We are seeking a deeply technical Backend SDE-4 / Principal Engineer to join our global engineering team at a leading Fintech product company operating in the US and India. In this critical, hands-on leadership role, you will work at the intersection of applied machine learning and platform engineering.

You will not be building AI chatbots or LLM wrappers; you will be solving the hardest architectural and performance problems across our ML infrastructure. Utilizing a combination of Python and Node.js, you will design scalable tools and systems that accelerate model development. You will ensure our backend architecture can handle massive financial datasets and meet the rigorous security, latency, and performance standards of the financial sector.

Key ResponsibilitiesAdvanced ML System Design & Infrastructure

Architectural Leadership: Architect the end-to-end platform for our ML systems. Design for high availability, fault tolerance, and extreme scalability to serve multiple business domains within the firm.
High-Performance Pipelines: Design and build ML systems and reproducible,



high-performance training pipelines across our infrastructure.
Inference Architecture: Architect inference systems that balance latency, throughput, cost, and reliability at scale. Define the abstractions, APIs, and reusable components that make solution-building repeatable.
Platform Innovation: Build a unified platform for training, serving, and managing representations at scale, and streamline feature engineering pipelines to reduce manual steps.

Deep Learning & Machine Learning Engineering

Algorithm Implementation: Apply state-of-the-art techniques and core ML frameworks (e.g., PyTorch, TensorFlow, Scikit-learn, XGBoost) to extract structured insights from complex financial data.
Model Optimization: Implement automated continuous-learning systems that handle data refresh, retraining, evaluation, and monitoring to improve predictive accuracy in production.
Backend Integration: Collabo
