Project Sales Engineer

We are looking for a technically fluent, commercially minded Project Sales Engineer to join our team. In this hybrid role, you will serve as the technical lead and primary point of contact throughout the full project lifecycle — from initial prospecting and solution design through delivery and client handoff. If you thrive at the intersection of engineering and business development, and you take pride in owning outcomes end-to-end, we want to hear from you.

What you'll do

Technical sales & scoping

Drive new business through prospecting, site assessments, and solution design. Develop detailed proposals, Bills of Materials, labor estimates, and project quotes that accurately reflect scope and technical requirements.

Project lifecycle management

Act as project quarterback from kickoff through delivery. Oversee engineering design, resource allocation, milestone tracking, and budget management to ensure on-time, on-budget execution.

Client relationship management

Serve as the primary client contact throughout the engagement. Set clear expectations, communicate proactively, and ensure deliverables consistently meet or exceed client requirements.

Technical solution design

Apply hands-on expertise in control systems, software integration, or energy technology to design solutions tailored to each client's operational environment and goals.

What we're looking for

Bachelor's degree in Electrical, Mechanical, or Automation Engineering — or equivalent professional experience

2–6 years of experience in technical sales, pre-sales engineering, or project management, ideally within cleantech or energy.

Demonstrated ability to manage complex, multi-stakeholder projects from scoping through delivery

Strong communication and client-facing skills; comfortable presenting technical concepts to non-technical audiences

PMP or CAPM certification is advantageous, but not required

You must be based in the Denver Metro Area or be willing to relocate. 

You might be required to travel up to 50% of the time.

You will be required to represent the company at public facing events (tradeshows, etc.)

Who you are

We are looking for a person who is self-driven and results-oriented, bringing strong opinions and the confidence to advocate for them. This person thrives working with customers and colleagues alike, naturally personable and able to build enthusiasm around solutions and ideas. We expect you to move with urgency, handle competing priorities without friction, and adapt readily when priorities shift. Rather than following a rigid playbook, we expect you to be most effective when given autonomy to find the best path forward. The ideal candidate is comfortable with ambiguity, navigates conflict constructively, and pushes projects ahead even when the picture isn't fully clear.

What we offer

Great work environment without a lot of freedom for action and the opportunity to be part of a revolution in energy storage. We are a startup with ambitions to become a unicorn in 3 years. All employees are shareholders and we expect all of us to create some wealth for ourselves while enjoying the journey.
