• Integrate third-party platforms (e.g., Google Calendar, Instantly, CRM tools)

• Collaborate with designers and stakeholders to deliver polished UI/UX using TailwindCSS and shadcn/ui

• Write clean, maintainable, and well-structured code following team standards

• Optimize performance across frontend and backend for speed and scalability

• Participate in code reviews and contribute to a high-trust engineering culture

• Support deployment, debugging, and monitoring on platforms like Vercel and Cloudflare

Requirements

• 2–4+ years of experience building full-stack applications with Next.js

• Strong experience with App Router, server components, and modern data-fetching patterns

• Proven experience integrating LLMs into production systems

• Hands-on experience building RAG applications, including:

  • Data ingestion and chunking

  • Embedding generation

  • Vector databases (e.g., Pinecone, Weaviate, Supabase)

  • Retrieval and prompt engineering

• Experience designing multi-step AI workflows or agent-based systems

• Solid understanding of REST APIs and third-party integrations

• Ability to own features end-to-end with minimal supervision

• Strong communication skills and a collaborative mindset

Nice to Have

• Experience with Hono.js or edge runtimes

• Familiarity with AI SDKs, tool usage, or function calling

• Knowledge of hybrid search, re-ranking, or advanced retrieval techniques

• Experience working in early-stage or greenfield environments

• Basic DevOps experience (CI/CD, logging, monitoring)

What We Value

• Ownership and accountability

• Clear, readable code

• Curiosity and willingness to experiment with AI

• Balancing speed with reliability

• Thoughtful collaboration and constructive feedback

What You’ll Work On

• SaaS features like onboarding, dashboards, and settings
