Senior Data Platform Engineer

ABOUT PROVABLE At Provable, our mission is to redefine trust and privacy in the digital world. By creating tools that simplify the complexities of zero-knowledge technology, we empower developers to build applications that prioritize security, user control and scalability. We envision a future where privacy is not an afterthought but a fundamental standard, enabling a more secure and equitable Web3. THE ROLE Provable is seeking a Senior Data Platform Engineer to own and scale our data infrastructure, pipelines, and data-serving APIs on Google Cloud Platform (GCP). In this hybrid role, you will manage the end-to-end data lifecycle: ingestion from our Aleo L1 blockchain indexers, pipeline processing, and the APIs that serve this data to our mobile privacy wallets and blockchain explorer. This position is roughly a 60/40 split between core data engineering (infrastructure, pipelines, indexing) and backend software engineering (API development and database optimization). The ideal candidate understands blockchain data structures and is eager to solve the unique challenges of indexing zero-knowledge, privacy-focused networks. RESPONSIBILITIES - Design, implement, and maintain scalable and reliable data infrastructure in GCP.

• Build and optimize data pipelines fed by blockchain indexers to support our blockchain explorer, API, and analytics.
• Design data models that effectively handle the unique privacy and cryptographic constraints of Aleo’s zero-knowledge network architecture.
• Own, develop, and optimize APIs that serve data directly to our mobile privacy wallets and external products.
• Manage and optimize database technologies, with a focus on Postgres and BigQuery.
• Ensure data quality, reliability, and observability through monitoring, logging, and automated alerting.
• Collaborate with product and engineering teams to understand requirements and deliver high-performance APIs.
• Identify opportunities to optimize the performance and cost of data platforms.
• Utilize infrastructure-as-code (Terraform and Helm) to deploy and manage data environments.
• Help define the technical vision and evolution of our data platform and architecture.

• Strong proficiency in Node.js / TypeScript for API development and Python for data scripting.
• Expert-level SQL and deep experience optimizing relational databases (Postgres) and cloud data warehouses (BigQuery).
• Proficiency with cloud infrastructure automation, specifically Terraform and Kubernetes (GKE).
• Excellent communication skills with a track record of taking end-to-end ownership of critical technical initiatives.

• Deep understanding of Web3 infrastructure, blockchain data structures, and ZK-rollups or privacy networks.
• Experience implementing monitoring and observability solutions (Prometheus, Grafana, or GCP native services).

• Highlight hands‑on experience with GCP services (BigQuery, Dataflow, Pub/Sub, Cloud Composer) in your resume and interview; bring a short, 2‑minute walkthrough of a production pipeline you built on GCP that ingests blockchain data, transforms it, and serves it via an API.
• Build a mini‑project that mirrors Provable’s data flow: pull Aleo L1 block data (or any public blockchain), process it with Apache Beam/Scala or Python, store results in BigQuery, and expose a RESTful endpoint using Cloud Functions or Cloud Run. Include the repo link, a README that explains architecture, and screenshots of performance metrics.
• Emphasize security‑by‑design practices: describe how you encrypted data at rest/in‑flight, applied IAM least‑privilege, and used VPC Service Controls. Bring concrete examples of audit logs or compliance checks you’ve implemented for privacy‑sensitive pipelines.
• Leverage your Excel expertise as a “data sanity” tool: prepare a one‑page sample showing how you used advanced Excel (Power Query, PivotTables, VBA) to validate raw blockchain extracts before they entered the pipeline, and mention how this complements automated ETL testing.
• During salary negotiation, reference market data for senior GCP data engineers in the Web3 space (e.g., $180k‑$210k base + equity). Ask for a performance‑based equity tranche tied to measurable metrics like “X TB of data processed per month” or “API latency < 50 ms for wallet queries,” showing you understand Provable’s growth goals.
