Business Operations Associate

Stemwave

• Seaport, Boston
• Full‑time, In‑person

Hi—I'm Tom Kostopoulos, Founder and CEO of Stemwave. I'm hiring someone to work directly alongside me, and I want to be honest about what this is. It's not a typical job. I'm looking for a person I can bring right into the middle of how I run this company—someone who sits next to me on the real work, watches how decisions get made, and over time starts making more and more of them on their own.

I've done a lot of this myself, and I'm still doing most of it. This role exists because I want someone alongside me learning it all—so that a year or two from now, they're taking real weight off my plate and I trust them to act the way I would.

If you're exceptional, hungry, and want to learn how to actually run a company from the inside, keep reading.

Stemwave is a medical device company. We make a shockwave therapy device used by clinics to treat patients—technology that helps people get out of pain and back to their lives.

We're 100 people, based in Seaport, Boston. We've never raised outside capital—not a single dollar. Everything we've built, we've built on our own revenue. We've grown roughly 70% a year for three straight years and made the Inc. 500 three years running.

That combination—profitable, self‑funded, and growing fast—means we operate differently than most companies our size. We move quickly, we're accountable to ourselves rather than to investors, and every hire genuinely matters.

You'll work directly with me as my Business Operations Associate. Think of it as an apprenticeship in running a company. You'll start by working side‑by‑side with me on the actual work—carrying projects, sitting in on decisions, and learning how the business and I think. Over time, you'll take more and more off my plate and begin operating independently on the things that matter.

Own projects end‑to‑end. You'll be handed real initiatives and be accountable for driving them to completion, giving me a clear weekly picture of where each stands, what's blocked, and what's next. Nothing gets dropped.

Learn to act on my behalf. Through daily proximity to how I make decisions, you'll develop the judgment to make good calls when I'm unavailable—on management questions, on tradeoffs, on "what would we do if we tried this." I'll train this with you over time, in real situations.

Run the company's operating rhythm. You'll grow into running our monthly all‑hands and leadership meetings, keeping the organization's cadence tight and making sure follow‑through happens.

Free up my time. As you earn trust, you'll take work fully off my plate—executing independently with little direction and becoming a genuine thought partner rather than someone waiting to be told what to do.

Month one:
You'll join every meeting I'm a part of and get integrated into the operations of the company. Week by week, you'll also embed with a different department—spending a full week with each—to understand how the organization actually operates and gather as much information as you can.

Month two:
You'll start taking ownership of certain projects and giving me weekly updates on them, while sitting in on leadership and all‑hands meetings.

Month three:
You'll be working day‑to‑day on those projects, pushing things downfield, speaking on my behalf, and organizing things in a way that makes sense.

• High emotional intelligence. You read people and situations well, and you navigate sensitive dynamics with maturity.
• Exceptional communication and interpersonal skills. You're outstanding both at conveying ideas clearly and at building strong working relationships across the organization.
• A relentless work ethic. You bring intensity and consistency, and you don't need to be pushed.
• High processing speed. You think and move fast, absorbing information quickly and turning it into action.
• Strong autonomous decision‑making. You're comfortable making calls on your own and standing behind them.
• A fast learning curve. You absorb quickly, take feedback well, and get sharper every week. This role is built for someone who wants to…
