We focus on solving real customer problems, not just shipping features. We work in small, high-trust teams, with full ownership across the lifecycle, from design to production and beyond.\nWe value:\nOwnership - engineers own what they build end-to-end\n\nSimplicity - we break down complex problems into clear solutions\n\nThinking Big - we innovate with modern technologies (LLMs, AI Agents, etc.) to solve meaningful problems\n\nQuality - scalable, maintainable systems are non-negotiable\n\nSpeed & iteration - we ship fast, learn, and improve continuously\n\nCollaboration - we win as a team, not as individuals\n\nPosition Overview\nAs a Staff Engineer, your role is to improve the system as a whole, both technically and organizationally.\nYou will work on ambiguous, high-impact problems, shape technical direction across teams, and help others build better systems. Your impact comes less from the code you write, and more from how you influence decisions, design, and execution at scale.\nWhat You Will Do\nTake ownership of complex, cross-team problems that are not clearly defined\n\nDefine technical direction and drive system design across domains\n\nIdentify and address systemic issues and opportunities early\n\nSimplify complexity through better architecture, patterns, and structure\n\nImprove how teams build by raising standards, tooling, and practices\n\nMentor engineers and contribute to hiring and team growth\n\nEnsure systems are reliable, scalable, and built for long-term evolution\n\nWhat Good Looks Like\nYou focus on high-leverage problems and shape how they are approached\n\nYou create clarity in ambiguous situations and align teams around it\n\nYou improve not just code, but how teams design and build systems\n\nYou make others more effective through guidance, feedback, and direction\n\nYou operate with long-term thinking, balancing today’s needs with future scale\n\nYou adopt emerging AI technologies and create a culture of innovation in your teams\n\nAt this level, you are expected to “make the whole system, and the people in it, better.”\nWhat We’re Looking For\nStrong experience designing and operating scalable backend systems\n\nProven ability to work on ambiguous, high-impact problems\n\nTrack record of influencing technical decisions beyond your team\n\nAbility to balance speed, quality, and long-term maintainability\n\nExperience mentoring engineers and improving team practices\n\nFostering a culture of curiosity and experimentation\n\nAPI Documentation\nFor engineers, API design and structure are an important part of evaluating a role. You can explore our API and how we build products here: https://docs.fonoa.com/\nTech Stack\nWe use these technologies today, but we don’t hire for specific tools. We care about engineers who can understand problems, make good technical decisions, and choose the right tools for the job.\nBackend: Node.js, Go\n\nFrontend: React, TypeScript\n\nInfrastructure: GCP, k8s, Terraform, Postgres\n\nNote: \nIf you don’t think you have the full experience we’re looking for, but you could be a fit and are willing to learn, do apply anyway! We are building a diverse and inclusive team.\nAs part of the recruitment process at Fonoa, we process your personal data in accordance with our Privacy Notice for Job Applicants. This notice explains how and why your data is collected and used, and how you can contact us if you have any concerns.","description_format":"text","description_chars":3440,"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":[]},"benefits":[],"hiring_locations":[{"name":"Croatia","iso":"HR","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Accounting & Tax Software"],"lifecycle":[{"event":"open","at":"2026-08-26T13:20:35Z"}],"visa":[],"liveness":{"score":74,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.824,"p_room":0.9,"age_days":50,"expected_fill_days":90,"reasons":["conf:3","win:mid"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/fonoa-senior-software-engineer","json_url":"https://alion.io/job/fonoa-senior-software-engineer.json","meta":{"generated_at":"2026-10-16T10:01:42Z","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":8363,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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":56827},"rest":"https://alion.io/mcp/rest/get_company?id=56827"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffonoa-senior-software-engineer"},{"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%2Ffonoa-senior-software-engineer"},{"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%2Ffonoa-senior-software-engineer"},{"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/fonoa-senior-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffonoa-senior-software-engineer"}]}
