About Sedna Sedna is at the forefront of revolutionising global trade, serving as the North Star for businesses navigating the complexities of international commerce.

You can find out more about us on our website: https://sedna.com/ About the role This is where you come in. As an Application Support Engineer (L2), you'll be part of a support team spanning Cape Town, Athens, and colleagues across Norway and South America, giving us close to round-the-clock coverage and a genuinely global view of our customers.

Take part in the team's on-call rota alongside colleagues across our global support locations, helping deliver the round-the-clock coverage our customers expect (locations and timings to be confirmed). Engineering and Product collaboration Team up with Engineering and Product to resolve client-reported bugs and broken features, arming them with the context they need to move fast.

Keep communication sharp and real-time across internal channels, meetings, email, bug reports, and documentation, so nothing gets lost in translation on its way to a fix.
