This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Software Engineer II - Ads Manager (Front End) based in Canada.
As a Senior Frontend Software Engineer, you will lead the technical evolution of a sophisticated advertising management platform used by brands, agencies, and retailers to create, manage, and optimize digital campaigns. You will shape the frontend architecture, drive major engineering initiatives, and build scalable, high-performance interfaces that simplify complex advertising workflows. Working with React, Node.js, and modern web technologies, you will develop campaign management tools, reporting dashboards, and reusable design system components. You will collaborate closely with Product, Design, Backend, and Data Science teams to deliver impactful user experiences and strengthen platform reliability. Beyond hands-on development, you will influence technical strategy, improve engineering productivity, and mentor fellow engineers. This role offers the opportunity to lead large-scale frontend initiatives while exploring innovative AI-assisted development practices.
Accountabilities:
You will own the frontend technical direction and contribute to the long-term evolution of the advertising platform, balancing architectural excellence with product delivery and business priorities. Your responsibilities will include:
Lead the frontend technical roadmap and architecture, ensuring web applications remain scalable, maintainable, extensible, and aligned with long-term product objectives.
Design, develop, and maintain high-quality React applications supporting campaign creation, management, reporting, and optimization.
Define and improve shared frontend components, state management solutions, and reusable abstractions to accelerate development and maintain consistency.
Partner with backend engineers to establish robust API and data contracts that support reliable, observable, and cost-efficient systems.
Collaborate with frontend engineering leaders and technical peers to establish consistent engineering standards, architectural patterns, and development best practices.
Champion application performance, observability, and reliability through effective metrics, logging, tracing, and operational readiness for critical user workflows.
Drive technical modernization initiatives, including legacy code migrations, architectural refactoring, and technical debt reduction.
Integrate security-by-design principles into frontend architecture and lead responses to significant security or reliability incidents affecting the platform.
Lead strategic team-wide and cross-functional engineering initiatives, aligning stakeholders and coordinating execution across multiple teams.
Work closely with Product and Design teams to deliver intuitive, accessible, and high-quality user experiences.
Mentor and support engineers up to the L5 level through technical coaching, onboarding improvements, knowledge sharing, and professional development.
Identify and resolve cross-team execution challenges while improving engineering collaboration and delivery practices.
Define and promote best practices for AI-assisted development tools, including their application to coding, testing, refactoring, and developer productivity.
Requirements:
You are an experienced frontend engineering professional with a strong track record of building complex web applications and leading large-scale technical initiatives. You combine deep expertise in modern frontend technologies with architectural judgment, cross-functional leadership, and a passion for improving engineering practices. The ideal candidate will bring:
At least 8 years of experience building modern web applications, with significant ownership of complex, user-facing products.
Advanced proficiency in Node.js and React, including hooks, state management, performance optimization, and development within large codebases.
Strong frontend architecture expertise, including modularization, shared component libraries, routing, data fetching, and error-handling strategies.
Experience designing and integrating REST and/or GraphQL APIs in close collaboration with backend engineering teams.
A proven ability to lead complex, ambiguous, multi-stakeholder projects from initial design through implementation, rollout, and ongoing operations.
Demonstrated impact on engineering productivity and code quality through reusable abstractions, developer tooling, automated testing, and CI improvements.
Experience with web application monitoring and observability platforms such as Datadog or similar tools.
Familiarity with AI-assisted development tools and an interest in introducing scalable practices that improve team productivity.
Excellent communication and collaboration skills, with the ability to work effectively with engineers, Product Managers, Designers, and other stakeholders.
Additional experience that would be considered an asset:
Experience building large-scale, data-intensive user interfaces, including analytics dashboards, editors, and complex workflow applications.
Hands-on experience with GraphQL at scale, including schema design, client-side patterns, and performance optimization.
Familiarity with automated testing frameworks such as Selenium, Cypress, or Playwright.
Deep knowledge of frontend performance and reliability practices, including bundle optimization, code splitting, and application resilience.
Experience leading major modernization initiatives, framework upgrades, design system adoption, or legacy application migrations.
Familiarity with design and collaboration tools such as Figma.
A strong track record of mentoring L3–L5 engineers and serving as a technical expert for a product domain or platform area.
