With the largest, most powerful source of TV data, Samsung Ads delivers reach that scales and drives results. 

AdGear, is building a next generation ad platform for the new era of digital marketing. Our teams in Canada, the USA and Asia are working in close collaboration to develop a powerful end-to-end cross-media buying platform that will reinvent digital display advertising.

What makes this job meaningful?

We have an exciting opportunity for an experienced, high performing software engineer to join our core engineering team. You’ll work alongside our Chief Architect, Product Managers, and Engineering Managers. You’ll contribute to architecture decisions, mentor and level up engineers.


As a Senior Application Engineer & Architect, you will be working with the Samsung Ads Product and Engineering teams to ensure that that platform as a whole, and its key individual components, are built to operate at high performance, availability and maintainability standards.  You will be key in proposing and driving the vision and approach for updating key web applications and building new components, documenting the architecture at various granularities, and guiding and supporting the development, acceptance and productionization.

Relevant advertising industry experience is useful, but ultimately less so than your demonstrated abilities and attitude. 

Why You’ll Be Motivated To Apply…

  • Lead a re-architecting effort of a large Ruby on Rails monolith application to nimbler components, using a mix of soft logical constraints, hard microservice splits, and other approaches
  • Architecting new components and systems based on internal requirements, with appropriate mix of top-down declaration and bottom-up collaboration
  • Re-architecting existing components to address growth/performance/scalability challenges, including migration and change management
  • Analyzing and constructively critiquing architectures and designs by peers
  • Research and evaluation of best-of-breed technologies to inform architecture decisions, especially build-vs-buy and cost/benefit analysis
  • Maintaining up-to-date architecture documentation and flows as it relates to components, data, and their interdependencies
  • Providing consultancy and guidance to engineering teams as they build and/or evaluate components
  • Provide consultancy during component testing and productionization to ensure fidelity against agreed-on architecture and acceptance criteria
  • Providing consultancy and guidance to non-engineering teams, such as product, privacy and governance, regarding component and data behaviors and characteristics
  • Participate in internal training to improve knowledge of both existing components and general architecture best-practices

  • Strong experience with modern browser-facing technologies (HTML, CSS, JavaScript, React, Web Components, Web Sockets)
  • Strong experience designing APIs (GraphQL preferred), including safety, change management, effective versioning and depreciation
  • Strong experience with microservice architectures, especially if consolidated into a single unified web-facing view
  • Strong expertise across broad computer science fundamentals: Hardware, operating systems, software, data structures, and networking
  • Exceptionally strong communicator, especially in ability to discuss low-level engineering-facing details and high-level product-facing attributes
  • Comfortable presenting and obtaining consensus using multiple methods: Written diagrams and text, in-person meetings, in-person and remote presentations, including occasional cross-office travel
  • Hands-on experience and comfort with classical Software Development Life Cycle
  • Hands-on experience with modern SDLC tooling including source control, reviewing, CI and CD
  • Extremely high level of attention to detail
  • A “can-do” attitude  
  • You have a track record of making things better, questioning and improving the status quo
  • You enjoy working with others who are smart and passionate about building useful, reliable, performant products
  • Demonstrated ability to prioritize tasks and resolve problems in a timely manner
  • Ability to work autonomously, multi-task and work in a fast-paced environment
