It helps us move faster, spend less time on repetitive work, and focus on bigger ideas.\nIf you want your work to influence both what we build and how we build it, we'd like to meet you.\nOur culture: Guided by 10 company principles\nYour role at Hostinger\nAs System Engineer, you'll join one of the few places left where a single team owns the whole stack end to end - compute, storage, networking, and the services running on top of it. Email is what makes that infrastructure hard: it's stateful, latency-sensitive, adversarial, and it never stops. You'll join at a point where large parts of the platform are being modernized, so there's genuine architectural work ahead, not just maintenance of someone else's decisions. This isn't a role where you follow playbooks - you'll write them.\nCurious to learn more? Connect with your team: Edgaras Lukoševičius, Engineering Manager, Email Hosting.\nYour day-to-day\nBuild and scale the infrastructure behind the service. Design and operate the systems that carry millions of messages a day - compute, networking, routing, and throughput - at a volume where a fraction of a percent is thousands of clients.\n\nRun storage at scale. Petabytes of customer data across a distributed storage fleet: capacity planning, performance tuning, backups, and data integrity.\n\nAutomate everything you touch. Our infrastructure lives in code. If you did it manually twice, the third time should be a pull request.\n\nEngineer how we ship. Build the testing and deployment pipeline that lets a platform this large change safely - infrastructure tests, preflight checks, progressive rollouts. Confident releases are an engineering achievement, not an accident.\n\nOwn monitoring and observability. Metrics, logs, SLOs, and alerting - build the systems that surface a problem while it's still small, so it's solved before anyone notices it.\n\nFight spam and abuse. Tune the filtering engines, rate limits, and authentication that stand between millions of mailboxes and everyone trying to get into them.\n\nSolve problems at the root. When something surfaces, the interesting question isn't how to close the ticket - it's what change makes that entire class of problem stop happening.\n\nShare what you learn. Review code, write the runbook, explain the failure mode. The team gets stronger, or it doesn't scale.\n\nWhat will help you succeed\nStrong Linux experience (5+ years) - deep and hands-on, not just comfortable at a shell.\n\nOn-prem and cloud. We run most of our systems on our own hardware, with parts in the cloud (GCP, AWS, Cloudflare). We're looking for either a strong on-prem and virtualization background (Proxmox, KVM, bare metal) with cloud exposure, or a strong cloud background with real hands-on on-prem experience.\n\nInfrastructure as Code - Ansible, Terraform, or equivalents. You trust automation, and know how to do it right.\n\nProgramming or scripting in Go or Python (bonus if both). Occasionally Lua or Rust show up too - we're happy to lean on AI for the long tail.\n\nProduction experience with databases, caches, and queues - MySQL, PostgreSQL, Redis/Valkey, Memcached, or similar.\n\nContainers and orchestration - you've experience running workloads on Kubernetes and Docker\n\nStorage fundamentals - filesystems, distributed storage, replication (Ceph or similar) is a plus\n\nNetworking fundamentals - DNS, TCP/IP, TLS, HTTP, and routing.\n\nNice-to-haves\nHands-on experience with an MTA at scale - Postfix, Exim, KumoMTA, GreenArrow, PowerMTA, ZoneMTA, or similar.\n\nExperience running an IMAP/mail store - Dovecot, Cyrus, or equivalent.\n\nSpam filtering and email security tooling - Rspamd, SpamAssassin, or similar.\n\nUnderstanding of email authentication and deliverability - SPF, DKIM, DMARC, ARC, rDNS, blocklists, feedback loops.\n\nExperience with IP reputation, warmup, or high-volume sending.\n\nFamiliarity with data pipeline and analytics tooling - ClickHouse, Kafka/Redpanda, Flink.\n\nCI/CD beyond GitHub Actions, and open-source contributions.\n\nCertifications like RHCSA or RHCE.\n\nMeet your team\nYou’ll join the Email Team. The team owns Hostinger’s entire email platform end to end - inbound and outbound mail delivery, storage, spam and abuse defense, and the automation behind all of it - powering millions of client mailboxes.\nYou’ll work most closely with a tight-knit mix of system engineers, backend and frontend developers, and QA engineers, all building and running the same platform from different angles - infrastructure, product, and quality meeting in the same codebase. Because email underpins so much of the business, the team also works closely with Customer Support on investigating issues escalated by clients, and with Security, Network, Storage, and other infrastructure teams across Hostinger on keeping the platform safe and reliable.\nBenefits you’ll love\n360 Growth: We provide limitless learning opportunities: access to platforms like Reforge and CoachHub, global conferences, physical and digital libraries, feedback culture, and mentoring through TesoXchange. Advance your career with internal mobility and grow with a team eager to share knowledge and support your success.\nFreedom & responsibility: Work on your terms: from modern offices in Kaunas and Vilnius, the comfort of home, or anywhere in the world. Enjoy flexibility in managing your schedule and bring your ideas to life in a fast-paced, dynamic environment.\nWellness simplified: Your health comes first with insurance from Day 1, gym memberships, recharge leave, Headspace subscriptions, and regular health checks. Join our wellbeing-dedicated events, sports, arts, and hobby clubs, or simply enjoy the balance of a lifestyle that prioritizes wellness.\nWork hard - play hard: Celebrate your achievements with company events like Summerfest & Winterfest, Town Hall, Meet the Client initiatives, team-buildings, and workations. Enjoy access to the Žalgiris Arena VIP Lounge and celebrate life’s big moments with milestone gifts for weddings, new parenthood, and graduations.\nCompensation starts from €5,000 gross/month, depending on your experience and skills.\nWe’re always looking for experienced talent to raise the bar. If you’re excited about the role but the listed compensation range doesn’t align with your expectations, we still encourage you to apply - we’re open to adjusting it based on the impact and value you bring.\nGet ready to take your personal and professional growth to new heights!
