Job Responsibilities

Intelligent Advertising Bidding Engine Development: Lead the design and implementation of bidding strategy algorithms for overseas performance advertising media including Google and Meta. Apply machine learning, operations research optimization, and reinforcement learning to design global intelligent bidding and budget allocation engines, achieving automated globally optimal decision-making under multi-dimensional business constraints such as total budget and ROI.

Revenue Forecasting and Elasticity Prediction: Develop deep understanding of business logic across flight, hotel, and other product lines; integrate internal and external dynamic features to optimize fine-grained conversion rate and revenue prediction models. Leverage causal inference techniques to build marginal revenue and elasticity prediction models for advertising regulation, accurately forecasting traffic, cost, and order elasticity under different bidding settings to enable precise scale and ROI control.

Exploration-Exploitation Mechanism Design: Design low-cost intelligent traffic expansion and product testing strategies; scientifically quantify system uncertainty; achieve optimal balance between high-conversion product monetization and long-tail potential exploration; fully unlock global market traffic and inventory product potential.

Product Selection and Full-Chain Advertising Optimization: Optimize product selection models; close the strategic loop between product selection qualification and advertising bidding; expand algorithm application boundaries in marketing scenarios.

Strategy Evaluation and Implementation: Lead the design of scientific strategy experimentation and causal evaluation frameworks; own end-to-end strategy development, deployment, and performance monitoring.

Business Communication and Collaboration: Translate complex algorithm logic and data performance into clear business language; collaborate efficiently across teams to jointly drive business growth.

Qualifications

Bachelor's degree or above in Computer Science, Statistics, Operations Research, Applied Mathematics, or related fields.

3+ years of relevant experience; priority given to candidates with core module leadership experience in advertising bidding algorithms, commercial monetization, or operations research optimization.

Proficient in commonly used machine learning and deep learning models; familiar with mainstream frameworks such as TensorFlow/PyTorch; deep expertise and proven implementation experience in at least one of operations research optimization, causal inference, or reinforcement learning.

Proficient in at least one programming language including Python/Java/C++; skilled in data processing using SQL/Spark and other tools; capable of scientific experimental design and evaluation analysis.

Excellent business and data acumen; ability to rapidly abstract complex business pain points into clear algorithmic problems. Capable of designing robust degradation and fault-tolerant algorithm solutions when facing imperfect real-world data systems (e.g., latency, sparsity).

Strong ownership mentality, accountable for strategy business outcomes; excellent cross-team collaboration and communication skills; rapid learning ability.
