- What you can expect from us
This is how your week will look like
- There was a problem over the weekend with otherwise smooth operation of our infrastructure . – tens of thousands of our customers count on it! The first thing in the morning you try to uncover the root cause of the problem along with the administrators and ideally solve it in such a way that it will never arise again as tens of thousands of our customers count on it! We keep an internal record of all incidents using JIRA tickets. The goal is to have problem-free systems without the necessity of an intervention.
- Your day today is devoted to actively improving our existing solutions – either those that are in-house or private solutions for our large customers. You educate yourself, train your colleagues, check up on our data centers or, in case of large-scale projects, meet with partners. We expect you to take initiative in devising solutions that would improve the infrastructure and services for our clients. We’ll be happy to support your ideas.
- In most cases, our systems run on the Ubuntu LTS platform managed by SaltStack config management. Our virtual servers run on the OpenStack platform. This is your natural habitat and you are always ready to explain all the technical solutions to your more junior colleagues.
- Your main responsibility will be to develop our infrastructure in a way that response to the dynamic growth of the company, thousands of new customers and support new products.
- Our secret recipe for success you will help to improve is based on:
- webhosting › Ubuntu LTS + nginx, apache, php, MySQL, MariaDB, PostgreSQL, ZFS, LXC, LXD
- mailhosting -> postfix, dovecot, Rspamd, Halon, IceWarp
- cloud -> OpenStack, OpenvSwitch, RabbitMQ, Docker, Docker Swarm, Redis, Galera cluster, gitlab CI
- dns -> KnotDNS, bind, PowerDNS
- the infrastructure is managed via SaltStack, monitored via Zabbix and tied to our systems using Python scripts
What do we expect from you?
- Concepts such as web hosting, web server, virtual server or storage are friends of yours
- You have at least 5 year of experience with managing Linux servers and all those long hours on duty helped you to gain some deep technical knowledge. Of course, we don’t expect you to master everything (this note was added by our HR so that you don’t get scared).
- You’ve mastered the configuration of LAMP, reverse proxies, MySQL servers; you know RAID, LVM, and the difference between a RAID, a backup and a snapshot
- A good theoretical and in-depth understanding of Linux regardless of its distributions and uses and experience with your own LFS, Gentoo, ArchLinux or *BSD
- You have experience with configuring a solution with a cluster or you’re at least familiar with its upsides and downsides
- You enjoy using git, config management, bash
- Despite your seniority you constantly feed your hunger for knowledge with new information and you are willing and capable to transfer the knowledge to your junior fellow colleagues
- You are equipped with decent English and are not afraid to use it.
You will take care of:
- A large web cluster that we call IT1.3
- Over 200 servers, 400 pieces of cpu, 3200 physical cores/6400 logical cores, 30+ TB of RAM, 400 TB of RAW SSD disk capacity
- A database cluster
- Mail servers and load balancers
- OpenStack architecture and virtual servers
- Internal systems and applications in Docker containers
- Private solutions tailored to our customers’ needs
- The ZFS file system that gives us excellent control over backups and disaster-recovery solutions
What you can expect from us
- Support from an experienced team: colleagues always ready to help
you with stuff you don’t feel confident about and who help you grow the
best side of you
- Trust in your abilities: your opinion will be listened to and your voice
listened to when creating and implementing complex infrastructures
- An opportunity to grow: we encourage you to attend meetups and
conferences, both as an attendee or a speaker, learn foreign languages
and deepen your knowledge thanks to internal trainings and workshops
- Space for yourself: Multisport card to cover your sports activities, 6
extra holiday days, flexible working time with a possibility of home office
- Our coolture: hackathons, grill parties, breakfast, Xmas party and other teambuilding activities with your team
