Data Science Researcher

About Calaxis by Credartha

Calaxis by Credartha is on a mission to unchain AI development. We believe the $15 trillion promise of AI is being held hostage by a broken, fragmented, and prohibitively expensive development process. Our integrated pipeline is engineered to master data and empower organizations to own their future by building trustworthy, domain-specific AI. We are eliminating the bottlenecks of slow, biased, and unscalable manual annotation by pioneering a new method. Our core innovation, the "Council of Judges," automates expert data validation, replacing human armies with a cascade of specialized AI models to deliver systematic, scalable quality assurance.

The Role

We are looking for a pioneering Data Science Researcher to be the engine of our innovation and the architect of our technological advantage. You will be responsible for advancing the core intellectual property that underpins our entire platform. This role goes beyond applying existing models; you will be conducting foundational research to build, refine, and scale our proprietary methodologies, including our "Council of Judges" and our "Deeptech Self-Improving Flywheel".

Your work will directly contribute to keeping Calaxis at the forefront of the AI evolution, ensuring our methods remain more efficient and powerful than the capital-intensive approaches that dominate the market. If you are driven to solve the most challenging problems in AI data generation, validation, and model improvement, and want to see your research have a direct commercial impact, this role is for you.

What You'll Do:

• Lead foundational research and development of our "Council of Judges" AI, including advancing our proprietary "Two-Tiered" training paradigm.
• Design and implement novel algorithms and experiments to enhance the "Deeptech Self-Improving Flywheel," ensuring our entire system becomes more intelligent and efficient over time.
• Spearhead the research, testing, and integration of advanced Reinforcement Learning (RL) techniques to enhance our data generation and validation capabilities.
• Drive the continued development of our custom architectures, including our Multimodal LLM (VLM) for interpreting visual data and our Retrieval-Augmented Generation (RAG) pipeline.
• Innovate on our Central Dataset Generator to improve the quality and complexity of our automatically generated instruction-following datasets.
• Develop new methods for automated data validation and quality assurance, pushing the boundaries of what is possible in building trustworthy AI.
• Publish your findings in top-tier AI conferences and journals, establishing Calaxis as a thought leader in the industry.
• Collaborate closely with the engineering team to translate cutting-edge research into robust, scalable components of our production platform.

Who You Are:

• You possess a Ph.D. , Master's or Bachelor's degree in Computer Science, Artificial Intelligence, Machine Learning, or a related field, with a strong publication record.
• You have proven experience in conducting original research in Natural Language Processing (NLP), and Machine Learning, particularly with Large Language Models (LLMs).
• You have deep expertise in areas such as Reinforcement Learning (especially RLHF), model fine-tuning, retrieval-augmented generation (RAG), and data generation techniques.
• Experience with multimodal models (V)LM is a significant advantage.
• You are a master of scientific programming with expert-level skills in Python and deep learning frameworks like PyTorch or TensorFlow.
• You have a pioneering mindset and are driven by the challenge of creating new methods, not just applying existing ones.
• You are capable of working independently to define research problems and see them through to production-ready solutions.
