• Build and validate ultra-low-power current budgets to meet multi-day battery-life targets.
• Strong grasp of power electronics and active/passive component behaviour.

Sensor Integration

• Integrate optical biosensing (PPG) AFEs, IMUs, temperature sensors, and haptics; own I²C/SPI interface design and analog front-end layout.

Manufacturing & DFM

• Own Gerber/ODB++ release, fabrication and assembly drawings, panelization, and full manufacturing data packages.
• Prepare and maintain BOMs; evaluate and qualify alternate / second-source components.
• Drive DFM/DFA reviews with fab and SMT/EMS partners; support NPI through EVT/DVT/PVT to mass production.
• Sound understanding of PCB materials, stackups, and component assembly processes.

Compliance, Reliability & Validation

• Apply EMI/EMC, thermal, and mechanical design best practices.
• Support pre-compliance and certification across FCC, CE, BIS, and RoHS, and familiarity with IEC standards for PCB design safety.
• Coordinate with test engineers on board bring-up and PCB validation; run circuit simulations for RF and signal/timing optimization.

Ownership & Collaboration

• Independently manage hardware projects end-to-end, including vendor coordination and delivery of final hardware.
• Collaborate with mechanical engineers to optimize designs and meet project timelines.
• Bring the latest design tools, methodologies, and industry best practices into the team.

REQUIRED QUALIFICATIONS

• Bachelor's or Master's in EEE, Electronics, or equivalent practical experience.
• 4+ years of hands-on hardware / PCB design experience, ideally in consumer electronics or wearables.
• Proficiency with a leading schematic and PCB toolchain (OrCAD / Allegro preferred).
• Proven track record taking a product from schematic through layout to volume production.
• Working knowledge of power electronics and active/passive component selection.
• Familiarity with global certifications (FCC, CE, BIS, RoHS) and IEC PCB safety standards.

PREFERRED / BONUS

• Experience with miniaturized high-density or rigid-flex designs.
• RF design experience (2.4 GHz / BLE, NFC, antenna tuning and matching).
• EMI/EMC design and pre-compliance testing experience.
• Low-power / battery-operated wearable product experience.
• Familiarity with reliability methods (DFMEA, derating) and RF / signal-timing circuit simulation.

Role: Head of Engineering

Level Five Cartronics | Fabless Automotive Semiconductor Design

Location: MG Road, Bengaluru, Karnataka, India (On-site)

About Us

Founded by serial Entrepreneurs, Level Five Cartronics is a fabless semiconductor design company headquartered in Bengaluru, building automotive-grade Power Management ICs (PMICs), high-precision oscillators, and high-performance phase-locked loops (PLLs) for the next generation of vehicle electronics. Our portfolio centres on low-EMI power delivery — including spread-spectrum EMI suppression — and low-jitter clocking and interface solutions for safety-critical solutions and infotainment systems. We design DC-DC converters, LDOs, and clock distribution networks (including low-jitter PCIe Gen 4, 5, and 6 buffers) in CMOS and BCD high-voltage processes across the 55nm, 90nm and 180nm nodes. We own our products end to end, from architecture through silicon characterization and productization, as part of India's growing fabless semiconductor ecosystem.

The Role

We are looking for a hands-on Head of Engineering, based at our Bengaluru headquarters, to lead our analog/mixed-signal design organization. This is a senior leadership position for an engineer who has personally taken complex automotive power, clocking, and high-speed interface products from concept to high-volume production — and who can build, mentor, and scale the cross-functional team that does it again and again.

You will set the technical direction for our PMIC, oscillator, PLL, and PCIe buffer roadmaps, own design quality and tape-out readiness, and partner closely with characterization, product, and test engineering to ensure every product meets stringent automotive reliability, jitter, and EMC requirements.
