DV Labs is building the next generation of distributed validators to make Ethereum staking more resilient, decentralized, and secure.

Our software allows groups of operators—large and small—to collaboratively run a single validator while minimizing single‑point‑of‑failure risk and maximizing client diversity. We are a venture‑backed, remote‑first team that values open‑source ethos, long‑term thinking, and empirical decision‑making.

We are searching for a dedicated Data Engineer to design, build, and own the data platform that powers product decisions, validator‑performance analytics, on‑chain research, and community transparency.

Responsibilities

• Ingest & model Beacon‑chain data — blocks, attestations, sync‑committee aggregates, deposits, and slashings—into ClickHouse and MongoDB at multi‑TB scale.
• Develop scalable ETL/ELT pipelines in Apache Spark (PySpark/Scala) orchestrated via GitHub Workflows and containerized CI/CD.
• Implement columnar schemas & partition strategies to achieve sub‑second analytical queries and reduce storage footprint.
• Expose clean, version‑controlled datasets & metrics to internal stakeholders through APIs, dashboards, and notebooks.
• Collaborate with Protocol & DevOps teams to surface validator health, slash‑risk events, and protocol‑level anomalies in real time.
• Own data quality, lineage, testing, and documentation across the stack; champion best practices and continuous improvement.
• Contribute to open‑source tooling around consensus‑layer data, distributed‑validator monitoring, and Ethereum research.

Requirements

• 2+ years of professional experience in data engineering or high‑performance backend roles.
• Production expertise with ClickHouse and Apache Spark on multi‑terabyte datasets.
• Hands‑on experience operating MongoDB for semi‑structured/operational workloads.
• Proficiency in Python (pandas/PySpark) and/or Scala; solid Git and CI/CD habits (GitHub Actions/Workflows or similar).
• Deep understanding of the Ethereum consensus layer (Beacon chain architecture, validator lifecycle, slashing conditions, client diversity—Lighthouse, Prysm, Teku, etc.).
• Comfortable working in a remote, asynchronous startup environment with high ownership and autonomy.

Nice to have

• Familiarity with Ethereum execution‑layer JSON‑RPC, MEV‑Boost, and block‑building economics.
• Experience operating distributed systems on Kubernetes, Nomad, or similar orchestrators.
• Fluency in Python.
• Exposure to data‑observability stacks (dbt, Great Expectations, Dagster) and time‑series monitoring (Prometheus/Grafana).
• Prior contributions to web3 or other open‑source projects.

About the team - How we work?

• Async‑first: proposals & design docs precede meetings.
• Small, senior team: high trust & ownership.
• Open‑source by default: most code and discussions are public.

Our Values

• Synergistic
• Secure
• Innovative
• Reliable

Compensation

• Competitive salary in dollars
• Full remote company - Work from wherever you want
• Possibility to attend to relevant Conferences
• 2 Recharge weeks at the end of the year
• Equipment budget
