About Us CareerSwift is an AI-powered career automation platform helping job seekers land their dream roles faster through smart resume building, LinkedIn optimization, interview practice, and now — an agentic infrastructure built on top of LLMs.
We’re expanding our stack beyond the Vercel AI SDK and are looking for someone who deeply understands LangChain, vector databases, and production-level RAG systems to help us scale faster and smarter. What You’ll Work On * Lead the migration of our AI layer from Vercel AI SDK to LangChain (TypeScript). * Design and implement agentic workflows that handle resume optimization, job matching, and auto-apply pipelines. * Build scalable RAG systems for user-specific retrieval and knowledge augmentation. * Integrate Convex or alternative vector databases (Pinecone, Qdrant, Chroma, Weaviate) for efficient embeddings search. * Optimize LLM performance and cost-efficiency, and ensure smooth multi-model support (OpenAI, Anthropic, Gemini). * Collaborate with the core engineering team on Next.js 15 / Vercel / Convex stack. * Optionally, experiment with LangSmith, MCP, and agent orchestration for real-time decision-making.
What We’re Looking For * 3+ years of experience in software engineering (preferably backend or AI systems). * Strong proficiency in TypeScript / Node.js / Next.js. * Proven experience with LangChain, RAG, or vector DBs in production. * Understanding of LLM orchestration, embeddings, and agentic architecture. * Familiarity with OpenAI API, Vercel AI SDK, or similar frameworks. * Ability to architect and optimize pipelines for real-world use cases. * Self-driven, startup-minded, and able to work asynchronously in a small distributed team.
