Our uncrewed systems are making ocean exploration and operations safer, smarter and more sustainable, helping unlock the vast potential of our oceans while reducing environmental impact.\nThis isn't a vision for the future. It's happening right now.\n As we continue to push the boundaries of innovation and redefine what's possible in the maritime industry, we're looking for exceptional talent to join our fast-growing team.\nOcean Infinity is seeking a motivated and technically capable 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 contribute to delivering robust, production-ready data infrastructure, working across data, product, and engineering teams to apply engineering standards and provide high-quality curated datasets that power analytics, operational systems, and AI initiatives across the company.\nRequirements\nWhat you will do!\nDevelop and implement scalable data pipelines that automate manual data processes and improve reliability and efficiency across the organization.\nBuild and maintain end-to-end data transformation workflows (Bronze → Silver → Gold), focusing on implementing business logic, data validation, and reusable transformation components.\nDevelop robust Python-based data processing solutions, including scripts, services, and automation tools that support ingestion, transformation, and data delivery.\nImplement 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.\nDevelop and maintain data quality checks, validation rules, and testing frameworks to ensure accuracy, consistency, and reliability of data products.\nBuild backend data services and lightweight APIs that expose curated datasets to analytics tools, reporting systems, and downstream applications.\nCollaborate closely with data analysts, product teams, and AI engineers to translate data requirements into efficient, production-ready implementations.\nOptimize and refactor existing pipelines and processes to improve performance, reliability, and maintainability, with a strong focus on code quality and automation.\nFollow and contribute to engineering best practices, including version control standards, modular pipeline design, CI/CD for data workflows, and documentation of implemented solutions.\nParticipate in code reviews and pairing, learning from more experienced engineers and sharing implementation knowledge and reusable patterns with the team.\nWhat we look for!\nA degree in Computer Science, Mathematics, Engineering, or a related field, or equivalent practical experience.\nMinimum 2 years of experience as a Data Engineer, Backend Engineer, or Software Engineer working with data-intensive systems and data pipelines.\nSolid software engineering skills in Python, with experience writing reliable, maintainable data processing code and automation workflows.\nGood SQL skills, with an understanding of query optimization and working with analytical datasets.\nExperience building and maintaining data pipelines and transformation workflows, ideally in cloud-based environments.\nHands-on experience with at least one cloud platform (e.g., AWS, GCP, or Azure), particularly for building and running data pipelines, storage systems, and compute workloads.\nFamiliarity with data lake and lakehouse environments, including object storage systems (e.g., S3 or equivalent) and structured transformation layers (e.g., Bronze/Silver/Gold patterns).\nUnderstanding of unstructured and semi-structured data storage patterns (e.g., JSON, logs, event data, files in object storage) and how to process them efficiently.\nExperience with relational and/or NoSQL databases (e.g., Postgres, MongoDB, Redis), including schema design and indexing.\nWorking knowledge of containerization technologies such as Docker.\nGood understanding of data modelling principles and how to structure datasets for analytics and downstream consumption.\nExposure to distributed systems concepts and large-scale data processing patterns, with emphasis on practical implementation and debugging.\nStrong problem-solving skills with a focus on reliability, performance, and automation in production systems.\nAbility to collaborate effectively with analysts, product teams, and engineers, translating requirements into robust, testable implementations.\nInterest in improving and refactoring existing pipelines and workflows to increase reliability, maintainability, and automation.\nComfortable working in modern engineering practices including Git-based workflows, code reviews, CI/CD pipelines, and automated testing for data systems.\nExposure to workflow orchestration tools such as Airflow, Prefect, or similar, including scheduling, dependency management, retries, and observability.\nNice to have!\nExperience working with telemetry, sensor, location, and operational technology (OT) data workloads.\nExperience processing and managing large-scale video, image, and unstructured media datasets, including streaming ingestion and analytics workflows.\nUnderstanding of feature engineering patterns and data preparation workflows supporting machine learning systems.\nExperience working with maritime, fleet, vessel operations, logistics, or industrial operational domains, including telematics, tracking, asset monitoring, or operational analytics use cases.\nBenefits\n *Salary: London £65,000 / Porto up to 55,000 EUR Per
