Full-Stack AI & Automation Engineer

Human Resources - Strategic Planning & Analytics CoE

ABOUT THE TEAM & YOUR ROLE

Strategic Planning & Analytics team is architected to move beyond traditional HR, functioning as a strategic engine that fuels ST’s growth through five specialized pillars: Business Partnerships, Products & AI, Workforce Insights, Data Science, and Workforce Planning Architecture. We are currently in an ambitious build-phase, moving away from legacy processes to create a sophisticated, tech-enabled function that mirrors the engineering excellence of the semiconductor industry. We don’t want to just manage headcount; we want to orchestrate the future of HR using AI.

As a member of this team, you won’t be working in a silo. You will be at the intersection of human capital and advanced technology, leveraging AI and data science to solve complex organizational challenges and expected to be a foundational builder. We are looking for pioneers to help us design and implement our first generation of advanced analytics and AI-driven products. You won't just be using technology—you will be architecting the roadmap, selecting the tools, and establishing the frameworks that will define how ST manages its global talent for years to come. If you are energized by the challenge of redefining the "H" in HR through the lens of data and innovation, you’ve found the right place.

Responsibilities:

• End-to-End AI Prototyping: Architect, build, and deploy conversational bots and transactional AI agents from scratch in a sandbox environment.
• Workflow Orchestration & Automation: Design and manage complex, multi-system automation workflows using tools like n8n to automate actions (e.g., orchestrating system lookups, mock API executions, and conditional task routing).
• LLM Integration & Prompt Engineering: Integrate prototypes securely with internal OpenAI/ChatGPT APIs, mastering prompt design, function calling, tool use, and state management.
• Interface & UI/UX Evolution: Build lightweight, responsive web interfaces (e.g., Streamlit, Next.js) for quick stakeholder testing, ensuring the backend logic is decoupled via webhooks for future migration into Microsoft Teams.
• Code Hygiene & Handoff Documentation: Maintain code transparency, track version changes, and collaborate efficiently using GitHub. Author structured "Industrialization Blueprints" (JSON payloads, API mappings, and logic flows) to seamlessly hand over for full scale production

Required Background & Skills:

• AI Orchestration Frameworks: Expert-level workflow creation using tools like n8n (advanced JavaScript/Python execution nodes, webhooks, and sub-workflows) or equivalent orchestration frameworks
• AI & LLM Mastery: Practical experience implementing conversational APIs, embedding architectures, vector stores, and advanced prompt engineering constraints.
• Full-Stack Core Development: Strong programming proficiency in Python and/or JavaScript/Node.js. Comfort writing clean API connectors, handling RESTful requests, parsing JSON, and maintaining code via GitHub.
• Enterprise Collaboration Ecosystems: Prior familiarity or structural understanding of building integration layers, bots, or webhooks for the Microsoft 365 / MS Teams ecosystem is highly desirable.
• Candidate should possess “Can-do” attitude, with an ability to thrive in an unstructured environment
• 9 to 12 years of software engineering/automation experience (with at least 2–3 years focused on building AI agents/bots from scratch).
• Masters/ PhD in Computer Science, Information Technology equivalent
• Understanding of HCM systems like Oracle is an added advantage
• Excellent English, quantitative, technical, and storytelling skills
