Job Title Senior Full Stack Engineer – AI Systems

Location Remote

  • Time Zone Flexible / Aligned to HQ Time Zone

Role Overview We are scaling our agentic AI capabilities and are looking for a Senior Full Stack Engineer to help us build the systems that power autonomous, context-aware agents across our platform. This is a high-impact, high-ownership role for an engineer who wants to shape how intelligent automation is experienced by thousands of enterprise users.

You will work at the frontier of agentic AI — designing agents that can reason, plan, and act — while also building the full stack infrastructure and interfaces that bring those capabilities to life in a production SaaS environment. If you are energised by complex systems, semantic reasoning, and the challenge of making AI reliable at scale, this role is built for you.

Key Responsibilities

  • Develop full stack features supporting the deployment, monitoring, and management of AI agents within our SaaS platform
  • Build and extend the RPA agent layer — designing agents that reason, adapt, and operate reliably in production
  • Implement and iterate on semantic context mechanisms that equip agents with structured, domain-relevant knowledge
  • Create intuitive frontend interfaces that give users visibility and control over agent behaviour and outcomes
  • Integrate with third-party AI services, LLM APIs, and enterprise data sources
  • Work in a cross-functional squad alongside product managers, ML engineers, and UX designers
  • Help define technical standards and patterns for agentic system development across the engineering organisation

Required Qualifications

  • Senior-level full stack engineering experience with a strong track record of delivery in complex systems
  • Strong experience with agentic AI systems — including tool-use, memory, planning, and multi-agent coordination
  • Practical knowledge of RPA concepts and automation workflow design
  • Familiarity with semantic context patterns and how to structure and surface knowledge for AI consumption
  • Proficiency across both backend (Python or Node.js) and frontend (React / TypeScript)
  • Demonstrated ability to lead technically within a collaborative, cross-functional team
  • Must have prior remote work experience and be comfortable working autonomously within a distributed engineering team

Preferred Qualifications

  • Experience with orchestration frameworks such as LangGraph, AutoGen, or CrewAI
  • Exposure to enterprise integration patterns including event-driven architecture
  • Background shipping features in a B2B SaaS environment
  • Familiarity with vector databases and embedding-based retrieval systems

  • Agentic frameworks (LangChain, LangGraph, AutoGen, CrewAI, or similar)
  • LLM APIs (OpenAI, Anthropic, or similar)
