About the Role
Role: Senior/Principal Analogue IC Design Engineer – Data Converters & Photonics
Drivers
Department: IC Design / Mixed-Signal Engineering
Location: Bangalore (Hybrid / Onsite / Remote)
Employment Type: Permanent, Full-Time
Level: IC4
The Staff Analogue IC Design Engineer will lead the design of precision mixed-signal building blocks supporting photonics-enabled computing systems. The role focuses on data converters, precision references, biasing circuits, and actuator drivers used to control and tune integrated photonic components.
This position involves system-level architecture and transistor-level design, along with integration of third-party IP blocks to deliver robust mixed-signal subsystems. The engineer will work closely with photonics teams to develop control circuits and monitoring systems for photonic devices.
Key Responsibilities
System Architecture & Circuit Design
● Define system-level architecture for mixed-signal subsystems supporting
photonic control and monitoring.
● Design and implement ADC and DAC architectures, including:
o SAR ADCs
o Pipeline ADCs
o Current-steering DACs
o Resistor-string DACs
● Design precision references and biasing circuits, including:
o Bandgap references
o Current references
o Bias networks
o LDO regulators
Photonics Control Circuits
● Design heater drivers and current sources for thermal tuning of photonic
components.
● Develop monitoring and feedback circuits for photonic actuator control.
● Support electro-optic and thermal tuning mechanisms used in integrated
photonic devices.
Third-Party IP Integration
● Integrate external IP blocks including:
o ADC/DAC IP
o SerDes / PHY interfaces
o Memory blocks
● Map system specifications to IP capabilities and adapt interfaces accordingly.
● Perform subsystem integration verification and sign-off.
Mixed-Signal Verification
● Develop and maintain AMS verification environments.
● Perform simulations using Spectre / AMS Designer.
● Create behavioral models using wreal or Verilog-A.
● Evaluate performance through:
o Corner analysis
o Monte Carlo simulations
o Noise analysis
o Linearity measurements (INL, DNL, SNDR, ENOB)
Test & Characterisation
● Define test strategy and design-for-test (DFT) hooks.
● Support silicon characterisation and production test correlation.
● Assist in silicon validation and performance analysis.
Cross-Disciplinary Collaboration
● Work with photonics engineers to develop models for photonic components such
as modulators and resonators.
● Support development of control algorithms and tuning strategies for photonic
subsystems.
Required Experience & Skills
● MEng, MSc, or PhD in Electronic Engineering, Electrical Engineering, or a
related discipline.
● 15+ years of mixed-signal IC design experience.
● Proven ADC/DAC tape-out experience.
● Experience designing precision references and biasing circuits.
● Practical experience with heater drivers or precision current sources.
● Experience integrating third-party IP into complex mixed-signal systems.
● Strong understanding of top-level AMS verification methodologies.
● Expertise in Cadence Virtuoso design environment.
● Experience with Spectre / AMS simulation flows.
● Scripting capability in Python or MATLAB for modeling and data analysis.
Preferred / Additional Experience
● Familiarity with silicon photonics components, including:
o Ring resonators
o Mach-Zehnder interferometers (MZIs)
o Thermal tuning elements
o Phase shifters
● Experience with calibration and control techniques, including:
o Background calibration
o Trimming
o Temperature compensation
● Knowledge of power management architectures including LDOs and DC-DC
converters.
● Experience designing noise-isolated mixed-signal floorplans.
Benefits
We offer competitive compensation. The base salary range for this role determined
based on location, experience, educational background, and market data.
Salary Range: total compensation goes beyond base salary, it also includes
comprehensive health care plan, retirement savings program, generous time off,
annual performance-based bonus, and other rewards that recognise your impact and
contribution.
Benefits eligibility may vary depending on your employment status and location.
