PS is rapidly becoming the leading solution for quality multi-sourcing and end-to-end automated research solution.
The Opportunity:
We are looking for a Data Scientist to join our Data Science & AI team in Hyderabad. In this role, you will bring your deep expertise in fraud detection and threat mitigation, into the dynamic ecosystem of Market Research. We need a highly technical, hands-on builder who can architect real-time anomaly detection systems and isn't afraid to get into the weeds of feature engineering and distributed computing.
Beyond core fraud detection, you will act as a technical leader and trusted advisor. You will design Agentic AI systems to automate process workflows, build core product analytics, and guide cross-functional teams (PMs and engineering) through modeling choices. You understand that deploying ML is as much a people and business challenge as it is a technical one, and you thrive in a high-velocity, dynamic environment.
Location: Remote (mapped to Hyderabad, India)
What You’ll Do
- Architect Real-Time Risk & Fraud Systems: Design, train, and deploy high-throughput machine learning models to detect identity spoofing, survey fraud, and bot nets. Expand these capabilities into broader cybersecurity risk scoring, threat intelligence, and vendor risk assessments.
- Process large scale transaction data: Build robust, distributed data pipelines to ingest massive transaction volumes. Perform deep exploratory data analysis (EDA) to identify complex behavioral patterns and anomalies.
- Lead Technical Groundwork & Best Practices: Take ownership of the end-to-end ML lifecycle. Drive engineering excellence by actively contributing to code reviews, system design discussions, and establishing robust data science methodologies across the team.
- Cross-Functional Prototyping & Expansion: Translate ambiguous customer and business needs into concrete ML solutions. Design and build prototypes across varied platform use cases, optimizing data quality and sample delivery. Design and interpret back tests or offline evaluations for ML and rules-based systems.
- Drive Agentic AI Innovation: Build autonomous AI agents (leveraging LLMs and RAG) to monitor external channels (e.g., scraping online forums for threat intelligence), enforce data quality, and automate operational overhead like code documentation.
- Advise & Communicate: Effectively communicate modeling choices, trust, and interpretability while delivering demos, executive presentations, and clear rollout plans.
What You Bring (Must-Haves)
- Education: Advanced degree (Master’s) in a quantitative STEM field (Computer Science, Statistics, Mathematics, Engineering, Physics) or equivalent professional experience solving complex analytical problems.
- Experience: 5+ years of hands-on, production-level experience applying data science to real-world challenges, ideally within a high-growth tech, cybersecurity, or product-driven startup environment.
- Advanced ML & Stats Fundamentals: Deep theoretical and practical knowledge of statistical modeling, anomaly detection, evaluation metrics, and experimentation frameworks.
- Programming Mastery: Production-level coding proficiency in Python and advanced SQL.
- Cloud & ML Frameworks: Deep expertise with traditional ML libraries (Scikit-learn, XGBoost) and modern cloud-based MLOps pipelines (AWS, GCP, Databricks, MLFlow).
- Domain Expertise: A proven track record in fraud detection, cybersecurity, threat intelligence, or risk scoring.
- Communication & Leadership: Excellent stakeholder-management skills. You are comfortable navigating diverse teams, partnering with product management, and communicating complex findings to non-technical audiences.
Nice-to-Haves
- GenAI & LLMs: Genuine enthusiasm and hands-on exposure to modern LLMs, modern modeling approaches, and deploying Agentic AI for business workflows.
- Intellectual Curiosity: A visible track record of your craft via GitHub profile showcasing personal ML/AI projects, open-source contributions, research publications, hackathon participation or strong rankings in Kaggle competitions (especially in fraud or anomaly detection tracks).
