We are at a pivotal moment, evolving into a product-led company with a team of over 100 skilled professionals and new leadership guiding our path forward. By harnessing the power of data, advancing our AI capabilities, and deeply investing in our people, we are preparing for a future that will redefine what’s possible in journey advertising.

Our work is guided by two beliefs: that the ability to execute is paramount to success and that we are only as good as our people. As we grow and transform, we are looking for team members (illumineers) who share our bias for speed, delivery over perfection, and an entrepreneurial mindset. Joining us now is a chance to be part of our transformation. 

Who we need

Reporting to the Director of Infrastructure, Operations, and Security, our growing engineering team is seeking a Database Administrator – MySQL to architect, manage, and optimize our Percona-based MySQL clusters in a high-throughput, ultra-low-latency environment. The successful candidate will demonstrate mastery in query tuning, high availability design, and database automation, supporting mission-critical services without reliance on public cloud infrastructure. You will be responsible for a multi-master, multi-cluster on-prem architecture, ensuring stability, performance, and scalability across all environments.

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

What is in it for you

Impact and influence. As part of a small team within a publicly traded, product-led company, you will play a pivotal role in optimizing our on-premises database systems to add redundancy and resiliency in a multi-data centre environment. You will lead the design and implementation of new management solutions that improve performance, stability, and observability across our infrastructure.

Technical exposure. Our platform processes nearly 150 billion requests daily, driving programmatic traffic globally across all devices, streaming services, and out-of-home targeted advertising. Working with data and infrastructure at this scale is a rare opportunity. This is a chance to apply your expertise in distributed systems, high-throughput database operations, and infrastructure automation to support the evolution of a scalable, real-time AdTech platform.

Professional development. You want to grow your skills, your influence, and your career. We push the limits to improve and to reach our full potential, individually and as a company. We are committed to building the strengths of our team. You will be supported by your manager and have access to one-on-one coaching with our Chief Empowerment Officer team. Your accountabilities, learning opportunities, and scope for ownership and career growth will rapidly expand as we continue to step up to meet the increased value and shifting needs of AdTech.

How you will make an impact

• Troubleshoot. You will diagnose and resolve complex locking, replication, transaction conflicts, and query performance issues under high load. You will identify and address root causes quickly to maintain system stability.
• Manage databases. You will be responsible for the health, maintenance, and performance of our MySQL environments. You will oversee schema migrations, plan and execute backup strategies, and maintain disaster recovery processes to minimize service disruptions.
• Automate. You will script database tasks using Python, Bash, or similar tools to automate routine processes, reduce manual effort, and improve efficiency across environments.
• Monitor. You will proactively monitor database health and performance using PMM and Netdata. You will detect trends, address anomalies, and prevent failures before they impact operations.
• Collaborate. You will work closely with developers to improve schema design and optimize application queries. You will analyze execution plans and indexing strategies to support performance at scale.
• Improve processes. You will maintain and continuously enhance database lifecycle practices across development, staging, and production environments, ensuring consistency and reliability.
• Ensure security. You will enforce security and compliance protocols, including encryption, auditing, and access control. You will ensure all data is protected and handled in accordance with company policy.

What you bring

• The MySQL expertise. You have in-depth experience administering MySQL databases, including Percona Server and XtraDB Cluster.

You have experience with PMM and Netdata for database performance monitoring. You are comfortable working in an on-premise environment with both virtual and physical hardware.
• The extra technical skills. You are familiar with MySQL 8.x features such as invisible indexes, histograms, and CTEs. You may have experience with backup and restore strategies using Percona XtraBackup. You have exposure to ETL processes, time-series databases, or event logging systems. You have a basic understanding of HAProxy or ProxySQL for query routing and load balancing.
• The ownership. You have the ability to review, approve, and offer feedback on plans and designs created by others. You can define runbooks that improve the efficiency of all teams. You have the confidence and technical knowledge to make informed, unilateral decisions in emergencies and under pressure. You are solution-driven and able to identify technical issues that need attention, conducting research to fill your own knowledge gaps. You are skilled at mining information from in-house documentation and the internet.
• The interpersonal skills. You have excellent written and verbal communication skills, enabling you to effectively convey complex data concepts to both technical and non-technical stakeholders. You can build trust and collaborate seamlessly with cross-functional teams, sharing your thought process and adopting constructive feedback. You are helpful and supportive, with a proven ability to guide the technical work of the company, communicating information clearly, and offering expertise as needed.
