The role combines hands-on backend development with analysis, integration design, deployment automation, data-model understanding and willingness to learn the securities trading domain. This a permanent, full-time position with hybrid working according to Nordea guidelines.\nAt Nordea, technology supports secure and responsible financial services at Nordic scale. In this role, your work will contribute to simplifying the securities technology landscape and improving how services are exposed to internal consumers across trading operations.\nAbout our team\nMeet the Securities Trading Operations development team. Our role is to build and modernise services that support safekeeping, settlement, asset servicing and related trading operations processes.\nThe STO Domain API is a strategic in-house developed integration layer that exposes common business services as data products. It hides technical complexity and data location, replacing point-to-point integrations with canonical services available through API Gateway.\nThe solution is built around System APIs, connectors, internal integration services and business logic components. It is intended to support use cases such as retrieving safekeeping account details, holdings, transactions, position information and other custody-related services. The target platform includes API Gateway/Kong, Kubernetes, Kotlin, Kafka and PostgreSQL, while the broader team also works with Java, IBM MQ, CI/CD and automated testing.\nThe growing team’s strategy is to increase resilient delivery capacity, strengthen mentoring and add future-proof skills across development, analysis, integration, automation and responsible use of AI-assisted development.\nMain responsibilities in this role:\nAnalyse business requirements, data models, system flows and dependencies, and translate them into clear technical designs and implementable delivery tasks. \nDesign, develop and maintain services in and around the STO Domain API, including backend code, connectors, integration services and transforming logic. \nSet up and improve integrations with source systems using Kafka, IBM MQ, REST services and related enterprise integration patterns. \nConfigure and improve the deployment toolchain, including build pipelines, automated tests, deployment automation, monitoring and troubleshooting support. \nContribute to code reviews, documentation, quality improvements, technical standards and knowledge sharing across the team.\nWho you are\nThis is the right role for you if you are a versatile backend developer with broad technical curiosity. You are comfortable moving between development, analysis, integration, and DevOps. You do not need to start as a trading-domain expert, but you should want to understand how the business process works and how technology choices affect resilience, maintainability and risk.\nYou take ownership of problems also when the answer is not obvious. You ask structured questions, document what matters, collaborate with architects and stakeholders, and help the team build maintainable solutions rather than isolated quick fixes.\nYour background and skills include:\nStrong Java experience in large-scale enterprise systems. \nAbility to analyse requirements, data models, documentation, and cross-system dependencies. \nExperience with messaging, data transformations, and API integrations from both analysis and development standpoint. \nSolid knowledge of SQL, relational databases, datastores, messaging (Kafka, IBM MQ or similar). \nExperience with Maven, Git, CI/CD pipelines, Jenkins/Bamboo, or comparable tools. \nTesting experience with JUnit, Testcontainers, and automated regression/integration testing. \nIt would be ideal if you also:\nHave experience in banking, securities trading, custody, settlement, corporate actions or another regulated domain. \nHave practical experience with Kubernetes, OpenShift-style platforms, containerisation, cloud-ready design and publishing through Kong or similar API Gateway. \nHave acted as a technical lead, mentor, code reviewer or a design sparring partner for less experienced colleagues. \nHave practical experience with AI-assisted development tools, test automation, static code analysis and other productivity-enhancing engineering practices. \nWhat we offer\nCollaboration. Ownership. Passion. Courage. These are the values that guide us in how we work and how we make decisions - and that we imagine you share with us.\nPeople are driven by many different factors. For some, it’s to take their career to the next level. For others, it’s to break new ground within their area of expertise - in other words, with us, you will always move forward.\nA culture that fosters performance and growth in one of the largest Nordic banks, offering various opportunities to evolve, develop and learn from brilliant colleagues with diverse backgrounds in a vibrant working environment.\nHybrid working model - we believe in the value of bringing people together and at the same time we embrace the freedom of flexibility.\nDiversity and inclusion are a natural part of our daily work.
