About the Role
We are seeking a Full-Stack AI Engineer to accelerate development of intelligent, AI-native features across our platform. You will work across the full stack, from UI to backend services, with a strong emphasis on integrating and building with large language models (LLMs) and AI APIs.

This is a fast-paced, high-impact engagement. The position is open and should be filled as soon as possible. Candidates who can contribute immediately are strongly preferred.

Responsibilities

  • Develop and ship full-stack features across Angular (frontend) and Node.js / NestJS (backend)
  • Integrate LLM APIs (Claude, OpenAI, or equivalent) into product workflows
  • Build and maintain AI agent pipelines, prompt chains, and RAG (Retrieval-Augmented Generation) systems
  • Implement streaming, real-time, and async AI response patterns in the UI
  • Write clean, tested, production-quality code in TypeScript or Python
  • Collaborate with product and design teams to define and iterate on AI-powered UX
  • Contribute to code reviews, architecture discussions, and technical documentation

Required Qualifications

  • 5+ years of full-stack software engineering experience
  • Strong proficiency in TypeScript or Python (both frontend and backend)
  • Experience with Angular or a comparable modern frontend framework (React, Vue)
  • Backend experience with Node.js, NestJS, or equivalent
  • Hands-on experience integrating LLM APIs (OpenAI, Anthropic Claude, etc.)
  • Understanding of prompt engineering, context management, and LLM limitations
  • Familiarity with REST APIs, WebSockets, and event-driven architectures

Preferred Qualifications

  • Experience building AI agent systems or multi-step LLM workflows
  • Familiarity with RAG pipelines and vector databases (Pinecone, pgvector, Weaviate)
  • Experience with the Anthropic Claude API or Claude Agent SDK
  • Background in HR tech, payroll, or enterprise SaaS
  • Experience with Nx monorepo tooling
  • Contributions to open-source AI tooling or projects

Tech Stack Highlights
TypeScript or Python, Angular, Node.js, NestJS, Claude API, OpenAI API, RAG / Vector DBs, LLM Agent Pipelines, WebSockets, REST APIs, Nx Monorepo

Target start: ASAP
