Full Stack Engineer

Department: Technology & Engineering

Location: Berlin, Berlin

Employment Type: FullTime

We are a growing SaaS start-up with an international team, operating on the intersection between two of the world's most fascinating industries - global shipping and global travel.

Over 90% of global trade depends on ships, and the shipping industry depends on the 2 million seafarers who operate them. What most people don't know is there's a complex, mission-critical travel operation going on 24/7 to bring seafarers to the ships where they're needed, when they're needed. That's called crew logistics, and without it, global trade wouldn't function.

But it's an operation often built on manual processes and legacy systems, meaning high-stress for operators, an unreliable experience for seafarers, and poor outcomes for the industry. That is until Tilla enters the scene.

Backed by strong investor support, with more than 10,000 crew changes executed in the platform each year across over 600 vessels globally, our platform is a game changer in crew logistics, streamlining collaboration between operators and seafarers, making crew operations more humane, efficient, and cost-effective.

Join us on the next chapter of our growth journey and tackle this overlooked yet critical global challenge: every crew change, optimized and digital.
