As a Senior AI Engineer, you will be at the forefront of Generative AI and LLM-driven innovation, leading the design, development, and deployment of next-generation AI solutions for capital markets and investment applications. Your work will span fine-tuning LLMs, retrieval-augmented generation (RAG), multimodal AI, and reinforcement learning, integrating these technologies into high-impact financial systems.

We are looking for a practical AI leader who can experiment rapidly, optimize AI pipelines, and build scalable, production-grade AI/LLM solutions. You will also guide junior engineers, collaborate with investment and technology teams, and ensure that AI initiatives align with real-world financial and operational needs.

ROLES AND RESPONSIBILITIES

• Architect, fine-tune, and deploy large-scale LLMs and GenAI models, optimizing them for investment, trading, and financial analytics use cases.
• Leverage advanced techniques such as prompt engineering, retrieval-augmented generation (RAG), fine-tuning, and multimodal AI to enhance LLM effectiveness in financial decision-making.
• Integrate AI/ML solutions into real-world workflows, ensuring seamless deployment and reliability in high-stakes trading and investment scenarios.
• Optimize AI inference pipelines for speed, efficiency, and scalability in production environments.
• Evaluate and experiment with the latest AI research (e.g., OpenAI, Anthropic, DeepMind, Hugging Face, open-source LLMs) to assess their applicability to finance and trading.
• Develop robust data pipelines for training and inference, ensuring high-quality and unstructured data feeds for AI models.
• Collaborate with financial, quantitative, and engineering teams to align AI solutions with business objectives.
• Contribute to the AI strategy roadmap, identifying key opportunities for GenAI adoption across the firm.
• Ensure security, compliance, and risk considerations are embedded in all AI/ML deployments.

KEY REQUIREMENTS

• 6+ years of experience in AI/ML, with a strong focus on Generative AI, LLMs, or deep learning.
• 5+ years of experience in training, fine-tuning, and deploying LLMs (e.g., GPT, LLaMA, Mistral, Falcon).
• 3+ years of experience building production-grade AI applications and integrating models into cloud-based or on-prem systems.
• 3+ years of experience in NLP, deep learning, reinforcement learning, and/or multimodal AI.
• 3+ years of experience with cloud platforms (AWS, GCP, or Azure) for deploying scalable AI/ML solutions.
• Solid experience in Python and AI/ML frameworks such as LangChain, Hugging Face, PyTorch, and TensorFlow.
• Understanding of prompt engineering, zero-shot learning, and LLM inference optimization.
• Strong software engineering skills, including containerization, CI/CD, and DevOps for AI, are mandatory.
• Ability to lead projects and mentor junior engineers while working cross-functionally with researchers and business teams.
• Prior experience with reinforcement learning (e.g., RLHF) and autonomous agent-based AI systems is desirable.
• Familiarity with vector databases (e.g., Pinecone, Weaviate, FAISS) and retrieval-augmented generation (RAG) pipelines is desirable.
• Hands-on experience with big data processing frameworks (e.g., Spark, Ray, Dask) for large-scale AI workloads is desirable.
• Contributions to open-source AI projects, publications, or AI research are desirable.
• Excellent problem-solving skills and attention to detail in optimizing AI pipelines.
• Effective time management to balance research, experimentation, and deployment.
• Good understanding of AI governance, security, and compliance considerations.
• Prior experience working in hedge funds, investment banks, or financial markets is desirable.
• A Master's or PhD in AI, Machine Learning, NLP, or a related field is desirable.
