Data Scientist

Permanent employee, Full-time · Berlin

About The Role
As an Data Scientist you will work closely with our technical founder to build our core ML capabilities. This includes data processing, simulation, model development, validation, agent training, and ML operations. To build impactful solutions, you will immerse yourself deeply into our industrial customers' reality to apply your experience and intuition of ML technologies to the task and work closely with our platform engineers to bring results to production in short iteration cycles.  If you like to push the boundaries of what is possible with ML and technology, Juna is the right place for you.

Core Responsibilities
  • Data Processing: Together with our platform team develop tooling to automate the processing and analysis of massive amounts of real-time industrial process data such as high frequency sensor data.
  • Model Development: Research, train and evaluate AI models to optimize industrial processes, using state of the art re-enforcement learning, numerical optimization, and control theory.
  • Algorithm Development: Merge physical insights and customer knowledge with AI to improve model performance and safety and tailor our models to customer needs.
  • Performance Validation: Validate AI efficacy across diverse datasets, ensuring robust performance.
  • Quality & Safety Monitoring: Develop quantitative methods for automated monitoring of models in production.
  • Model Deployment: Work closely with our platform engineers to integrate ML into the production environment.
About You
Tech Excellence
  • ML Expertise: Strong background in Machine Learning, Reinforcement Learning, or Applied Mathematics – ideally with experience in control, simulation, or time-series modeling
  • Production-Ready Skills: Proficient in Python and modern ML frameworks (e.g., PyTorch, JAX, TensorFlow)
  • Operational Understanding: Solid grasp of MLOps principles and experience taking models from research into production
  • Data Fluency: Comfortable working with large, messy, real-world datasets (sensor data, time-series, etc.) 
  • Bonus: Experience with control systems (PID, MPC Control), Reinforcement Learning and real-time AI Agents
Personal Qualities
  • Analytical Thinking: Analytical thinker who thrives on solving hard, technical problems with elegance and precision
  • Builder Mentality: Pragmatic builder with a bias for shipping and keeping solutions simple
  • Ownership & Initiative: Collaborative and self-directed—able to drive projects independently while working cross-functionally with engineering and product teams
What we offer
  • Impactful Work: An opportunity to shape the future of manufacturing by contributing to groundbreaking AI technologies that decarbonize heavy industries.
  • Ownership: Equity participation, allowing you to share in our success as we grow.
  • Collaborative Environment: Work closely with experienced tech founders and a team of leading researchers, engineers, and entrepreneurs.
  • Professional Growth: Contribute your knowledge to drive our vision forward, with ample opportunities for learning and development.
  • Inclusive Culture: A commitment to equal rights, mutual respect, and the promotion of diversity in our workplace.
Life At Juna
We operate on the factory floor, not in slide decks. At Juna, you’ll solve high-stakes problems in the real world – chemical plants, paper lines, steel mills  – and cut emissions of the biggest polluting industries in the world. We move fast, work face-to-face, and care about outcomes and solving customer problems. Juna is the place where you’ll experience the most impactful and productive time of your career.
About us
Juna AI is revolutionizing heavy industries by leveraging AI-enabled autonomous agents to decarbonize and optimize industrial processes. Our mission is to transform complex manufacturing facilities into intelligent, self-learning systems that operate autonomously, delivering significant improvements in plant performance and sustainability. Our AI-based control system learns from sensor data to control complex processes in real time across industries like chemical, steel, paper, cement, and textile. 

Juna’s founders, Matthias Auf Der Mauer and Christian Hardenberg, are serial entrepreneurs with a proven track record of founding successful startups, developing advanced AI and IoT applications, and scaling technology solutions globally for over 100 million users. They have led engineering teams of up to 2,500 engineers, launched more than 50 internet companies, and introduced transformative AI technologies to the manufacturing sector. Backed by extraordinary investors like Kleiner Perkins and Norrsken VC – the same backers behind companies like Google, Amazon, and Twitter – we are poised to make a significant impact on the future of industrial automation.
