If you’re passionate about using interesting technology for good and want to be part of a founding team shaping the future of climate tech, this is an exciting opportunity. At Maiven, you’ll have a chance to build impactful products with a talented and diverse team that values creativity, ownership, and growth. Our co-founders bring significant experience in tech and climate, and they prioritise cultivating an empowering, inclusive, and value-driven people-first culture from day one.

The Opportunity:

This is an exciting role for an ML/ Data Engineer with a passion for climate tech. As a founding engineer at Maiven, you will have the unique opportunity to shape our product, influence company culture, and work alongside a team that deeply cares about helping people develop and succeed.

This is a rare opportunity for an ML engineer with a desire to learn and grow while creating meaningful change, work with cutting-edge technology, and make a direct impact on customers, society and the environment.

What You'll Do:

• Lead Development: Create scalable ML pipelines to extract key policy data from complex policy documents. Architect and build inference pipelines at the heart of our product. This is greenfield development so you have the freedom and flexibility to choose the right technology for the product.

Who You Are:

• Self-starter: You thrive in an autonomous setting and are motivated by impact, ownership, and learning.

• Quick Learner: Eager to tackle complex challenges and bring creative solutions to the table. You’re able to learn quickly, pivot when necessary, and make decisions that balance short-term agility with long-term stability.
