Customer Support Analyst

As a Customer Support Analyst at Allium, you troubleshoot complex technical issues for institutional customers relying on Allium's canonical blockchain data layer. You work at the intersection of data infrastructure, blockchain mechanics, and enterprise support, resolving issues that span SQL queries, data pipelines, API integrations, and on-chain data interpretation across 140+ blockchains.

What you'll do

• Troubleshoot and resolve complex customer issues involving SQL queries, data pipelines, API integrations, and other Allium integrations such as Kafka
• Map customer issues to solutions within Allium, whether in a table in the dataset, an alternative delivery mechanism, relevant documentation, or an integration pattern
• Help customers diagnose problems in their data sources such as Snowflake, BigQuery, and Postgres, and optimize performance
• Collaborate with engineering to investigate bugs, identify patterns, and ship fixes
• Develop internal tools and scripts to automate troubleshooting and improve customer response times
• Write clear documentation and knowledge base articles for customers and internal teams
• Partner with GTM and product teams to translate customer pain points into actionable insights
• Participate in daily syncs to discuss ongoing issues, progress, and improvements
• Synthesize support work into an AI-native system that builds leverage
• Triage and prioritize incoming issues against customer SLAs, distinguishing a P1 data incident for an institutional customer from a routine query question and sequencing work so the highest-impact problems get resolved first

• Experience providing technical support for a SaaS or data product
