Oakland, CA, USA
Posted on Thursday, May 4, 2023
The Thermal Management / Mechanical Engineer will design and build high-performance, high-power mechanical systems for a novel vehicle charging technology poised to transform the electric semi-trucking industry. The Thermal Management / Mechanical Engineer will work as part of a small team of talented engineers developing critical enabling technologies, demonstrating breakthrough performance characteristics, and preparing the design for production. These contributions are foundational for Jaro’s growth as we work to address a $20B emerging market and a huge, unresolved source of climate emissions and urban pollution.
Level of job title can vary based on skills and experience.
This role requires at least 50% onsite presence at our Oakland, CA location.

What you'll do:

  • Model, design, and test a thermal management system for a novel, high-power EV charging system.
  • Influence overall system design to deliver superior performance in rough environments with high reliability.
  • Work closely with systems engineers and electrical engineers early in the design process to align on thermal performance requirements and develop a robust, integrated thermal design solution.
  • Deliver system designs optimized across multiple dimensions including safety, cost, environmental compliance, industrial packaging, manufacturing and assembly, reliability, availability, and product performance.
  • Perform thermal simulation and system modeling.
  • Fabricate test bucks and prototypes to demonstrate performance across a variety of environmental conditions.
  • Contribute to design for manufacturing and pilot production ramp.
  • Contribute to and execute against an engineering roadmap that manages technical risks and produces high-value deliverables on schedule.
  • Collaborate with other engineering specializations to ensure safe and optimized system design and functionality.
  • Contribute to early team culture, strategy, and organization for the Engineering team and the broader Jaro team.

What you'll bring:

  • At least 3 years of relevant, professional work experience.
  • Experience designing, testing, and building industrial-grade, thermal management systems for rough and dynamic environments, including component design, system optimization, industrial safety, and/or regulatory compliance.
  • Experience with high-voltage (at least 500 VDC) power electronics system packaging and thermal optimization.
  • Familiarity with electronics system protection trade-offs and environmental compliance requirements.
  • A track record of successfully deploying new thermal system designs in commercialized industrial (vs. consumer) products, with experience in early product development (concept through pre-production).
  • Think creatively and opportunistically to solve unusually hard problems efficiently.
  • Think clearly about technical risks and how to manage them.
  • Value diverse ideas, backgrounds, and problem-solving strategies.
  • Communicate effectively to share learnings and make clear decisions.
  • Thrive in a nimble, small-team environment with significant individual autonomy.
You're encouraged to apply even if your experience doesn't precisely match the job description. We welcome diverse perspectives and backgrounds, and your skills might be a great fit for this or other roles!
