Why Apply
Massive Opportunity: Forbes reported that we could be YC's fastest unicorn, reportedly raising at a $3.2 billion valuation, and we're not slowing down.
Founding Impact: You will own and architect core infrastructure systems that power our platform from the ground up.
Equity & Growth: Competitive salary and meaningful equity. As we scale, you’ll have the opportunity to shape the engineering organization and lead major technical initiatives.
Strong Team: Our founding team has experience from Citadel Securities, Meta, Google, Silver Lake, and Morgan Stanley - work alongside world-class engineers and researchers.
Overview
Growth Engineering is where engineering meets the company’s most important commercial and user-facing problems. You will build the product systems that help us find, qualify, activate, and retain exceptional experts - and help the teams serving frontier AI labs move faster with better information and less manual work.
This is a hands-on product engineering role for someone with 3-5 years of experience who wants unusually high ownership. You will work directly with Growth, Operations, Design, and the founders, turning ambiguous opportunities into simple, reliable software that drives measurable outcomes.
Responsibilities
- Build end-to-end product experiences across expert acquisition, onboarding, assessments, matching, activation, and retention.
- Partner directly with Growth and Operations to identify the highest-leverage bottlenecks, instrument the funnel, and ship improvements quickly.
- Own experiments from idea through implementation and measurement: define the hypothesis, build the product, assess the result, and iterate.
- Develop internal tools and automation that make customer-facing and operational teams dramatically more effective without compromising quality or control.
- Create durable product primitives and clean interfaces rather than one-off workflows; improve existing systems as you touch them.
- Use data, user feedback, and technical judgment to make clear tradeoffs between speed, reliability, and long-term maintainability.
Required Qualifications
- 3-5 of professional software engineering experience, ideally building high-velocity product, growth, marketplace, or workflow software.
- Strong full-stack engineering ability and a track record of shipping user-facing product from ambiguous requirements.
- Excellent product sense: you can distinguish the real problem from the first requested solution and focus on what will move the metric.
- Comfort working closely with non-technical partners and translating their needs into simple, robust systems.
- High ownership, strong judgment, and the ability to move quickly without creating unnecessary complexity.
Preferred Qualifications
- Experience with growth engineering, marketplace liquidity, onboarding, conversion optimization, or product analytics.
- Experience at a fast-growing startup or on a lean team where engineers owned both product decisions and execution.
- Interest in AI, data products, or tools that make complex work more scalable.
Company Benefits (For Eligible Employees)
- Health Insurance: Medical, Vision, Dental
- 401(k) with Employer Match
- Daily Meals: Daily UberEats Stipend
- Monthly Wellness Stipend
