You’ll lead the evolution of ingestion, orchestration, and customer-facing APIs, transforming data into a reliable product capability for top tier investment banks and asset managers globally.

Location: London, UK

What you will do:

• Own the production data platform architecture across AWS and GCP, ensuring operational reliability and industrializing customer-facing data feeds.
• Define the data engineering operating model, setting standards for ingestion, CI/CD guardrails, and schema contracts to accelerate product delivery.
• Act as a hands-on player-coach, spending 75% of your time building and 25% mentoring talent to reduce key-person dependency.

The ideal candidate:

• Proven experience building and scaling production-grade data platforms using Python, SQL, and orchestration tools like Dagster or Airflow.
• Strong track record of converting technical infrastructure improvements into measurable business outcomes like improved reliability and faster source onboarding.

We never post fake jobs

This isn’t a trick. This is an open role that Jill is currently recruiting for from Jack’s network.

Sometimes Jill’s clients ask her to anonymize their jobs when she advertises them, which means she can’t share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn’t much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we’re giving his services away for free.
