About the Role The Full Stack AI Engineer will help us bring AI capabilities into our products. This is a hands-on role for someone who can integrate, deploy, and optimize AI models (open-source or API-based) into real-world applications, without necessarily building them from scratch. You will work across the stack — from frontend integrations to backend pipelines — and collaborate with data teams to analyse experiments and improve performance. Responsibilities Integrate AI models (open-source frameworks, hosted APIs, or in-house tools) into production applications using JavaScript/TypeScript and Python . Develop end-to-end AI-powered features , including frontend interfaces, backend APIs, and data pipelines. Work with SQL and PySpark to analyse experimental results, measure performance, and generate insights. Design, test, and refine prompts for large language models (prompt engineering) to achieve desired outputs and improve user experience. Collaborate with product, data science, and engineering teams to define requirements and deliver solutions. Optimize application performance, scalability, and maintainability. Stay updated on AI APIs, frameworks, and integration best practices. Required Skills & Experience 2–4 years of professional software engineering experience. Proficiency in JavaScript/TypeScript and Python . Solid understanding of frontend and backend development principles. Strong SQL skills and experience with PySpark or similar big data frameworks. Experience integrating pre-trained AI models (e.g., via APIs, Hugging Face, OpenAI, TensorFlow.js, or similar). Familiarity with REST and GraphQL APIs. Strong debugging and problem-solving skills. You have an open-minded approach to content and are comfortable dealing with NSFW elements while upholding our ethos of user privacy and safety. Nice-to-Have Experience with prompt engineering and fine-tuning for different AI use cases. Experience with cloud platforms (AWS, GCP, Azure). Familiarity with data visualisation tools (e.g., Plotly, Tableau, Superset, Databricks). Experience with CI/CD and containerization (Docker, Kubernetes).
