Arbor Energy

Rocket engineering for power generation.

Arbor is a next-generation turbine company using rocket engineering to deliver clean firm power. Rocket engines generate enormous power out of very small volumes. Arbor applies that approach to power generation, using supercritical CO₂ to deliver the same power from a turbine roughly one-tenth the size of a conventional one. Turbine engineering supplies the materials and cooling a power system needs to run continuously for decades. Arbor’s power system, HALCYON, uses oxy-combustion—burning fuel in pure oxygen—to eliminate NOx, SOx, and particulate emissions. This process enables CO₂ to be captured directly from the fuel and stored permanently underground. It also produces water, so a plant can operate without drawing on local water supplies. Each HALCYON unit delivers 25 MW, and units can run independently or get combined into plants of 100 MW and more as demand grows. Components are additively manufactured on standard 3D printers, offering a path outside the legacy supply chains th

About Us

At Arbor Energy & Resources Corporation ("Arbor Energy"), we’re creating technology to power our lives while protecting the planet that sustains them.  Our advanced power systems deliver clean, reliable baseload electricity with zero operating emissions—modular, fuel-flexible, and engineered for the realities of today’s energy demand. At the core is a supercritical CO₂ turbine with integrated carbon capture, designed to bring carbon-neutral power online quickly at meaningful scale. 

Our team includes aerospace engineers, combustion experts, and systems thinkers with a shared goal: to build technology worthy of the world we want to live in. While many of us began our journeys looking to the stars, we’re applying that expertise here at home to deliver dependable, emission-free baseload power and a future of lasting abundance.  

If you share our values and are drawn to rigorous work with lasting impact, we’d love to learn more about you. Come build what the future will run on.

Steward our planet: We build for tomorrow, ensuring every bolt we tighten and every hand we lend leaves our environment stronger than we found it.

Lead with Love: We champion the success of our people, partners, and planet, nurturing excellence through camaraderie and rigor.

Explore the Uncharted: We embrace the unknown with curiosity, using courage and discipline to transform uncertainty into opportunity.

Role Overview

We're looking for a Technical Project Lead to drive the engineering and execution of Arbor's first-of-a-kind supercritical CO₂ power plant, from front-end engineering through construction, commissioning, and first power. Arbor acts as its own integrator, so this is an engineer's role first: someone with deep roots in process or power plant engineering who understands every dependency on a project and knows when to deploy each part of the team. You'll start hands-on authoring plant-level process design during FEED, then shift toward integration and field leadership, on site from module arrival through first fire before handing the plant to its operations team. This is a long-term leadership track: lead that plant through first fire, carry that experience into the first commercial project, then grow into a broader leadership role as the fleet expands. You'll work closely with the project manager and with turbomachinery, combustion, controls, electrical, and test engineers to deliver the plant that proves carbon-neutral baseload power at scale.

Responsibilities

  • Own the integrated technical execution plan: map dependencies across disciplines, permitting, and procurement, and sequence work by what each decision actually needs.
  • Author or direct plant-level process design (PFDs, heat and material balances, P&IDs, relief and utility design), integrating Arbor's core technology with balance-of-plant systems.
  • Identify critical-path equipment early and lead long-lead procurement: specifications, bid evaluations, vendor design reviews, and factory acceptance tests.
  • Scope, select, and manage engineering firms, fabricators, and construction contractors; review their work in depth and own the interfaces between packages.
  • Lead process safety (HAZID, HAZOP/LOPA, PSSR) and build constructability, modularization, and commissioning sequence into the design from the start.
  • Be the on-site technical authority from module integration through first fire and shakedown, resolving field issues with design authority alongside the construction manager and plant operations team.
  • Partner with project management and supply chain on estimates, schedule, and contracting strategy, and carry lessons into standardized designs for the units that follow.

Requirements

  • Bachelor's degree in Chemical, Mechanical, or related Engineering field.
  • 8+ years of experience in process or power plant engineering, including carrying at least one pilot, demonstration, or commercial facility from front-end design through commissioning and startup with significant time on site.
  • Strong process engineering fundamentals—heat and material balances, P&IDs, equipment specification, relief design, HAZOP/LOPA—and working knowledge of ASME B31.3, BPVC Section VIII, and API 520/521.
  • Enough breadth across mechanical, electrical, controls, and civil disciplines to spot cross-discipline dependencies and critically review others' work.
  • Owner's-side experience directing engineering firms, vendors, and contractors, with a well-formed point of view on how contracting strategy and sequencing drive project cost and schedule.
  • Based anywhere in the U.S. near a major airport; no relocation required. Expect about 10 days a month of travel during engineering (headquarters and our engineering partner's office) and up to three weeks in four on site from module arrival through first fire, roughly eight months per plant.
  • Strong ownership mentality and sound judgment with incomplete information in a small, dynamic team.

Preferred Qualifications

  • First-of-a-kind or new-technology scale-up experience where you carried both process design and project execution.
  • Experience with gas turbine or combined-cycle plants, high-pressure rotating equipment, air separation, CO₂ compression, or supercritical CO₂ systems.
  • Experience with owner-integrated, EPCM, multi-package, or modular execution as alternatives to lump-sum EPC.
  • Operations or commissioning roots in a PSM-covered process facility or power plant.
  • Process simulation (Aspen HYSYS, Aspen Plus) and scripting (Python, MATLAB) skills.

Benefits & Compensation

  • Pre-IPO stock options
  • Medical, dental, and vision insurance (Arbor covers 90% for employees)
  • Basic life insurance fully covered
  • Health savings account (HSA) with matching
  • Flexible savings account (FSA)
  • Unlimited PTO  
  • 12+ company holidays, including Earth Day!  
  • 401(k)
  • Commuter benefits
  • Annual learning and development stipend
  • And more!

Base Pay: $175,000 - $225,000 USD/year. The salary is subject to the applicant's skills, qualifications, experience, and geographic location.
