Role
Who you are
- You hold a master's or PhD degree in computer science, a related field, or equivalent practical experience
- You have 5+ years of experience with software development in one or more programming languages, and data structures or algorithms
- You're at ease with designing, analyzing, and troubleshooting large-scale distributed systems
- You have experience working in computing, distributed systems, storage, or networking
- You are used to debug, optimize code, and to automate routine tasks
- You show a systematic problem-solving approach, coupled with effective verbal and written communication skills
What the job involves
- The concept of Product Reliability Engineering (PRE) draws inspiration from the principles of SRE. At Criteo, PRE acts as the bridge between Product, Platform Engineering and Infrastructure. The PRE group comprises nine global engineering teams helping R&D design, build, and operate large-scale distributed systems reliably and efficiently
- The common objective of the PRE teams is to build the most reliable platform in AdTech
- As a Senior Software Engineer - Site Reliability Engineer, you'll work closely with product engineering to improve the reliability of our apps, systems and pipelines and assess where optimization is needed most
- You'll tell stories with meaningful monitoring and hopefully never be paged on your on-call rotation because we've worked hard with dev teams to make our platform the most reliable in AdTech. Speaking of on-call; with a group of 5 you're looking at only around 10 weeks in a year, and your time is compensated! Not bad, right?
- You'll learn skills from other team members along the way and have opportunities to teach us! It's perfect for an engineer who likes shipping code and wants to be involved in all aspects of reliability, efficiency & maintainability
- Engage in and improve the whole lifecycle of services - from inception and design, through to deployment, operation, and refinement
- Support services before they go live through activities such as system design consulting, developing software platforms and frameworks, capacity planning, and launch reviews
- Scale, automate, and evolve systems by pushing for changes that improve reliability, efficiency and performance
- Optimize and maintain services once they are live by measuring and monitoring availability, latency, and overall system health
- Practice incident response and blameless postmortems
- Stack: .NET Core, C#, Java/Scala/JVM, Python, Prometheus, Grafana, Kibana, Linux, Kubernetes, Mesos, and more
Our take
Commerce marketing is a huge business with billions spent every year on adverts. And companies that help businesses create and deliver more targeted adverts can command a lot of value. Criteo is one such company operating in this space.
Criteo is a personalised retargeting company connecting marketers and media owners through its Commerce Media Platform, delivering richer consumer experiences. Criteo uses machine-learning technology and data to drive performance, helping marketers and media owners reach their goals.
As marketers are increasingly looking for commerce media solutions, Criteo is operating in a sought-after space. Further, around 73% of media owners seek to optimise media performance as a way to both generate awareness and drive revenue, meaning the company has a significant potential client base. Criteo has continued to make headway here, driving 5 billion ads per day, and is well set to see further adoption of its platform.
