Job Description

About Us

We're a mission-driven cleantech company at a pivotal moment in our growth. With $2M in annual sales and a team of 17, we're scaling rapidly -- with goals to double or triple revenue in the next 18-24 months. Our work creates real environmental impact, and our team thrives on innovation, collaboration, and purpose.

The Opportunity

We're looking for a highly organized, proactive and tech-savvy Admin & Finance Coordinator with potential to grow into leading the Admin/Finance function within 12-18 months. The Admin & Finance Coordinator will play a critical role in supporting and executing key operational responsibilities across administration, HR, and finance -- helping the company scale smoothly while taking day-to-day back-office functions off the CFO's plate. The Admin & Finance Coordinator will take initiative to learn existing tools and platforms and propose smarter ways to work more efficiently. If you are someone who thrives on taking initiative and enjoys wearing multiple hats, this might be the position for you. Over time, you'll have the opportunity to help shape how this department evolves -- potentially stepping into a leadership role as the company grows.

This is a rare opportunity to build, learn, and lead -- in a company where your work will directly shape our future.

Leading internal budgeting and reporting processes

Supporting fundraising initiatives, treasury management, risk oversight, and board reporting

Analyzing and assessing organizational needs for hiring future team members to support your evolving responsibilities (finance or admin)

What We're Looking For

A minimum of 3 years of experience in finance, operations, HR, or business administration -- with an eagerness for continuous learning.

Previous experience in a startup or scaling environment would be a huge asset

A builder's mindset: organized, hands-on, resourceful, and eager to improve processes

Detail-oriented and self-driven, with a strong sense of accountability

Tech-fluent: comfortable with cloud platforms and quick to learn new tools (e.g., QuickBooks, Microsoft 365, payroll/HRIS systems, ERP)

Strong communicator and collaborator, able to work cross-functionally with internal and external partners

A desire to grow into a leadership role and take on significant responsibility

Bonus: Experience in cleantech, hardware companies, or B2B environments
