Your Role

We are looking for a Senior Backend Engineer who enjoys taking ownership, thinking beyond individual tickets and actively shaping a growing platform.

In our environment, backend engineering means more than implementation. You will be involved in technical decision-making, architectural evolution and improving how we build and run our systems. As we grow, this role can naturally evolve towards technical leadership or a lead position, depending on your interests and strengths.

What You’ll Do

• Drive the further development of our backend systems and services
  

• Take part in architectural decisions and backlog prioritization
  

• Refactor and improve existing codebases, reducing technical debt
  

• Build and enhance APIs to make our platform more accessible and scalable
  

• Automate internal processes to support business teams and customers
  

• Take shared ownership of DevOps topics, including deployment, monitoring and reliability
  

• Orchestrate Docker containers for stable deployments on AWS
  

• Build and maintain automated deployment pipelines (e.g. Drone.io, Cypress)
  

• Create and maintain clean, sustainable documentation
  

What You Bring

• Strong experience with backend development in a production environment
  

• In-depth understanding of Django and Django REST framework or similar
  

• Python proficiency (must-have)
  

• Hands-on experience with DevOps practices, including CI/CD, containerization and cloud environments
  

• Experience with Docker and AWS; OpenSearch and monitoring tools are a plus
  

• A pragmatic, quality-driven engineering mindset with a sense of ownership
  

• Ability to balance code quality, delivery speed and system reliability
  

• Enjoyment of working in a collaborative team that shares responsibility and impact
  

• Bonus skill: a surprisingly solid taste in bad music for the perfect sprint song
