Be an Early Applicant
Build, train, evaluate, and deploy machine learning and generative AI models for fraud detection, financial agents, and safety systems. Develop high-throughput data and inference pipelines using distributed technologies, optimize GPU model serving, maintain feature stores, fine-tune language models, and implement evaluation guardrails. Collaborate with architects and engineers while applying MLOps, cloud, containerization, and software engineering practices.
Key Responsibilities:
1. Hands-On Execution (The "What")
- Model Development: Build, train, and evaluate ML and GenAI models, taking them from experimentation to production with guidance from senior engineers.
- Pipelines: Implement and maintain data and inference pipelines, ensuring they meet reliability and latency targets.
- Collaboration: Work closely with senior architects and engineers, contributing to code reviews and learning production best practices.
2. Predictive AI & Scale (The "Fast")
- Fraud at Scale: Contribute to our Fraud Risk Management (FRM) system, building features and models for streaming inference using Flink/Spark.
- Feature Store: Help build and maintain features that serve both high-velocity transactional data and dense vector embeddings.
- Optimization: Profile and optimize model serving to improve throughput on our GPU clusters.
3. Generative & Agentic AI (The "Smart")
- AI Agents: Support the development of AI Agents that navigate banking interfaces, execute refunds, and detect social engineering attacks.
- LLM Fine-Tuning: Assist in fine-tuning SLMs (Small Language Models) on secured financial data for edge deployment.
- Safety Guardrails: Implement guardrails and evaluations that prevent hallucination in critical financial advice.
The Ideal Candidate Profile : You are a hands-on builder.
- You love to code, you are curious about how things work end-to-end, and you are eager to grow into a scale-veteran engineer.
- Essential Experience (3+ Years)
- Dual Exposure: Hands-on experience in Classic ML AND/OR Modern GenAI (LLMs/Agents).
- Bonus if you have shipped either type of system to production.
- Scale Curiosity: Experience working with production systems and a strong desire to understand high-throughput, distributed computing.
- Deep Learning Fundamentals: Solid grasp of ML/DL fundamentals and the underlying math.
- Familiarity with Transformers or GNNs is a plus.
- Collaboration: Comfortable working in cross-functional teams and aligning your work with business goals.
Must-Have Skills
-
- Programming: Strong proficiency in Python and solid software engineering fundamentals (clean code, version control with Git, testing).
- Core ML: Hands-on experience building, training, and evaluating ML models using scikit-learn, XGBoost/LightGBM, and PyTorch or TensorFlow.
- GenAI / LLMs: Practical experience with LLMs – prompt engineering, RAG, fine-tuning, and frameworks such as LangChain/LangGraph and Hugging Face
Transformers.
- Data Handling: Strong SQL and data wrangling skills (Pandas/NumPy); experience working with large datasets.
- Big Data / Pipelines: Working experience with Spark or Kafka/Flink for building data and inference pipelines.
- Deployment: Experience containerizing and deploying models (Docker), exposing them via REST/gRPC APIs, and basic familiarity with Kubernetes.
- MLOps: Exposure to experiment tracking and model lifecycle tools (MLflow) and CI/CD for ML.
- Cloud: Hands-on with at least one major cloud platform (AWS, GCP, or Azure).
- Fundamentals: Solid grasp of statistics, probability, and deep learning concepts (including Transformer architecture).
- Communication: Ability to clearly document work and collaborate within cross-functional teams.
Technical Stack
- ML Ops: Kubernetes, Kubeflow, Ray, MLflow.
- Big Data: Spark, Kafka, Flink, Iceberg/Hudi.
- GenAI: vLLM, LangGraph, DeepSpeed, Unsloth.
- Cloud/Infra: Working knowledge of GPU/TPU usage and cost awareness.
The Package
Growth: Learn directly from Principal Architects and senior engineers shaping the nation's AI.
Resources: Access to state-of-the-art compute infrastructure and proprietary datasets that are unique in the world.
Legacy: The opportunity to say, "I helped build the AI that powers the Indian Economy."
