Full Job Description

📋 Description

  • As a Product Engineer (Frontend) at Kernel Medical Devices, Inc., you will play a pivotal role in building user-facing features that power AI-driven company data solutions for enterprise RevOps teams, directly impacting how customers interact with CRM-integrated intelligence at scale.
  • You will design and develop product features, collaborate with design and engineering teams to deliver exceptional user experiences, write and maintain clean, scalable code across the stack, support CRM and third-party API integrations, automate workflows to boost developer velocity, and contribute to technical roadmap discussions while helping scale the platform from $3M to $30M ARR.
  • Kernel is a fast-growing, AI-native startup backed by $14M in Series A funding, processing ~30B tokens daily with a minimalist architecture (one database, one queue) to deliver scalable entity and hierarchy data to clients like Navan, Gong, Mistral, and AlphaSense. The engineering team is small, high-impact, and values autonomy, initiative, and technical excellence.
  • You will gain end-to-end ownership of product features, deepen your expertise in frontend systems and LLM-integrated applications, shape frontend architecture and performance practices, and grow alongside the company by working closely with founders and senior engineers in a high-velocity, innovative environment.
