Job Description

Role Description

The Lead AI Research Scientist designs and analyzes machine learning experiments and develops and validates new AI Techniques, and collaborates with cross-functional teams to apply research to real use cases. This role supports model optimization, creates reusable research assets, and contributes to advancing the Company’s AI initiative.

  • Design, execute, and analyze machine learning experiments, establishing strong baselines and selecting appropriate evaluation metrics.
  • Stay up to date with the latest AI research; identify, adapt, and validate novel techniques for company-specific use cases.
  • Define rigorous evaluation protocols, including offline metrics, user studies, and adversarial (red team) testing to ensure statistical soundness.
  • Specify data and annotation requirements; develop annotation guidelines and oversee quality control processes.
  • Collaborate closely with domain experts, product managers, and engineering teams to refine problem statements and operational constraints.
  • Develop reusable research assets such as datasets, modular code components, evaluation suites, and comprehensive documentation.
  • Work alongside ML Engineers to optimize training and inference pipelines, ensuring seamless integration into production systems.
  • Contribute to academic publications and represent the company in research communities, as needed.

Qualifications

  • Ph.D. in Computer Science, Artificial Intelligence, Machine Learning, or a related field is strongly preferred.
  • Candidates with a master’s degree and exceptional research or industry experience will also be considered.
  • 5–7 years of experience in AI/ML research roles, ideally in applied or product-focused environments.
  • Demonstrated success in delivering research-driven solutions that have been deployed in production.
  • Experience collaborating in cross-functional teams across research, engineering, and product.
  • Publications in top-tier AI/ML conferences (e.g., NeurIPS, ICML, ACL, CVPR) are a plus.
  • Strong foundational knowledge in machine learning and deep learning algorithms.
  • Hands-on experience with PEFT/LoRA, adapters, fine-tuning techniques, and RLHF/RLAIF (e.g., PPO, DPO, GRPO).
  • Ability to read, implement, and adapt state-of-the-art research papers to real-world use cases.
  • Proficiency in hypothesis-driven experimentation, ablation studies, and statistically sound evaluations.
  • Advanced programming skills in Python (preferred), C++, or Java.
  • Experience with deep learning frameworks such as PyTorch, Hugging Face, NumPy, etc.
  • Strong mathematical foundations in probability, linear algebra, and calculus.
  • Domain expertise in one or more areas: natural language processing (NLP), symbolic reasoning, speech processing, etc.
  • Ability to translate research insights into roadmaps, technical specifications, and product improvements.

Requirements

  • 5 to 7 Years of relevant work experience.

Benefits

  • Comprehensive benefits package designed to support the physical, emotional, and financial health of you and your family, including healthcare, time off, retirement, and well-being programs.
  • Professional development opportunities, including earning a professional certification relevant to your field and tuition reimbursement.
  • Quarterly and annual incentive programs for all employees who exceed expectations.
