Principal ASIC design engineer

Principal ASIC design engineer 3000 2000 XMOS

This role reports to the Director of Hardware Design, based in our Bristol office. Your Responsibilities will include:

  • Close partnership with and interface to the Architecture and System S/W teams, contributing to the top-level IC functional specification to company sign-off 
  • Block and system specification through to timing-clean Verilog RTL
  • Interface to the Physical Implementation team in support of closing timing and block/chip finishing
  • Support of PE and hardware bring-up teams with debug, once the chip is back from 1st manufacture. 

You’ll need to be self-directed, proactive and able to work independently and you’ll enjoy solving day-to-day problems with limited direction. 

About XMOS

We’re a global business, headquartered in Bristol, with offices across Asia and the United States; and we’re backed by some of the best names in high tech venture capital.

With a 10-year pedigree in Hi-Res and multichannel USB audio solutions, XMOS is at the forefront of the far-field voice interface market, with the most qualified, most comprehensive range. Adopted by leading brands, our high-performance, easily integrated solutions are transforming consumers’ interactions with everyday devices.

As a deep tech company working to develop more natural human machine interfaces, we’re always looking for questioning, flexible and determined people to help make that happen. Ours is a learning environment, which means we hire for capability and potential – and help you to achieve your best.

About our technology

XMOS is a fabless semiconductor company with a unique micro-controller design, underpinned by our own in-house tools.

Our approach to multi-core, highly parallel stream processing enables our software team to develop highly efficient “at the edge” intelligent sensor applications.

Today, we deliver best in class voice capture – detecting voice commands accurately, from across the room – even in busy environments when the person is speaking softly. And we’re building for a more natural human machine interface tomorrow.

Who we’re looking for

XMOS has ambitious plans for its next generation of ICs and is looking for energetic and versatile verification engineers to join the growing team. Working in a ‘start-up’ environment, you will participate in and influence all aspects of verification, from methodology to tools, validating from block to chip level.

You will have a proven track record in the design of complex digital ICs, with demonstrable skills in ASIC Hardware Design, from specification to RTL, including hands-on expertise in: 

  • Simulation; 
  • Timing, area & power awareness; 
  • Synthesis; 
  • Working with 3rd party IP and macro vendors (such as PLL, POR, PHY, SRAM, OTP, USB, MIPI); 
  • Verification, directed and random test; 
  • Coverage closure; 
  • Version and change control management; and  
  • In support of your design effectiveness, you will be familiar with tool flow automation, with a good understanding of scripting languages. 

You will also have experience in Chip Level Integration, including: 

  • Pad & complex IO structures & interfaces; 
  • Design-for-test; and  
  • Some experience of post tape-out silicon bring-up and debug. 

Your Technical Experienceshould include a working knowledge of processor architecture and processor design, with an appreciation of hardware and low-level software interoperation, such as how assembly code may be used during verification.   

Whilst this is a hands-on role, it would be beneficial if your background includes some leadership experience, be it of small design teams, working with 3rd party IP providers or directing sub- contractors.  You will also have participated in project planning and conducted project and release-readiness reviews.
