Full Stack Engineer

We are looking for a full stack engineer to join our engineering team. As a full stack engineer you are part of the team responsible for developing our Django Rest Framework based API and the Ember.js based SPA that serve our customers on api.loadimpact.com and app.loadimpact.com respectively.

A number of soon to be started projects makes this an extra good opportunity to join a growing technology company where you, as a developer, is part of our product’s primary target audience.

We value detail-oriented team players with good communication skills. We work in small, focused teams of 2-3 engineers where collaboration, feedback and trust are important aspects. We try to minimize meetings, move fast and work asynchronously using Trello, Github, CircleCI and Slack. This allows engineers flexibility in terms of choosing location to work from. We value the ability to work remotely.

We believe engineers should take ownership of their code from planning to release making sure it stays performant and reliable. We are in the process of fully containerizing our environments and deploy apps to our container clusters using Ansible. We encourage open source involvement and take time to contribute changes back upstream when we make improvements to our dependencies.

This position is primarily for our office located in Stockholm, Sweden, but we will also accept remote candidates if you are exceptional and have previous experience working remotely. Our office is very centrally located near Slussen, by the way, with a fantastic view of the city harbour :)

At Load Impact English is the default language, we are made up of people from Bulgaria, Macedonia, Russia, Spain, Sweden and the US.

  • About Load Impact

    Load Impact is the world’s most widely used online load testing service, with over 200,000 users from 190+ countries and over two million executed load tests - Google “web load test"!

    We are a small company but very experienced in developing applications for performance testing and monitoring. Starting way back in 2000, we have been developing performance test and measurement software for customers such as Nasdaq and the European space agency. We have written both hardcore, low-level networking software and high-level web user interfaces and become quite good at both of those things. We pride ourselves on understanding the lower levels of a networked application while at the same time realizing how incredibly important UX is. In 2009 we took the step and launched loadimpact.com. In 2011 it was made into a pure cloud service, and we have never looked back.

    We are located in Stockholm, Sweden, New York City and San Francisco, USA.
