ABOUT AVANTOS

Avantos is building the AI-native operating system for financial services — transforming fragmented data into a single, intelligent system that powers workflows, automation, and decision-making.

We’re a product-led, fast-moving team at the intersection of AI, fintech, and modern infrastructure.

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.

This is not just about pipelines — it’s about creating the systems, tooling, and abstractions that enable engineers and AI workflows to move fast, safely, and reliably.

WHAT YOU’LL DO

  • 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.
