About the role

  • It moves data through LLMs, transforms agent outputs into structured downstream data, runs jobs reliably, and keeps the system fast, cheap, and observable as we scale.
  • This is an in-person role, 5 days a week in our office.

Responsibilities

  • Own the data platform: Maintain and evolve the platform that powers every job across the company.
  • Build agent transformation infrastructure: The systems that take agent outputs and turn them into structured, queryable data downstream.
  • Build observability and tooling so the team can debug and iterate quickly.
  • Partner with AI Engineers: Expose new capabilities through the platform and shape the interfaces they build on.
  • Experience building or maintaining production pipelines that handle non-trivial volume, retries, backfills, and failure recovery
  • Comfort with PostgreSQL at scale: schema design, multi-schema setups, and migrations
  • Maintain and evolve the platform that powers every job across the company.
  • Expose new capabilities through the platform and shape the interfaces they build on.

Requirements

  • The ability to balance reliability with iteration speed is essential.
  • Strong Python engineering experience supporting production systems (FastAPI or similar)
  • Hands-on experience with a data orchestrator (Dagster, Airflow, Prefect, or Temporal) and dbt or similar transformation tooling
  • Comfort with AWS infrastructure (ECS, Lambda, SQS, Step Functions, RDS, S3) and IaC (Terraform / Terragrunt)
  • Familiarity with LLM APIs and the operational realities of LLM-based systems (latency, cost, retries, structured output, failure modes)
  • Requirements need to be locked down before you can move

Nice to have

  • Experience with distributed compute for Python workloads: Anyscale Ray, Dask, or Spark
  • Experience with Polars and Pandas for data processing
  • Familiarity with Datadog for observability, metrics, and tracing
  • Cost optimization experience for LLM workloads
  • Familiarity with pgvector or other vector stores
  • Multi-region AWS deployment experience
  • Some TypeScript/Node experience, since parts of the platform live there
  • We capture observable work data across tools and systems, structure it into a model of how work runs, and use it to measure productivity, check process conformance, and analyze where AI changes the work.

Compensation

  • US$1,000 per month food and commuting allowance
  • US$180,000 to US$250,000
