Internship Operating Engineer Jobs in Toronto, ON

NexScale is an AI-native software company on a mission to extend human longevity by empowering wellness and fitness businesses with intelligent, human-centered AI.

Our flagship product, Chloe, is an AI Business Partner for boutique wellness and fitness studios. Chloe helps owners improve member retention, reduce burnout, and build stronger communities-by turning everyday operational data into proactive, empathetic actions.

We are not building another generic SaaS platform.
We are building agentic AI systems that reason, decide, and act inside real business operations-without increasing cognitive load for non-technical operators.

This is not a short-term, observational internship.

We intentionally design internships at NexScale as a talent pipeline for long-term contributors. This role is best suited for candidates who already have prior industry experience in software engineering and want to deepen their skills in AI-native, production-grade product development.

Exceptional performance during the internship may lead to:

• A full-time role at NexScale, or
• An extension of the internship for 12 months or longer, depending on mutual fit, funding structure, and team needs.

This role is a strong fit if you:

• Have hands-on software engineering experience in real codebases
  (internships, co-ops, startups, research labs, or production teams)
• Bring a strong AI foundation and interest in applied, product-embedded AI
• Are comfortable using AI-assisted development tools to accelerate delivery
• Care about building systems that create real business and human impact
• Take ownership, communicate clearly, and follow through

You do not need to be senior.
You do need to be capable, curious, and accountable.

You will contribute directly to Chloe's Retention Intelligence Layer, helping transform fragmented data into clear insights and actions for studio owners.

• Build and ship features across NexScale's SaaS platform
• Develop backend services, APIs, and data pipelines
• Contribute to operator-facing dashboards and insights
• Support integrations with CRM and studio management platforms

• Implement AI-driven workflows, recommendations, and automations
• Work with agentic patterns: triggers, decision logic, and feedback loops
• Embed AI into real product experiences-not demos or experiments

• Participate in code reviews, testing, and deployments
• Write clean, maintainable, production-grade code
• Balance speed with quality in a fast-moving environment

By the end of the internship, a strong intern will have:

• Shipped 1-2 production features used by real customers
• Contributed meaningfully to an AI-driven workflow or insight
• Worked within at least one real integration or data pipeline
• Demonstrated strong ownership, judgment, and reliability
• Shown readiness for expanded scope through full-time hiring or extended internship

• Prior industry experience in software engineering (internships, co-ops, startups, or applied research)
• Strong programming skills in Python and/or TypeScript/JavaScript
• Experience with modern frameworks (e.g., React, Node.js, FastAPI)
• Solid foundation in AI / LLM concepts
• Fluent in using AI-assisted development tools responsibly
• Eligible for Canadian internship grant programs (graduated not more than 2 years ago from a Canadian university)
• Strong communication skills, attention to details and coachability

• Experience building LLM-based applications or agentic systems
• Familiarity with cloud platforms like AWS
• SaaS or customer-facing product experience
• Interest in wellness, fitness, or retention-driven business models

• Work closely with a 3 experienced founder and a team of seasoned engineers, AI experts, and production-grade AI agents at a truly AI-native company based in Canada
• Build applied, production-grade AI that is actively used by real customers-not demos or internal tools
• Gain hands-on experience designing and shipping agentic AI systems in real business environments
• See how your work directly impacts real businesses, real operators, and real communities
• Join a high-bar team that values clarity, empathy, ownership, and execution over titles or bureaucracy

We view internships as a two-way commitment.

When there is strong mutual fit and sustained impact, we prefer to extend and grow people rather than restart hiring. If you're looking for meaningful ownership, real responsibility, and a clear path forward-this role is designed for you.

Attention to detail and operational excellence are essential to us. Please read the job posting carefully and submit:

• Your resume, which must include a link to your LinkedIn profile
• A short cover letter explaining why you are a strong fit for this role

Please note that we will only contact candidates who are selected to move forward to the next screening step.
