We offer mainframe-like performance, reliability, and security for hyperconverged infrastructure and services while dramatically lowering overall cost and complexity. Our team combines deep engineering expertise with a relentless focus on performance, scalability, and innovation. We pioneered container-based virtualisation technologies and actively contribute to foundational OSS projects such as OpenVZ, Linux kernel, Kubernetes, CRIU, KVM, OpenStack, and more.\nThe Role\nLead Virtuozzo's powerhouse engineering team crafting Virtuozzo Infrastructure System. Guide the development of distributed storage, virtualisation, cluster orchestration, high availability, VM management, monitoring, and seamless updates through UI and REST APIs. As a player/coach, you'll mentor top talent, drive technical excellence, and deliver features that scale to millions-perfect if you love leading complex projects while staying close to the code.\nKey Responsibilities\nLead a team of 5-10 senior engineers: set vision, prioritise roadmaps, and foster a high-performance culture.\nArchitect major features for cluster lifecycle, HA systems, and performance optimisation; contribute hands-on code as needed.\nChampion code quality by overseeing automated testing strategies, CI/CD pipelines, and technical debt reduction.\nCollaborate with product, QA, and support teams to resolve production issues and evolve the platform based on customer feedback.\nMentor engineers on best practices in Linux systems, networking, and distributed design; conduct code reviews and grow talent.\nRequired Skills & Experience\n5+ years in software engineering with 2+ years leading teams.\nExpert in Python, Rust, Go, or C/C++ for production systems.\nAuthoritative knowledge of Linux kernel architecture (e.g., NUMA, scheduling, I/O) and networking (SDN, TCP/IP stacks).\nProven track record of guiding distributed systems projects; strong problem-solving to unblock teams on tough challenges.\nLeadership chops: experience mentoring, running agile processes, and delivering under deadlines.\nPreferred Skills (Standout Plus)\nDeep experience with hypervisors (KVM), containers (Docker/Podman), Kubernetes, or distributed storage.\nBackground in system programming, kernel internals (Linux/Windows/FreeBSD), or fault-tolerant architectures.\nProficiency in automation (Ansible, Bash, Terraform) and cloud platforms (AWS, Azure, GCP).\nWeb development for UI/REST (JavaScript, HTML/CSS); bonus for performance tuning and observability tools.\nWhat We Offer\nRemote and flexible working hours (team is in Europe)\nB2B contracting friendly\nProfessional growth: training budget, certification support, mentorship, and career progression pathways\nInclusive, multicultural team: work alongside talented engineers from across the globe on infrastructure-grade cloud products\nEmployee/Contributor perks: recognition programmes, referral bonuses, and learning initiatives, reward programs\nShare Options- shares in our success with share options","description_format":"text","description_chars":3194,"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":["Flexible schedule","Stock options"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Cloud Platforms (IaaS & PaaS)","Virtualization & Containers"],"lifecycle":[{"event":"open","at":"2026-11-13T19:08:28Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":40,"reasons":["conf:1","win:early"],"computed_at":"2026-11-13T20:09:42Z"},"pay":null,"html_url":"https://alion.io/job/onapp-team-lead-in-software-engineering","json_url":"https://alion.io/job/onapp-team-lead-in-software-engineering.json","meta":{"generated_at":"2026-11-13T20:09:42Z","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":40180,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-14T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":2128220},"rest":"https://alion.io/mcp/rest/get_company?id=2128220"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fonapp-team-lead-in-software-engineering"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Fonapp-team-lead-in-software-engineering"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fonapp-team-lead-in-software-engineering"},{"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/onapp-team-lead-in-software-engineering\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fonapp-team-lead-in-software-engineering"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4276376}},{"tool":"search_jobs","arguments":{"company":"onapp.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4276376},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people);
