Ostium is on a simple mission: make it possible for anyone with a digital wallet to trade stocks, commodities, currencies, and crypto with full transparency. No brokers, no freezes, no hidden spreads. We’re replacing the opaque, offshore brokerage model with a transparent, permissionless trading stack built onchain. Every trade, deposit, and withdrawal is verifiable through open, auditable code. We’ve raised $27.9M+ from General Catalyst, Jump, LocalGlobe, Susquehanna (SIG), GSR, Alliance DAO, Soma Capital, Balaji Srinivasan, Meltem Demirors, and others.
Data Engineer (Porto OR New York / Full-Time)We are seeking a Data Engineer (Monitoring & Parameter Systems) to build and operate the analytics, observability, and parameter-proposal tooling that keeps Ostium safe and economically correct. You will be the bridge between protocol mechanics (fees, spreads, rollover, liquidations) and production-grade data systems. Your mandate is to translate models and parameter frameworks into reliable pipelines, monitored services, and dashboards that ensure the protocol consistently charges the right values across markets.
Responsibilities
Data Pipelines: Architect and maintain robust ingestion and transformation pipelines for on-chain events and market data using AWS-native services and scalable storage/query layers.
Parameter Proposal Systems: Implement parameter models (dynamic spreads/impact, OI caps, risk limits, funding/rollover controls) as reproducible code, producing versioned proposal artifacts for review.
Monitoring & Observability: Design Grafana dashboards and alerting for protocol health and economic correctness (execution costs, fee accrual, oracle quality,
liquidations, OI usage), with clear runbooks.Backtesting & Validation: Build testing and replay frameworks to validate parameter changes on historical data, detect regressions, and quantify impact under stress scenarios.
Productionization: Package models and pipelines into reliable jobs/services with CI/CD, automated tests, data quality checks, and continuous monitoring of outputs.
Data Engineering Fluency: Strong experience in Python and relevant libraries for production pipelines (pandas/numpy), plus strong SQL and experience designing analytics tables/views for time-series and trading data.
AWS Experience: Hands-on with core AWS tooling (e.g., S3, Athena/Glue, Redshift, ECS/EKS/Lambda, CloudWatch).
Observability Experience: Proven ability to build monitoring systems with Grafana (and ideally Prometheus/Loki/Tempo), including alerting, metrics definition, and incident response workflows.
Production Mindset: Experience turning research logic into robust libraries/services with testing, versioning, CI/CD, and reproducible environments
Data scientist mindset and experience building/validating models or statistical checks (e.g., parameter tuning, anomaly detection, backtesting-style evaluation) and translating them into production metrics.
Familiarity with DeFi or trading data (PnL, funding/rollover, leverage, liquidation mechanics) and the quirks of on-chain event streams.
Experience with blockchain indexing tools (Subgraphs/The Graph, Dune, RPC log parsing) and handling schema drift across protocol upgrades.
Experience with orchestration and data quality tooling (Airflow/Prefect/Dagster, dbt, Great Expectations/Soda) and building reliable data contracts.
Competitive compensation package
Opportunity to work with cutting-edge blockchain technology
Collaborative environment with highly skilled team members
Flexible work arrangements
Professional development opportunities
This role is perfect for someone who is excited about building reliable data infrastructure and monitoring systems, enjoys shipping production-grade analytics, and wants to operationalize the models and parameters that power on-chain RWA trading.
Interested candidates should submit their resume, GitHub profile, and links to relevant projects demonstrating production data pipelines, monitoring/alerting systems, or deployed modeling
workflows.
