We are using and creating technology to transform operations at sea to enable people and the planet to thrive. We are open-minded and fearless in our approach to innovation and don't believe in boundaries. We challenge everything and have massive ambitions to drag aging industries into the tech era. We take safety, equality and education very seriously, and our responsibilities don't stop at our front door. Our business is built on the belief that there's definitely a more environmentally responsible way to operate at sea.
We employ people who share our core values. We expect our people to be courageous, trustworthy, and conscientious, driven by a desire to do the right thing. We strive for excellence, work collaboratively, and are genuinely excited by our work. We offer opportunities for our people to develop beyond their role and span a multitude of disciplines. These are open to all, regardless of background and experience level.
Working with us means being part of a team that is harnessing technology and creativity to disrupt a traditional industry. We are not your average workplace.
About the Role
Ocean Infinity is seeking an experienced and technically accomplished Senior Data Engineer to join our team. The successful candidate will focus on building and implementing scalable data pipelines and automation solutions that transform complex manual workflows into reliable, production-grade data systems. You will play a key role in delivering robust, production-ready data infrastructure, working across data, product, and engineering teams to establish engineering standards and provide high-quality curated datasets that power analytics, operational systems, and AI initiatives across the company.
What will you do:
- Develop and implement scalable data pipelines that automate manual data processes and improve reliability and efficiency across the organization.
- Build and maintain end-to-end data transformation workflows (Bronze → Silver → Gold), focusing on implementing business logic, data validation, and reusable transformation components.
- Design and develop robust Python-based data processing solutions, including scripts, services, and automation tools that support ingestion, transformation, and data delivery.
- Implement data integration pipelines across a variety of sources, including operational databases, external APIs, and event/streaming data, using both batch and near-real-time approaches.
- Develop and maintain data quality checks, validation rules, and testing frameworks to ensure accuracy, consistency, and reliability of data products.
- Build backend data services and lightweight APIs that expose curated datasets to analytics tools, reporting systems, and downstream applications.
- Collaborate closely with data analysts, product teams, and AI engineers to translate data requirements into efficient, production-ready implementations.
- Optimize and refactor existing pipelines and processes to improve performance, reliability, and maintainability, with a strong focus on code quality and automation.
- Follow and contribute to engineering best practices, including version control standards, modular pipeline design, CI/CD for data workflows, and documentation of implemented solutions.
- Support and mentor other engineers through code reviews, pairing, and sharing practical implementation knowledge and reusable patterns.
