About Tree-Nation

Tree-Nation is the largest reforestation platform that allows citizens and companies to plant trees all around the world and offset their CO2 emissions.

We use technology to make tree planting easy. Tree-Nation invented the virtual tree, the online forest, and many other software tools to provide a unique technological solution aimed at shortening the distance between remote projects and their sponsors — between people and companies that want to plant trees and expert planters around the world.

Since our beginning in 2006, over 700,000 users and more than 20,000 companies have planted over 40 million trees using our platform, and we have successfully onboarded over 50 reforestation projects all around the world.


Let's make a difference together.

Work environment

Our team spans a wide range of nationalities, cultures, and backgrounds. On paper, we’re very different. In practice, we operate with the same mindset: we solve problems, move fast, and adapt as needed.

We’re constantly in search of individuals who embody the “Swiss knife” mentality — versatile and adaptable professionals who can seamlessly transition between various roles and tackle a wide range of challenges. Much like this iconic tool, we value team members who are creative problem solvers, resourceful, and possess a diverse skill set. (And no, this does not mean that being from Switzerland is a requirement 😀).

About this position

Your role as Director of Sales Engineering is a cornerstone of Tree-Nation’s next stage of growth. You’ll be the main sales leader in the company — owning revenue generation, leading outbound strategy, managing key client relationships, and building the infrastructure that enables scalable, tech-enabled growth.

But this isn’t a classic sales leadership role.

To succeed, you’ll need more than just commercial instincts — you’ll need engineering literacy and an AI-native mindset. Our product is deeply technical (API-driven, SaaS-integrated, automation-ready), and our future depends on building a hybrid sales engine where AI agents + humans work together to drive impact.

This is a rare opportunity for someone who wants to lead sales and shape the company’s technical growth culture from the inside.

Job requirements

What you’ll do

  • Own technical revenue growth: Combine product understanding, outreach, and integration capabilities to unlock scalable channels.

  • Lead and scale our outbound sales engine across Europe, the US, and Asia — targeting mid-market and enterprise clients.

  • Build and manage a hybrid sales model: humans + AI agents working together across prospecting, qualification, and closing.

  • Design and maintain the sales systems behind outreach, onboarding, and success: CRM (HubSpot), messaging automations, metrics, and reporting.

  • Master and promote our API: Help clients connect through custom or no-code integrations. Understand blockers, guide implementations, and propose product improvements.

  • Prototype and build integration workflows using tools like n8n, Zapier, or custom scripts.

  • Drive client integration success: Solve our biggest bottleneck by ensuring smooth technical onboarding and frictionless adoption.

  • Translate product into story: Work with product and engineering to turn features into simple, powerful narratives for clients.

  • Lead strategic partnerships with SaaS platforms, ecommerce tools, and ecosystem partners to embed planting into user journeys.

  • Coach and scale the sales org: Build systems and capabilities to support long-term scale.

  • Bridge sales, product, and tech: Align internal teams around customer problems and technical solutions.

  • Represent Tree-Nation in key deals and negotiations and report directly to the CEO as the owner of revenue.

What you’ll bring

  • Proven B2B SaaS sales leadership (zero to scale).

  • Outbound sales mastery — systems, automation, funnel optimization.

  • Fluent English communication, both written and spoken.

  • CRM mastery — HubSpot or equivalent: automation, pipeline architecture, custom workflows, and reporting.

  • Technical literacy — you understand APIs, SaaS integrations, and automation platforms like n8n or Zapier. You don’t need to code daily, but you speak the language and can lead technical conversations.

  • AI-native mindset — you've built or actively used AI agents in sales workflows and see AI as a core part of the sales engine today, not tomorrow.

Strongly Preferred

  • Past experience in a technical role — software engineer, sales engineer, solutions architect, or technical consultant.

  • Proven ability to bridge sales, product, and engineering — you’re a translator between commercial needs and technical solutions.

  • Track record of solving integration challenges with clients using APIs, automation platforms, or product modifications.

Nice-to-Haves

  • Fluency in additional languages (Spanish, French, etc.).

  • Academic background in a STEM field.

  • Personal passion for climate, sustainability, or social impact.

The perfect candidate can be described as follows

  • Sales-first, but technically fluent — you can close, but you can also architect.

  • Visionary with a bias for execution — fast-moving and pragmatic.

  • A strategic thinker with a strong instinct for building scalable systems.

  • Comfortable with ambiguity — ready to shape something new rather than inherit it.

  • A clear, inspiring communicator — across stakeholders, cultures, and disciplines.

  • Deeply accountable, organized, and focused under pressure.

  • Passionate about climate action and the real-world impact of your work.

What we offer

  • Join a mission-driven company tackling one of the greatest challenges of our time — and building real solutions at scale.

  • Competitive base salary with performance-linked bonus.

  • Permanent contract with a long-term vision.

  • Work in our unique nature-immersed offices, designed as a living lab for sustainability and ecological innovation.

  • Memorable team-building activities and an international, purpose-aligned team culture.
