Job description

About this role

You grow enterprise accounts yourself and you can talk security with the people who run it. Own expansion from day one.

An early-stage AI security startup in San Francisco gives enterprise security and risk teams a full view of what their AI agents rely on. Clients include major US companies in insurance, finance, healthcare and law, and the typical customer grows its spend more than twofold in its first year. Nobody owns that growth full time yet.

That's your job, and it's explicitly not an account-babysitting role.

What you'll own

  • Upsell and expansion across a portfolio of large enterprise customers
  • Demos and trials, run by you
  • Diagnosing product and security problems with the customer
  • Bringing what the product can't solve yet back to the team, so it shapes the roadmap

Must-haves

  • 2+ years of driving upsell and expansion in enterprise accounts yourself (renewals or satisfaction scores alone, or growth someone else closed, don't count)
  • Semi-technical: you can credibly diagnose product and security issues
  • Working from the San Francisco office, 9-9-6
  • Authorised to work in the US without visa sponsorship

Bonus points

  • Experience at a security, devtools or infra company
  • Former founder or early-stage operator
  • A roadmap change that came from customer feedback you brought in

What's in it for you

  • $120k–$150k base
  • A major revenue lever that's entirely yours
  • A small team of engineers, researchers and ex-founders

Good to know

  • Full-time, on-site in San Francisco, 9-9-6
  • No visa sponsorship for this role

Process: conversations with both founders a meeting with the go-to-market team take-home on-site* offer

When you apply, please include

  • Your CV (PDF) and your LinkedIn URL
  • Expansion deals you closed yourself, with the dollar amounts
  • A product you managed, explained at a technical level in a few sentences
  • Your current location, and confirmation that on-site San Francisco works for you
  • Confirmation that you can work in the US without sponsorship
  • Your base salary expectation, your notice period, and any other interview processes you're in

Does this sound like you? Apply now. If you're a match, we'll be in touch within 3 working days.
