[Hiring] Senior Data Engineer @Solflare

Role Description

As a Senior Data Engineer at Solflare, you’ll build and optimize the data systems that power our product insights and decision-making. You’ll work closely with analysts, product managers, and engineers to:

• Design scalable pipelines
• Improve our data infrastructure
• Make reliable data accessible across teams

Our Data team was formed last year and currently has six people working across data analysis and engineering. The foundations are in place, but the team is still new enough for you to have a real impact on how we model data, design our systems, and work as a team.

The scale and variety of our data make this role especially interesting:

• Analyze user behavior at the individual transaction level across the wider Solana ecosystem
• Connect on-chain and off-chain data into a coherent user model
• Optimize pipeline performance and query-cost as on-chain data volumes grow

Our stack includes:

• BigQuery
• dbt Cloud
• Python
• GCP
• PostHog
• Dune
• Metabase
• Tableau

Claude Code is deeply integrated into our day-to-day work, so AI-assisted development is already the norm here, not an experiment.

We’re looking for an engineer who can not only build robust data systems but also help shape the technical direction of a growing Data team.

Core responsibilities:

• Data collection & preparation: Gather data from a variety of sources, ensuring it’s accurate, complete, and relevant to the business questions at hand.
• Design and build scalable data pipelines: Develop, maintain, and optimize ETL/ELT processes that collect, transform, and load data from multiple sources into our data warehouse.
• Data infrastructure: Manage and improve our data infrastructure using modern tools and cloud services (GCP), ensuring high availability and low latency.
• Automation & reliability: Automate data workflows, monitoring, and quality checks to ensure data consistency, accuracy, and reliability across all systems.
• Collaboration: Work with analytics and engineering teams to ensure data needs are met; from ingestion to analysis.
• Data integrity: Ensure that data is secure, well-documented, and accessible to those who need it most.

Qualifications

• 7+ years of professional experience as a Data Engineer or in a similar role dealing with large-scale data systems.
• Proficiency in Python, especially for building data processing pipelines.
• Hands-on experience with ETL/ELT tools (preferably dbt) and data orchestration.
• Experience with modern data warehouse technologies such as BigQuery, Snowflake, Redshift, or similar.
• Strong SQL skills and experience with both relational and NoSQL databases.
• Practical experience with cloud services (preferably GCP) for data storage, compute, and orchestration.
• Familiarity with Git and data CI/CD workflows for versioned, testable data deployments.
• Experience integrating AI tools (e.g. Claude Code) into your engineering workflow for faster iteration and higher-quality output.
• Solid experience using Excel or Google Sheets for quick analysis and pivot tables.

Requirements

• Fintech/banking/insurance/web3 industry experience (nice to have).
• Experience with processing on-chain data (e.g. using data from Dune, Solscan, etc.).

Benefits

• Individual education budget
• Cool team buildings
• Private health insurance
• Flexible work environment based on trust
• Flexible work time – work when you are most productive, with no micromanagement
