Product Engineer (Frontend)

You are a T-shaped product engineer with a spike in frontend engineering. You will work closely with the product and engineering team to build user-facing features, ship at pace, and support the existing infrastructure as we scale. You do not need to be a design expert, but strong UI/UX sensibilities and attention to detail are valuable.

You take initiative, adapt quickly, and communicate clearly. The team is small and fast-moving, so you'll be expected to make decisions and ship code autonomously. You will help the company grow from $3M to $30M ARR, owning projects end-to-end—from ideation to deployment—while helping shape how we build products and infrastructure at Kernel.

What You'll Be Doing

• Designing and developing product features that directly impact user workflows
• Collaborating with design, product, and other engineers to deliver exceptional user experiences
• Writing and maintaining clean, reliable, and scalable code across the stack
• Helping ensure performance and reliability for large-scale data operations
• Automating workflows to improve developer velocity and reduce manual work
• Supporting integrations with CRMs and third-party APIs
• Participating in roadmap discussions and contributing technical insights

What You Bring

• 6+ years of software or product engineering experience
• Strong experience building and scaling production systems
• Expert with frontend engineering (NextJS, React, TypeScript)
• You have a good eye for design and good at bringing complex interfaces to life
• Strong understanding of LLM application development patterns (RAG, prompt engineering, consistency testing) - either through production experience or demonstrated personal projects. If you're new to LLMs but have shipped complex production systems in other domains and are comfortable rapidly learning new technologies, we'd still love to hear from you.
• Ability to operate autonomously in a small, high-velocity team
• Excellent communication and collaboration skills
• Strong experience with modern frontend tooling or performance optimization

It is a plus if you also have:

• Experience working on AI-driven or data-heavy products
• Backend experience (NodeJS, Postgres, TypeScript)
• Understanding of CRM data models or workflow automation
