Staff backend software engineer - remote (portugal)

Sobre a vaga

Join one of our cross-functional teams in Motors, Real Estate, OLX Classifieds, or Platforms as an AI-native Staff Backend Engineer. You will play a key role in enabling our organisation to scale efficiently by dealing with optimizations and scalable problems.

O que vais fazer

• Architect context pipelines for AI agents: curate what enters the context window (repo boundaries, domain knowledge, test outputs, CI feedback) so agents produce reliable, mergeable code, not just plausible code
• Prepare task specifications that are agent-actionable (clear acceptance criteria, referenced modules, explicit constraints)
• Design and maintain agent-ready systems: well-bounded repos, comprehensive test suites as guardrails, CI/CD pipelines with structured output agents can parse and act on
• Serve as an AI Champion: join and strengthen our growing 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
• Working on making agentic workflows effective across a codebase whose boundaries are actively being redefined
• Set the bar for GraphQL API design, RESTful contracts, database schema, and CI/CD quality across the tribe
• Work with product and engineering leadership to identify high-value problems, propose initiatives, and drive impactful technical direction without direct authority
• Guide senior engineers in managing and reducing technical debt with AI as an accelerator, not a shortcut

O que é pedido

• You can use agentic workflows (Claude Code, Cursor Agent, or equivalent) as your default, not as a novelty
• You practice context engineering, not just prompt engineering; you design the full information architecture an AI agent needs to succeed: repo structure, CLAUDE.md / AGENTS.md configs, relevant code context, memory, and tool access
• You understand model routing trade-offs (e.g., when to use Haiku vs. Sonnet vs. Opus) and multi-agent orchestration
• Strong ownership instinct: AI output is a first draft, not a deliverable; you validate, refactor, and take full accountability
• You have strong Coding and Computer Science Fundamentals
• Strong background experience in Golang, Java/Kotlin (preferred technologies), and able to work with PHP
• Flexible and capable of adjusting to changing project requirements, roles, and backend technologies as needed
• Scalable Systems Expertise
• Experience with large-scale web applications, an economic-thinking mindset, and being able to design well-bounded future-proof domain systems, aligned with the 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 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

O que é oferecido

• 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 the necessary accessories to make your work comfortable
• 100% remote work (and the possibility to work from our office in Lisboa)
