Senior Software Engineer, Cloud (Poland)

Redpanda is the first runtime and control plane for agent-data interaction — a unified platform that combines streaming, SQL analytics, and intelligent connectivity with the governance layer enterprise AI agents need in production. Built on infrastructure already trusted by Fortune 500 companies and fast-growing startups, Redpanda enforces governance entirely outside the agent's data path, controlling what agents see, limiting what they do, and capturing a tamper-proof record of everything they touch, so organizations never have to choose between innovation and control. About the Role: We're looking for an experienced senior software engineer to drive Redpanda Cloud's billing and payments services and workflows end-to-end, as part of a new Warsaw-based team. You'll take ownership of usage-based billing via Metronome, and credit-card management via Stripe, coming up to speed with our current implementation, stabilising it, and then driving the roadmap to keep metering, invoicing, and payments accurate, transparent, and trustworthy as we expand our products and services with the Agentic Data Plane. You'll partner closely with finance, product, and the wider engineering team across the wider customer-experience journey. This is a hybrid role based in our Warsaw office. The Team You'll join a newly-formed small, cross-functional Cloud team based in our new Warsaw office that owns the services powering the customer-facing journeys at the heart of Redpanda Cloud.
