The job description

Tech stack. ROIC design, photodiodes, transimpedance amplifiers (TIA), low-noise front ends, chopper stabilization, sensor interfaces, Cadence Virtuoso, Spectre

About the role

You will join a sensor semiconductor company designing readout ICs that turn faint physical signals into clean digital data. The team builds the analog front ends for image sensors, LiDAR, and industrial sensing: photodiode interfaces, TIAs, and precision readout chains. This role matters because the sensor is only as good as its readout: your noise floor and dynamic range decide what the system can actually detect. New sensing modalities appear every year, and the readout team is usually the first to touch them. The work spans consumer, automotive, and industrial sensing, so no two projects look alike.

What you will achieve

Ship readout chains that hit noise, bandwidth, and dynamic-range targets on first silicon across illumination and temperature corners
Design transimpedance amplifiers and front ends optimized for specific detectors, balancing gain, noise, and power for each sensor type
Cut input-referred noise through chopper stabilization, correlated double sampling, or auto-zero techniques matched to the signal band
Deliver sensor interfaces with calibration and trimming that hold accuracy over lifetime drift and process variation
Drive electro-optical characterization with customers' detectors, correlating measured responsivity and dark current against your models
Support system integration, resolving grounding, supply, and timing interactions between your ROIC and the customer's sensor assembly
Prototype readout concepts for emerging sensor types, giving the company early-mover advantage in new markets

What you will bring

Must-haves

2-5 years designing sensor interfaces or readout ICs with at least one shipped sensing product
Strong low-noise design skills: you can budget noise across a signal chain and know which stage dominates
Design experience with transimpedance amplifiers, charge amplifiers, or precision sensor front ends
Understanding of photodiode and detector behavior: capacitance, dark current, responsivity, and their circuit implications
Proficiency in Cadence Virtuoso and Spectre, including noise analysis and transient simulation of sampled systems
Familiarity with offset and 1/f noise mitigation: chopping, auto-zero, and correlated double sampling
B.S. or M.S. in Electrical Engineering with an analog or sensor circuits emphasis

Nice-to-haves

Experience with image sensor, LiDAR, or time-of-flight readout architectures
Familiarity with pixel-level design or large array readout considerations
Prior work with MEMS or capacitive sensor interfaces
