Internship Developer information

What skills and qualifications are needed to thrive as an internship developer?

To thrive as an Internship Developer, you need a foundational understanding of programming languages such as Java, Python, or JavaScript, along with coursework or a degree in computer science or a related field. Familiarity with version control systems like Git, basic software development tools, and knowledge of databases are typically expected. Strong problem-solving abilities, eagerness to learn, and effective communication skills help interns collaborate and adapt quickly. These skills and qualities are essential for contributing meaningfully to projects and maximizing learning during the internship experience.

What kind of mentorship and learning opportunities can internship developers expect during their placement?

Internship Developers typically work closely with experienced software engineers and team leads who provide guidance through code reviews, pair programming, and regular check-ins. Most organizations assign interns to real-world projects, allowing them to contribute meaningful code while learning best practices in software development. It's common to attend team meetings, participate in sprint planning, and receive feedback on both technical and soft skills, which helps interns grow rapidly and gain a strong understanding of the professional development process.

What is an internship developer?

An Internship Developer is a student or recent graduate who works temporarily at a company to gain practical experience in software development. They assist professional developers with coding, testing, debugging, and documentation under supervision.

Quantitative Developer

Quadrature Capital

London, ON • On-site

Full-time

Re-posted 13 days ago


Job description

At Quadrature, we're building the ultimate automated trading system: one that ingests data, forms views, executes in the market, and learns from the result to get better and faster. Every component - research infrastructure, low-latency stream processing, distributed data systems, trade execution, observability - is part of that system. The goal is for human effort to compound, rather than be spent solving the same problems again and again.

Our Quantitative developers work across all aspects of this system and we're always on the look out for exceptional quant developers and software engineers who want to help build it. Where you might join depends on your strengths and interests.

What we're looking for

  • Strong programming skills - we primarily work with Python, C++ and Rust, but we care more about how you think than the languages you've used.
  • Sharp design instincts and experience building or operating distributed systems.
  • Genuine curiosity about how systems work: how they fail, how they're operated, and how they evolve.
  • Care for the people and code around you, and the drive to keep making both better.

Note: This role is for candidates who have already completed their studies. If you're still studying or haven't yet graduated, we'd love you to apply to our internship programme instead.
If you want to do the best work of your career, we'd love to hear from you.
