Bonus points if you can understand Bahasa Indonesia. * Self-motivated, curious, and excited by the opportunity to build high-impact systems quickly. ## Description As an algorithm expert on the Search and Recommendations Platform team, you will work alongside top talent in Singapore, China, Indonesia, and India to shape the intelligence behind GoFood and GoPay systems. You will design and deploy cutting-edge search, recommendations, and monetisation models that power on-demand and financial use cases across Indonesia. In your first six months, you will play a key role in launching foundational platform capabilities and collaborating with business-facing data science teams, to drive business impact and improve user experience. If you are passionate about applying advanced algorithms to deliver real business outcomes, this is one of the highest-leverage roles in the company. What You Will Do * Design and optimise hybrid lexical-semantic retrieval pipelines (e.g., BM25, dense vectors, HNSW/LSH, generative retrieval) to improve precision and recall across GoFood and GoPay surfaces. * Build high-quality embeddings and relevance signals that capture user intent, cuisine and dish semantics, geolocation, delivery constraints, price sensitivity, and promotions. * Develop multi-task deep ranking models that balance conversion, diversity, merchant quality, and long-term user retention, integrating real-time signals such as promotions, surge, and stock availability. * Build personalised ranking layers and user behaviour models leveraging historical orders, preferences, and contextual features. * Engineer recommendation algorithms using collaborative filtering, graph-based methods, and sequence models for retrieval expansion (e.g., Q2Q2I, Q2I2I, U2I), including for cold-start merchants and new dishes. * Advance embedding quality for multi-modal data (text, images, behavioural signals) and use LLMs to enhance structured knowledge (taxonomy tagging, dish attributes, dietary labels). * Incorporate structured metadata, taxonomy signals, and knowledge-graph features into retrieval and ranking pipelines to improve semantic understanding and consistency. ## Related Videos - [ChatGPT vs Google: SEO in the Age of AI Search - Eric Enge](https://www.wearedevelopers.com/videos/1287-chatgpt-vs-google-seo-in-the-age-of-ai-search-eric-enge) - [Python-Based Data Streaming Pipelines Within Minutes](https://www.wearedevelopers.com/videos/1233-python-based-data-streaming-pipelines-within-minutes) - [Focoos AI: Building the Future of Computer Vision](https://www.wearedevelopers.com/videos/1659-focoos-ai-building-the-future-of-computer-vision) - [How Regex Works: The Secret Sauce Behind Pattern Matching](https://www.wearedevelopers.com/videos/1212-how-regex-works-the-secret-sauce-behind-pattern-matching) - [Tomb rAIder: AI Search with Kotlin](https://www.wearedevelopers.com/videos/1989-tomb-raider-ai-search-with-kotlin) - [Why and when should we consider Stream Processing frameworks in our solutions](https://www.wearedevelopers.com/videos/1085-why-and-when-should-we-consider-stream-processing-frameworks-in-our-solutions) ## Related Articles - [What Are Large Language Models?](https://www.wearedevelopers.com/magazine/304-what-are-large-language-models) - [SEO in an AI world - Google vs. ChatGPT and survival tips for content creators](https://www.wearedevelopers.com/magazine/534-seo-in-an-ai-world-google-vs-chatgpt-and-survival-tips-for-content-creators) - [Dev Digest 102 - Race conditions](https://www.wearedevelopers.com/magazine/386-dev-digest-102-race-conditions) - [The Top ChatGPT Plugins for Developers in 2023](https://www.wearedevelopers.com/magazine/259-the-top-chatgpt-plugins-for-developers-in-2023) - [Got AI ideas but no money?
