Sales Engineer, AI Infrastructure (SF) at lavendo.com in San Francisco

Job description

• Application
• Lavendo partners with startups and high‑growth companies to help them hire top‑tier sales, GTM, and technical talent. This role is with one of our clients; we’ll share full details about the company and interview process as we get to know you and confirm mutual fit.
• They believe developers and AI agents shouldn't have to fight the web to get data out of it. Every hour spent maintaining a scraper or babysitting a parser is an hour taken away from the actual product. Their job is to make that problem disappear.
• As a Sales Engineer, you'll own the technical side of every serious deal: discovery, architecture, demo, POC, start to finish. You'll sit close to the VPs and the founders, so the feedback loop between "customer needs this" and "we're building it" is short. The split runs roughly half pre-sales, half implementation. You see a deal through from the first call to production.
• The people who do well here build things themselves. They get more energy from a good customer conversation than from a status meeting, and they're comfortable owning an outcome without a playbook to follow.

Responsibilities

• Run the full technical sales cycle: discovery, solution architecture, live demos, POCs
• Get in front of customers and show them, hands-on, how the product solves their problem
• Build POCs and technical proposals strong enough to turn "interesting" into "signed"
• Answer the hard technical questions that decide deals, and know when to pull in engineering
• Take what you hear from prospects straight back to product and engineering
• Split your time close to 50/50 between pre-sales and implementation
• Report to the VP of Revenue and Success, with real access to the founders

Requirements

• 3-7 years in pre-sales engineering or solutions engineering at a dev tools, API, or data infra company, as an individual contributor
• Built and delivered POCs for enterprise prospects on your own
• Hands-on experience building with LLMs, RAG, agents, or AI data pipelines. You can read code, write, and use an API without help
• Can talk to an engineer about architecture and to a VP about ROI in the same afternoon
• Genuine energy for customer conversations, with real ownership over deal outcomes
• Authorized to work in the US already (no visa sponsorship on this one, so US citizens or Green Card holders)
