Job Description

Who we are


Paack is one of the hottest technology start-ups in the logistics sector. It was founded in 2015 by three Spanish friends and, since then, the company is experienced a strong global growth and presently operates in 70 cities across four countries. All of our success is backed by a number of renowned European investors. And this is just the start.


We believe that the future of eCommerce deliveries is customer controlled time-slots, combined with a nature-positive approach to sustainability. We are on a mission to make this the new standard.


Our truly customer-centric and sustainable delivery services ensure customers receive parcels at their convenience, at a time that suits them. Our proprietary technology combined with our operational excellence enables us to deliver parcels more successfully and efficiently than ever before.


This creates unprecedented results for our retail clients through customer experience, eCommerce sales increases, loyalty and retention, thus empowering them with powerful competitive advantages whilst at the same time reducing the impact of deliveries on the environment. The best retailers in the world, such as Amazon, Inditex Group (Zara), H&M, El Corte Ingles and many more choose Paack as their exclusive partner for deliveries due to these reasons.


Our team is multicultural, multilingual, highly qualified, entrepreneurial and, inherently, we like to work hard. We enjoy all the challenges of scaling a global technology and logistics business, and we face them with ambition. At Paack we look for passionate and committed people who own their individual projects and see them through, inspire and support others as part of a team, whilst constantly looking to improve through their own ideas and initiative to help the business achieve its key objectives.

Team members are free to move between different teams based on the feedback of their team members and status of their project.


How will my day be?


Our team is very diverse and we work from different locations across the globe in different time zones. We follow agile practices like sprint planning, daily standup and retrospectives through slack.We perform pair programming sessions and weekly developer talks.


Why should you work with us?
