Job description

About Us
At Union, we are solving one of the hardest challenges in AI infrastructure today: enabling high-velocity iteration while maintaining seamless production-readiness for AI workloads at scale.
Flyte, the open-source project we steward, has emerged as the modern standard for data and AI orchestration, and is trusted by leading technology organizations including LinkedIn, Stripe, and Wayve to run millions of mission-critical workflows on the platform. These workflows comprise data preparation, model training, and scaled inference spanning thousands of GPUs, all major clouds, and on-premise infrastructure.
We have a technical founding team who created Flyte while at Lyft, a deep bench of infrastructure experts from top companies, and have raised from top investors like NEA and Nava Ventures.
The Opportunity - North America
Reporting our Head of Sales Engineer, we are hiring a Sales Engineer to support our sales team with our ambitious revenue growth goals as we continue to onboard new customers to Union.

  • Drive adoption of Union by leveraging hands-on experience in building demonstrable use cases, troubleshooting workflows, and showcasing platform value to prospective customers.
  • Own the technical success of a trial by delivering on prospects' success criteria. Connect the dots between business value and technical outcomes.
  • Engage at all levels of technical stakeholders to drive technical debates and design choices with our mid-market and enterprise customers.
  • Contribute to the technical qualification of an opportunity through paring technical needs to key features and formulate unique selling propositions displacing competition.
  • Develop and advise prospects on representative demonstrable examples, reference architectures and best practices for optimal design, integration and operation of Union.
  • Actively support Union users with trials and production deployments by onboarding users and workflows, debugging problems related to infrastructure, platform or code in customers' integrated end-to-end solution.
  • Represent the product at field events such as conferences, seminars, etc.

  • Working knowledge by applying popular machine learning frameworks (Pytorch, Tensorflow, etc) and data processing frameworks (Spark, Flink, Beam etc) to building production grade AI pipelines.
  • General understanding and working knowledge of distributed systems at scale and familiarity with cloud platforms (AWS, GCP, Azure), Infrastructure as Code (Terraform, Cloudformation), Containers (Docker), Kubernetes and CI/CD systems.
  • Highly organized and thrive in a high-volume environment that will naturally have ambiguities and competing priorities
  • Possess working knowledge of sales frameworks such as MEDDIC
  • It's a strong plus if you have been a part of or contributed to the Flyte or Union communities
  • Able to travel to conferences or customer locations with minimal restrictions and occasionally on short notice.
