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 passionate about scalable problems and optimization challenges?
You will collaborate with a creative, critical, and organized team from the comfort of your home, maintaining close connections.
This key role will enable our organization to scale efficiently.
Who We Are Looking For:
- Proficiency in agentic workflows (Claude Code, Cursor Agent, or equivalent) as a default practice.
- Expertise in context engineering, not just prompt engineering. You design the full information architecture for AI agents, including repo structure, CLAUDE.md / AGENTS.md configs, relevant code context, memory, and tool access.
- Understanding of model routing trade-offs (e.g., Haiku vs. Sonnet vs. Opus) and multi-agent orchestration.
- Strong ownership instinct: AI output is a first draft, requiring validation, refactoring, and full accountability.
- Strong Coding and Computer Science Fundamentals. Approximately two-thirds of your time will involve hands-on technical work: designing solutions, steering and reviewing AI-generated code, developing new ideas, and reviewing contributions. The remaining time will be dedicated to cross-team influence, mentoring, and strategic alignment.
- Strong background in Golang, Java/Kotlin (preferred technologies), and ability to work with PHP. Flexible and adaptable to changing project requirements, roles, and backend technologies.
- Scalable Systems Expertise: Experience with large-scale web applications, an economic-thinking mindset, and the ability to design well-bounded, future-proof domain systems aligned with business objectives.
- 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 direct authority.
- Clear communicator in English across engineering, product, and leadership audiences.
- Self-starter who identifies needs and takes initiative.
- Skilled Technical Leader and Mentor: Guide and support engineers by setting a strong example and leading through expertise as a Staff Engineer.
What You Will Be Doing:
- Architect context pipelines for AI agents: curate context window inputs (repo boundaries, domain knowledge, test outputs, CI feedback) to ensure agents produce reliable, mergeable code.
- Prepare agent-actionable task specifications (clear acceptance criteria, referenced modules, explicit constraints).
- Design and maintain agent-ready systems: well-bounded repos, comprehensive test suites as guardrails, and CI/CD pipelines with structured output for agents.
- Serve as an AI Champion: join and strengthen our AI Champion community, contribute to workshops, curate effective agentic workflows, and mentor engineers on AI-assisted practices. Contribute to org-level AI tooling evaluations and OLX AI practices repositories.
- Drive active migration from a legacy monolith to microservices, owning decisions on bounded domain decomposition. Work on making agentic workflows effective across an evolving codebase.
- Set the standard for GraphQL API design, RESTful contracts, database schema, and CI/CD quality across the tribe.
- Collaborate with product and engineering leadership to identify high-value problems, propose initiatives, and drive impactful technical direction.
- Guide senior engineers in managing and reducing technical debt using AI as an accelerator.
