Role Summary

We are seeking an Expert Analog Hardware Engineer with deep experience in designing, simulating, and validating high-performance analog and mixed-signal electronic systems. The candidate will lead product-level hardware architecture, own critical analog blocks, and guide junior engineers while working closely with cross-functional teams in digital, firmware, RF, and mechanical engineering.

Key Responsibilities

Analog & Mixed-Signal Circuit Design

- Design and optimize analog building blocks such as:

• precision amplifiers (op-amps, instrumentation, transimpedance, low-noise)
• ADC/DAC front-ends and signal-conditioning circuits
• filters (active/passive, low-noise, anti-aliasing, reconstruction)
• power stages (DC-DC, linear regulators, low-noise supplies)
• sensor interfaces (bridge, piezo, current/voltage sensing)

- Develop architectures for low-noise, low-distortion, and high-accuracy circuits.

Simulation & Analysis

• Perform SPICE simulations (AC, transient, noise, Monte-Carlo, corner analysis).
• Conduct signal integrity (SI), power integrity (PI), and noise analysis.
• Model real-world component behavior (parasitics, temperature effects, tolerances).

Hardware Development

- Create complete schematics, BOMs, and documentation.

- Work with PCB layout engineers; provide guidelines for:

• grounding schemes
• high-speed/low-noise routing
• impedance control
• thermal design
• isolation and safety compliance

- Perform worst-case analysis and derating for reliability.

Prototyping & Validation

- Bring-up and debug boards using:

• oscilloscopes, spectrum analyzers, VNAs, logic analyzers
• precision DMMs, SMUs, network analyzers

- Validate performance vs. design specifications.

- Conduct design verification testing (DVT) and root-cause analysis of issues.

Cross-Functional Collaboration

• Collaborate with embedded firmware and digital hardware teams.
• Support manufacturing and production test development.
• Review component choices for supply chain resiliency and cost optimization.

Compliance & Certification

- Ensure designs comply with EMI/EMC, safety, environmental, and regulatory standards:

• IEC/UL standards
• CISPR/EN noise emission standards
• ESD/Surge/ESD immunity

- Support certification processes with test labs.

Required Qualifications

- Bachelor's/Master's in Electrical/Electronic Engineering.

- 5+ years proven experience in analog/mixed-signal hardware design.

- Strong expertise in:

• analog circuit theory
• low-noise design
• precision measurement systems
• power electronics fundamentals

- Deep understanding of real-world effects: EMI/EMC, grounding, parasitics, layout impacts.

- Hands-on experience with lab test equipment.

- Proficiency in schematic & simulation tools (e.g., Altium, OrCAD, LTspice, PSpice).

Preferred Qualifications

• Experience with high-voltage/high-power analog systems.
• Experience with RF front-ends or high-speed ADCs/DACs.
• Experience designing for harsh or industrial environments and military environments.
• Familiarity with Python/Matlab for test automation.

Soft Skills

• Strong problem-solving and analytical thinking.
• Excellent documentation and communication.
• Ability to independently drive complex hardware projects.
• Attention to detail and passion for high-quality engineering.
