      Prometheus, Grafana, RabbitMQ, Kafka etc.);
    • interesting challenge to solve - rolling out on-premise and cloud stack update for 170 gas stations that are
      working 24/7;
    • a lot of freedom and chances to learn on many fronts (no legacy code, company uses the most advanced
      tech, expecting high loaded operations);
    • you'll be able to create universal cloud infrastructure that will be used in each EU country.

    Product description

    Point of sales system ─ hardware and software that is used by customers in outdoor self-service fuel points
    and by cashiers in stores to calculate, indicate and make customer's payments.

    Key advantages of a new POS-system that is being developed:

    1. It’s a cloud-based solution written from scratch using the latest technologies. Energy retail is a specific
      market, it’s hard to build something new and as a result products are too old.
    2. No need to support legacy systems. All competitive products need to support legacy systems and can’t
      offer the same functionality, flexibility and scalability.

    The system is currently live in production and used on real gas stations since January 2020.

    Key job responsibilities and main challenges:

    • to plan & build infrastructure based on AWS and Kubernetes in a partnership with Solution Architect;
    • to improve and automate CI/CD;
    • to ensure smooth 24/7 operations;
    • to implement system elastic scalability and reliability;
    • to collaborate with developers to reach DevOps nirvana.
