Working at Tempo

Tempo is a lean organization working on exciting challenges, and the people who thrive here share a few things in common beyond their technical skills.

• Clear, direct communication: You professionally say what you mean, lead with empathy, use tact, ask when you're unsure, and keep the people around you informed without being asked. At a company our size, communication gaps are expensive, and good communicators add to success and efficiency!
• Low-ego helpfulness: You're willing to jump in on work that isn't strictly yours, whether that's helping a teammate debug something, lending a hand in the shop, or flagging an issue you noticed outside your lane. No one here succeeds in a silo.
• Intellectual curiosity: You're genuinely interested in how things work, not just your piece of it, but the broader system. Tempo sits at the intersection of chemistry, mechanical engineering, power electronics, and software; the more you understand about the whole, the more valuable you become.
• Business awareness: You understand that your work exists in a business context. You think about cost, timeline, and tradeoffs—not just technical elegance—and you make decisions accordingly.
• Comfort with ambiguity: Processes here are still being built. You can make progress without a perfect playbook, and you know when to ask for direction versus when to use your judgment and move forward.
• Accountability: You own your outcomes, including the misses. When something goes sideways, the instinct here is to fix it and learn from it, not to explain why it wasn't your fault.

This job description is intended to provide a general overview of the position and is not an exhaustive list of duties, responsibilities, or qualifications.

Tempo reserves the right to modify, add, or remove responsibilities as business needs evolve.

Employees may be asked to perform duties outside of those listed above from time to time.
