About the role

This role focuses on contributing to the design, development, and evolution of Sedna’s VMS (Voyage Management System). It's a mature, highly specialised platform that shipowners, operators and charterers use to run chartering, voyage operations, cargo and freight/hire invoicing.

VMS has a Java backend exposing a REST API used by our own web client (React) and directly by customers' integrations. Data lives in Oracle, including a significant amount of business logic in PL/SQL. It runs on AWS and builds through GitLab CI/CD.

Sedna VMS is in use 24/7 by shipping companies worldwide. Customers run their daily operations and invoicing on it, so correctness, performance and reliability directly affect their business.

You will play a key part in raising standards and delivering new features. You'll take real ownership of features and of how they behave in production, on a product customers run their business on, and help shape how the platform evolves. You'll work with modern AI-assisted development tools as part of everyday engineering.

How you’ll make an impact

Engineering and feature development

This role contributes to both backend and frontend development. Day-to-day responsibilities include understanding requirements, shaping technical approaches, writing code, and contributing to automated tests. Development work spans a mix of new features, improvements, and maintenance, driven by both customer and product needs.

System architecture and modernisation

The role includes participating in ongoing efforts to refine and modernise the platform. This involves contributing to technical upgrade work, improving system structure, and supporting longer-term architectural direction as the product grows. Opportunities exist to participate in design discussions and help shape solutions that improve system performance, reliability, and extensibility.

Quality, testing, and delivery practices

The team maintains a focus on software quality. We combine unit tests, API regression tests (Postman) and UI tests (Playwright) with peer code review on every merge request. Releases are built and tested through GitLab CI/CD. We're actively improving here: getting more of our test suites running automatically in CI and making them reliable. Engineers who want to drive that, will have room to do it.
