Due to further expansion, we are seeking a Senior Software Engineer to help us to continue to dominate one of the most buoyant, fastest-growing industries, that is changing the world and the speed at which we receive items.

What we do

LineTen is on a mission to crack the code on urban delivery. By leading with our values and putting carrier partners first, we are paving the way for better delivery experiences. LineTen is a new approach to delivery with a free carrier API and an operations management platform for shippers. We're building the first global data-driven last-mile network that has the potential to solve industry-wide problems.

Why work with us?

• We Are a Home-First Team: LineTen is committed to our home-first policy, which means that we honour remote working first, and offer office space in London, England and Porto, Portugal.
• We Believe in Having Fun: Our WellUs team organises monthly events like Pet Zoom Calls, 45-minute Yoga classes, and after-hours cocktail lessons.
• We Want You to Take a Break: We believe it is the quality of work that matters, not the hours spent “on the clock”. We offer flexible working hours and unlimited vacation.
• We Work in Teams: We work in teams rather than as individuals. Some teams, like our Product Teams, have agile ceremonies such as standups and sprint planning.
• We Pitch Our Ideas: We independently sketch ideas then come to team discussions with prototypes instead of trying to reach consensus through extended discussion.
• We Challenge Norms: We don’t want to be typical. We believe in challenging the status quo. We encourage our teammates to make their jobs their own.
