Your mission

You'll be responsible for the technical backbone of our product—shaping architecture decisions, evolving production systems, and setting the engineering standard as our team grows:

  • Define and evolve our backend architecture—making strategic decisions on service boundaries, data flows, and scaling patterns.
  • Design and build high-throughput content ingestion and transformation pipelines that reliably process thousands of articles daily.
  • Own the full lifecycle of our core API services (FastAPI)—from design through deployment to operational excellence.
  • Establish backend engineering standards: code quality, testing strategies, documentation practices, and review processes.
  • Drive infrastructure decisions—evaluate trade-offs between cloud services, optimize costs, and ensure our systems are observable and resilient.
  • Mentor and guide future engineering hires as the team scales.
