Key Responsibilities include (but will not be limited to)

• End-to-End Product Ownership

You'll work directly with stakeholders to translate regulatory and business requirements — jurisdiction-specific rules, standards, thresholds — into production-ready features and deployable models. You own the problem from whiteboard to deployment.

• NLP \& Model Orchestration

Design, fine-tune, and maintain advanced text classification pipelines (e.g., ELECTRA, RoBERTa). You'll continuously evaluate model performance and drive improvements.

• RAG \& Knowledge Integration

Build and enhance Retrieval-Augmented Generation systems backed by vector databases.

• Generative AI Pipelines

Develop and scale generative models.

• Agentic Systems

Engineer agentic workflows and Q\&A systems that allow users to interact with reports.

• Visual \& Data Integrity Auditing

Apply Computer Vision and OCR techniques to audit graphs, tables, and visual data — verifying axis consistency, scale uniformity, and alignment with sources.

• Automated Reporting

Architect systems that generate structured reports that's actionable for both technical and non-technical stakeholders.

• MLOps \& Model Governance

Own the full model lifecycle: manage retraining cycles, version control, and performance monitoring. Maintain a clean, auditable Git history that scales as the team grows.

Requirements \& Qualifications

• Education

Bachelor's or Master's in Data Science, Computer Science, Statistics, or a related field. Equivalent experience with a strong portfolio will be considered.

• Experience

5 years of professional experience in applied ML or data science. Prior experience in a startup or small high-impact team is a strong plus — we're looking for people who are comfortable with ambiguity and ownership in equal measure.

• Core Technical Stack

Hands-on production experience with PyTorch or TensorFlow, Hugging Face Transformers, and SQL/NoSQL databases.

• LLM \& RAG Expertise

Demonstrated experience building with Large Language Models for semantic search, feature engineering, or RAG architectures. You understand not just how to use LLMs, but when not to.

• Autonomous \& Product-Minded

You can take a vague requirement, define the problem, build the solution, and ship it — without waiting to be told what to do next. You think about tradeoffs: speed vs. interpretability, precision vs. recall, simplicity vs. capability.

• Engineering Discipline

You write code that other people can read, extend, and trust. Strong Git hygiene, documentation habits, and a mindset toward long-term maintainability over short-term shortcuts.
