As a global leader in cutting-edge silicon design and semiconductor innovation, arenaflex is constantly pushing the boundaries of what's possible in computing, mobile devices, and beyond.

We are currently seeking talented and motivated Custom Circuits Design Engineers to join our elite silicon design team on a part-time basis. This is a unique opportunity to work on groundbreaking ASIC (Application-Specific Integrated Circuit) designs that power the world's most advanced electronic devices. If you're passionate about circuit design, thrive on technical challenges, and want to be at the forefront of semiconductor innovation, arenaflex is the place for you.

As a member of our Digital organization at arenaflex, you'll take innovative and progressive ideas and determine how to transform them into reality. You and your team will apply engineering fundamentals from the ground up, bringing thought-provoking concepts to life. Your contributions will be remarkable, often literally groundbreaking. Join us, and you'll help design the instruments that allow us to deliver client experiences they've previously never imagined.

About the Role: Custom Circuits Design Engineer

You will be part of an exciting silicon design group responsible for crafting next-generation ASICs. We have an exceptional opportunity for Circuits Engineers to design advanced custom digital megacells—including SRAM memories, on-chip sensors, ML accelerators, and data path components—used in high-performance, low-power System-on-Chip (SoC) solutions.

This role offers the chance to work at the center of our SoC design effort, collaborating across all disciplines with a significant impact and playing a pivotal role in bringing functional products to millions of customers quickly. You'll have the opportunity to coordinate and develop groundbreaking ideas while working with a team of dedicated engineers.

Key Responsibilities

• Design and Develop Custom Circuits: Create innovative custom circuits to improve chip power efficiency and performance across various silicon products.


• Collaborate Cross-Functionally: Work closely with power teams, physical design (PD) teams, and other engineers to define specifications and requirements for new circuit implementations.


• Perform Comprehensive Design Analysis: Execute design, analysis, modeling/simulation, circuit-level specifications, schematic capture, spice simulation/corner verification across PVT (Process, Voltage, Temperature), statistical design, functional verification, and silicon bring-up.


• Layout Integration: Work closely with the layout team to complete designs and oversee layout quality to ensure optimal performance.


• Drive Design Methodology: Develop and drive circuit strategies to achieve the highest design quality metrics across all products.


• Silicon Debug & Validation: Conduct experiments during silicon debug, manufacturing, and data analysis; utilize scripting to efficiently process ATE (Automatic Test Equipment) data.

Essential Qualifications

• Education: Bachelor's degree in Electrical Engineering, Computer Engineering, or related technical field.


• Experience: Minimum of 3 years of relevant industry experience in circuit design.


• Advanced Technology Node Expertise: Proven design experience in cutting-edge technology nodes.


• Low Voltage/Low Power Design: Strong experience in low-voltage and low-power custom circuit design.


• Deep Submicron Knowledge: Comprehensive understanding of deep submicron device physics, leakage mechanisms, and technology interactions with device behavior.


• Device Characterization: Strong understanding of device matching, device noise sources (1/f, thermal), and external noise sources (supply, jitter), and their impact on high-precision circuits.


• Scripting & Automation: Proficiency in scripting languages (Python, Perl, or similar) and CAD automation tools.


• Industry Tools: Knowledge of industry-standard circuit and design tools.

Highly Desired Skills & Expertise

While not required, experience in one or more of the following areas would be highly advantageous:

• AI/Machine Learning Accelerators


• SRAM Circuit Design


• Non-Volatile Memory Technologies


• Weak/Strong Inversion Circuits


• Ultra-Low Power Amplifiers


• DC/DC Converters


• Advanced On-Chip Sensors
