Overview

Founding CTO Opportunity - Climate Tech Startup - Post-Seed - Berlin - Competitive Salary + Equity

We’re partnering with a fast-moving Climate Tech startup on a mission to build solutions that address the most urgent challenge of our time, the climate crisis. Backed by respected climate-focused investors and fresh off a successful seed round, we’re now looking for a CTO to lead technology and product innovation as we move into our next phase of development.

This is a rare opportunity to join at a foundational stage and shape the technical direction, team culture, and long-term impact of a company with climate at its core.

What You’ll Do

• Own and define the technical vision, architecture, and execution roadmap across all product initiatives.
• Work closely with the CEO and founding team to align technology with business and climate impact goals.
• Build and scale the engineering team , starting with key hires and evolving into a high-performing technical org.
• Establish core engineering processes including development, testing, security, deployment, and iteration cycles.
• Lead the development of our first commercial product — from MVP to production and beyond.
• Collaborate with data scientists, hardware teams (if applicable), or domain experts to integrate cutting-edge climate technologies.
• Foster a culture of sustainability-focused innovation, technical excellence, and purpose-driven problem solving .

What You’ll Bring

• Proven experience as a senior engineering leader or technical co-founder — ideally in early-stage startups or mission-driven environments.
• Strong technical breadth in full-stack or systems development, with deep understanding of scalable architecture and infrastructure.
• Bonus if you have experience with IoT, geospatial data, energy systems, hardware integration, or climate modeling tools — though not required.
• Ability to make sound build vs. buy and architectural decisions in high-ambiguity, fast-moving environments.
• Passion for solving real-world problems through technology — ideally with a strong personal connection to climate or sustainability.
• Natural leadership instincts — able to recruit, mentor, and inspire talented engineers and interdisciplinary teams.
• Strong communicator who can collaborate across product, business, investors, and mission stakeholders.

What’s on Offer

• Founding-level role with significant ownership — both in equity and in impact .
• Competitive salary + meaningful equity package.
• Flexible, remote-friendly culture — Berlin HQ with hybrid options across EU time zones.
• A mission-driven company backed by top climate VCs and advisors with deep sector knowledge.
• The chance to work on technology that can drive measurable climate impact , not just incremental change.
• Early influence over company culture, product roadmap, and technology choices.
