You will work at the cutting edge of how structured knowledge is used to make AI agents smarter and more reliable. This is a role for an engineer who thinks deeply about context, meaning, and how machines can be equipped to make better decisions — and who can also build the frontend surfaces that make those capabilities accessible to end users.

- Develop full stack features that allow users to configure, monitor, and control AI agents through intuitive interfaces
- Integrate RPA agents with semantic reasoning capabilities, enabling context-aware automation at scale
- Build and maintain data platform frontends that provide real-time visibility into agent activity and data flows
- Work closely with product and data science teams to translate business requirements into intelligent automation solutions
- Champion engineering quality through testing, documentation, and architectural consistency Required Qualifications
- Senior-level full stack engineering experience
- Deep understanding of semantic technologies — knowledge graphs, RDF/OWL, ontologies, or entity resolution
- Hands-on experience building or consuming AI agent frameworks
- Strong frontend skills with React or similar, including data visualisation libraries such as D3.js or Recharts
- Experience with Python-based backends and ML service integration
- Comfort working in fast-moving SaaS product environments
