Job summary

Hire Hangar is seeking a Senior AI Platform Engineer to own the contextual intelligence layer powering our AI agents within a SaaS ecosystem. You will shape how agents understand, reason, and act with precision, while building frontend surfaces for end users.

This role blends AI engineering with platform development, requiring strong frontend skills (React/TypeScript) and Python backends, plus experience with knowledge graphs, RDF/OWL, and LLM integrations.

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.
Must have prior remote work experience and demonstrated ability to collaborate asynchronously across distributed teams.

Responsibilities

Design and maintain semantic context layers — knowledge graphs, ontologies, and structured context stores — that inform agent behaviour.
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.
