DeepSea is a maritime technology leader, providing a unified optimisation platform that helps shipping companies cut fuel consumption, reduce emissions, and transform vessel performance across entire fleets.

Built on the most advanced maritime AI data pool in the world, DeepSea’s platform powers everything from vessel monitoring to advanced automation - helping clients achieve measurable results with clarity, speed and scale.

We are trusted by some of the world’s most forward-thinking ship owners and operators, and our team spans Greece, the UK, Armenia, Romania, Singapore and Japan. As the shipping industry undergoes enormous change, we are at the centre of that transition - helping our customers take control, reduce risk, and build competitive advantage.

Main Responsibilities

• As a member of the company's Voyage Optimization department, you will collaborate with Back End, Optimization, Quality Assurance and  Front End  Engineers  within the department.

• Work on the development Route&Speed Optimization solutions, from understanding and improving existing algorithms, to finding and resolving the overall system’s bottlenecks, to development and deployment of new optimization algorithms.

• Communicate and collaborate with internal stakeholders (product owners, naval experts, customer success managers, MLOps engineers) to understand business needs and requirements and present complex concepts to non-technical audiences, including external stakeholders and customers.

• Investigate completed voyages which raised customer’s concerns, justify and explain the behavior of our optimization pipeline, identify areas of improvement and plan the resolution.

• Another important responsibility is algorithm evaluation, such as developing internal tools for savings analysis or studying vessel data (sensors, weather) and delivering brief research reports (occasionally, upon customer or stakeholder request).
