About the role

Embedded engineer who sits inside customer stacks to deploy Fastino models in production, owning technical delivery from first call to go-live and turning field work into reusable tools.

Responsibilities

  • Embed with customer engineering teams to scope, build, and deploy Fastino models into their production systems.
  • Write real code: integrations, data pipelines, eval harnesses, and services that run on customer infra (cloud, VPC, on prem).
  • Fine-tune and evaluate models on customer data, and prove they beat the baseline on accuracy, latency, and cost.
  • Debug the messy stuff: auth, networking, GPU and inference performance, data quality, weird edge cases.
  • Own the technical side of deals from first call through go-live, working closely with our founders and AEs.
  • Turn what you build in the field into reusable tools, reference architectures, and SDK improvements.
  • Bring customer feedback straight to research and product, and push for what customers actually need.

Qualifications

  • BS or MS in Computer Science or a related field (or equivalent experience).
  • 3+ years as a software engineer, ideally with some time in a customer facing role (FDE, solutions engineering, consulting, or similar).
  • Strong in Python. Comfortable with at least one of TypeScript, Go, or Rust.
  • Hands on experience shipping LLM or ML systems to production: APIs, fine-tuning, evals, RAG, or agents.
  • Solid with cloud and infra basics: AWS/GCP/Azure, Docker, Kubernetes, networking, and security.
  • Clear communicator who can explain tradeoffs to an engineer and a VP in the same meeting.
  • Ownership mindset. You'd rather fix it yourself than file a ticket.
  • Bonus: experience with GLiNER, NER, or other information extraction models.
  • Bonus: early stage startup experience.
  • Willing to travel to customer sites as needed.
