About the Role — Product Engineer (New Product, First Owner):
We are looking for a pioneering engineer to spearhead our new product line. This role offers a high degree of autonomy and ownership for individuals who are builders, innovators, and entrepreneurial in spirit.
You will be responsible for the entire product lifecycle from inception to launch, including discovery, prototyping, development, and continuous improvement. The product will serve as a user-friendly interface on top of our robust data infrastructure, allowing non-technical users (HR, Sales, Operations) to generate AI agents via natural language prompts.

Key Responsibilities:
- Lead the development of a new product utilizing fuku's APIs.
- Create core algorithms for AI agents based on natural language inputs.
- Manage product strategy and execution: user discovery, scoping, rapid prototyping, shipping, iteration, and metrics analysis.
- Collaborate closely with Sales and Customer Success teams to identify critical workflows.
- Develop production-quality user experiences (fast, simple, accurate).
- Partner with the Head of Engineering to address architecture, reliability, and data/privacy considerations.

Requirements:
- 5+ years of experience delivering production-grade software.
- Strong foundation in full-stack engineering.
- Demonstrated experience in 0→1 product development.
- Familiarity with sales and go-to-market strategies.
- Proficiency in designing and implementing core algorithms, AI workflows, and natural language interfaces.
- Availability to work on-site in San Francisco for prototyping (visa sponsorship available).
- Previous startup experience (Series A/B+ preferred).

Preferred Qualifications:
- Experience in growth engineering at leading firms (e.g., Ramp, Brex, Rippling, Workato).
- Background as a founder or early-stage builder, especially in sales tools, workflow automation, or data APIs.
- Strong computer science fundamentals — graduates from IIT/IIIT/DTU or top-tier institutions are encouraged to apply.
