Senior Mixed-Signal IC Designer

Science is a clinical stage, vertically integrated technology company focused on solving some of neuroscience’s hardest questions and most serious unmet medical needs. We work to restore quality of life to those with debilitating conditions for which there are no treatment options, creating devices aimed at restoring vision, cognition, and mobility to patients who have lost it. To support progress across our industry, we provide state-of-the-art components and vertically integrated infrastructure for others to build on via Science Foundry.

We are developing a novel optical interconnect for interfacing with the brain and seeking an experienced ASIC designer with strong background in analog and mixed-signal integrated circuit design, solid track-record in bringing advanced silicon products from idea to product insertion.  As Senior Mixed-Signal IC Designer, candidate should be able to work as a design lead for advanced mixed-signal ASICs, solve technocal challenges that come naturally when you tackle unmet problems in the intersection of biology, biomedical, and implantable circuits.  As a senior IC designer, you will translate broad needs into Silicon specs, propose solutions, execute them technically with the design team, and work with other related groups to make sure that developed chips get inserted into products with success.  While this role requires very strong technical skills and a good track record with successful tapeouts, it also requires skills in terms of project management and guiding team members along the projects.  Ideal candidate should also have strong digital circuit design skills, as most of the chips we develop gets implanted, for which we need to integrate more and more custom digital features in our chips with small foot-print and low power..  

Role responsibilities:

• Work with other groups and teams in the company (Biology and Microfabrication) to translate the multi-disciplinary product requirements into design specifications for chips
• From technical chip specifications, define suitable chip architectures, and from there define building blocks, and distribute it to the rest of the team
• From specifications to tapeout and chip bring-up, own all the major steps.
• Guide the design team, using real design examples.  Delegate as much responsibility as possible to the design team, and help them succeed in their current assignments.  Help them to grow for their next roles.
• Perform detailed project planning and scheduling.  Define milestones, technical review meetings, and deliverables.  Track the progress during design and testing.  The main goal in all these should be to ensure on-time tapeout with first-time-Silicon-success.
• When the team starts struggling due to time pressure or hard to solve technical challenges, help the team by showing alternatives technical solutions at schematic and layout levels, supported by detailed analysis or circuit simulations.
• For chip testing, interface PCB manufacturers, OSATs, and other service providers to fabricate test boards, perform wafer probing, dicing, and assembly 

Key qualifications:

• MSc or PhD in Electrical Engineering, with 10+ years direct design experience as mixed signal IC designer
• Solid background in transistor level analog and mixed-signal circuit design using CMOS technologies, from schematics to layout.
• Solid understanding of active and passive devices available in mixed-signal CMOS technologies.
• Experienced in low-noise and low-power circuit design, including voltage references, biasing circuits, opamps, comparators, digital-to-analog converters (DACs), analog to digital converters (ADCs)
• Experience in noise amplifier (LNA) circuits used in high-fidelity analog front ends to detect very weak signals.
• Experience in transistor level digital circuit design from schematics to layout using schematic and RTL capture.
• Experience in designing, simulating, and verifying analog and mixed-signal designs from schematic entry to tapeout using industry standard IC design tools and design methodologies
• Experience programmable timing generation using Delay-Locked-Loops (DLLs), Phase-Locked-Loops (PLLs), and high-speed counters.
• Experience in high-speed serial data transmit and receive, using serializers and de-serializers, using low-voltage differential signalling (LVDS) transmitters and receivers
• Fluency in high-level circuit modelling using Verilog-A and Verilog for mixed-signal and digital circuits
• Experience in full-chip functional verification using Verilog-A and Verilog
• Familiarity with all the laboratory tools and equipment used for chip bring-up and characterization starting from wafer probing to packaged device testing

Preferred qualifications: 

• Experience digital circuit design from RTL to GDS is a plus
• Familiarity with open-source analog and digital IC design tools is a plus
• Familiarity with FPGA programming for chip testing and IP verification / emulation
