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 Screen\nManagement Capabilities\nSystem Design\nLive Coding\nOur Benefits\nMonthly salary and an annual bonus (20%)\nTraining and conference budget, and free access to Udemy courses\nA benefits package with 500 points on the Mybenefit platform per month, private medical care provided by Luxmed, Ask Henry services, and much more \nIP rights’ costs - 80%\n100% remote work (as well as the possibility of working from our offices in Poznan and Warsaw)","description_format":"text","description_chars":4292,"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":[],"hiring_locations":[{"name":"Poland","iso":"PL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Marketplaces"],"lifecycle":[{"event":"open","at":"2026-10-14T12:24:42Z"}],"visa":[],"liveness":{"score":10,"band":"cold","label":"Long shot","p_open":1,"p_active":0.355,"p_room":0.28,"age_days":98,"expected_fill_days":26,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-14T17:19:10Z"},"pay":null,"html_url":"https://alion.io/job/olx-staff-backend-software-engineer-remote-poland","json_url":"https://alion.io/job/olx-staff-backend-software-engineer-remote-poland.json","meta":{"generated_at":"2026-10-14T17:19:10Z","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":22170,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"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-poland"},{"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-poland"},{"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-poland"},{"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-poland\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Folx-staff-backend-software-engineer-remote-poland"}]}
