Electrical Engineer

About Us 

Chariot Defense is a defense technology company that designs and manufactures a family of power products for the U.S. military and its allies. We believe that credible deterrence of armed conflict and winning if deterrence fails, requires more than just the best drones, sensors, weapons, electronic warfare systems, and command & control capabilities. Those critical components will require sustained electric power in austere and resource-constrained environments. Moreover, military units must be able to turn off the trucks and generators that generate this power to hide and survive. In other words, power generation must be decoupled from power consumption. Chariot Defense’s products enable exactly this capability, allowing U.S. and allied militaries to be more lethal and survivable. We hope you will join us on this mission.

About the Role 

Chariot Defense is seeking a highly motivated and skilled Electrical Engineer to join our engineering team, reporting to the Head of Electrical Engineering. In this role, you will conceptualize, design, develop, and test advanced energy storage and power electronic systems. You will work across multidisciplinary engineering and design teams to ensure our systems meet stringent MIL-STD performance, reliability, and security requirements for deployment in demanding environments, performing critical missions. 

Key Responsibilities 

• Design & Development: Create schematics, layouts, and circuit designs for low- and high-voltage power electronics systems coupled with advanced energy storage, management, and safety systems, optimizing for stable circuit dynamics, power efficiency, latency, electrical safety and system protection, and abuse loading cases, to name a few. 

• Testing & Validation: Perform circuit simulations, bench testing, and system-level validation to ensure compliance with military and industry standards. 

• System Integration: Collaborate with mechanical, thermal, software, and systems engineers to integrate electronics into cohesive and elegant products, carry out electrical and system integration, and manage tight coupling between electrical IO’s and firmware behavior. 

• Reliability Engineering: Apply design-for-reliability practices, including EMI/EMC mitigation, ruggedization for harsh environments, and thermal management. 

• Documentation & Compliance: Generate technical reports, test plans, and ensure adherence to MIL-STD and other defense specifications. 

• Lifecycle Support: Provide engineering support throughout the product lifecycle, from concept through field deployment and sustainment. 

What We’re Looking For 

• Top-notch engineering intuition and first principles thinking toward designing complex products that function seamlessly for your customer, taking both an engineering/ technical, and product/ customer approach, to strike the optimal balance. 

• Able to independently identify critical information or priority gaps and apply effort toward closing those gaps. 

• Undaunted by imperfect, incomplete or absent datasets or information, and capable of making sound, comprehensive, and swift first-principled decisions to achieve a product end-state that meets and/or exceeds the need of the hour.

• Not satisfied by superficial explanations of a problem or “band-aid engineering”; seeks persistently to find the specific root cause through data-driven methods, and resolve failures or recurring issues, so they can be mitigated to prevent future such instances. 

• Gratified by helping your peers succeed, building a robust team culture, and propagation deep camaraderie amongst your peers; seeks to break down information silos by collaborating rigorously with others to solve problems, share knowledge, and provide input. 

Qualifications 

Required: 

• BS or MS in Electrical Engineering, or related degree.
• 3+ years of experience in end-to-end circuit design, component selection and specification, electrical architecture trade-offs, ASIL redundancy/ functional safety, embedded systems troubleshooting, and electronics testing.
• Proficiency with CAD tools (preferred, Altium), simulation software (preferred, MATLAB/Simulink/Spice)
• Competence with test equipment such as oscilloscopes, function generators, low and high voltage programmable power supplies, spectral, logic, and impedance analyzers, debuggers, voltage probes, current clamps, and automation of tests, reflow techniques, soldering, connector selection and integration etc.
• Fluent in CAN BUS protocols (preferred, J1939, CANOPEN) and other low-voltage networking protocols.
• Familiarity with MIL-STD, DO-160, or other automotive, defense, and aerospace standards.
• Strong problem-solving and troubleshooting skills. 

Preferred: 

• Experience designing and working directly with low and high voltage energy storage systems, high current/ high voltage power distribution, and voltage regulating power electronics.
• Experience with advanced circuit modeling tools such as LTSpice and multiphysics  systems such as Comsol, and familiarity with common and less frequent complex circuit dynamics (e.g.: oscillations, ringing, ground bounce etc.)
• Experience designing, and debugging, various end-point nodes on an electrical grid such as motors, sensors, resistors, other inductive/ capacitive/ resistive loads
• Experience designing low-side and high-side circuit switches, half and full bridges, advanced noise filters and power stabilizers, fly back diode circuits, passive and active discharge systems etc.
• Experience with critical managing radiated emissions for minimizing any RF signatures, and designing for immunity from external RF spectra, and some exposure to broadband amplifiers, antennas, near-field probes etc.
• Experience in industries/applications requiring high-reliability embedded power electronics operated in austere environments.
• Familiar with U.S. and NATO operational requirements, particularly the Tactical Microgrid Standard. 

Role Requirements

• This position is an onsite role based in Chariot Defense’s San Bruno, CA, office. 

• Willingness to support 10% travel, domestically and internationally, as well as work extended and weekend hours, when necessary 

• Able to work on your feet for extended periods in a shop setting. 

• Able to lift and carry 50lbs. 

A reasonable estimate of the current salary range is $130,000-$180,000 annually. Compensation packages also include early-stage equity and access to company-sponsored benefit plans. 

Individual compensation packages are based on geographic location, scope of the role, relevant experience, and the ability to deal with complexity and problem solve within our organization, among other factors. 

All employees are required to provide proof of authorization to work in the U.S. within their first 3 days of work. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.  

Any unsolicited resumes/candidate profiles submitted through our website or to personal email accounts of employees of Chariot Defense are considered property of Chariot Defense and are not subject to payment of agency fees.
