AI/ML Engineer

Company Description

$10M Seed consumer AI dating startup backed by Forerunner Ventures, NFX, and Pear VC

Job Description

You will own the matchmaking and recommendation systems for a voice-first AI dating app where 80% of introductions lead to real-world dates. As an early engineer, you'll transition these core algorithms from zero to production scale, working alongside a founding team with deep experience from Uber, Cash App, and Faire.

Location: San Francisco, USA

Why This Role Is Remarkable

• High-impact ownership of the core product value where your models directly drive user connection without swiping or endless feeds.
• Exceptional pedigree and backing from top-tier firms like Forerunner, NFX, and Pear VC in a $10M seed round.
• Strong early traction with users spending 27 minutes on average talking to the AI, creating a rich signal for matchmaking.

What You Will Do

• Design and implement the primary matchmaking and ranking algorithms that power the 1-to-1 daily introduction experience.
• Scale experimental recommendation systems into high-availability production environments to support a rapidly growing user base.
• Lead and grow a small technical team, establishing the engineering culture for the ML and personalization org.

The Ideal Candidate

• Proven experience building and scaling user-facing recommendation or ranking systems at a consumer-growth company like Tinder, Instagram, or Spotify.
• Early-stage veteran who joined during a 0→1 phase and stayed long enough to see their systems scale in production.
• Direct track record of creating models that impact user-facing product surfaces rather than internal tools, fraud, or ad-tech.

We Never Post Fake Jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
