Software Engineer Intern

About Stem Health

Stem Health is building a new kind of primary care experience for people who want a more considered and relationship-focused approach to their health. Led by physicians and offered through a membership model, the company blends strong clinical care with a hospitality-driven experience in a thoughtfully designed flagship clinic at First Canadian Place, set to open in September 2026.

The organization’s care model is based on long-term relationships, data-driven decision-making, trust, and high-quality service.

The Opportunity

Software is a core part of how Stem Health operates. The systems that support care coordination, internal operations, and member experiences are being built carefully from the ground up, and the team is looking for someone who wants to actively contribute to that effort.

Stem Health is hiring a Software Engineer Intern for a 4-month term. This is hands-on engineering work: you will write production code, solve meaningful problems, and help build a product that is already in progress. The role is not focused on observation, note-taking, or passive participation — it is for someone who wants to build.

This position is well suited to a student or recent graduate with strong technical ability, a product-oriented mindset, and interest in working on software for a complex, real-world environment where reliability and impact matter.

What You’ll Work On

Feature development and product engineering

• Build and deliver features for both internal tools and member-facing products, such as member portals, care coordination tools, scheduling workflows, clinical integrations, and internal dashboards.
• Work across front-end and back-end layers depending on project requirements and your strengths; full-stack contributions are welcome.
• Turn product needs and design specifications into clear, maintainable, well-tested code that fits smoothly into current systems and APIs.
• Take part in sprint planning, code reviews, and daily stand-ups as a contributing member of the engineering team throughout the term.

Systems integration and API development

• Assist in building and maintaining connections between Stem Health’s systems and external platforms, including EHR/EMR software, scheduling tools, diagnostic lab services, payment systems, and communication tools.
• Work with RESTful APIs, help support data pipeline tasks, and contribute to dependable and secure data movement across the platform.
• Support cloud infrastructure setup, deployment workflows, and environment configuration where needed.

AI-enabled tooling, where relevant

• Based on interest and project availability, contribute to internal AI tools, including integrations with large language model APIs, retrieval-augmented systems, and workflow automation.
• Partner with the Technology Director on taking AI capabilities into production, including prompt design, evaluation of outputs, and implementation of guardrails.

Code quality and engineering practice

• Produce clean, readable, and well-documented code that others can maintain and extend.
• Write unit and integration tests as part of standard development work to improve reliability and confidence in the system.
• Look for bugs, slow performance, and technical debt proactively, and help improve the codebase as part of your normal workflow.

What We’re Looking For

• You are currently enrolled in, or have recently completed, a post-secondary program in Software Engineering or a closely related technical field.
• You have solid programming fundamentals and are comfortable in at least one modern language such as Python, TypeScript, JavaScript, or something similar; experience with back-end or full-stack development is helpful.
• You have exposure to web frameworks such as React, Next.js, FastAPI, Node.js, Django, or comparable tools, and you can learn new technologies quickly.
• You have worked with databases, APIs, and cloud platforms such as AWS, GCP, or Azure through coursework, projects, or practical experience.
• You are comfortable using Git, working in collaborative development environments, and contributing within an existing codebase.
• You think like a product builder: you consider the end user and care about whether the solution works well in practice, not just whether the code is correct.
• You can break down ambiguous problems into practical, executable steps and solve them methodically.
• You communicate well in writing and speaking, and can explain technical choices to both technical and non-technical teammates.
• Interest in healthcare, health technology, or software built in regulated or privacy-sensitive environments is an asset.

What You’ll Gain

• Hands-on engineering experience on a live product that is actively being developed and used by real people.
• Exposure to the full product lifecycle, from identifying the problem and designing a solution through deployment and iteration, in a fast-moving early-stage setting.
• Close collaboration with experienced engineers, product teammates, and cross-functional stakeholders, offering strong professional growth.
• Practical experience building software in a healthcare environment where privacy, reliability, and safety are critical.
• A portfolio of shipped work from a distinctive, mission-driven company that you can confidently discuss in future interviews.

Ideal Candidate

The best fit for this role enjoys writing code and building useful things. You are curious about how systems work, careful about quality, and motivated by the chance to see your work used by real people. You are comfortable asking questions when needed, honest about what you know and what you are still learning, and energized by contributing to something meaningful. You do not need to have everything figured out on day one — you need the drive to learn, the discipline to follow through, and the willingness to do the work.

Additional Information

This is a 4-month internship term based onsite in Toronto, Ontario, Canada. The role is part-time and is tied to a live engineering effort rather than observational work. The clinic referenced in the company overview is scheduled to open in September 2026.
