Job Description

The team:
The First Party Advertising technology team (iCAS) is looking for a Machine Learning / Data Engineer to strengthen the team. We are building an internally used advertising engine combined with seller tools, to deliver shopping listings to the multiple platforms we have within Adevinta. Some of our complexities is the high traffic and volume demand, high uptime, handling click-fraud and optimising the listings being shown.

We do this through a technology stack mainly running through Go-lang based microservices, with eventing on Kafka, reporting on Clickhouse and Datastorage on MySQL. We run these services through Nomad on our own private cloud, and we handle the dev-ops activities such as deployment (Github, Jenkins), uptime (lot's of 9s), monitoring (Prometheus, Pagerduty, Grafana) and maintenance as well. Our frontend is based on NodeJS and Knockout. This stack is in constant evolution and flux to support growth as well as our own efficiency

Some numbers:

  • Up to 10K events per sec per service.
  • System handling up to 5000 searches per second.
  • Over 10m live Listings
  • Serving the biggest classifieds sites in CA, DE, NL and BE
  • End-to-end ownership of the seller's journey, from the shop around the corner to big retail brands


What you’ll do:
Your initial role in the team is to help in-house an externally developed auction simulation and auto-bidding engine based on Reinforcement Learning (Soft Actor Critic). You will take the lead on moving this from Proof-of-concept to fully integrated into our main product and infrastructure, together with the rest of the team of Backend and Devops Engineers (Go-based). Long term our goal is to expand on our Machine Learning infrastructure, as well as explore new venues on machine learning (either iterations or new possibilities).

If you are a good practical data engineer with affinity in both maintaining machine learning infrastructure and model development, come work for us! You won't regret it.

Qualifications

Who you are:

  • BS/BA level of thinking and cooperation
  • Experience with Machine Learning on large datasets.
  • Experience with Software/Data Engineering on large data sets
  • 4+ years of work experience in the field of data engineering/machine learning
  • Proficient in Software Development (Python at least, lower-level languages are a pre)
  • Willingness to both teach others and learn new techniques. Good leadership and communication skills.
  • Participate in the on-call rotation together with the rest of engineering (we run what we build)
  • A can-do attitude (sarcasm is allowed) and drive to solve problems for our partners and customers

Additional Information

What you’ll get from us:

  • Opportunity to shape the way we work. Your feedback and opinions are valued at all levels of the organisation
  • Benefits including stock purchase plan and annual bonus plans
  • Flexibility to work when and how you want - flexible hours, autonomy to set your own agenda, choice of phone and computer
  • Smart Working Policy - work remotely some of the time, balanced with time in the office together with your team - between 5 and 45 days per quarter in the office depending on each team.
