Who we are

We build and operate mission-critical digital products used at scale. Our teams partner closely with stakeholders to design and deliver practical, product-centric solutions that address real operational needs.

AI is a core part of our work — from intelligent automation and search, to large language model

(LLM)-powered applications, agentic workflows, and decision-support systems. Our engineers work across multiple types of initiatives: rapid Proof-of-Concepts (POCs), shared AI frameworks, and production-grade systems.

We operate in a cloud-native environment (AWS/Azure), build primarily with Python and JavaScript/TypeScript, and deliver modern web applications using frameworks such as React or Vue.js. We value strong engineering fundamentals, pragmatism, and operational excellence.

What you will be working on

As a Fullstack AI Engineer, you will:

• Design, build, and maintain end-to-end AI-powered applications, covering frontend, backend, and AI components.
• Deliver Proof-of-Concepts (POCs) by rapidly building working prototypes to validate feasibility and demonstrate value within short timeframes.
• Build and enhance core AI frameworks, libraries, and reusable components to enable faster and more consistent AI development across the team.
• Develop production-grade AI systems, ensuring scalability, reliability, security, and maintainability.
• Implement LLM-powered features, including prompt design, orchestration, structured outputs, and evaluation.
• Build agentic or multi-step AI workflows using modern AI frameworks (e.g. LangGraph, LangChain, or similar).
• Design and integrate search and retrieval systems, including data ingestion, vector indexing, and hybrid search.
• Develop backend services and APIs using Python-based frameworks (e.g. FastAPI, Django) and/or Node.js/Nest.js.
• Build intuitive user-facing interfaces using modern frontend frameworks (e.g. React, Vue.js).
• Contribute to LLMOps / MLOps practices, including model versioning, evaluation, monitoring, and deployment workflows.
• Work with cloud infrastructure, containerisation, and CI/CD pipelines to deploy and operate AI systems.
• Balance speed and robustness appropriately across POCs, shared frameworks, and production systems.
• Collaborate closely with product managers, designers, other engineers and stakeholders to translate requirements into working solutions.
• Debug, monitor, and improve systems in production, upholding high standards of operational excellence.
