Job DescriptionWe recognize that our people are our strength and the diverse talents they bring to our global workforce are directly linked to our success. We are an equal opportunity employer and place a high value on diversity and inclusion at our company.
As a Machine Learning Scientist - Natural Language Processing (NLP) - Senior Associate, you will build scalable, production-grade advanced ML solutions across natural language processing, speech recognition, recommendation systems, information retrieval, and agentic AI. You will play a key role in delivering Generative AI capabilities - designing and productionizing LLM-powered systems such as RAG (Retrieval Augmented Generation), tool/function-calling agents, and structured generation to automate complex workflows and improve customer experiences. You will collaborate with product, engineering, and control partners to translate ambiguous problems into measurable goals, deliver robust models, and operate them reliably in production. You bring strong deep learning and transformer-based modeling expertise, hands-on experience in fine-tuning and evaluation. You must have a strong passion for machine learning, strong analytical thinking, a deep desire to learn, and high motivation. You must also invest independent time in learning, researching, and experimenting with new innovations and contribute to a strong knowledge-sharing culture.
Job responsibilities - Develop and deploy state-of-the-art advanced machine learning systems across NLP, speech recognition, recommendation systems and information retrieval.
- Design and build agentic AI systems for multi-step workflows, including tool/function calling, multi-agent orchestration, planning, grounding, and safety guardrails.
- Use reinforcement learning (policy optimization, bandits, RLHF-style approaches where appropriate) to improve personalization, dialog policies, and sequential decision-making systems.
- Fine-tune and adapt LLMs/SLMs using PEFT (LoRA, AdaLoRA, IA3), distillation, and quantization; optimize for quality, latency, cost, and production constraints.
- Select and innovate on ML strategies for various banking problems.
- Analyze and evaluate the ongoing performance of developed ML systems.
- Collaborate with multiple partner teams, such as Business, Technology, Product Management, Design, Analytics, and Model Governance to deploy solutions into production.
- Build domain understanding to identify high-impact opportunities, ensure responsible AI usage, and drive measurable outcomes (customer experience, automation, accuracy, and efficiency).
- Implement privacy, safety, and security controls for GenAI systems, including PCI handling/redaction, policy checks, jailbreak resistance, and auditability.
Required qualifications, capabilities, and skills - BS with 5+ years, or MS with 3+ years of hand-on industry experience in building and deploying machine learning systems (NLP/Information Retrieval/Recommendation System and/or GenAI) in production environment
- Good understanding of the latest advancement of NLP concepts, such as the transformer architecture, knowledge distillation, transfer learning, and representation learning.
- Applied GenAI experience with LLMs and the ability to fine-tune and deploy SLMs for targeted use cases, familiarity with prompt design, grounded generation, and RAG.
- Experience with scaling LLM systems (caching, batching, prompt/version governance, evaluation harnesses)
- Strong foundation in machine learning, deep learning, and statistical modelling, including model evaluation and error analysis.
- Solid understanding of Information Retrieval concepts (indexing, ranking, dense/sparse retrieval, re-ranking) and/or recommendation systems.
- Ability to design experiments - establish strong baselines, choose meaningful metrics, and evaluate model performance rigorously
- Scientific thinking with the ability to invent and to work both independently and in highly collaborative team environments
- Proficiency in Python and common ML libraries (PyTorch/TensorFlow, Hugging Face, scikit-learn), and ability to write production-quality code.
- Ability to collaborate in cross-functional environments with product, engineering, and control partners.
- Solid written and spoken communication skills
Preferred qualifications, capabilities, and skills
- 2 years of hands-on experience with virtual assistant model development and optimization
- Experience orchestrating multi-agent teams with supervisor agents, debate/consensus mechanisms, and role-specialized toolkits for complex enterprise tasks.
- Building agent governance and eval suites: red-teaming, adversarial tests, safety scorecards, regression suites for prompts/tools
- Experience with RL/bandits, preference optimization, or human feedback loops for personalization.
- Experience in regulated finance domains and working with risk/control processes.
- Experience with MLOps/LLMOps: CI/CD for models, monitoring/alerting, model versioning, evaluation of pipelines, and rollback strategies.
- Experience with A/B experimentation and data/metric-driven product development.
