What does it take to build, improve, and scale the backend systems behind search, indexing, and machine learning? Are you curious about the systems that power information retrieval, index querying, and machine learning development at scale? Coveo is looking for Software Development Interns to join teams within Research & Development, where you’ll contribute to meaningful backend projects that support real-world products and client-facing solutions. Your mission? Help improve critical services, strengthen backend infrastructure, and gain hands-on experience in large-scale engineering environments. You could work on one of the following projects: Search API team: The team is responsible for how Coveo retrieves information from the index and for the surrounding technologies that support that flow. As an intern, you’ll contribute to refactoring initiatives that help align the Search API service with the rest of R&D, while learning how to make incremental changes to a critical service. Query-Index team: This team works on index query-related systems, including how Coveo retrieves information from the index and the related technologies that support that flow. As an intern, you’ll gain practical experience with regular engineering workflows while also owning a project from requirements gathering to delivery. ML Platform Building team: The team develops and maintains the model training platform used across Coveo. They provide the infrastructure, tools, and observability needed to experiment, access metrics, monitor workloads, and validate model performance. As an intern, you'll implement backend improvements that strengthen the platform's resilience and visibility, directly supporting the teams behind Coveo's AI-powered experiences. Your impact, day to day: Engage actively in daily stand-up meetings to discuss progress, roadblocks, and plans. Collaborate with team members to ensure alignment and effective communication.
