Sr/Staff Digital Design Engineer
$154,000 USD yearly
Develop ASIC modules integrating silicon photonic communication and compute technology.
Originally posted 7 November 2026 by the employer.
About the role
Lightmatter is hiring a Digital Design Engineer to develop an ASIC for artificial intelligence computing architecture. The role integrates silicon photonic communication and compute technology into digital accelerator design.
What you'll do
- Develop RTL (SystemVerilog) modules with DFT considerations for IC development.
- Debug complex logic and mixed signal simulations using industry-standard EDA tools.
- Integrate silicon photonic communication and compute technology into digital accelerator design.
- Collaborate with Architecture, Design Verification, Physical Design, Photonic, Analog, and Software teams to realize high-performance, low-power designs in advanced technology nodes.
- Create design specifications, module documentation, and manage RTL implementation to achieve functionally correct, performant designs.
What you'll need
- Bachelor’s degree in Electrical or Computer Engineering (or related fields).
- At least 5 years of experience in ASIC design or a similar high-speed chip design with multiple successful tape outs.
- Proficiency in SystemVerilog or Verilog for digital logic design.
- Experience debugging complex logic and mixed-signal simulations using EDA tools such as Synopsys VCS, Cadence Xcelium, Questa, or equivalent mixed-signal co-simulation environments.
- Track record of delivering high-performance, low-power digital designs in advanced semiconductor process nodes.
Nice to have
- Master's degree in Electrical or Computer Engineering (or related fields).
- Experience in communication protocols such as PCIe.
- Knowledge of processor design, accelerators, and/or memory hierarchies.
- Exposure to silicon photonics (SiPh), optical compute/interconnect architectures, or electro-optic interface integration.
- Scripting skills in Python, Perl, Tcl, or Bash to automate simulation and design workflows.
- Experience interfacing digital logic directly with analog mixed-signal (AMS) IP, such as SerDes, ADCs/DACs, or optical transceivers.

How we counted: 1070 open Digital/RTL Design (RTL Design) roles from 105 employers tracked in the SemiconductorJobs index, counted 14 Nov 2026. Specialty figures count only roles carrying this exact specialty label, so an employer's related work in neighbouring specialties is not included there, and is counted in the wider Digital Design & Verification family row. Days are counted from when our index first saw each posting, not from the employer's original posting date.
