Hey!!  Update Your CV Like a Pro. HERE are Tips from an Experienced Recruiter

Data Engineer at Ethena Labs, Remote (Global)

The Senior Data Engineer is a critical role reporting directly to the CTO. The primary mission is to rapidly deliver a reliable, production-ready market data platform that serves as the single source of truth for trading, risk, and business intelligence.

You’ll immediately own the entire data platform from inception and deliver working historical and real-time Tardis pipelines in the first 60 days. Beyond the initial MVP, the role requires iteratively evolving the platform into a best-in-class, cloud-native, observable, and self-service system. You will work hand in hand with the CTO & trading team to scope & deliver to business needs. The Senior Data Engineer will also serve as the go-to data expert for the firm and will be responsible for mentoring future junior data engineers or analysts.

What You’ll Do

• Rapidly spin up the cloud environment. Deliver working historical backfill pipelines from Tardis.dev into a queryable database.
• Deliver a real-time Tardis WebSocket pipeline, ensuring data is normalized, cached for live consumption, accurate, replayable, and queryable by Day 60.
• Ensure all pipelines are idempotent, retryable, and use exactly-once semantics. Implement full CI/CD, Terraform, automated testing, and secrets management.
• Implement proper observability (structured logs, metrics, dashboards, alerting) from day one. Provide immediate self-service access to the MVP database for Trading and BI teams via tools like Tableau/Metabase, and through simple internal REST APIs.
• Develop specialized timeseries data, including USDe backing-asset and a full opportunity-surface timeseries for Delta-neutral/lending/borrow opportunities.
• Ingest data from additional sources (Kaiko, CoinAPI, on-chain via TheGraph/Dune). Plan for 10x+ data growth via schema evolution, partitioning, and performance tuning. Establish enterprise-grade governance, including a data quality framework, RBAC, audit logs, and a semantic layer.
• Create full architecture documentation, runbooks, and a data dictionary. Onboard and mentor future junior staff.

What We’re Looking For

• Proven track record of delivering working, production data in weeks, not months, with the ability to ruthlessly cut scope to hit a 60-day MVP while managing technical debt.
• Have built Tardis historical and real-time pipelines before (or equivalent high-quality crypto market data feeds), understanding specific quirks, rate limits, and WebSocket structures.
• Expert in large-scale, reliable ETL/ELT for financial or market data.
• Fluent in provisioning full environments with Terraform in days and expert in AWS/GCP serverless technologies.
• Expert Python and SQL skills and proficiency with time-series databases like TimescaleDB or ClickHouse, ensuring fast queries from day one.
• Advanced knowledge of WebSocket clients, message queues, and low-latency streaming, GitOps, automated testing/deploy and observability practices.
• Significant understanding of stablecoins, lending protocols, and opportunity surface concepts, or a proven ability to ramp up extremely quickly.

You’d be joining a group that has well established itself as one of the most successful crypto-native company’s of all time, a group with a mission to revolutionise decentralised finance and it’s position in global finance.

Work alongside a passionate and innovative team that values collaboration and creativity.
