Senior Data Scientist

Senior Data Scientist

Experience: 4+ Years | Location: Bengaluru (Hybrid) |Team: Data Science & AI

About the Role

Akaike Technologies builds agentic AI and machine-learning systems that power decision-making for global enterprises. We want a Senior Data Scientist who understands what makes agentic systems reliable and can architect complex, high-accuracy, human-in-the-loop AI for demanding clients. Roughly 70% Generative AI and agents, 30% classical ML and large-scale data, with room to move across problems as priorities shift.

Key Responsibilities

Generative AI & Agentic Systems (primary focus)

• Agentic Systems: Design and ship production multi-agent systems (LangGraph/CrewAI; ReACT, Agent-Critique) that generate reliable, structured, high-accuracy outputs.
• Grounding & Reliability: Engineer grounding, source traceability, and hallucination control so outputs hold up in production and regulated settings.
• Evaluation: Build quantitative evaluation for generation quality - faithfulness, hallucination, consistency, and LLM-as-a-judge frameworks.
• Human-in-the-Loop: Design configurable, human-in-the-loop workflows (review gates, co-pilot editing) that scale across clients and use cases.
• Retrieval & Tuning: Build production RAG and agentic retrieval; apply PEFT/LoRA on open-source models (Llama 3, Mistral) where it beats prompting.

Classical ML & Data at Scale (secondary focus)

• Custom Modeling: Build bespoke models for targeting, budget optimization, and churn, including PU and single-class learning on sparse, noisy data.
• Applied Deep Learning: Apply 1D/2D CNNs, LSTMs, and embeddings to non-text data (time-series, behavioral logs) where they add real signal.
• Big Data: Write optimized PySpark/SparkSQL on Databricks over billions of rows, with feature stores consistent across training and inference.

Architecture, MLOps & Delivery

• System Design: Architect end-to-end systems with deliberate latency/cost/accuracy trade-offs and modular, reusable components.
• Measurement: Bring statistical rigor - offline and human eval, A/B where it fits, drift detection, and automated retraining.
• Deployment: Ship scalable pipelines on AWS (Bedrock, Lambda, Step Functions) and FastAPI.

Leadership & Stakeholders

• Mentorship & Clients: Mentor juniors, run rigorous code reviews, and serve as the technical point of contact for clients - explaining model limitations and risk without overselling.

Must-Have Skills

• Advanced GenAI/agent frameworks (LangChain, LlamaIndex, LangGraph, DSPy), with at least one agentic system or complex RAG pipeline shipped to production.
• PyTorch or TensorFlow; solid grasp of attention, encoder-decoder architectures, and embeddings.
• Expert PySpark and SQL; comfortable debugging and optimizing Spark on Databricks.
• Python (OOP, typing, rigorous standards) and a strong experimental / statistical mindset.
• Clear communicator who can explain complex AI - and its risks - to business leaders.

Nice to Have

• Pharma, life-sciences, or other regulated-domain background.
• Text-to-SQL, GraphRAG (Neo4j), or serving open-source models (vLLM/TGI).
• Custom loss functions / attention modifications, or open-source and publication contributions.

Benefits & Perks

• Competitive ESOP grants.
• Working with Fortune 500 companies and world-class teams.
• Publishing papers and attending conferences.
• Networking events, conferences, and seminars.
• Visibility across all functions at Akaike - sales, pre-sales, lead generation, marketing, and hiring.
