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.
We’re hiring a Senior Software Engineer who treats software as a craft, not a checklist. You’ll join a small, high-trust team where ownership is expected, curiosity is encouraged, and outcomes matter more than activity. This is not a ticket-factory role: you’ll be expected to think critically, challenge assumptions, design robust solutions, and take responsibility for their long-term success.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
