Senior Full-Stack Engineer (Founding Team)

About Seeko

Seeko is an AI-native sales training platform helping sales teams at technical product companies master product knowledge. We transform dense documentation into engaging learning experiences — AI-generated podcasts, interactive quizzes, and roleplay coaching. Think "NotebookLM for sales teams."

We're venture-backed and working with design partners including companies in the dev tools and healthtech spaces.

The Role

We're looking for a senior full-stack engineer to join as a founding team member. This isn't a "ticket executor" role — you'll own technical direction, shape architecture decisions, and ship features end-to-end. You'll work directly with the CEO (technical background) and collaborate closely with the product team.

Type: Contract-to-hire

What You'll Work On

• Core product features — content generation, podcast creation, quiz/assessment flows, roleplay functionality
• AI integrations — working with Gemini, Claude, OpenAI, and Cartesia (voice) APIs
• Full-stack ownership — frontend UI, backend APIs, database schema, deployment
• Foundational architecture — your decisions will shape how this system scales

Tech Stack

• Frontend: React 18, Vite, TypeScript, TanStack Query, ShadcnUI, Tailwind
• Backend: Node.js, Hono, tRPC, TypeScript
• Data: PostgreSQL (Prisma + pgvector), Redis, BullMQ
• AI: Gemini, OpenAI, Anthropic Claude, Perplexity, Cartesia
• Infra: AWS, Turborepo monorepo, WorkOS (auth)

What We're Looking For

Must have:

• 5+ years building production web applications
• Strong TypeScript and Node.js experience
• Comfortable across the full stack (React + backend APIs + databases)
• Experience with or strong interest in LLM APIs
• Self-directed — you'll have real ownership, not hand-holding

Nice to have:

• Startup experience
• Experience with monorepos, tRPC, or Prisma
• Built AI/LLM-powered products before

Mindset:

• Ownership mentality — you see a problem, you fix it
• Bias toward shipping — perfect is the enemy of good
• Clear communicator — remote and async-friendly
• Hungry — this is a founding team role, not a 9-5

Why Join

• Founding team equity — meaningful stake, not token options
• Real ownership — shape the product and architecture
• Tight feedback loops — working directly with customers, you'll see impact fast
• AI-native product — if you're excited about LLMs, you'll be in your element
