Wat ga je doen?

PostNL is becoming a postal tech company. To code our future, increase our agility and keep ahead on a growing and changing demand in E-commerce, we are looking for a Senior Cloud Platform Engineer within our API C4E (Center for Enablement). As a Senior API Engineer you will guide adoption and change within the organization through your technical cloud knowledge combined with your excellent communication and connecting skills. Because PostNL is currently implementing a modernization/rationalization of its application portfolio based on MACH (microservices, API-first, cloud native & headless) principles, “API first” is one of the guiding principles in this company-wide program. 


The I-API C4E is a cross functional team, responsible for the API portfolio of PostNL in terms of strategy, governance and best practices. As a Senior API engineer you contribute to the mission of the I-API C4E by knowing every pillar in our API platform and by consulting the teams how to use it in the most efficient and effective way.  

The I-API C4E provides the development teams with reference integration patterns based on best practices. You possess the skills to create these integration patterns and document these allowing others to adopt them or iterate on them. It is also your job to recognize impediments which teams experience when adopting E2E API connectivity. You analyze these and you propose solutions to these problems. Within the I-API C4E we work according to Agile methodologies. With your team you define and prioritize features and refine and build user stories so that they can be reliably executed during a sprint.   

Onze ambitie

The core mission of the I-API C4E is to free the development teams within PostNL from concerns around generic API conditioning, deployment, governance, and enable them to focus on maximizing feature delivery. You are the one who guides the adoption and the change within the organization.   

We would love to hear from you if the following characteristics resonate: 

  • A Bachelor or Masters Degree in Computer Science or a related field; 
  • Extensive experience as a DevOps or Platform Engineer; 
  • A good working knowledge of networking, network security and network services; 
  • Experience with analysing business processes and developing integration patterns using an API framework.  
  • A deep understanding of integration patterns, application stacks, Cloud operating models and the trade-offs involved.  
  • Love working with application developers and are also able to write code yourself (e.g CDK, ADF Cloudformation, Python, Typescript) 
  • Self-starting and self-organizing and a diverse & all-inclusive engineering culture; 
  • Fluent in DevOps and AWS CI/CD tools; 
  • Curious to learn the Dutch language and to understand our Logistic jargon. 

You have the eagerness to share knowledge and explain technical solutions to a broad IT audience and you feel comfortable working in a rapidly changing and competitive environment.  

Wat bezorgen we jou?

  • Competitive salary based on experience and the talent you bring to the table. Salary € 4.264 till maximum € 6.201 based on fulltime and in accordance with the PostNL Collective Labor Agreement;  
  • Part- or fulltime position 32 till 37 hours with view to permanent contract;  
  • Great benefits including 25 vacation days and 8% holiday pay and attractive Pension benefits;  
  • A dynamic, flexible and entrepreneurial environment with an innovative and collaborative PostNL team, and external suppliers creating value to the platform;   
  • Professional growth opportunities, for example as technical lead or skills diversification to other languages, platforms or in-depth development and specialism;   
  • Room for personal development through education and training in the PostNL learning environment, content driven and knowledge sharing sessions;  
  • Laptop, mobile phone and compensation towards your travel costs.  


As a Senior API engineer you will work together with professionals in the field. Within the I-API C4E team you work together with 4 team members. You are part of this transformation, where you make the difference. 



We look forward to receiving your application by means of CV and motivation.   


PostNL aims to be the favorite logistics company for everyone. Therefore everyone is welcome to join us irrespective of where you were born, what your beliefs are and who you love. We are just looking for great talent.
