Adversus, Aarhus. Full-time. Salary Competitive.

We are seeking a Senior Full Stack Developer with an excellent understanding of web applications, eager to be part of a young developer team working with telecom and automation on top of a rock-solid UX at Adversus A/S in Aarhus.

Are you a developer who can put together an excellent performing application platform on top of a complex system? Do you have a solid feel for UX, software design, and the technical chops to bring everything together into one neat package? This position could be yours!

Adversus' ambitions are high, our organization is flat, and we always strive to learn and have fun while doing it.

Next-gen sales acceleration platform

Since 2016, Adversus has strived to be a market leader in a competitive field that requires high availability and high uptime. Adversus has experienced exponential growth in recent years, both in demand for the product itself and within the company. Today, we have 60+ employees located at our headquarters in Aarhus.

Adversus' solution is an all-in-one sales acceleration platform that supports our customers' needs for an effective, structured, and data-driven daily routine. Delivering an efficient and stable experience with a high level of usability is key to our high user satisfaction.

When spending most of their day on our platform, our users often need deep insights into their data and are always looking for ways to optimize their setup. Our platform unites three different tools: a telecommunications system, an automation system, and a CRM system. Because of these many aspects, our application needs to be able to handle the unexpected and present a solid user experience even when nothing works.

As our new Full Stack Developer, you will be welcomed with open arms by a team of 11 developers and join them in delivering the next generation of our software.

What will you be working with?

Your primary responsibilities will be implementing new features and services that extend the capabilities of our main application, as well as improving the existing ones. This includes work on our various automation systems, on-demand large-scale task processing, and keeping our integrations up to date. You will also be expected to work with our frontend application, helping to improve technical views, and sometimes prototype new interfaces for new features.

You should be familiar with async processing flows, data-driven programming, and be able to implement them both on the backend and frontend.

You should be interested in working with new technologies, and some very old ones, and be able to start working on problems where you may not know all the details up front.

We have a somewhat complicated tech stack running behind the scenes, but most of what you need to know can be covered by the following:

  • React / Typescript / Tailwind
  • PHP / MySQL / NodeJS / Redis

And some of the extra flavor you will probably end up interacting with are these:

  • Elastic search / WebRTC / SignalR / RabbitMQ

Here is how we imagine you

While a relevant degree is valued, you mainly need the technical chops and experience to call yourself a Senior Full Stack Engineer. How you acquired that specific skill set is less important. You have experience with some of our core tech stack and are ready to take on a challenge with the other technologies. You must be effective at communicating in English.

As a person, you are disciplined, reliable, and ready to be a team player. You take responsibility and understand how your development work will contribute to our customers' business needs. You love being part of a humorous work environment, and you are curious about new technologies.

This is what Adversus can offer you.

We offer you a full-time job with an attractive and competitive salary package to match your qualifications and experience. We recently moved into a newly renovated and decorated office space located right in the heart of Aarhus, providing excellent working conditions. We are flexible about many things (work-from-home days, meeting times), but we value you coming into the office most days of the week.

You will have full health and dental insurance, pension, and an IT setup tailored to your preferences. We have a Choose Your Own Lunch catering solution, and plenty of social events to let your hair down, like Friday bars, out-of-office gatherings, and summer parties.

Salary and terms of employment are negotiated individually.
