Senior Software Engineer - AI Applications

Job Description

Job Description
At Ubisoft, we are redefining how business teams interact with information through the power of AI. Our focus is on building or assembling applications that enable smarter, more interactive, and document-rich solutions. From hybrid search, question-answering and document drafting to research (legal, consumer, marketing), from conversational experiences to agentic processes, we are creating tools that empower users to extract insights, make decisions, and drive innovation.
We are seeking a highly experienced Senior Software Engineer to join our team in charge of the development of scalable back-end systems that power these cutting-edge AI applications. This is a unique opportunity to work at the intersection of AI, large-scale data processing, and cloud infrastructure, with significant room for growth and impact.

Responsibilities
As a Senior Software Engineer – AI Applications, you will play a critical role in designing and building the back-end systems that enable our (mostly RAG-based) solutions. You will work on challenges such as integrating large language models (LLMs) with retrieval systems, optimizing hybrid search pipelines, and building document-rich applications that deliver real-world value. This role requires a deep understanding of modern AI/ML integration, as well as a passion for solving complex problems.
• Architect and Develop Back-End Systems: Design and implement scalable, high-performance back-end solutions to support AI applications, including data processing pipelines, document processing systems, and cloud-based infrastructure.
• Optimize Performance: Ensure low-latency, high-throughput serving of AI models and APIs, optimizing for both speed and reliability.
• Collaborate Across Teams: Partner with data scientists and ML engineers to integrate AI models into production systems, ensuring seamless deployment and monitoring.
• Cloud Infrastructure: Build and maintain cloud-native solutions using platforms like AWS, or Azure, with a focus on scalability, security, and cost-efficiency.
• Technical Leadership: Mentor junior engineers, conduct code reviews, and contribute to the overall technical strategy of the team.
• Stay Ahead of the Curve: Keep up-to-date with the latest trends and technologies in AI, cloud computing, and software engineering, and bring innovative ideas to the table.
Qualifications
We are seeking a seasoned professional with a strong technical background and a passion for building world-class AI applications.
Must-Have Qualifications:
• Experience: strong professional and practical software engineering experience, with a focus on back-end development in a compute-intensive and/or data-intensive environment.
• Programming Skills: Expertise in languages such as Python, Java, Rust, or C++.
• Cloud Expertise: Hands-on experience with cloud platforms (AWS, GCP, Azure) and containerization technologies (Docker, Kubernetes).
• AI/ML Integration: Experience deploying and serving machine learning models in production environments.
• System Design: Strong understanding of system architecture, microservices, and API design.
• Problem-Solving: Proven ability to tackle complex technical challenges and deliver innovative solutions.
Nice-to-Have Qualifications:
• Familiarity with Deep Learning architectures, Language Models, Vision Models
• Understanding of RAG-based architectures (indexing, embedding, vector databases and search, query processing)
• Experience with serverless architectures and event-driven systems.
• Contributions to open-source projects or publications in relevant fields.
