Principal AI Engineer

There are NO limits to your career: come shape the future and be part of a truly unique global culture at OutSystems!

About This Role

We are seeking a Research Scientist specializing in Large Language Models to drive innovation and develop cutting-edge AI solutions, particularly in code generation and understanding. You will engage in applied research and practical applications, collaborating with cross-functional teams to integrate advanced LLM capabilities into our products.

Key Responsibilities

• Model Training: Design and implement scalable training pipelines for LLMs, focusing on code generation and comprehension tasks.​

• Reinforcement Learning for LLMs: Utilize Reinforcement Learning (RL) methodologies to enhance LLMs, specifically by training/fine-tuning for improved reasoning and alignment, and by adapting code generation models to perform better on new or domain-specific programming languages.

• Model Evaluation: Develop robust evaluation frameworks to assess model performance using both automated metrics and human feedback.​

• Research and Development: Advance LLM capabilities in code generation and comprehension by exploring and implementing state-of-the-art techniques, ensuring models generate accurate, efficient, and contextually relevant code.​

• Collaboration: Work with engineering and product teams to translate research into real-world applications.​

• Knowledge Sharing: Publish findings in reputable conferences and contribute to the AI research community.​

What You Need To Succeed

• LLM Development: Proven experience in training, fine-tuning, and deploying large language models, particularly for code generation and comprehension tasks.​

• Reinforcement Learning Application: Demonstrated experience applying Reinforcement Learning techniques (e.g., RLHF, PPO, RLAIF) to train or fine-tune large language models, specifically for improving reasoning, alignment, or adapting models to new domains/tasks like novel programming languages.

• Machine Learning Expertise: Strong foundation in machine learning principles, with hands-on experience in deep learning frameworks such as PyTorch, TensorFlow, and JAX.​

• Programming Proficiency: Advanced coding skills in Python, with the ability to develop end-to-end prototypes, including data engineering, data analysis, and algorithm implementation.​

• Data Processing: Experience with data processing platforms like Apache Spark or Ray for efficient handling of large datasets.​

• Problem-Solving and Innovation: Creative, ambitious, and curious mindset with a resourceful and innovative approach to tackling complex challenges.​

Qualifications

• Educational Background: Ph.D. or M.Sc. in Computer Science, Artificial Intelligence, Machine Learning, or related technical fields.​

• Professional Experience: A combined total of 5+ years of experience in applied machine learning roles, encompassing both academic research (such as Ph.D. studies and postdoctoral research) and industry positions. Within this, at least 2 years of experience focused on large language models (LLMs) is preferred.​

• Specialized Knowledge: Deep expertise in deep learning architectures, neural networks, sequence models, and natural language processing, and reinforcement learning techniques applied to NLP/LLMs.

• Technical Proficiency: Extensive experience with machine learning and deep learning frameworks such as TensorFlow, PyTorch, and JAX; familiarity with data processing tools like Apache Spark and Ray; and proficiency with model optimization libraries like DeepSpeed. Experience implementing and experimenting with RL algorithms for LLM training is highly desirable.

• Production Experience (Preferred): Experience deploying large language models in production environments, ensuring scalability and reliability, is a plus.​

• LLMs for Code (Preferred): Experience with machine learning and LLMs applied to code generation and comprehension is advantageous.​

• Strong Publication Record (Preferred): A publication record at top ML and/or NLP conferences (NeurIPS, ICML, ICLR, ACL, EMNLP, …) is a big plus.
