Today’s advertisers are facing an increasingly difficult problem when employing modern digital advertising channels, such as display, social and paid search. While the available platforms are very capable, they have developed into highly complex tools, effectively limiting their value for non-specialist users.

At Nexta our mission is to bring simplified, automated and optimized online marketing to our enterprise and SMB clients on very large scale. While only being 5 years young, our mature platform product already serves dozens of global enterprise clients, and through those thousands of SMBs and the company has been profitable from day one.

Building on this success, the AI team is expanding and is looking for a creative and driven developer to help us build the next generation Nexta AI optimization agent and especially the cloud-based infrastructure the AI agent is deployed to. Thousands of live campaigns are currently running in the Nexta system, and deploying state-of-the-art AI solutions on this scale, requires the use of modern container- and cloud-based infrastructure solutions. These are developed internally in the AI team, where you will be working, alongside our existing senior developer resources.

From a non-technical point of view, the task of the AI agent is to continuously make adjustments to live campaigns in order to improve relevant business KPIs, typically cost per click or conversion. From a technical point of view, we frame the task as a sequential decision-making process under uncertainty, and employ techniques from reinforcement learning, control theory and machine learning to solve this non-trivial task.

Requirements for the position:

  • Hands on experience developing in .NET
  • Understanding of software development principles
  • Familiarity with microservice architecture design
  • Familiarity with docker, kubernetes, message queue infrastructure
  • Familiarity with cloud services (preferably Azure)
  • Experience in working in linux environment and servers
  • Experience with continuous development practices

The work will include:

  • Researching tools and technologies
  • Working in a team under agile development practices
  • Responding to sudden changes in requirements
  • A focus on minimizing technical debt

Position specs:

  • Level: Mid to senior.
  • Type: Permanent and full time.
  • Where : Nexta HQ, Store Kongensdage in central Copenhagen. Remote or hybrid is also an option.
  • Compensation: TBD based on experience level.
  • Diversity: Nexta is an equal opportunity employer. We encourage all qualified candidates to apply.
