Summary Generated by Built In
We are seeking a Chief of Staff to partner closely with our CEO and executive leadership team. This is a high-impact, strategic role designed for someone who thrives in a dynamic, fast-paced environment and has a proven ability to drive clarity, alignment, and execution across an organization. 

The Chief of Staff will work closely with the CEO and maintain a dotted-line relationship with the COO, ensuring Arbor’s top priorities are well-defined, resourced, and delivered. This role manages the company’s operating cadence, drives communication from the executive team to the broader organization, and ensures leadership focus is consistently directed toward the initiatives that matter most. The Chief of Staff will also lead investor and board communications, as well as shape the narrative for company-wide milestones such as fundraising, product achievements, and other high-visibility activities. 

This is an onsite role in El Segundo. 

Arbor is a team of engineers, scientists, and builders focused on creating the next generation of clean energy systems. Our work combines high-efficiency turbomachinery, advanced combustion, and modular design to deliver zero-emission, fuel-flexible power at scale. We’ve drawn from aerospace and industrial expertise to meet the challenge of surging electricity demand—and to offer a solution that installs faster, performs better, and costs less than conventional alternatives. We’re designing energy systems that can evolve with the world’s needs.

Responsibilities

  • Partner with the CEO (with a dotted line to COO) to drive strategic planning cycles, ensuring priorities are well-defined, communicated, and executed. 
  • Translate strategic objectives into clear operating plans and track progress against key results. 
  • Drive executive-level communications to the broader organization, including weekly CEO updates, all-hands narratives, and change-management updates. 
  • Lead investor and board communications: develop board decks and support fundraising diligence. 
  • Communicate high-visibility company activities (fundraising, product milestones, organizational changes, customer wins) to the organization with clarity, context, and alignment. 
  • Ensure cross-team visibility through concise status updates, risk registers, and dashboards that inform action. 
  • Act as a connector across teams, ensuring alignment between leadership and functional leads, and proactively removing roadblocks. 
  • Conduct research and analysis to support informed decision-making and long-term planning. 

Requirements

  • Bachelor’s degree required; MBA or equivalent experience strongly preferred. 
  • 5+ years of experience in management consulting, investment banking, venture capital, or strategy/operations roles at a high-growth company (ideally a strong background spanning both analytical and operating roles). 
  • Experience supporting investor relations, fundraising, or board management. 
  • Proven ability to drive complex projects from ideation through execution. 
  • Exceptional analytical, organizational, and problem-solving skills. 
  • Strong written and verbal communication skills with experience presenting to senior stakeholders. 
  • Exceptional relationship-building and influencing skills, sound judgment, and ability to operate with discretion. 
  • Familiarity with hardware, renewable energy, or deep-tech environments.

What We Do

At Arbor, we’re sustainably powering the present while erasing emissions of the past. Our innovative system transforms organic waste into clean, reliable electricity while capturing carbon dioxide at scale.

Founded by space tech veterans who pivoted from building technology to explore new planets to protecting our own, Arbor leverages cutting-edge aerospace technology to tackle climate change. Our mission is to bring gigawatts of clean, dependable baseload power online while removing gigatons of legacy carbon emissions. Earth is the most important spaceship we’ll ever have, and we’re dedicated to restoring its balance.

Drawing on our team’s deep aerospace expertise, we’ve created a power system that meets today’s demands while repairing yesterday’s damage. Arbor’s engine, fueled by organic waste, improves on Bioenergy with Carbon Capture and Storage (BECCS) using advancements in oxy-combustion, supercritical turbomachinery, and additive manufacturing. The system turns waste—like overgrown brush, crop residues, and food waste—into clean power, reducing wildfire risks and landfill emissions. The captured CO2 is permanently stored deep underground, where it mineralizes into rock, ensuring it never returns to the atmosphere.

At Arbor, we envision a future where human progress and environmental stewardship work in harmony to power our world and bring the planet into balance. We’re proudly backed by climate-focused investors including Gigascale Capital, Voyager Ventures, Lowercarbon Capital, and Cantos Ventures.
