• Design data models for analytical and operational workloads across AWS (Glue, Athena, Timestream, Lambda)
• Implement monitoring, dashboards, and alerts using Grafana and AWS CloudWatch
• Own data reliability: runbooks, data quality checks, incident response, and resilience improvements
• Collaborate with ML, backend, and product teams on data requirements and schema design
• Write clean, tested code; participate in reviews; document and own systems in production

WHAT WE’RE LOOKING FOR

Must-haves

• Strong Git, Python and SQL; experience building production ETL/ELT pipelines
• Hands-on AWS data stack experience (Glue, Athena, Lambda, Timestream or similar)
• Experience operating production data pipelines with backfills and failure recovery
• Experience designing and operating data APIs
• Observability mindset (monitoring, alerting, dashboards; Grafana a plus)
• Solid software engineering practices (CI/CD, testing, code reviews, documentation)

Nice-to-haves

• Energy markets, trading systems, or mission-critical data platforms

WHY JOIN CAPALO AI?

• Meaningful Impact: Your work directly facilitates the transition to renewable energy and helps lower carbon emissions globally.
• Cutting-Edge Tech: Work at the intersection of AI, cloud infrastructure, and the physical energy grid.
• Growth & Ownership: As an early member of a scaling team, you’ll have significant influence over our technical direction and culture.
