[Hiring] AI-native Staff Backend Software Engineer @OLX

Role Description

Join Our Team as an AI-native Staff Backend Engineer! Join one of our cross-functional teams in Motors, Real Estate, OLX Classifieds, or Platforms, working remotely from Portugal.

Are you someone who is craving scalable problems and dealing with optimizations? You'll work with a creative, critical, and well-organized team from the comfort of your house, but as close as we have ever been! You will play a key role in enabling our organisation to scale efficiently.

Qualifications

• Ability to use agentic workflows (Claude Code, Cursor Agent, or equivalent) as your default.
• Practice context engineering, designing the full information architecture an AI agent needs to succeed.
• Understand model routing trade-offs (e.g., Haiku vs. Sonnet vs. Opus) and multi-agent orchestration.
• Strong ownership instinct: AI output is a first draft; you validate, refactor, and take full accountability.
• Strong coding and computer science fundamentals.
• Experience in Golang, Java/Kotlin (preferred technologies), and PHP.
• Flexible and capable of adjusting to changing project requirements, roles, and backend technologies.
• Expertise in scalable systems, large-scale web applications, and economic-thinking mindset.
• Deep expertise in scalable distributed systems, CI/CD, RESTful and GraphQL APIs, AWS, and relational + NoSQL databases.
• Big-picture thinker: aligns technical decisions with business strategy, influences without authority.
• Clear communicator in English across engineering, product, and leadership audiences.
• Self-starter who identifies what needs doing and takes initiative without waiting to be asked.
• Skilled Technical Leader and Mentor: Guide and support engineers by setting a strong example.

Requirements

• Architect context pipelines for AI agents to produce reliable, mergeable code.
• Prepare task specifications that are agent-actionable with clear acceptance criteria.
• Design and maintain agent-ready systems with comprehensive test suites and CI/CD pipelines.
• Serve as an AI Champion, contributing to workshops and mentoring engineers on AI-assisted practices.
• Drive migration from a legacy monolith to microservices, owning decisions on bounded domain decomposition.
• Set the bar for GraphQL API design, RESTful contracts, database schema, and CI/CD quality.
• Work with product and engineering leadership to identify high-value problems and propose initiatives.
• Guide senior engineers in managing and reducing technical debt with AI as an accelerator.

Benefits

• Permanent contract.
• Salary + annual bonus up to 20% of your annual gross salary.
• Work with and impact all OLX websites around the world.
• Train and conference budget, and free access to Udemy courses.
• Health insurance and life insurance.
• MacBook Pro or a Windows Dell, along with necessary accessories.
• 100% remote work (and the possibility to work from our office in Lisboa).
