$13,131 more — $139,131 — moves this role to Level III and 3 lottery entries. That figure is inside the range the employer already advertised.
Based on the DOL prevailing wage for this occupation and worksite, a base salary of $139,131 would place this position at wage Level III. That figure is within the posted range, and I'd like to target it. This role classifies under "Industrial Engineers" for prevailing-wage purposes.

About the role
- Our work spans battery cells, pack architecture, mechanical integration, electrical systems, battery management, thermal management, charging, safety, validation, and manufacturing.
- You will work hands-on with cells, modules, packs, test systems, and complete robots, using data from laboratory testing and real-world operation to continuously improve performance, safety, lifetime, and manufacturability.
- Improve battery energy density, power capability, thermal performance, cycle life, reliability, and serviceability through iterative engineering and testing
Responsibilities
- We're building humanoid robots that work in home - doing the chores, handling the tasks, and giving people their time back.
- NEO is our flagship - a home robot designed to move, learn, and operate in the real world alongside real people.
- We're scaling, we're hiring with intention, and we need people who want to build something that will genuinely change how humans spend their time - safely creating abundance for all.
- We partner closely with Electrical, Mechanical, Controls, Embedded Software, Reliability, Manufacturing, and Supply Chain teams to deliver battery systems that perform safely and consistently in real-world environments.
- Build the battery systems that keep humanoid robots moving.
- You will own critical elements of NEO's battery system from architecture and component selection through design, prototyping, characterization, validation, and production.
- You will develop compact, lightweight, safe, and reliable battery solutions capable of supporting the dynamic power requirements of a humanoid robot operating every day around people.
Requirements
- Bachelor's degree in Mechanical Engineering, Electrical Engineering, Chemical Engineering, Materials Science, or a related engineering field
- Strong understanding of lithium-ion cell performance, charging and discharging behavior, degradation, thermal behavior, and safety
- Experience with battery pack architecture and integration, including cells, interconnects, sensing, protection, thermal management, and mechanical packaging
- Experience defining and executing battery characterization and validation testing
- Experience with battery safety, fault analysis, failure modes, and design mitigation strategies
- Experience collaborating with electrical, mechanical, embedded software, manufacturing, quality, reliability, and supply chain organizations
Skills
- Experience with cylindrical, pouch, or prismatic lithium-ion cells and cell selection and qualification
- Experience with Battery Management Systems (BMS), including cell monitoring, state estimation, protection strategies, and fault handling
- Experience with battery thermal management, thermal modeling, cooling strategies, and temperature sensing
- Experience with cell aging, cycle-life modeling, State of Charge (SOC), State of Health (SOH), and performance degradation analysis
- Familiarity with battery safety and transportation standards such as UL, IEC, and UN 38.3
- Experience supporting battery systems through NPI, qualification, reliability testing, and high-volume production ramp
Compensation
- $126,000 - $181,000 + Equity
Benefits

- Flexible Spending Accounts (FSA) and Health Savings Accounts (HSA) options
- Commuter benefits (transit and parking)
- Short-term and long-term disability, and life insurance
- Employee Assistance Program (EAP) for mental health, financial, and personal support
Company info
- Design and release production-ready battery systems that meet energy, power, weight, volume, thermal, safety, reliability, cost, and manufacturability requirements
- Develop battery pack architectures integrating cells, busbars, interconnects, sensing, protection, BMS hardware, thermal management, enclosures, and structural interfaces
- Define and validate cell and pack performance requirements across charge, discharge, peak power, temperature, aging, and real-world robot duty cycles
- Develop characterization and validation methods for cells, modules, packs, charging systems, and battery safety
- Identify battery failure modes through testing and data analysis and drive design improvements and corrective actions
- Support battery hardware through prototype builds, design validation, NPI, supplier qualification, and production ramp
- Partner closely with Electrical, Embedded Software, Mechanical, Controls, Reliability, Manufacturing, and Supply Chain teams to deliver fully integrated energy systems
- Strong engineering fundamentals across battery systems, electrochemistry, electrical systems, thermal management, and hardware development
- Ability to design fixtures and test equipments.
