Assembled helps companies scale customer support operations by providing AI agents and workforce management software. This is the founding Head of Sales Engineering role—you'll own the technical side of deal execution and build the sales engineering function from the ground up.
You'll start hands-on, running technical evaluations and proof-of-concepts on Assembled's most strategic deals, especially early on. You'll demonstrate how AI agents for chat, voice, and email resolve real customer issues within existing support stacks and work alongside human teams. As the team grows, you'll hire and develop sales engineers, define team metrics (technical win rate, POC conversion, time-to-value), and establish the foundations: demo environments, discovery frameworks, POC playbooks, and reusable technical content.
Key responsibilities include leading technical evaluations from discovery through close; owning RFP and security assessment responses; acting as the bridge between prospects and product to shape roadmap decisions; and partnering with sales leadership to identify patterns in wins and stalls. You'll carry a reduced quota to stay deeply involved in deal execution while building a high-performing function.
Assembled serves 400+ customers including DoorDash, Salesforce, Stripe, and Sephora. The company has raised $71M from NEA, Emergence Capital, Stripe, and Basis Set Ventures, with offices in San Francisco, New York, and London. The role requires in-person presence 5 days per week from the San Francisco office (Mission) or New York (Chelsea Market).
REQUIREMENTS:
- Proven track record closing large enterprise deals ($500K+ upfront value) — this is a hard requirement
- 5+ years in sales engineering, solutions consulting, or comparable technical pre-sales role (preferred)
- Experience building or scaling a sales engineering team from scratch, ideally more than once
- Strong analytical skills and ability to reason across complex, wide product suites
- Hands-on experience selling or deploying AI agents across chat, voice, or email (strong plus)
- Background in Workforce Management or Support Operations (strong plus)
- Ability to manage and mentor sales engineers while remaining hands-on and carrying a quota
- Comfort with C-level executives, engineers, and support agents alike
- Ability to move fast, work independently, and push through roadblocks in unstructured environments
