Immediate hire for Electrical Engineer to join an exciting company and be part of a dynamic team. If you have at least 2–5 years of hands-on experience in RF, Client, Power/PI, or embedded motor control. Own schematics, layout, bring-up, and verification of projects. Design, simulate, and debug RF front ends (e.g., 0.9–6 GHz radios, filters, LNAs/Client, antennas, matching networks). Architect regulated power trees; perform PI analysis (DC drop, impedance targets, ripple, transient response). Implement BLDC/PMSM motor control (FOC, trapezoidal, sensored/sensorless) on MCUs; tune current/velocity/position loops. Develop embedded C/C++ firmware for real-time control, drivers, and diagnostics; integrate with higher-level systems. Drive PCB layout for SI/PI/RF constraints: stackup, return paths, stitching vias, diff-pair routing, creepage/clearance. Plan and execute test campaigns: DVT/EMI/EMC/ESD/thermal; use lab gear (VNA, spectrum analyzer, DSO, power analyzer). Design and validate Battery Management Systems (Client): cell balancing, protection and safety (OV/UV, OC/OT), SoC/SoH estimation, coulomb counting, pack telemetry, contactor/relay control, charging profiles, and thermal management. Write clear documentation: design notes, test reports, and manufacturing/bring-up procedures.
Required Skills:
- BS/MS in Electrical Engineering or related field.
- 2-5 years of professional experience in a device-oriented electrical engineering role.
- Solid foundation in at least one of the following: RF, Client, PCB layout, power/PI, embedded systems, mixed-signal, or motor control.
- Comfortable with test equipment like multimeters, oscilloscopes, spectrum analyzers, signal generators, and vector network analyzers
- Proficiency with at least one of: Altium (schematic/layout), MATLAB/Python for analysis, or SPICE/EM/PI tools.
- Must be strong in PCB and Electrical design
- Ability to own features end-to-end and communicate technical decisions clearly.
Bonus Skills:
- RF: Antenna design/tuning, over-the-air testing, MIMO, coexistence, link budgets, regulatory (FCC/ETSI).
- Power/PI: Buck/boost/PFC, gate-drive design, magnetics selection, thermal design, battery systems, pre-compliance EMI fixes.
- Layout: High-speed SerDes/USB/MIPI, controlled impedance, length matching, HDI, DFM/DFT for volume builds.
- Embedded: RTOS, bootloaders, motor-control libraries (CMSIS-DSP, ST/Xilinx/TI)
- Controls: System identification, FOC tuning, observers, Kalman/PLL techniques, torque/position control.
- Compliance & reliability: HALT/HASS, DO-160/IEC/UL standards, environmental sealing, conformal coat, potting.
