About the role

Join our team to disrupt how products are built 🚀

Product development is broken: dev teams rush to build, while valuable user feedback gets lost in the shuffle of App Store reviews, support tickets, user interviews, and sales calls.

Kraftful copilot amplifies user voices, turning overlooked feedback into actionable insights and transforming frustrated users into an engaged community that rallies behind your product.

Since our launch last year, we’ve been on a crazy ride:

  • Tens of thousands of product builders have embraced Kraftful
  • Innovators at top tech companies like Meta, Google, Netflix, and more rely on us
  • Global brands, car manufacturers, public agencies, financial institutions, and even cities trust our solution
  • The feedback from Kraftful users is that our product is a “game-changer”

To fuel our growth, we’re looking for passionate engineers ready to make an impact.

This isn’t just another job - it’s an opportunity to be a founding member of a rocketship poised to redefine the future of product development.

Responsibilities:

  • Design, develop, test, and support features for our web and backend applications
  • Work with the latest large language models (LLMs) from OpenAI
  • Adopt or invent tools to help scale our engineering efforts
  • Tackle various challenges that arise in an early-stage startup with a can-do attitude
  • Review code developed by other developers and provide feedback to ensure best practices
  • Debug and triage product bugs for our users by understanding the source of the issue and impact on our business
  • Collaborate closely with the team to share ideas on how Kraftful can be successful
  • Take ownership of projects from concept to production, ensuring high quality and timely delivery
  • Contribute to the technical vision and help shape the product direction as part of the core team

Requirements:

  • BA/BS degree (or equivalent)
  • 6+ years of experience building production software in a team environment
  • Excellent interpersonal skills, including writing, speaking, and listening
  • Fearlessness in taking on new challenges with potentially unclear solutions
  • Commitment to delighting customers
  • Flexibility in a constantly changing environment
  • Curiosity to become an expert in the rapidly evolving world of LLMs

Our tech stack:

  • React
  • Tailwind
  • PostgreSQL and Prisma
  • LLM (OpenAI)
  • BullMQ
  • Redis

Kraftful is backed by Y Combinator, Precursor Ventures, F7 Ventures, Leadout Capital, Google, Samsung Next, Lukas Biewald (Founder/CEO Weights & Biases), Manu Sharma (Founder/CEO LabelBox), and other top investors.

About Kraftful

At Kraftful, we're building the copilot for product teams. Our mission is to help product builders leverage LLMs to listen to users at scale and actively involve them in the dev process.

As one of the inaugural alpha users of GPT-3, we built first prototype of Kraftful copilot in early 2020. As LLMs advanced, we launched our first GPT-powered feature in 2021 and ultimately pivoted our company to a complete LLM solution for product builders in 2023, seeing incredible traction.

We’re a team that puts users first. We make hard, pragmatic decisions. Constant iteration is at the core of our product and company. Empathy is our superpower.
