What is a software engineer internship?

A Software Engineer Internship is a temporary position where students or entry-level professionals gain hands-on experience in software development. Interns typically work on real projects, write code, debug issues, and collaborate with engineering teams. The internship helps develop technical skills, knowledge of software development processes, and familiarity with industry tools. It also provides networking opportunities and can lead to full-time job offers.

What kinds of projects or tasks do software engineer interns typically work on during their internship?

Software Engineer Interns are often assigned to real-world projects that may include developing new features, fixing bugs, writing automated tests, or improving documentation. They usually work as part of a development team under the mentorship of experienced engineers, which allows them to participate in code reviews, agile meetings, and collaborative problem-solving sessions. The exact responsibilities may vary, but interns are regularly exposed to the full software development lifecycle and are encouraged to ask questions and contribute ideas. This hands-on experience not only builds technical skills but also prepares interns for full-time roles after graduation.

What are the key skills and qualifications needed to thrive in the software engineer internship position, and why are they important?

To thrive as a Software Engineer Intern, you need a solid understanding of programming languages (such as Java, Python, or C++), algorithms, data structures, and typically be pursuing or have a degree in computer science or a related field. Familiarity with version control systems like Git, integrated development environments (IDEs), and sometimes issue tracking tools is often expected. Strong problem-solving abilities, a willingness to learn, and effective communication are key soft skills that help interns excel in collaborative environments. These skills ensure interns can contribute meaningfully to technical projects, integrate well with engineering teams, and grow rapidly within the organization.

Job description

About Voyis 

Voyis designs and manufactures high performance underwater optical sensors (lasers, cameras, lights)for underwater vehicles that expand capability and enhance understanding in underwater surveys and exploration. Our products have enabled our customers to survey more than 10,000km of ocean floor across all 7 continents, helping people better understand those remote, challenging environments.  

Our mission is to push the limits of what’s possible subsea and enable every underwater vehicle to see the depths like we see the surface. All our products are proudly designed and built in Waterloo. 

What you’ll do

We're looking for a Software Developer (Internal Tools) to build and maintain the software that keeps our teams moving. Internal tools are often treated as an afterthought — not here. We believe well-crafted tooling with a great user experience is a force multiplier: it streamlines processes, reduces errors, and gives our engineers and technicians time back every day. 

This role suits a developer with diverse coding experience who hasn't sacrificed fundamentals along the way. You'll work across languages, platforms, and problem domains — one week you might be building a GUI for a calibration workflow, the next automating a data pipeline or improving a deployment process. Curiosity and a willingness to learn unfamiliar domains (for example, sensor calibration or data quality) matter as much as your current toolkit. 

Core responsibilities

  • Design, build, and maintain internal tools and applications that streamline engineering and operational workflows 

  • Prioritize usability and user experience — internal users deserve polished, intuitive tools, not clunky scripts 

  • Write high-quality, well-structured, and maintainable code with appropriate testing and documentation 

  • Develop and support tooling across both Windows and Linux environments 

  • Collaborate closely with internal users (engineers, technicians, operations) to gather requirements, iterate on feedback, and measure whether tools actually improve their workflows 

  • Maintain and improve existing tools, managing technical debt pragmatically 

  • Contribute to team standards around code review, version control, and release practices 

Your qualifications   

  • 2–5 years of professional software development experience 

  • Strong experience in one or more Rust, C#, Go. Familiarity with C++ is a plus. — comfortable working across multiple languages and picking up new ones as needed 

  • Database management experience — schema design, administration, backups, query optimization 

  • Solid grounding in software development principles: clean architecture, testing, version control, code review, and maintainability — quality matters here 

  • Hands-on experience developing for and working in both Windows and Linux environments 

  • Strong sense of user experience — you think about the person using the tool, not just the code behind it 

  • Genuine willingness to learn new technical domains and processes (e.g., sensor calibration workflows) — you ask good questions and ramp up quickly 

  • Clear communicator who can work directly with non-developer users to understand their needs 

Bonus Points   

  • DevOps experience — CI/CD pipelines, build automation, infrastructure as code (big plus) 

  • Experience with Ansible for configuration management and automation (another big plus) 

  • Experience working with or alongside hardware — test rigs, sensors, lab equipment, or production hardware 

  • Familiarity with scripting and automating repetitive engineering or operational processes 

  • Exposure to robotics, computer vision, or sensor-driven systems 

Work Location 

This is primarily an in-person role based at our Waterloo headquarters. Some flexibility for remote work is available; however, fully in person is preferred and a minimum of four days on-site is expected to support close collaboration with the team who is nearly full time in office. 

The Perks 

  • 5 weeks of total time off, flexible work hours and a dedication to a work-life balance.
  • Employee-directed personal education funds to drive continuous learning
  • Profit-sharing within to celebrate our successes together
  • Regular company-wide social events
  • Health and vision benefits
  • RRSP Matching 

The Pay 

This opening is for an active vacancy. The salary range for this role is $80,000 to $100,000 dependent on skillset and experience. 

Why Join Voyis 

Voyis is a small, highly capable team of engineers and problem-solvers building technology used in some of the world’s most demanding environments. Our work has supported expeditions to iconic sites such as the Titanic and Endurance, and every team member has a visible impact on both our products and our customers. 

This posting is intended to fill an existing vacancy. Applications are reviewed by our team and we may use artificial intelligence (AI) to assist in screening or assessing candidates. This role requires legal authorization to work in Canada without sponsorship. 

At Voyis we value diversity and we’re proud to be an equal opportunity workplace. We are committed to creating an inclusive environment for all. We thank everyone who applies and for their interest in working for Voyis, however, only candidates selected for an interview will be contacted. No telephone or walk-in inquiries please.
