At Capalo AI, we build software that accelerates the transition to renewable energy. Our AI-powered platform, Capalo Zeus VPP™, optimizes large-scale battery energy storage systems and distributed energy resources across European electricity markets. As a certified Balance Responsible Party (BRP), we operate the full stack, from market prequalification and automated trading to real-time dispatch and regulatory compliance.

ROLE MISSION

As a Data Engineer, you’ll own the data infrastructure that powers our AI models, trading systems, and customer-facing products. This is a production-critical role: when electricity markets are live, our data pipelines must be reliable, observable, and scalable.

WHAT YOU'LL DO

• Build and own production data pipelines for time-series energy market data, battery telemetry, weather feeds, and trading signals

• Handle incremental loads, historical backfills, and data quality validation

• Design and maintain data APIs for real-time and historical data (versioning, authentication, pagination, SLAs)

• 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
