Technical Business Development Representative

Note: This role requires real technical ability beyond familiarity. If you haven't experimented with AI beyond chat, e.g. built automations, worked with webhooks or written scripts, this is not the right fit.

About Coolset

Coolset is the ESG & supply chain platform for compliance-first teams. We help companies like Karl Lagerfeld and Australian Gold measure, manage and improve their sustainability disclosures, simplifying complex regulations to enable real impact.

Founded in 2022 and backed by a remarkable group of early-stage investors, we're a fast-growing company of 20 ambitious engineers, researchers and commercial talent based in Amsterdam.

What you will do

As a technical Business Development Representative (what we call a GTM Engineer), this role is 50% running sales and 50% building the systems behind it. You'll own end-to-end sales processes from first touch to close while also building the automations, infrastructure, and execution that power our go-to-market engine. You'll report directly to our CEO and sit at the intersection of selling and technical implementation, where running real deals informs the systems you build to help a small team punch far above its weight.

If you find yourself doing the same thing twice, you'll see it as a signal: challenge the assumption, build a system, and free yourself up for the work that builds on your brainpower and creativity. We also deeply believe that action creates information. You'll ship fast, learn from what happens, and iterate.

You will cover:

• 50% Sales execution: From identifying prospects to sealing the deal. You will own the full cycle from first touch to go-live, helping our future customers navigate their priorities, aligning them with Coolset's solutions, and land on a commercial proposition that makes them successful

• 20% go to market automation, systems & infrastructure: Design and maintain the automations that connect our commercial stack end-to-end. Build workflows in n8n, connect APIs, set up webhooks, and eliminate manual work wherever it doesn't add value. Own and evolve our core tooling and keep data clean, integrations healthy, and reporting reliable

• 20% Technical GTM engineering: Use tools like Claude Code to build internal tools, scripts, and prototypes that accelerate our sales & marketing efforts. You're comfortable building prototypes and technical solutions across the stack

• 10% Experimentation: Run experiments across channels, messaging, and tactics. Move quickly, measure what matters, and double down on what works. Taste and judgment matter here; not everything that can be measured should be, and not everything worth doing shows up in a dashboard immediately

Tools we use

• HubSpot for CRM & email marketing
• Apollo for company and contact data
• Webflow for our website and landing pages
• n8n for workflow automations
• Claude Code for building internal tools and accelerating work
• Notion for documentation and planning
• PostHog for product analytics
• + Anything else you need

Career

You'll work directly with our CEO to build on the foundations of our go-to-market engine with real ownership and room to shape the function as we grow.

As Coolset scales, your role will naturally expand into whatever best matches your ambitions.
