Descripción de la vacante

GreenSight Inc. seeks a hands-on Electromechanical Engineer to lead design and validation of hybrid-electric power and propulsion systems across robotics platforms. You will balance trade-offs in battery sizing, mass, payload, and efficiency while delivering motor and drive hardware integration.

You will perform CAD design, FEA simulations and laboratory bring-up, testing, and optimization of powertrains, ensuring robust performance across flying, driving, swimming, and orbiting systems.

Formación

• BS or MS in Systems, Mechanical, Electrical, or Mechatronics Engineering with 3+ years of professional hardware experience.
• Demonstrated experience modeling system-level trade-offs (e.g., energy storage density, battery sizing vs. payload, duty cycles, weight vs. endurance).
• Proficiency in 3D CAD (SolidWorks or equivalent) for physical machine design and component integration.
• Hands-on experience with engineering simulation software (Altair Flux, ANSYS, MATLAB/Simulink, or equivalent) for FEA or powertrain system modeling.
• Practical experience assembling, wiring, instrumenting, and troubleshooting motor/drive hardware on a test bench.

Responsabilidades

• Hybrid Architecture & Systems Analysis: conduct system-level trade studies to evaluate powertrain topologies, sizing battery capacity, motor power, and engine output against mass, range, and payload limits.
• Electromechanical Machine Design: create 3D CAD models of electric motors, dynamic mechanisms, packaging, and energy generation systems.
• FEA & Simulation: perform electromagnetic, thermal, or structural simulations using FEA software to optimize efficiency maps and sizing.
• Drive & System Bring-Up: wire, tune, and test BLDC/PMSM motor drives and energy management controls on test benches; resolve integration issues.
• Lab Validation & Testing: instrument test rigs using power analyzers, torque sensors, and dynamic loads to validate performance against models.

Electromechanical Engineer (Hybrid Propulsion)

Electromechanical Engineer (Hybrid Propulsion)

Job Description

GreenSight is seeking a hands-on Electromechanical Engineer to lead the system architecture, detailed mechanical design, and physical validation of hybrid-electric power and propulsion systems across our robotics portfolio (flying, driving, swimming, and orbiting systems). In this role, you will balance system-level trade-offs—evaluating battery capacity, weight constraints, fuel energy density, and payload—while executing the physical design, FEA modeling, and laboratory bring-up of electric motors and drives.

Key Responsibilities

• Hybrid Architecture & Systems Analysis: Conduct system-level trade studies to evaluate powertrain topologies (series/parallel hybrid), sizing battery capacity, motor power, and fuel engine output against vehicle mass, range, and mission payload limits.
• Electromechanical Machine Design: Create 3D CAD models of electric motors, dynamic mechanisms, structural packaging, and custom energy generation systems.
• FEA & Simulation: Perform electromagnetic, thermal, or structural simulations using FEA software (Altair Flux, ANSYS, or equivalent) to optimize efficiency maps and component sizing.
• Drive & System Bring-Up: Wire, tune, and test BLDC/PMSM motor drives and energy management controls on physical test benches; resolve multi-component integration issues.
• Lab Validation & Testing: Instrument test rigs using power analyzers, torque sensors, and dynamic loads to validate physical system performance against system models.

Qualifications & Requirements

Minimum Required Qualifications

• Education & Experience: BS or MS in Systems, Mechanical, Electrical, or Mechatronics Engineering with 3+ years of professional hardware experience.
• System Trade Modeling: Demonstrated experience modeling system-level trade-offs (e.g., energy storage density, battery sizing vs. payload, duty cycles, weight vs. endurance).
• 3D CAD & Packaging: Proficiency in 3D CAD (SolidWorks or equivalent) for physical machine design and component integration.
• FEM / Simulation Tools: Hands-on experience with engineering simulation software (Altair Flux, ANSYS, MATLAB/Simulink, or equivalent) for FEA or powertrain system modeling.
• Hands-On Lab Skills: Practical experience assembling, wiring, instrumenting, and troubleshooting motor/drive hardware on a test bench.

Nice-to-Have Qualifications

• Direct experience with hybrid powertrains or internal combustion engine (ICE) co-optimization.
• PCB layout or power distribution hardware experience (Altium).
• Python scripting for test automation or multidisciplinary analysis (MDAO).

Experience

3+ years of non-intern experience

Salary Range: $140,000 – $180,000

Benefits: Stock options, 401(k) with match, full health/dental/vision coverage, 9/80 flexible work schedule, 15 days vacation plus paid year-end shutdown (Christmas to New Year’s).
