Support Engineer

As a Support Engineer at Allium, you help institutional customers and engineers resolve complex issues with onchain financial data. You troubleshoot SQL queries, data pipelines, API integrations, and Allium's products, mapping customer problems to solutions across a petabyte-scale data infrastructure serving 140+ blockchains. You work closely with engineering to identify bugs, develop automation tooling, and synthesize support into an AI-native system that scales.

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 a table in the dataset, another delivery mechanism, relevant documentation, or an integration pattern such as push versus pull
• Help customers diagnose problems in their data sources (Snowflake, BigQuery, Postgres, etc.) 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
• 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 to resolve the highest-impact problems first
• Synthesize all of the above into an AI-native support system that builds leverage

What you bring

• Fluency in AI tools, common failure modes, and modern practices
• Fluency in SQL: you can confidently write, optimize, and debug complex queries
• Experience providing technical support for a SaaS or data product
• A working knowledge of blockchain data primitives across ecosystems like Solana and EVM chains
• Familiarity with APIs, data connectors, and ETL tools
• Comfort with scripting or automation in Python, Bash, or similar languages
• Strong understanding of Linux environments and command-line tools
• Excellent communication and documentation skills: you can explain complex concepts simply
• A proactive, empathetic approach to customer relationships
• The ability to work independently and take full ownership of issues from report to resolution

Nice to have

• Experience with data warehouses such as Snowflake, BigQuery, or Redshift, or BI tools
• Exposure to infrastructure-as-code tools such as Terraform or Ansible
• Experience debugging API or integration issues across cloud environments
• Familiarity with data modeling or transformation frameworks such as dbt or Airbyte
• Experience with message queues and event buses such as Google Pubsub or Kafka

What we offer

• Medical, dental, vision, life, and AD&D insurance. US employees receive 100% coverage for Gold plans and 80% for dependents
