About the Role We are looking for a Data & Security Engineer to build, maintain, and secure analytics infrastructure for a prediction market platform (Forkast). This role sits at the intersection of data engineering, on‑chain analytics, and security, with a strong focus on trade activity analysis, dashboarding, and anomaly detection. You will be responsible for transforming raw on‑chain and off‑chain data into actionable insights, powering Hex dashboards, Dune Analytics, and internal monitoring systems that support product decisions, risk management, and market integrity. Responsibilities Data & Analytics: Design and maintain Hex dashboards for real‑time and historical market insights. Build and optimize Dune Analytics queries for on‑chain trade activity, liquidity, user behavior, and market performance. Analyze trade activity across prediction markets to identify patterns, trends, and anomalies. Develop data pipelines to ingest, clean, and normalize blockchain and application‑level data. Support forecasting and prediction market analytics (volume, liquidity, pricing efficiency, trader behavior). Security & Risk: Monitor markets for suspicious trading behavior, manipulation, wash trading, or oracle exploitation. Build alerts and dashboards for risk and security events. Collaborate with protocol and smart contract teams to assess data‑related security risks. Ensure data integrity, access control, and best practices for sensitive analytics infrastructure. Prediction Market Intelligence: Support Forkast market design with data‑driven insights. Analyze market resolution accuracy, trader incentives, and pricing signals. Create metrics to evaluate market health and predictive performance. Requirements Technical Skills: Strong experience with SQL (especially for Dune Analytics). Hands‑on experience building Dashboards in Hex (or similar BI tools). Familiarity with blockchain data (Ethereum or EVM chains preferred). Experience analyzing on‑chain trade activity and user behavior. Solid understanding of data security principles and monitoring systems. Nice to Have: Experience with prediction markets, DeFi, or financial markets. Knowledge of smart contracts, oracles, and on‑chain risk vectors. Python or similar language for data processing and automation. Experience with anomaly detection or fraud analysis. Familiarity with Forkast or similar platforms (Polymarket, Kalshi, etc.). What we are looking for? Strong analytical mindset with attention to detail. Ability to translate raw data into clear, decision‑ready insights. Security‑conscious approach to data and infrastructure. Comfortable working in fast‑moving, crypto‑native environments. Proactive problem solver who can work independently. Why Join Us? Work on cutting‑edge prediction market technology. High ownership over data and security architecture. Remote‑friendly, flexible working environment. Opportunity to shape market integrity and analytics at scale. #J-18808-Ljbffr
