Stockwiz is one of India's fastest-growing wealth-tech platforms, simplifying trading and investing for over 30,000 active retail users. As a SEBI-registered firm, we work at the intersection of education, advisory, and trading technology. Our products include Stryke (smart trading app), StrykeX (algo trading platform), and WizOps (internal operations platform).

The Role

We're hiring a Principal Engineer to lead our backend and AI/ML teams and own the technical foundation of our trading products. This is our most senior engineering role — a hands-on technical authority who sets direction, writes and reviews critical code, mentors developers, and owns the standards that keep a real-money trading platform reliable. When there's a hard problem — a performance bottleneck, a tricky bug, a risky deployment, or a misbehaving model — you're the person who gets to the bottom of it.

What You'll Do

• Own end-to-end architecture and technical quality across all products, including new builds.
• Write, review, and approve production code (including AI-generated code) and validate trading logic for correctness.
• Design and operate asynchronous/background processing systems (Celery, task queues, schedulers) that power execution, signals, and data pipelines.
• Define and enforce deployment, testing, and code-review standards.
• Lead the AI/ML team — model development, training, deployment, monitoring, and serving in production.
• Oversee vector databases and retrieval systems powering AI features such as the StrykeX AI Copilot.
• Ensure AI/ML systems are reliable, explainable where required, and aligned with SEBI regulatory constraints.
• Lead, mentor, and manage backend and AI/ML developers; help hire and raise the bar across the team.

What You'll Need

Backend & Systems

• Strong hands-on Python backend development.
• Deep experience with PostgreSQL, MongoDB, Redis (time-series stores like QuestDB a plus).
• Hands-on Celery and asynchronous/background task processing at scale.
• Solid grasp of system architecture, APIs, and the full development-to-deployment lifecycle.
• Track record of shipping reliable, high-availability systems — ideally in fintech or another high-stakes domain.

AI / ML

• Hands-on with PyTorch and/or TensorFlow.
• Strong command of NumPy, pandas, scikit-learn.
• Experience deploying and serving models in production (FastAPI, ONNX, containerized inference).
• Practical LLM experience — prompt design, RAG pipelines, embeddings, and orchestration (LangChain or similar).
• Experience with vector databases (Pinecone, Weaviate, pgvector, Qdrant, or similar).
• Understanding of the full MLOps lifecycle.

Leadership

• Proven experience leading or mentoring engineering and/or AI/ML teams.

Preferred

• Trading systems, algorithmic trading, or low-latency/high-throughput platforms.
• ML applied to financial/time-series data (forecasting, signal generation, anomaly detection).
• AWS infrastructure (EC2, RDS, load balancers, VPCs) and websocket-based services.
• MLOps tooling (MLflow, Weights & Biases); GPU-based training.
• Familiarity with SEBI/regulatory considerations in fintech.

What We Offer

• The chance to architect and lead products defining the next wave of retail trading in India.
• A high-ownership, high-impact role with direct influence over technical direction.
• Competitive compensation with performance-based incentives.
• Strong growth in a rapidly expanding fintech startup.
