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

Tools & Technology
Python / Node.js

React / TypeScript

Agentic frameworks (LangChain, LangGraph, AutoGen, CrewAI, or similar)

LLM APIs (OpenAI, Anthropic, or similar)

RPA platforms and automation tooling

Slack, Zoom, Google Workspace
