Job description

Techmunity are hiring multiple Senior Full Stack Engineers for a VC-backed AI company building the operating system of autonomous agents for commerce - the intelligence layer powering how global brands interact with their customers through AI.

Already running millions of AI-powered customer conversations and transactions, the platform generates ~$4.1M ARR with 170% YoY growth, backed by LVMH's Aglaé Ventures, Sierra Ventures, and Village Global - investors behind Airbnb, Slack, and Spotify.

You'll be joining a high performing 15-person engineering team, who've built an operating system of AI agents that reason, retrieve, and act autonomously across every touchpoint - shopping, support, voice, reviews, and social. These agents manage context, memory, and evaluation in real time, transforming how brands engage customers at scale. What you'll do

  • Ship end-to-end product features across frontend, backend, and infrastructure.
  • Build and scale AI-agent systems that combine LLM reasoning, retrieval, and tool orchestration with enterprise reliability.
  • Design event-driven microservices, RAG pipelines, and observability layers that keep the system explainable and fast.
  • Work closely with Product and Design to turn ambiguous ideas into shipped impact.
  • Shape engineering culture through mentorship, code reviews, and rapid iteration.

Requirements

  • You've shipped LLM-driven products or agent systems in production - LangChain, LangGraph, or custom orchestration.
  • You're fluent in Node.js, TypeScript, React, and familiar with Python for AI workflows.
  • You've run real systems on AWS (Fargate, Lambda, SQS) with PostgreSQL or similar.
  • You understand context management, retrieval, evals, latency, and observability in AI systems.
  • You thrive in high-velocity, low-ego teams where autonomy and accountability are the defaults.

Benefits & conditions

  • Fully Remote
  • $100,000 - $120,000 USD + meaningful equity
  • Unlimited holidays, remote setup allowance, learning & development budget
  • Premium AI tool access (ChatGPT Plus, Claude, Cursor, etc.)
  • Flexible engagement: B2B contract or via Deel (EOR)
  • Join a 15-person senior engineering team building AI infrastructure that's already in the wild.
