Director of Operations

At Arculen, everything we do is focused on one thing: helping the nuclear industry build its workforce of the future. From next-generation energy projects to medical isotope production, nuclear is at the center of solving some of the world’s most urgent challenges. And behind every breakthrough are the people who make it possible.

We’re a startup dedicated exclusively to nuclear talent—and we’re scaling fast. To keep pace, we’re looking for a fractional Director of Operations to help us build the backbone of our business.

This is your chance to:

• Shape the operations of a founder-led startup with global ambitions.

• Play a key role in an industry that’s powering the clean energy transition and critical innovation.

• Work side by side with decision-makers, not layers of hierarchy.

• Enjoy true flexibility—around 10 hours/week, with just one in-office day each month.
‍

Who we’re looking for

This role is ideal for someone who:

• Has 5+ years in operations, business management, or professional services (consulting, search, or similar fast-paced environments).

• Knows how to connect the dots across finance, HR, legal, and systems—you see patterns and bring order without needing to do every detail yourself.

• Has experience creating or managing compensation, incentives, or promotion frameworks.

• Thrives in entrepreneurial or high-growth environments—you’re comfortable when things are fast, evolving, and sometimes messy.

• Is highly organized and structured, but also collaborative and flexible—a true partner to founders.

• Wants to make a significant contribution in a fractional or part-time capacity—bringing capability and judgment without the a full-time commitment.
‍

What you’ll do

• Keep our finances on track (payables, receivables, payroll, vendor relationships).

• Partner with our HR lead on people operations (contracts, onboarding, incentives, career paths).

• Build and improve systems and processes that help us scale.

• Oversee contracts, compliance, and IT, ensuring we’re set up for growth.

• Codify our culture and employee experience, creating a strong and connected team.

• Drive strategic projects that bring finance, HR, and operations together.

‍

What we think you’ll love

• The impact: you’ll directly influence how a startup scales.

• The mission: you’ll be part of a rapidly growing and purpose driven industry.

• The variety: every week brings something different—from refining incentives to shaping processes.

• The flexibility: contribute at a high level without the grind of a full-time role.
