Senior Python Developer

Full-time · Utrecht, The Netherlands

We are committed to delivering sustainable and high-quality software. This includes working with MyPy and flake8 and writing extensive unit and integration tests. We also have a strong focus on code reusability, both within projects and across projects. The products we deliver are built using cloud-native technology. We use a mix of serverless and container orchestration platforms to run our Python-based projects.

The projects range from integrations with SaaS services (commercetools, Contentstack or Contentful), external systems such as payment providers, ERP, CRM systems to comprehensive Django and/or Wagtail-based content websites or customised applications with (ReST) APIs to access data in a consistent way.

About us

We have a passion for technology. We get excited about solving new challenges through an elegant approach with tech solutions that best fits the demand. We do this in multidisciplinary teams working for long-term, mostly international customers. We create digital products for our clients. These are global e-commerce platforms, content websites or high-traffic middleware solutions. All based on cloud native technology, often in combination with headless SaaS products.

The work takes place in sprints of 2 to 3 weeks, where the teams from Lab Digital consist of, for example, a number of developers, (UX) designers, QA specialists, business analyst, solution architect, scrum master and project manager. Within this team, you can then take responsibility for delivering high-quality software together with the team and the client.


As a Senior Python engineer, you are working with your team to realise technical solutions that fit the demand. You are able to independently bring substantial features from concept to production. This includes being responsible for:

  • Realising robust and scalable technical integrations with external systems (e.g. headless CMS, ERP systems, e-commerce platforms, payment providers, etc).
  • Translating requirements into a technical architecture, solution and final implementation.
  • Creating well-documented, high-performance ReST APIs.
  • Support teammates in their work and provide and process feedback in a well-structured manner.
  • Help define, implement and improve our internal standards regarding code style, maintainability, scalability and reusability.


  • 5+ years of experience developing (web) applications.
  • 3+ years' experience developing within Python frameworks such as Django or Flask.
  • Good knowledge of modern software development techniques (unit/integration testing, ci/cd pipelines, etc).
  • Experience running Python applications on containerised (Docker/Kubernetes) and/or serverless (Lambda) functions.
  • Strong verbal and written communication skills in both Dutch and English, and thus able to deliver technical documentation.
  • Experience with writing applications in the e-commerce domain such as payment solutions, links to ERP, CRM and order systems, etc.

Nice to have

  • Experience with event-driven software architecture and messaging queues such as SQS, Kafka, RabbitMQ
  • Knowledge of AWS/Azure and infrastructure as code principles (Terraform)
  • Experience with the open-source Wagtail CMS
