What awaits you every day at Quobly

Lead Tech is the guardian of the technical architecture and performance of integrated circuits (ICs). They drive technological choices and oversee the entire implementation process, from initial specifications to GDSII (tape-out). They ensure design robustness against Process, Voltage, and Temperature (PVT) variations in a specific cryotemperature environment. He is also responsible for managing the team, subcontractors, and service providers

Technical Challenges

Core Missions

Architecture & Specification: Define the architecture for critical blocks (ADC/DAC, PLL, PMU, filters, amplifiers, Mux, control …) and translate system requirements into circuit-level specifications.
Design & Simulation: Supervise transistor-level design, corner simulations, noise analysis, and mismatch analysis. A specific point of our designs is the very low operating temperature (100mK to 4 K)
Layout Guidance: Lead layout engineers on matching issues, parasitic coupling, and signal integrity.
Mixed-Signal Verification (AMS): Define verification plans for operation at the interface between the analog and digital domains.
Post-Silicon Validation: Collaborate with test teams to characterize chips in the lab and analyze measurements and tests.
R&D & Innovation: Evaluate new architecture and operating temperature partitioning and protect innovations through patent filing.

Technical Expertise & Skills

Scientific Expertise: Semiconductor Physics, Block Design, Signal Integrity & ESD, Modeling (Verilog-A, MATLAB), Architecture study.

EDA Tools (CAD): Cadence Virtuoso, Simulators (Eldo), Physical Verification (Calibre LVS/DRC), Parasitic Extraction (PEX)

Soft Skills: Extreme scientific rigor, technical decision-making, Managing junior engineers, Foundry and subcontractor communication skills

“Lead” Responsibilities

Design Reviews: Organize and approve critical milestones (Design Reviews) prior to fabrication (Tape-out).
Risk Management: Identify potential failure points regarding performance, yield and long-term reliability.
Foundry and subcontractor Interface: Act as the primary technical point of contact for foundries, partners and subcontractors.
Methodology: Improve internal design flows to increase efficiency and simulation accuracy.
Management : Managing a junior team

Key Performance Indicators (KPIs)

First-Pass Success: Ability to achieve functional silicon on the first revision.
Performance vs. Specs.
Tape-out Deadline Compliance: Delivering the final design vs. the roadmap.
Documentation Quality: Simulation reports and integration manuals.

Candidate Profile

Education: Master’s Degree in Microelectronics or PhD in a related field.
Experience: 8 to 12 years of minimum experience. Several successful tape-outs are mandatory.
Languages: Fluent technical English
