Opportunities for you:

Professional growth: quarterly Growth Cycles instead of performance review;
Experience: knowledge sharing through biweekly Tech Talks sessions. You will learn how to build projects that handle petabytes of data and have small latency and high fault tolerance;
Hybrid work approach: you can choose where you work better remotely or in the office.

Who are you?

You have a strong understanding of large-scale computing solutions and think of infrastructure as code. You love the idea of building immutable infrastructure and multi-AZ/multi-region fault-tolerant systems that are anti-fragile. While you understand the need for monitoring and alerting, you dream of building self-healing systems. You believe in collaboration, acting as a force multiplier, and making the right tradeoffs.

What would make you a strong fit:

5+ years of experience as a software engineer of infrastructure/platform services or SRE;
Strong programming skills with such languages as Java or Scala, or Python;
Extensive experience building & managing cloud infrastructure on AWS or GCP;
Experience building infrastructure as code and automating infrastructure provisioning steps, such as CloudFormation/Terraform;
Strong experience with monitoring and alerting systems, both open source and commercial;
Familiarity with Docker and container clustering technologies like Kubernetes, GKE, or AWS ECS;
Experience solving problems with production systems, and building solutions and automation to prevent them from reoccurring;
Proven experience with automation and knowledge of configuration management tools.

What you’ll do:

Build immutable infrastructure and multi-AZ/multi-region fault-tolerant systems that are anti-fragile;
Multi region deployment: deploying Bigtable cluster which spans multiple regions (how can we make a specific customer stick to a specific region, sticky sessions at region level);
Local development and testing as fast and painless as possible;
Create Dynamic environments (complete env to a specific service talking to other env.);
Bot - deployment to monitoring via slack.

Benefits and Perks:

A compensation package that consists of financial compensation, a biannual 5% bonus, and stock options;
Medical, dental, and vision coverage;
50$ for sports and wellness;
Education reimbursement: books, education courses, conferences;
Flexible time off: we follow an unlimited vacation approach;
Tuned work schedule to Kyiv timezone despite US offices location: biweekly demo sessions are optional for our team and we watch them from recording;
Mental Health Days: additional day-offs;
English courses and social activities inside the company that allow improving your public speaking and language.

Our interview:

We follow the same process for all teams, technical interview consists of 2 parts:

60 min technical pre-screen interview;
Virtual on-site interview: 4 sessions, 45 mins each, that cover coding, system design, experience, and soft skills.

During our sessions, you will have the opportunity to learn about company culture, meet engineers from your team and discuss distributed system problems. You will have time for all interesting questions and get transparency regarding your future responsibilities and the project.
