About Tree-Nation

Tree-Nation is the world's largest reforestation platform, connecting citizens and companies with verified planting projects across the globe. Since 2006, over 800,000 users and 30,000 companies have planted over 45 million trees through our platform, across 40+ reforestation projects worldwide.

We combine technology and environmental impact to make reforestation simple, transparent, and scalable. Our goal is to plant 1 trillion trees by 2050 — and we are building the platform, the automation, and the systems to get there.

Why This Role Exists

Revenue at Tree-Nation comes in two main forms: companies committing to recurring planting (e.g., annual pledges), and companies integrating Tree-Nation into their systems via API, plugins, or automation tools. Some deals are commercial and relationship-driven. Others require technical integration before revenue can happen.

This role owns both. You are responsible for turning qualified leads into recurring revenue — whether through a simple pledge structure or a fully integrated API solution.

About This Position

You will manage inbound and SDR-qualified outbound opportunities and take full ownership of converting them into long-term recurring revenue (MRR). Depending on the client, this may mean structuring a recurring planting commitment with no technical work, designing and guiding a full API integration, helping a Shopify brand activate a plugin, or supporting an automation flow through Zapier or webhooks. You must be comfortable switching between commercial discussions and technical conversations — sometimes in the same call.

The Team — What We Are Made Of

Our team spans many nationalities, backgrounds, and disciplines. What we share is not a background — it's a mindset. We take ownership without being asked. We don't back down from hard problems — we enjoy them. We iterate fast, we wear multiple hats, and we go beyond what our job description says when the mission needs it.

We fear one thing above all: the routine.

We believe people do their best work when they genuinely care about what they're building. We try to keep it that way.

We are investing heavily in automation and AI to scale our impact — and we expect everyone on the team to engage with those tools as a natural part of their work.

We are based in Barcelona and work primarily from the office, because the density of collaboration matters to us.

What You'll Do

Revenue Ownership

  • Manage qualified inbound and outbound leads.

  • Identify the most appropriate activation model for each client — pledge vs integration.

  • Drive recurring revenue growth (MRR) and work within standardized pricing structures.

  • Work with Account Managers to ensure recurring commitments are maintained over time.

Integration & Technical Enablement

  • Guide API implementations (REST) and support webhooks and automation flows.

  • Assist clients with Shopify and WooCommerce plugin activation.

  • Help clients reason about system architecture and data flows.

  • Debug issues and clarify documentation when needed — the more autonomous you are technically, the better.

Systems & Process Thinking

  • Monitor integration and pledge activation success rates.

  • Reduce friction in technical onboarding and improve conversion rates where technical complexity is involved.

  • Collaborate with product and engineering teams to simplify activation.

AI-Driven Execution

  • Use AI tools to improve efficiency in qualification, communication, and troubleshooting.

  • Identify automation opportunities within your own workflow.

  • Contribute to making revenue operations more scalable.

KPIs

Primary

  • Monthly Recurring Revenue (MRR)

Secondary

  • Conversion rate when integration is required

  • Time-to-activation (pledge or integration go-live)

  • Integration success rate

What You'll Bring

Required

  • Mid-level or above experience in technical sales, growth, or solutions roles.

  • Strong understanding of APIs and integration logic — able to discuss implementation details with engineers and read technical documentation comfortably.

  • Excellent English — mandatory.

  • Comfortable owning revenue targets (MRR) and managing recurring commercial relationships.

  • Structured, KPI-driven, and solution-oriented rather than aggressive.

  • Highly efficient, proactive, and accountable in day-to-day execution.

  • Office-based in Barcelona — no remote.

Strong Advantage

  • Experience in SaaS, APIs, or platform-driven businesses.

  • Basic coding skills.

  • Spanish and/or French.

  • Ability to learn new integration environments quickly.

Mindset

  • High ownership — you take initiative, but you also know when to listen first. Tree-Nation does things differently, and the best people here understand context before trying to change it.

  • Comfortable with direct, no-frills feedback — we value honesty over diplomacy.

  • Systems thinker — you look for the root cause, not the quick fix.

  • Resilient and self-motivated — your drive comes from the mission, not from your manager's approval.

  • Genuinely aligned with the mission — this is not just a job to you.

What We Offer

Compensation & Contract

  • Competitive base salary aligned with market and experience

  • Performance-based bonus

  • Permanent contract

Benefits

  • Flexible Remuneration Card covering meals and transport

  • Gympass membership

  • Regular team-building events

Environment

  • Office-based in Barcelona — our offices are built around sustainability and designed to inspire

  • A high-impact, tech-driven environment at the intersection of sustainability and software

  • Direct exposure to product thinking and process optimization

  • A place where failure is part of the process — if nothing is failing, we're not pushing hard enough
