The Role

We're looking for a Senior Data & Platform Engineer to build the data and core platform and infrastructure layer that powers our AI systems.

  • Design and implement core backend systems and integrations that power the product.
  • Design and build our data platform (orchestration, pipelines, developer workflows)
  • Create scalable systems for data ingestion, transformation, and access
  • Design data models and APIs that won't collapse under growth.
  • Make sane decisions about schemas, indexes, migrations, and performance.
  • Own infrastructure for data + AI workloads (containers, orchestration, cloud services)
  • Enable self-serve data workflows for engineering and product teams
  • Improve observability, reliability, and performance across the data stack
  • Support AI/ML systems (embeddings, vector data, model pipelines)
  • Build tooling for document processing, metadata, and normalization
What We're Looking For
  • 7+ years in data engineering, platform engineering, or backend infrastructure
  • A track record of shipping and owning production systems.
  • Strong systems thinking (not just pipelines - platform mindset)
    • Backend system design and API design
    • Data modeling and relational databases
    • Performance, reliability, and failure modes
  • Proficiency in Golang, SQL, Terraform, AWS
  • Comfort in a fast-moving startup environment
Bonus
  • LLMs / RAG, vector search, fintech or regulated systems
  • Have startup or early-stage experience.
Why Join
  • Build the foundation layer of an AI-native product
  • High ownership + direct impact
  • Work where data, platform, and AI converge
The Fit

You're someone who doesn't just move data - you build the systems that make data usable at scale.
