What are Summer Software Developers?

Summer Software Developers are typically students or early-career professionals who take on short-term, often internship-based, roles in software development during the summer months. Their responsibilities can include writing and testing code, collaborating with teams, learning new technologies, and contributing to real projects. These positions offer valuable hands-on experience and a chance to explore the software industry. Summer Software Developers often work under the guidance of senior engineers and are expected to quickly learn and adapt to new tools and practices.

What are the key skills and qualifications needed to thrive as a Summer Software Developer, and why are they important?

To thrive as a Summer Software Developer, you need a solid grasp of programming fundamentals, problem-solving skills, and coursework or experience in computer science or related fields. Familiarity with version control systems like Git, coding languages such as Python or Java, and development environments is typically required. Strong collaboration, adaptability, and effective communication make you stand out when working on team projects or receiving feedback. These skills are crucial for quickly contributing to real-world software projects and making a positive impact during a short internship period.

What types of projects and technologies do Summer Software Developers typically work on during their internship?

As a Summer Software Developer, you can expect to work on real-world projects that often align with the company's current product goals or internal tools. Common technologies include popular programming languages like Python, Java, or JavaScript, as well as frameworks and tools used by the team. Interns usually collaborate closely with full-time engineers, participate in code reviews, and attend team meetings, providing valuable exposure to agile development practices. The projects are designed to be challenging yet achievable within the internship timeframe, offering a hands-on learning experience and a chance to make a tangible impact.

Job description

ARE YOU INTERESTED IN A WORKPLACE THAT HAS...

Flexible Hybrid Work Environment 
Summer Hours
Start your weekend earlier during the summer months!
 Paid Vacation Days Off (in addition to Personal Days)
An IDEAS (Inclusion, Diversity, Equity, Awareness, Solidarity) team
Weather is inclusive, we will be too. Our IDEAS team is committed to making this happen!
 
HAVE WE GOT YOUR ATTENTION? WANT TO LEARN MORE?
 
Read about us here! (spoiler alert... we are the home of The Weather Network )
 
Proud to share that we ranked #5 Most Admired Company in Canada in Leger's 2026 Reputation Study, among 334 organizations
 
 
WHY WE NEED YOU? GLAD YOU ASKED...
 
The Software Developer, Meteorological Development is responsible for designing, developing new features, enhancements and services for the meteorological platforms that powers The Weather Network, MeteoMedia, ElTiempo.es, and subsidiaries.  The systems must have high availability, fast response times and scalability to support 4 billion global locations with high quality data.  Are you up for the challenge?

In this role, the successful candidate will work closely with technology and business teams to define and implement functional requirements for meteorological applications and services. Working within an Agile development environment, the developer will build and maintain backend systems written in C/C++, Go, Python, and Rust while solving complex technical and algorithmic challenges associated with processing and distributing large-scale weather data. These services are deployed and running under Kubernetes (EKS), ECS clusters and EC2 instances. Development of these distributed applications and microservices within Linux environments uses technologies including Docker, Kubernetes, Istio, HTTP/gRPC services, Redis, and cloud-native architectures. 

Background in meteorology is a "nice to have", but if you don't, don't worry you will be working closely with our Meteorology R&D team and have the support of the current development team. 

The developer will participate in requirements analysis and help design, implement, integrate, test, document and deploy backend meteorological systems and processes. The developer will also provide professional technical support and be well-versed in SDLC and building robust, high performance systems. 

 
Please note this is a contract role until February 2027 and we are only considering candidates who are eligible to work in Canada and can work in a Hybrid model at our Oakville, ON, Canada location. 
WHAT'S THE DAY TO DAY LIKE?

  • Design, implement, and maintain high-performance meteorological software systems using C/C++, Go, Python, and Rust, including backend services, distributed systems, REST and gRPC APIs, and large-scale data processing pipelines. Deploy and operate these solutions in Linux-based, cloud-native environments leveraging Docker, Kubernetes, Istio, Redis, ECS, EC2 instances and other services across AWS and Google Cloud.

  • Implement software solutions pertaining to our Meteorological systems.

  • Work within an Agile software development process.

  • Use AI-assisted development tools and workflows to improve productivity, accelerate delivery, enhance code quality, support troubleshooting, and streamline operational tasks while maintaining quality and accountability.

  • Work with Technology Operations team to ensure end-to-end data monitoring in software design, from data acquisition to delivery.

  • Use knowledge of databases and database technology to create applications which are distributed, multi-tier, and able to service large volumes of data.

  • Perform unit testing, integration testing, and other automated testing; work closely with QA team to address defects as they arise to ensure production of high quality software.

  • Architect designs for reuse, scalability, flexibility and customizability.

  • Work with Technology teams to continuously analyze in-house software systems, identify weaknesses and propose changes for improvement.

  • Provide support to our operational teams for the relevant production systems. 

Roles, responsibilities and duties may evolve and change over time.

WE ARE HOPING YOU HAVE

  • Degree or diploma in Computer Science, Mathematics, Engineering, or equivalent practical experience.

  • Minimum 5 years of experience in enterprise software development.

  • Strong experience developing and supporting production microservices using Go as primary language, with experience in C/C++, Rust and Python considered an asset.
