Job Description


We are seeking a highly experienced Senior Java Backend Engineer to join our team. You will play a crucial role in advancing the impact of our AdTech platform and delivering critical projects that bring significant value to operations. As a strong individual contributor, you will design and develop scalable systems, working closely with the architecture team and advising on broad technical decisions that impact our backend tech stack.



This is a hybrid opportunity, working Mondays, Tuesdays, and Thursdays on-site in our downtown Toronto office. Our headquarters are located within minutes of St. Andrew and Union subway stations.



About the Role


This is a unique opportunity to be part of a development team with the autonomy to choose how they work and code, taking ownership of introducing and adopting new tools and executing with excellence. You will have the chance to work with data at scale, driving programmatic traffic globally across all devices, streaming services, and out-of-home targeted advertising.



You will contribute to platform and feature development on a large, distributed system that handles 1.5 million requests per second with 120ms response times. You will design and improve key components, focusing on performance and scalability, while monitoring code to ensure it meets user needs and business goals.



Your Key Responsibilities



  • Design and develop scalable systems, working directly with the architecture team
  • Advise on broad technical decisions that impact our backend tech stack
  • Collaborate across technical pillars and provide expertise to guide junior team members
  • Participate actively in Agile Scrumban practices, breaking down tasks and collaborating in daily stand-ups
  • Prioritize quality and participate in code reviews, analysis, and performance tuning
  • Mentor and grow the team, offering guidance and coaching to junior developers


What We Offer


We offer a comprehensive compensation package, including a salary of $150,000 per year, plus benefits, and a flexible work environment. Our headquarters are located within minutes of St. Andrew and Union subway stations, making it easy to get around the city.



About You


To succeed in this role, you should have experience with Java and Spring, and a deep understanding of building highly available, high-performance systems. You should be skilled in optimizing web application performance across the stack, with hands-on experience in Kubernetes, Docker, and Microservices.



You should be comfortable working with relational databases and key-value stores, proficient in SQL, database schema design, and infrastructure, and familiar with NoSQL databases. Your expertise should also extend to Unix/Linux environments, design patterns, and functional programming, with a working knowledge of networking, concurrency, and Big Data concepts.
