About the role

Solutions Engineers own the technical win in the sales process, partnering with AE teams to scope evaluations, design production-ready POCs, and guide customers from prototype to deployment of AI agents. This role is hands-on, highly technical, and customer-facing, with impact measured in closed deals and live deployments.

Responsibilities

  • Own the technical win. Partner with AEs to scope evaluations, run technical discovery, and design POCs that map to the customer's real use case rather than a canned demo
  • Be the technical authority in the room during architecture reviews, security and infrastructure questions, and head-to-head evaluations
  • Co-architect and co-build production AI agents with customer engineering teams, from prototype through rollout
  • Help customers deploy and operate agent-based applications such as conversational agents, research agents, and multi-step workflows
  • Run demos, trainings, and workshops for developer audiences, from single-team sessions to larger technical enablement
  • Advise customers post-sale on architecture, best practices, and roadmap-level decisions, and find the expansion opportunities that come out of those conversations
  • Surface field feedback to product and build reusable POC assets, cookbooks, and example code that scale across accounts
  • Contribute code upstream when it meaningfully improves customer outcomes

Qualifications

  • 6+ years in a relevant technical role such as solutions engineering, sales engineering, customer engineering, software engineering, or founding and product engineering, ideally at a startup or scale-up
  • Comfort owning the technical thread in a sales cycle: discovery, POCs, architecture reviews, and competitive evaluations
  • Ability to explain technical tradeoffs clearly and build trust with developer audiences, then translate that into a decision the customer is ready to make
  • A track record of taking responsibility for outcomes, not just recommendations
  • A bias toward action and a willingness to figure things out as you go
  • Genuine interest in operating AI agents in production, not just building demos
