Computer Science Internship jobs in Vancouver, BC

TITLE: Machine Learning Engineer Intern – Voice AI

POSITION OVERVIEW: 

The Machine Learning Engineer Intern will contribute to the development of ALEBEX's production Voice AI systems, working across machine learning model training, post-training, evaluation, and real-time inference. This role offers hands-on experience with speech models, large language models, GPU-based inference, low-latency systems, and real-time voice pipelines.

Working closely with the engineering team, the successful candidate will help fine-tune, evaluate, optimize, and deploy machine learning models used in production voice agents. This is a hands-on engineering role involving real models, GPUs, production inference workloads, and real-time systems.

This position is ideal for a student or recent graduate with strong Python and machine learning fundamentals who is interested in applied AI and wants practical experience taking models from training and experimentation into production environments.

EMPLOYMENT TYPE: Co-op / Internship 4- or 8-Month Contract

COMPENSATION: $30 per hour

LOCATION: Downtown Vancouver, BC (Alexander Innovation Centre)

WORK WEEK: Monday – Friday; Full-time preferred.

ABOUT ALEXANDER INNOVATION CENTRE (AIC):

Alexander Innovation Centre is a Vancouver-based innovation hub supporting the development and commercialization of emerging technologies and fostering collaboration between industry, education, and entrepreneurs. Located in downtown Vancouver, the Centre provides a collaborative environment for technology development, applied innovation, and hands-on learning opportunities.

This position is based at the Alexander Innovation Centre, where the successful candidate will work closely with the ALEBEX AI team on the development of production AI technologies.

ABOUT ALEBEX:

ALEBEX AI is a Canadian-owned AI company based in Vancouver, BC, focused on developing an agentic workforce platform where AI agents perform real operational work — including answering calls, qualifying leads, and executing multi-step tasks — under human supervision.

The platform enables AI agents to operate across voice and digital channels, combining real-time communication, proprietary voice technology, AI models, integrations, and orchestration to execute real business workflows. It operates on Canadian infrastructure, including on-premises AI inference, and is currently used in production by real clients.

ALEBEX is a small, fast-moving team focused on developing practical AI solutions for real-world business applications. Its technology is built for production use, with active customers and operational workflows rather than demonstrations or experimental prototypes.

The successful candidate will work with the ALEBEX AI team on the development, evaluation, and optimization of machine learning models powering its Voice AI platform as part of this internship.
