AI Engineer

Full time

At ImpactNexus, we develop software that makes it easy for companies and their investors to take action on sustainability.

In 2015, the world's leaders committed to a sweeping set of targets to improve health and education, reduce inequality, and spur economic growth – all while tackling climate change and working to preserve our oceans and forests by 2030. It's clear that the world is nowhere near on track to meet these 17 Sustainable Development Goals, and we need a systemic change and we need it fast. This means sustainable alternatives need to scale fast and established companies need to change their strategy. It’s our mission to be a catalyst for the transition toward a sustainable economy by making it easy for millions of companies to become more sustainable.

With a still quite small but growing tech team, we’ve developed impact management software for companies and their investors to assess their impact, help them to track and report their progress and provide first improvement suggestions. At its core, we develop a cause and effect knowledge base that links business activities to sustainability risks and opportunities to provide tailored improvement recommendations.

Our database is based on three types of data: User data, data from external data providers (e.g. on CO₂ emissions, life-cycle assessments, etc.) and public documents such as research articles, trade magazines, news or blogs. Based on this database, we can assess the sustainability impacts of companies and make relevant suggestions for improvement with minimal data input. Our goal is to be able to show initial evaluations and relevant improvement potentials for a company in less than 10 minutes and to achieve this, we need you to join our team.

We value mutual trust, transparency, and cooperation across teams, domains, and workstreams. We embrace vulnerability and we’re open with what we don’t know and what we don’t understand. We're looking for many perspectives to form a holistic view and create a system we can be proud of.

We’re currently working from a WeWork office or remotely. We have occasional evening events (mostly cooking stuff together or going to a beer garden) and offer flexibility for you to choose to work from home or to come to the office. Given half of our team are parents of young children, we try to create a family-friendly work environment that gives you the flexibility you need.


ImpactNexus is looking for an innovative and passionate Machine Learning Engineer to join our engineering team. You’ll design, build, and manage our impact knowledge base to enable data-driven decision-making at scale by providing tailored impact information for companies.

How You’ll Make An Impact

> Lead the development, deployment, and maintenance of ML products integrated into our software, working in close collaboration with our Product and Engineering teams.

> Spearhead architectural, design, and infrastructure decisions, considering cost/benefit trade-offs, to drive optimal solutions.

> Stay abreast with cutting-edge developments in pertinent ML areas and pragmatically incorporate them into our software to enhance capability.

> Actively involve in hands-on implementation, especially in the first year, focusing on designing and setting up scalable solutions in our pipeline.

> Engage in various tasks beyond ML, demonstrating practicality and a commitment to delivering high-quality results to drive the success of ImpactNexus.


We’re looking for you if:

> Proven and at least 2 years of experience as a Machine Learning Engineer or similar role.

> Comprehensive understanding of machine learning models, architectures, and best practices.

> Proficiency in programming languages such as Python with a strong emphasis on writing clean, maintainable code.

> Excellent communication and multitasking skills with a focus on practical delivery.

> You are located in Germany, ideally Berlin, with a valid work visa.


> Permanent position with flexible working hours (30-40 h per week depending on your preferences)

> 26 days of vacation for a full-time position

> Shape the future: Build something that matters and learn about sustainability's impact on business

> Flexibility and Freedom: We do not believe in micro-managing. Your responsibilities and tasks are your own and we will support you to achieve these. We won’t breathe down your neck! Take your time to shape your ideas and thoughts and work the way you like.

> Ownership and Empowerment: We empower you to own your ideas from conception to delivery and we support each other’s professional and personal development, e.g. through regular 1:1 meetings.

> Work-Life-Balance: We encourage flexibility in work hours and design policies to allow you to spend maximum time with your family or personal development (e.g. sabbaticals, thesis projects). This is being lived by the founding team.

If you are interested in joining us, send us examples of your work (e.g., GitHub repo), your letter of motivation, and your CV. The next steps will be an interview with a member of our engineering team, a work assignment (2 hours max) and a meeting with the founder team.
