Exposure to mixed-signal verification or FPGA design.

Opportunity to take a principal or senior role in shaping the architecture of next-generation mixed-signal optical devices. Work on designs that will be deployed in mass production and define the future of high-speed optical signal integrity products. Collaborate with a highly skilled, innovative R&D team in a fast-paced, technology-driven environment. Influence product decisions, mentor the next generation of engineers, and help build Semtech’s technical leadership in digital IC design.
