Grow together
You will join an engineering team focused on accelerating enterprise delivery and transforming customer interactions through AI. In this role, you will take technical ownership across all phases of the software lifecycle—from conversational flow architecture and prompt design to backend integration, continuous automated testing, and CI/CD deployment.

Key responsibilities include:

• Conversational AI & Agent Architecture: Design, implement, and maintain conversational applications, interactive voice/chat pipelines, and autonomous agent workflows utilizing platforms such as Happyrobot, Cognigy, Google Cloud Conversational AI / Dialogflow / Vertex AI Agents, or modern Agent Development Kits (ADK).
• Advanced Prompt Engineering & LLM Orchestration: Develop, evaluate, and optimize system prompts, few-shot prompting strategies, tool-calling chains, and dynamic retrieval patterns (RAG) to ensure accurate, context-aware, and low-latency agent execution.
• Enterprise Integration & Backend Development: Engineer robust, reusable microservices and integration middleware in Java (Spring Boot) and/or Python to link conversational layers seamlessly with core Booking Service APIs, messaging buses, and ERP backends.
• System Integration & Build: Define, configure, and maintain automated CI/CD pipelines, containerized deployments (Docker, OpenShift, Kubernetes/AKS), and environment configurations ensuring reliable service releases.
• Quality Assurance & AI Guardrails: Formulate automated regression test suites, conversational intent validation datasets, and security guardrails to minimize hallucinations, prevent prompt injections, and enforce enterprise data privacy and OWASP security standards.
• Operational Monitoring & Continuous Improvement: Monitor conversational telemetry, dialogue completion rates, and fallback metrics; execute root-cause analysis on production incidents and fine-tune dialogue intent handling.
• Technical Mentorship: Provide guidance and conduct rigorous code and architecture reviews for less experienced engineers, establishing best practices in conversational design, prompt optimization, and modular software engineering.

Great Team
Hi, my name is Chong Jin Chun and I’m a team manager. I started my career at DHL IT Services back in 2007, when I took a role as Senior Software Engineer in the Customer Service team. Gaining more hands-on experience with Solution Architecture has always fascinated me, so from there, I moved fast through the company ladder and soon landed a Principal Architect role. In 2019, I moved to a management role, being Team Manager. Together with the strong support of a multinational & diverse team, we are working on our common ambition – technology. Looking forward to having you onboard!
