Site Reliability Engineer

Located in the heart of Old Montreal, AdGear is an advertising technology startup that is now part of Samsung Electronics. We work on complex technical challenges at an increasingly impressive scale, addressing hundreds of millions of devices across the world.  Being part of an international company and doing business around the world means that we get to work on big, complex projects with stakeholders and teams in Silicon Valley, Korea and Europe.

As our infrastructure and business continue to grow, we are looking to expand our SRE team. 

What you’ll do

The AdGear Site Reliability Engineer is a software engineer responsible for ensuring that the AdGear platform's services are designed, implemented, deployed, and operated such that they are highly available, highly performing, and scalable.

The ideal candidate for the Site Reliability Engineer position typically self-identifies as a "hacker", who is both a "jack of all trades" as well as possesses deep knowledge in multiple areas of software development, Linux/unix systems administration, networking, internet protocols, databases, and distributed systems. The ideal candidate has a mix of software development and infrastructure operations skills, and approaches infrastructure operations from the perspective of a software engineer.
Relevant industry experience is important, but ultimately less so than your demonstrated abilities and attitude.

You will work with some incredibly talented and passionate developers within an engineering team with a strong technological background as well as working in a small team of SREs, supporting a medium-sized team of software engineers working on building the next generation of AdGear's administrative interfaces, ad decisioning, delivery, data processing and analytics systems.
