Middle Linux engineer / administrator
Kyiv・Full time・More office than remote // A mix of system engineering, security and operations.
The opportunity #
Cossack Labs is looking for an experienced Linux systems engineer / system administrator to join the operations team and work with us on making innovative security tools robust, reliable and efficient. If you are interested in systems engineering, security, building and maintaining large-scale reliable systems - this could be an interesting offering for you.
We are a data security solutions company, developing software products (open-source and proprietary), as well as providing custom bespoke solutions to innovative development teams around the world. Our mission is to make strong security methodologies and approaches convenient within modern infrastructures and, as the software is eating the world, help it eat the world responsibly, without leaking customer’s data.
Among our customers are power grid operators, payment processors, legal companies, million-user customer applications. We cater to young ambitious startups and well-established enterprises, who use our software and solutions as core part of their security arsenal.
Our mission would be impossible without brilliant engineering force, and we’re looking to grow it.
You will: #
- Participate in planning, building and maintaining infrastructure: internal, developer, customer, R&D.
- Participate in working out internal procedures, standards and flows.
- Have an individual set of “growth work tasks” depending on preferred further direction of growth (there are a lot of options).
Technical stack: #
- OS: Linux Debian (mostly), RHEL, Alpine, other Linux distributions just for niche solutions, no MS products at all.
- VPN: IPSec, OpenVPN.
- Virtualization: KVM, Docker.
- IaaC: Ansible, Chef, Terraform.
- DB: PostgreSQL (mostly), MariaDB/MySQL.
We expect you to have: #
- Deep knowledge of Linux systems.
- Strong networking knowledge.
- Practical experience with bare metal.
- Good virtualization knowledge: KVM, Docker.
- Troubleshooting skills.
- Good script languages skills: Python/Ruby, Bash.
- Understanding modern software development principles.
- Some experience with Infrastructure as a Code (at least one of Ansible/Chef/Puppet/Salt).
- Practical experience with RDBMS (at least one of PostgreSQL, MySQL).
Please note that you can be a perfect fit even if not everything we’ve outlined above applies to you. If you have any questions, please don’t hesitate to ask – everyone is unique.
Extra skills and experience that matter: #
- Extended programming skills.
- RPi, other IoT life forms.
- Networking hardware: modems, switches.
- Security (OS-level, app-level or infra-level).
- Advanced knowledge of monitoring approaches and technologies.
We will feel comfortable working together if you: #
- Don’t get desperate to find and read documentation. Of course, each of us is always ready to assist with approaches and search for solutions, but we respect the time of colleagues, and we can read reference information on our own.
- DO NOT think that good advertising replaces deep knowledge.
- You don’t necessarily like to write, but you do write good technical documentation.
- You’d rather do well once than constantly generate monkey patches.
- You’re not deprived of healthy perfectionism, a sense of beauty and a sense of humour.
We offer: #
- Friendly and experienced team: smart people to learn from, great people to build with. Each of us is unique, we value and support each other.
- An atmosphere that motivates you to grow and get smarter every month, a healthy ratio of routine / experimentation.
- Trust: schedule, reporting, bureaucracy is kept at reasonable minimum. We hire smart people and trust them to do the right thing. When things go wrong, we help rather than punish.
- Shared decision making: this business is driven by engineering excellence, so engineers are important part of tactical and strategical business decisions.
- Friendly to humans: not just a formal vacation and sick leave quota. Feel like your mental or physical wellbeing needs care? Take some time off. Feel like working a few days from home? Sure. As long as you’re in line, we are here to support you when you’re not.
- On this position, you can grow into full-on Site Reliability Engineer, security architect, security engineer with infra bias, - depending on type of tasks and challenges you find exciting.
- Team that facilitates internal learning and growth all the time.
- Interesting technologies to work with — sometimes, even unique ones (we design applied cryptography schemes and techniques and novel ways to use them).
- Ability to grow into one of the fastest growing industry sectors (computer security) with a team of experienced professionals.
- Management attention to help you improve upon your personal goals (through regular 1:1s and mentoring).
Unique experience #
- Interesting challenges, great variety—one day you might be setting up deployment environment for IoT devices that run our code on power plants, the other day — manage intricacies of cross-datacenter database replication.
- Reasonable time budgets and attitude to build things well – we build for decades, rather than till next release.
- Work at the intersection of technologies: software development, information security, cloud/on-prem infrastructure engineering. You won’t be bored :)
- A sense of meaning and responsibility for those who seek purpose – we’re building “invisible texture of modern civilization”—bits of infrastructure finance, power grids, healthcare rely on, and we are trusted with very challenging aspects of it.
- Competitive compensation with flexible bonus scheme.
- Sick leaves, 21 vacation days a year, extra days off — according to agreements and laws.
- Conferences, books, courses — we encourage learning and sharing with the community. Our team members share a lot in talks, workshops and blog posts.
Not sure but considering? Talk to us. #
If you see yourself fit but a few things are off — don’t hesitate to talk anyway. It might be that your unique combination of skills and knowledge would be perfectly fitting for our environment, but we both just don’t know it yet.
How to apply?
We'd like to get your CV to start a conversation. A supporting letter explaining your story, your interest in security and operations, what you have done in the past and what kind of work you find interesting would help, but is not necessary.
