OLX is the world’s leading classifieds platform in high-growth markets. It’s available in more than 35 countries and in over 50 languages. The platform makes it so easy to connect people to buy, sell or exchange used goods and services. It’s completely free, it can be done from a laptop or mobile phone. Every month, hundreds of millions of people use it to find and sell furniture, musical instruments, cars, houses and more.  

We’re looking for a software engineer who will be responsible of development of our application back-end. While having all the perks of being part of OLX Group, we operate in startup mode, developing a new product from scratch in a small, autonomous team. While the technology stack is largely up to us, we favor node.js or Go, deployed to AWS as Lambda functions. Our front-end is built using React and Redux.

What you will be doing:

  • working in a small, cross-functional team of about 5-7 people (product, data engineering, front-end, back-end, DevOps)
  • working on a new product, built from scratch
  • developing the back-end of our application, and contribute to other parts of the application (product, front-end, deployment) where possible
  • have impact on the direction of the product, not just the technology side (a sense of ownership is not only allowed, but expected)
  • work in a lean startup, experiment-driven manner, and participate in the design of such experiments.

We’re looking for someone who:

  • has senior-level experience with any back-end technology. Experience with either node.js or Go is prefered, but not required — if you’re the candidate for us, you will pick up these technologies quickly, or convince us we should be using something else
  • has experience working with relational databases as well as non-relational databases, e.g. MySQL, DynamoDB, Redis, memcached
  • has a good understanding of cloud architecture, ideally AWS. Bonus points for experience with DevOps technology like Terraform
  • is able to think from a user perspective — it's important not only to know how to solve a technical problem, but also to understand why
  • bonus: knowledge and/or strong interest in machine learning technologies

Our technology stack:

Largely this to be shaped by whoever joins our team in this role, but our current preferred stack looks as follows:

  • Back-end technology: Node.js, Go
  • Deployment: AWS Lambda (Serverless framework), Terraform
  • Database: MySQL, DynamoDB

What we’ll give you:

  • salary: 10000-14000 PLN gross
  • annual bonus: 15%
  • unique opportunity to become a part of an international team of top engineers learning from one another and contributing to the global OLX success, based in Poznań
  • working with and impacting all OLX websites around the world
  • training and conference budget
  • benefit package
  • relocation support
  • opportunity to work in a best office in Poznan


What you need to know about us:

  • OLX is the world’s leading classifieds platform in growth markets. It’s available in more than 35 countries and in over 50 languages
  • OLX is part of the OLX Group, a global product and tech company with 17 brands, +40 countries, +4000 people and one mindset
  • our mission is to make it easier for people to buy and sell almost anything, promoting prosperity in local communities
    we are proud to be different, and we work differently too. We combine the spirit and agility of a start-up with the maturity that comes from being part of a 100 year-old company
  • we are curious, ambitious and allergic to corporate interference. We improvise, experiment and push each other further, embracing uncertainty and driving change
