DATA SPECIALIST (Web Developer)

Job Responsibility: Job ID: 40736 Job Category: Engineering & Technical Division & Section: Transportation Services, Policy & Innovation Work Location: 433 Eastern Avenue, Toronto Job Type & Duration: Full-time, 2 Temporary (12 month) vacancies Salary: $93,500.00 - $119,274.00 Shift Information: Monday to Friday, 35 hours per week Affiliation: Non-Union Number of Positions Open: 2 Posting Period: 03-Nov-2023 to 23-Nov-2023 Job Summary We are seeking two experienced web developers to join the MOVE digital product team. We are hiring for two specialties:

• Backend Web Developer
• Frontend Web Developer

MOVE is an internal web application and data platform used by hundreds of City staff to make sense of vehicle, cyclist, and pedestrian traffic volumes and collisions. Our goal is to empower City staff with data to make better, more proactive decisions so that Toronto's transportation network is safe, efficient, and equitable for all. Building on our success to-date, we're embarking on a rebuild of our web application. We're looking for candidates who are ready to roll up their sleeves and tackle our technical debt, build a more scalable and adaptable web application, and set the technical foundation for future aspirations: a publicly accessible version of MOVE, a platform that can be shared and adapted by other municipalities, and a web application that is ready to handle more transportation data. You will join a data engineer and product manager to own the development and sustainment of MOVE, related digital products, and data platform. We work with modern open source technologies, in the open (on GitHub!), and leverage human-centered design practices to deliver tangible impact to those living in the largest city in Canada. The MOVE digital product team is part of the Transportation Data & Analytics unit, one of the largest public-sector Data & Analytics teams in Canada, established as a hub for data analytics, data science, data collection and data management. VIRTUAL INFORMATION SESSION All interested applicants are invited to attend a virtual information session, where they will have an opportunity to learn more about the Policy & Innovation section, the role and responsibilities of the Data Specialist position.

• Set the technical vision for the web backend, including (but not limited to):
  • Models and server-side query logic to represent geospatial transportation data
  • Integrations for data analysis and statistical summary logic
  • Controller and View logic to serve the data through an API
  • Caching mechanisms to reduce database load and improve application performance
  • Queueing mechanisms for processing jobs and large data or file downloads
  • Security measures such as encryption, authentication, and access control
  • Unit and integration test suite
• Design, implement, and maintain the web backend codebase in a Python web development framework (e.g. Django)
• Create and maintain automated deployment pipelines, ensuring well-tested and reliable deployments to production
• Work closely with the data engineer to review and adapt the backend to proposed changes and new transportation datasets
• Collaborate with technical City stakeholders to establish, manage, and evolve AWS and on-premises application infrastructure, conduct security reviews, and coordinate releases

Frontend Web Developer Responsibilities As a Frontend Web Developer, you'll own the web frontend.

• Set the technical vision for the web frontend SPA, including (but not limited to):
  • View logic, developed using a mature web development framework
  • A dynamic and complex data store

  • A design system to maintain UI/UX consistency
  • Unit and integration test suite
• Design, implement, and maintain the web frontend codebase in a mature JavaScript UI component framework (e.g. React, Vue)
• Lead our frontend design practice, recommend and review information architecture patterns for the application
• Work closely with the product manager to understand user pain points and needs, and implement practical frontend solutions to address them

Common Responsibilities

• Monitor performance, identify and resolve bottlenecks, and suggest optimizations for the web application, data layer, and integrations
• Prioritize and resolve bugs in a timely fashion
• Contribute to technical documentation
• Collaborate with Data & Analytics to turn experimental models and analyses into data products, and own the integration and visualization of these products
• You may be asked to prepare communications:
  • Reports or presentations for City Council, Transportation Services, other Departments/Divisions, conferences, seminars, or events;
  • Liaise (attend meetings, networking events, respond to inquiries) with other levels of government, consultants, contractors, vendors, elected officials, external organizations, and the public.

  • care more about solving problems and building robust, reliable, maintainable solutions than using particular technologies
  • champion modern web development best practices across the organization, to advance the state of in-house product development
  • stay current with new tools and techniques relevant to your discipline (time and budget are available for training and conferences)
  • coach and mentor junior developers and students
