Staff Software Engineer

Role Description

If you want to own the data infrastructure that powers real-time pricing decisions for thousands of hotels worldwide — and you're energised by the idea of doing it in an engineering culture where AI isn't a future ambition but how work actually gets done today — this is the role. You'll be the technical authority on Duetto's data lakehouse, driving everything from pipeline architecture and data quality to the shift from batch to near-real-time streaming.

What You'll Be Doing

• Own the design, performance, and reliability of Duetto's data lakehouse.
• Evolve the Python/PySpark pipeline framework across a bronze → silver → gold architecture on AWS, including:
  • Glue jobs
  • Iceberg MERGE operations
  • Schema evolution
  • Partitioning strategies
• Architect the shift from batch to near-real-time streaming, building SQS-driven stream pipelines with Iceberg sinks.
• Expand ingestion, normalisation, and analytics layers across the full lakehouse.
• Drive data quality and governance at scale by:
  • Extending the Great Expectations framework
  • Leading adoption of data contracts to formalise schemas between producers and consumers
  • Owning the Athena SQL layer that analysts and product teams depend on
• Strengthen observability and reliability through Datadog, Sentry, and Sumo Logic.
• Optimise Glue job performance, including:
  • Worker sizing
  • DPU allocation
  • Spark tuning
  • Cost management
• Build and maintain shared internal Python libraries published to JFrog.
• Drive improvements to GitHub Actions, Docker-based testing, and CI/CD deployment workflows.
• Work AI-first every day, using Claude Code and MCP tools in your regular workflow.
• Contribute to AI-assisted pipeline generation, schema inference, and automated data quality alongside a custom multi-agent system with 17 specialised agents.

Qualifications

• 7+ years building production data systems in Python.
• Deep expertise in PySpark and distributed data processing — Glue, EMR, or Databricks.
• Strong experience with lakehouse architectures: Iceberg, Delta Lake, or Hudi on S3.
• Production experience with Airflow or a comparable workflow orchestrator.
• Solid AWS production experience across S3, Glue, Athena, Lambda, and SQS.
• A track record of improving data quality, governance, and pipeline reliability at scale.

Requirements

• Working knowledge of Java for reading upstream systems.
• Experience with Trino or Presto for interactive SQL analytics at scale.
• Experience with dbt for data transformation and modelling.
• Familiarity with Great Expectations or similar data quality frameworks.
• Genuine interest in AI-assisted development and LLM-based tooling.
• Familiarity with hospitality data — reservations, rates, inventory, demand signals.

Benefits

• AI-first is not a marketing line here; every engineer uses Claude Code and a custom multi-agent system daily.
• Contribute to AI-assisted pipeline generation and work alongside 17 specialised agents with human-in-the-loop approval gates.
• Engage with real technical challenges, processing millions of rate decisions daily.
• Own something meaningful with true technical authority over the lakehouse that powers every pricing decision, forecast, and report.
• Join a team with low ego, high EQ, genuine intellectual curiosity, and active mentorship across a collaborative US and Europe team.
• Work with a modern stack including Python/PySpark, Apache Iceberg, Airflow, AWS Glue, SageMaker, and Terraform.
