Project description

edrone is an Autonomous eCommerce Cloud, is the first eCRM designed for eCommerce. We provide advanced Marketing Automation solutions, based on our algorithms, that are easy to install (Plug'n'Play). Our goal is to help to understand customers behavior (Customer Intelligence) and engage them (Marketing Automation) with an all-in-one e-commerce marketing cloud.

We're a hard-working, fun-loving, get-things-done type of team that is building a platform that helps increase client’s online sales. We know how much grit it takes to start your own business and grow it into something that lasts. We roll our sleeves up, we act fast, and we learn together.

We're looking for people that will do the same.

What we value

  • Seeking mastery. We read books, attend conferences and meetups. We have a library of books. We study alone and in groups. Company has a budget to
  • support us. We do this because it is our passion.
  • Curiosity. If we use something we want to know how it works exactly. What are the constraints, when does it fail
  • Direct, honest and timely feedback. This is how we improve.
  • Autonomy. We support each other and we actively avoid micromanagement.
  • Being a good human. We don’t tolerate jerks, no matter how brilliant they are Interesting technical challenges
  • Scalability - we ingest “tons” of data that must be processed near-real time. Traffic patterns change constantly and we have to adapt dynamically. We rely on horizontal partitioning and auto-scaling a lot.
  • Reliability - uptime, latencies, queue processing delays - we live and breathe by these metrics. We assume machines, disks, network and software will fail. Our approach is resilience engineering and automation.

  • AWS (25+ services) Java 11, git, JIRA, Confluence, WebStorm, PhpStorm, IntelliJ, Redis, Hadoop, Spark
