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.
Tech Stack You’ll Touch
Next.js 15 · TypeScript · LangChain · Convex · Vercel AI SDK · OpenAI API · PostHog · Stripe · Vector Databases (Pinecone / Qdrant)
Bonus Points
* Experience with LangSmith or LangServe.
* Understanding of RAG evaluation, embeddings optimization, and multi-agent flows.
* Interest in AI products, SaaS, or career automation tools.
Why Join
You’ll be part of a fast-growing startup where decisions are fast, ideas matter, and your code directly impacts thousands of job seekers worldwide.
* lease, add your salary expectations to your application.
