Roughly ⅔ of your time will be hands-on technical work: designing solutions, steering and reviewing AI-generated code, developing new ideas, and reviewing others' contributions. The rest goes to cross-team influence, mentoring, and strategic alignment.\n\nStrong 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.\n\nScalable 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.\n\nDeep expertise in scalable distributed systems, CI/CD, RESTful and GraphQL APIs, AWS, and relational + NoSQL databases.\n\nBig-picture thinker: aligns technical decisions with business strategy, influences without authority.\n\nClear communicator in English across engineering, product, and leadership audiences.\n\nSelf-starter who identifies what needs doing and takes initiative without waiting to be asked.\n\nSkilled Technical Leader and Mentor: Guide and support engineers by setting a strong example. As a Staff Engineer, you are a role model, leading by example and through your expertise.\n\nWhat you will be doing:\nArchitect 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.\n\nPrepare task specifications that are agent-actionable (clear acceptance criteria, referenced modules, explicit constraints)\n\nDesign 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.\n\nServe 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.\n\nDrive 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.\n\nSet the bar for GraphQL API design, RESTful contracts, database schema, and CI/CD quality across the tribe.\n\nWork with product and engineering leadership to identify high-value problems, propose initiatives, and drive impactful technical direction without direct authority\n\nGuide senior engineers in managing and reducing technical debt with AI as an accelerator, not a shortcut.\n\nOur Hiring Process:\nRecruiter Interview\n\nManagemnent Capabilities\n\nSystem Design\n\nLive Coding\n\nOur Benefits\nPermanent contract\nSalary + annual bonus up to 20% of your annual gross salary\nWork with and impact all OLX websites around the world\nTrain and conference budget, and free access to Udemy courses\nHealth insurance and life insurance\nMacBook Pro or a Windows Dell, along with the necessary accessories to make your work comfortable\n100% remote work (and the possibility to work from our office in Lisboa)","description_format":"text","description_chars":4333,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"Upper-Intermediate (B2)","optional":false}]},"benefits":["Apple Macbook","Health insurance","Life insurance"],"hiring_locations":[{"name":"Portugal","iso":"PT","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Marketplaces"],"lifecycle":[{"event":"open","at":"2026-10-14T12:24:42Z"}],"visa":[],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.182,"p_room":0.28,"age_days":197,"expected_fill_days":43,"reasons":["conf:0","stale_co","velocity","win:tail","crowd:"],"computed_at":"2026-10-22T06:10:10Z"},"pay":null,"html_url":"https://alion.io/job/olx-staff-backend-software-engineer-remote-portugal","json_url":"https://alion.io/job/olx-staff-backend-software-engineer-remote-portugal.json","meta":{"generated_at":"2026-10-22T09:59:24Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":6995,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-23T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":445577},"rest":"https://alion.io/mcp/rest/get_company?id=445577"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Folx-staff-backend-software-engineer-remote-portugal"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Folx-staff-backend-software-engineer-remote-portugal"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Folx-staff-backend-software-engineer-remote-portugal"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/olx-staff-backend-software-engineer-remote-portugal\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Folx-staff-backend-software-engineer-remote-portugal"}]}
