A person in this role should have full competence to perform tasks of medium and high level of complexity.

This is an opening in multiple teams, giving you a chance to choose between working on one of our flagship products or some of our grassroot projects. Either way, you’ll be facing interesting architectural challenges involved with building a scalable, global, and resilient system capable of handling hundreds of millions of devices.

  • Experience with full software-development lifecycle.

  • Readiness to work on full-stack (frontend + backend) issues.
  • Strong problem-solving skills and a willingness to take ownership of technical challenges.
  • Passion for technology, sense of responsibility for your work and willingness to expand and share knowledge.

A huge plus if you have experience with:

  • Attend and actively participate in team meetings. Collaborate with product management, design, and site reliability teams.
  • Conduct technical interviews for junior software engineering candidates.
  • Provide developer support during office hours and occasional, additionally paid standby during production upgrades and other maintenance procedures.

What we offer

  • Freedom and responsibility. Our goal is to inspire people more than manage them. We want our teams to do what is best for our products. This, in turn, generates a sense of responsibility which drives us to do great work.
  • Dream Team: A dream team is one in which all of your colleagues are extraordinary at what they do and highly effective working together. We model ourselves on a professional sports team, not a family. A family is about unconditional love. A dream team is about pushing yourself to be the best possible teammate. Dream teams are about performance, not seniority or tenure.
  • Technical challenges: our customers depend on the reliability of our products to generate revenue in their business. The telco industry is ever-growing and needs us to support that growth.
  • Open-source contribution opportunities.
  • A team of highly skilled and humorous colleagues.
  • Access to the best tools and equipment available in the market.

  • Multisport card.
  • Medical care.
  • Kitchen full of snacks and treats (including Good Lood ice cream).
