Quick Summary

Seeking a Systems Developer in Aarhus, Denmark, to initially focus on developing, improving, and ensuring the stability of a complex internal platform used for billing and data processing, utilizing PHP, MySQL, and Redis, along with integrations to Salesforce and e-conomic. The role will transition to implementing new features, automation systems, and large-scale task processing within the core sales acceleration application. Candidates must be effective communicators in English, experienced with async processing and data-driven programming, and expected to work primarily from the Aarhus office.

Adversus, Aarhus. Full-time. Salary Competitive.

We are seeking a Systems Developer eager to help develop, improve, and maintain a complex system for billing, data processing, and general internal operations. You will join 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 a robust and reliable service platform on top of a complex system? Do you have a solid feel for business operations, 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.

About Adversus

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 mainly located at our headquarters in Aarhus.

Adversus' solution is an all-in-one sales acceleration platform with our core product being an outbound dialer for sales teams. Our application supports our customers' needs for an effective, structured, and data-driven daily routine. Usability regarding UX and UI is key to our high user satisfaction.

As our new Systems 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?

In addition to the core Adversus application, we have developed a considerably complex system for internal business processes, billing, and CRM activities. Your main responsibility will initially be to continue development, mitigate issues, and ensure the stability of this internal platform.

Over time, we see your focus shift to our core application, although you will remain responsible for development efforts on the internal platform as needed. For our core application, your primary responsibilities will be implementing new features and services 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 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. Async processing flows and data-driven programming regarding both backend and frontend shouldn’t be completely unfamiliar territory.

We have a somewhat complicated tech stack running behind the scenes, but you will initially work primarily with the following technologies:

  • PHP / MySQL / Redis
  • Integrations to Salesforce and e-conomic

Later on, it will be possible to work with other technologies in our stack, e.g.:

  • React / TypeScript / Tailwind
  • NodeJS / Elastic search / WebRTC / SignalR / RabbitMQ

Here’s how we imagine you

While a relevant degree is valued, you mainly need the technical chops and experience to call yourself a Systems Developer. 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 contributes 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 like Friday bars, out-of-office gatherings, and summer parties.

Salary and terms of employment are negotiated individually.
