Data Engineer

Senior Data Engineer (Monitoring & Parameter Systems)

Location: Porto, Portugal OR New York, NY (Full-Time)

Category: Engineering / Data Science

Compensation: $140K - $300K

We are on a simple mission: to make it possible for anyone with a digital wallet to trade stocks, commodities, currencies, and crypto with full transparency. We are replacing the opaque, offshore brokerage model with a transparent, permissionless trading stack built entirely on-chain. Every trade, deposit, and withdrawal on our platform is verifiable through open, auditable code.

To date, we have raised $27.9M+ from top-tier investors including General Catalyst, Jump, Susquehanna (SIG), Alliance DAO, and Balaji Srinivasan.

We are seeking a Data Engineer (Monitoring & Parameter Systems) to architect and operate the analytics, observability, and parameter-proposal infrastructure that keeps our protocol safe and economically sound. You will serve as the critical bridge between protocol mechanics—such as fees, spreads, and liquidations—and production-grade data systems. Your mandate is to translate complex economic models into reliable pipelines and monitoring services that ensure the protocol remains healthy across all markets.

Responsibilities

• Data Pipelines: Architect and maintain robust ingestion and transformation pipelines for on-chain events and market data using AWS-native services.
• Parameter Proposal Systems: Implement mathematical parameter models (dynamic spreads, risk limits, funding controls) as reproducible code, producing versioned artifacts for protocol upgrades.
• Monitoring & Observability: Design Grafana dashboards and alerting systems for protocol health and economic correctness (execution costs, fee accrual, oracle quality, etc.).
• Backtesting & Validation: Build testing and "replay" frameworks to validate proposed parameter changes against historical data and stress scenarios.
• Productionization: Package models and pipelines into reliable services with CI/CD, automated data quality checks, and continuous output monitoring.

Requirements

• Data Engineering Fluency: Strong proficiency in Python (pandas, numpy) and SQL, with experience designing analytics schemas for time-series and high-frequency trading data.
• AWS Mastery: Hands-on experience with the core AWS stack, including S3, Athena/Glue, Redshift, ECS/EKS, and Lambda.
• Observability Expertise: Proven ability to build monitoring systems using Grafana (ideally with Prometheus/Loki), including metrics definition and incident response workflows.
• Production Mindset: Experience turning research-heavy logic into robust, versioned libraries/services with full CI/CD integration.
• Education: Degree in Computer Science, Engineering, or a related quantitative field.

Preferred Qualifications:

• A Data Scientist mindset: Experience building/validating statistical models for parameter tuning or anomaly detection.
• DeFi/Trading Domain Knowledge: Familiarity with PnL, funding/rollover mechanics, and the specific "quirks" of on-chain event streams.
• Blockchain Tooling: Experience with indexing tools (Subgraphs, Dune, RPC parsing) and handling smart contract schema drift.
• Modern Data Stack: Familiarity with orchestration and quality tools like Airflow/Dagster, dbt, and Great Expectations.

Benefits

• High-Stakes Impact: Help architect the economic safety systems for a $27M+ backed RWA protocol.
• Cutting-Edge Tech: Work at the frontier of blockchain technology and decentralized finance.
• Competitive Package: High-tier salary plus tokens and equity.
• Collaborative Environment: Join a team of highly skilled engineers and researchers in a flat, fast-moving structure.
• Flexibility: Modern work arrangements with professional development support.
