4. Drive designs across CMOS and BCD high-voltage processes at 55nm, 90nm and 180nm, from specification through tape-out and qualification.

5. Set and enforce design methodology, review gates, and tape-out criteria; review schematics, layout, and verification plans personally where it matters.

6. Partner with characterization engineers on lab bring-up, silicon debug, and correlation of measured results to simulation.

7. Work side by side with product engineers on productization, test development, yield, and sustaining.

8. Build and lead cross-functional teams; recruit, develop, and retain top analog and layout talent in India's semiconductor talent market.

9. Be a technical authority and final escalation point for difficult design and silicon issues.

What You'll Bring

- Minimum of 12 years (preferably more) of experience in analog/mixed-signal design, layout, and productization.

- Demonstrated track record of taped-out databases and shipping full products in volume, not just isolated blocks.

- Deep expertise across the full flow: schematic design, layout, and lab characterization (understanding how each one constrains the others).

- Hands-on design of DC-DC converters and LDOs in CMOS and BCD high-voltage processes.

- Expertise in clocking and interfaces: deep understanding of low phase noise design, Fractional-N PLL architectures, and low-jitter PCIe Gen 4, 5, and 6 clock buffers/drivers.

- Experience with PMICs, oscillators, and spread-spectrum / EMI suppression techniques.

- Strong working knowledge of the 55nm, 90nm and 180nm process nodes.

- Extensive experience with Cadence EDA tools across the design and verification flow.

- Mixed-signal behavioral modeling in Verilog (Verilog/Verilog-AMS).

- Proven history of working closely with characterization and product engineers through bring-up and ramp.

- Demonstrated success building, leading, and recruiting cross-functional engineering teams.

Nice to Have

- Automotive qualification experience (AEC-Q100, ISO 26262 / functional safety awareness).

- Strong EMC/EMI design and measurement background.

- Experience scaling an engineering organization in a fabless environment, ideally within India's semiconductor ecosystem.

Why Level Five Cartronics

You'll own real products in a fast-moving automotive market, work across the full design-to-silicon flow, and shape the engineering culture of a growing fabless company based in Bengaluru — one of India's leading semiconductor design hubs.
