Join OLX and see how far you can go.

Join one of our cross-functional teams in Motors, Real Estate, OLX Classifieds or Platforms, working remotely from Poland. As part of our 1,000+ tech team across multiple locations, you’ll collaborate with engineers, SREs, and product teams to build scalable, high-impact solutions, while reporting to an Engineering Manager who will support your growth and impact. We use Golang and Kotlin, modernizing systems as we transition from legacy PHP and move towards a microservices architecture, deploying through GitLab CI/CD to AWS. If you're passionate about solving technical challenges and scaling cloud systems with AI as part of your daily workflow, we’d love to hear from you!

Who we are looking for:

• Someone who embraces a “you build it, you run it, you own it” mindset — including for AI-generated output: you validate, refactor, and take full accountability
• An engineer with solid experience in software development, ideally with Golang, Java/Kotlin, or PHP
• Someone with experience in relational and non-relational databases (MySQL, DynamoDB, Redis, Memcached) and a good grasp of AWS and Infrastructure as Code (Terraform, CloudFormation)
• A problem solver who approaches challenges with both a technical and user-first mindset to build impactful solutions
• You write structured prompts for multi-step tasks and maintain project-level AI context (CLAUDE.md / rules files) — you catch bugs and gaps in AI-generated output before it lands in production
• You demonstrate measurable judgment about when to use AI and when to override it — you use AI for debugging, performance analysis, and complex refactoring while owning the outcome
• A team player who is open to discussions, cross-team collaboration, and knowledge sharing

What you will be doing:

• Contribute technically to projects and take part in the planning, execution, and success of complex technical tasks
• Be an integral part of the team — establish credibility through the quality of your own and your team’s technical execution
• Use AI to accelerate delivery: delegate routine implementation, generate tests and documentation, and apply AI to debugging and refactoring — while owning every line that ships
• Ask questions, brainstorm, and own the product you’re building
• Work closely with product management to ensure you’re building the best products for users

Our Hiring Process:

• Recruiter Interview
• Engineering Manager Interview
• Live Coding
• System Design

Our benefits

• Monthly salary and an annual bonus (15%)
• Training and conference budget, and free access to Udemy courses
• A benefits package with 300 points on the Mybenefit platform per month, private medical care provided by Luxmed, Ask Henry services, and much more
• IP rights’ costs - 80%
• 100% remote work (as well as the possibility of working from our offices in Poznan and Warsaw)
