Position: Junior DevOps / SRE
Company: Cossack Labs
Experience required: 2y
English level: intermediate

Cossack Labs is looking for a **Junior DevOps engineer** to join our **Infrastructure operations team** and work with us on building secure solutions for mission-critical applications. If you are interested in systems engineering, security, building and maintaining large-scale reliable systems - this could be an interesting offering for you.

**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.

**You will**:

— Participate in designing and improving SSDLC for our products.
— Assist our clients with integrations of our software.
— Develop and maintain internal infrastructure.
— 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).

**We would expect you to have**:

— Good knowledge of Linux systems.
— Good networking knowledge.
— Good knowledge and practical experience in scripting languages: one of Python/Ruby + Bash.
— Knowledge and practical experience in at least one of non-scripting languages: C/C++/Go/Rust.
— Understanding of software development lifecycle.
— Familiar with Docker, KVM.
— Have some experience with at least one of PostgreSQL/MySQL.
— You are interested in security and are familiar with at least the most popular technologies and approaches.

** Extra skills and experience that matter**:

— Deep Linux architecture.
— Deep virtualization skills.
— SSDLC.
— Clouds.
— Advanced networking skills.
— IaaC tools and approaches.
— Advanced knowledge of monitoring approaches and technologies.
— CI/CD, packaging.
— Practical experience with bare metal.
— RPi, other IoT life forms.

**We will be 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**:

(1) 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.

(2) Environment:
— 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.

(3) Growth:
— 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).

(4) Benefits:
— 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.
