Job Summary

Build and iterate algorithms powering POI (Point of Interest) data for a Location Based Services platform, including data mining, quality evaluation, consistency validation, and intelligent review. Design agent modules (tool invocation, memory, skill orchestration, retrieval) with self-healing and robust fallbacks. Create evaluation and regression testing for non-deterministic outputs, apply LLMs for POI improvements, and deliver end-to-end engineering through AI coding workflows.

Location: Singapore

Workplace: Onsite

Employment Type: Full time

Job Function: Solutions Engineering & Sales Engineering

Seniority: Mid level

Key Responsibilities

•Design and develop algorithms for in-house construction of POI data, including data mining, quality evaluation, consistency validation, and intelligent review systems.
•Design and implement core Agent modules (tool invocation planning, memory management, skill orchestration, retrieval), emphasizing self-healing capabilities, fallback strategies, and edge-case handling.
•Build an Agent evaluation framework by defining success metrics, designing regression testing for non-deterministic outputs, and quantifying trade-offs across cost, latency, and quality.
•Drive use of large language models in POI scenarios, including fine-tuning, model distillation, knowledge base construction, and retrieval systems to improve POI data quality.
•Deliver high-efficiency end-to-end engineering outcomes from algorithm design to deployment using AI coding workflows and independently iterating algorithms via data insights.

Key Requirements

•Strong problem diagnosis and troubleshooting skills to break down issues, form hypotheses, and validate quickly (e.g., abnormal model loss or unexpected Agent behaviors).
•Solid system design mindset emphasizing stability, fallback strategies, fault tolerance, and edge-case handling.
•Strong programming fundamentals with data structures and algorithms, writing readable, debuggable, maintainable code.
•Hands-on model iteration experience in one or more areas: data mining, deep learning, computer vision (CV), large language models (LLM), or masked language models (MLM).
•Preferred: experience with LLM fine-tuning and preference learning, plus designing Agent/Skill/Memory modules or production non-deterministic systems (recommendation/search/content understanding).
