**About us** Gogolook is a leading TrustTech company founded in 2012 and listed on the Taiwan Stock Exchange in 2025 under the stock code 6902. With "Build for Trust" as its core value, the company has expanded its business from Asia to Europe and America. Gogolook’s AI technology is built on the world's largest database of digital scam data, encompassing phone numbers, websites, virtual currency wallet addresses, and other factors. The company provides diverse anti-scam and fintech services for both consumers and businesses. Its anti-scam offerings include the digital anti-scam app "Whoscall" and a range of enterprise scam prevention solutions in combination with "ScamAdviser." The Fintech BU empowers consumers through data-driven financial services and inclusive lending: （袋鼠金融）offers transparent matchmaking for financial products like credit cards, while JUJI（招財麻吉）provides an innovative microloan service for rapid, convenient funding during urgent financial needs. A foundation member of the Global Anti-Scam Alliance (GASA), Gogolook has also teamed up with a number of institutes such as the Taiwan National Police Agency Criminal Investigation Bureau, the Financial Supervisory Service of South Korea, Thai Royal Police, the Fukuoka city and Shibuya City government, the Philippines Cybercrime Investigation and Coordinating Center, and the Royal Malaysia Police and state government to fight scam, dedicated to creating a "scam-free environment." **Why you should join Gogolook** 1.

If you feel you fit the bill, come join us! **About the Intelligent Systems Lab (ISL)** The ISL team provides applied research and development capabilities to help achieve long-term strategic goals for Gogolook. Our typical project lifecycle is 6 months, focusing on a transition from ISL team principles to long-running applied R&D. We collaborate closely with other Gogolook teams to: - Evaluate product needs for intelligent solutions. - Propose solutions that use cutting-edge AI. - Create POCs (Proof of Concepts) to demonstrate viability. Together, ISL and Engineering teams meet both the short and long-term technology needs of the company. **Role Mission** As a Machine Learning Engineer, you will be a core part of ISL's modeling competency. Your mission is to implement, evaluate, and deploy machine learning models that turn Gogolook's first-party data into precise, reliable products that protect users from fraud. You will treat model quality as an experimental discipline — measured, not assumed — and bring statistical rigor to every result you ship. Your journey at Gogolook is designed for growth. At the beginning, you will build and train models with guidance, evaluate them with the right metrics, prepare and engineer the data they learn from, and document your work so others can reproduce it. Subsequently, we expect you to take full ownership of end-to-end ML solutions — designing the experiments, running the statistical analysis, optimizing for performance, and deploying to production. Over time you may lead advanced ML initiatives, guide experimental strategy, drive statistical rigor across the team, architect scalable ML infrastructure, and mentor junior engineers. ### Responsibilities - **Model Development**: Implement and train supervised and unsupervised models using standard frameworks under structured guidance. - **Model Evaluation**: Evaluate models with appropriate metrics and perform error analysis to understand where and why a model fails. - **Data Preprocessing & Feature Engineering**: Clean, transform, and engineer features to prepare data for training and testing. - **Experimentation**: Apply basic statistical-analysis and experimental-design methods to tune and optimize models. - **Deployment Support**: Help package, deploy, and monitor models within ISL's infrastructure, learning CI/CD and containerization practices. - **Collaboration**: Work in a shared codebase using Git; partner with Data Research Engineers, AI Engineers, and Product Managers to deliver value. - **Documentation**: Clearly document training processes, experiment design, assumptions, and outcomes, and communicate results to the team. ### Qualifications - **Proficiency in English**, both spoken and written, sufficient to collaborate, document, and present in an English-working environment. - Bachelor's degree in Computer Science, Statistics, Machine Learning, or a related quantitative field. - 2-4 years of experience in the related area depending on degree. - Hands-on experience building, training, and evaluating machine learning models with standard frameworks. - Highly **independent and self-motivated**, with the ability to manage multiple task items within a team environment. - Ability to learn from mistakes and a continuous drive to **seek self-improvement** in new skills and technical knowledge. - Strong **collaborative mindset**, acting as a good team player who understands how value is delivered both efficiently and responsively. - **Proactive communicator** who takes the initiative to voice concerns regarding technical risks and contributes to the creation and reduction of tech debt. ### Preferred Qualifications - Exposure to cloud ML platforms (AWS SageMaker, Google Vertex AI) for training and deployment. - Familiarity with **CI/CD and containerization (Docker)** for shipping models to production. - Comfortable working with **Data Research Engineers, AI Engineers, and Product Managers** to bridge data, modeling, and product. ### Skills & Competencies - Solid grasp of **ML fundamentals** — supervised and unsupervised learning, and model evaluation metrics. - Familiarity with popular frameworks: **scikit-learn, XGBoost, and TensorFlow or PyTorch**. - Experience with **data preprocessing and feature engineering**. - Basic statistics for model tuning and basic **experimental-design methods** for model optimization. - Proficiency in **Python**; comfortable with **Git** and collaborative coding. - Disciplined in clearly documenting training processes, underlying assumptions, and final results.
