Original job description

About Us:
AltaML is an applied artificial intelligence company, building and deploying solutions for organizations where the problems are real and the stakes are high, across public sector, construction, energy, and finance.

We believe in making small bets, failing fast, and being better together. We are on the lookout for creative problem-solvers, out-of-the-box thinkers who strive to solve big problems alongside clients, and early tech adopters driven to achieve success.

We don't hire for fit; we hire to add. We are looking for people who play by our core values of being: Agile, Gritty, Humble, and Happy. If you're passionate about AI/ML, thrive in a dynamic environment, and want to work with a diverse team of wickedly smart people, we want to hear from you!

About the Role:
Please note: This is a 4 or 8-month opportunity for current students looking for work experience starting in January 2027.
As an Associate Software Engineer you’ll play a hands-on role in building and scaling our agentic platform - an intelligent, adaptive system designed to automate workflows and power smarter decision-making. You’ll collaborate with engineers, product managers, and designers to develop clean, efficient code that drives both reliability and innovation.

Your work will span frontend and backend development, from fixing bugs and resolving integration challenges to developing new features and improving platform performance. You’ll also have the opportunity to work directly with AI and agentic solutions, leveraging these tools to optimize development, accelerate delivery, and shape how intelligent systems interact with one another.

This role is ideal for someone who’s passionate about modern software engineering, eager to deepen their technical foundation, and excited to contribute to a platform at the frontier of AI and automation.

Location: This posting is for an existing vacancy for a candidate based in Edmonton, Calgary, Toronto.

Participating Universities: This opportunity is currently open to anyone that is currently enrolled at the U of Alberta, U of Calgary, U Waterloo, U of Toronto. As this is a Mitacs funded opportunity, please reach out if you have questions regarding your eligibility.

Application Process:
Step 1: Apply

Step 2: You will be notified prior to the application deadline if you are moving to the next stage (via email correspondence)

Step 3: Online technical assessments

Step 4: 45 minute interview

Step 5: Background checks and offer

Step 6: Welcome to AltaML!

What you'll do:

Develop and maintain high-quality, well-documented code across both frontend and backend systems
Troubleshoot and resolve bugs, integration issues, and performance bottlenecks in production and staging environments
Implement new features and enhancements, particularly those that improve dashboard usability and data visibility
Collaborate closely with cross-functional teams to translate technical requirements into scalable solutions
Leverage AI and agentic development tools to automate testing, improve code efficiency, and streamline CI/CD pipelines
Contribute to technical documentation, code reviews, and agile workflows to ensure strong engineering practices and maintainable codebases
Stay current on software trends, frameworks, and architectures - bringing new ideas to strengthen our agentic infrastructure

What you bring:

Progress toward a Bachelor’s degree in Computer Science, Software Engineering, or a related technical field
Proficiency in one or more modern programming languages such as Python, JavaScript, TypeScript, or Node.js
Solid understanding of the Software Development Life Cycle (SDLC) and agile methodologies
Familiarity with frontend frameworks (React, Vue) or backend technologies (APIs, databases, microservices, or cloud infrastructure)
Exposure to machine learning concepts or experience working with agentic systems is an asset
Strong problem-solving, debugging, and analytical skills, with a focus on clean, maintainable code
A collaborative mindset and the ability to learn quickly in a dynamic, evolving technical environment

Responsible AI (RAI)
AltaML employees, contractors, and associates must be trained and well-versed in the importance of Responsible AI and empowered to enact RAI principles by developing and deploying AI solutions. They should also be empowered to raise and escalate RAI concerns as required.

AltaML is responsible for elevating public discourse and awareness of AI through open, transparent communications with the broader public.
