Job description

Job ID: 5743

Welcome to Group Technology, where we pride ourselves on engineering solutions and direct Nordea’s transformation by providing a holistic technological view and structured understanding of the bank, and its surrounding environment to enable the Customer Vision and the Business Strategy.

We are looking for a Senior IT Operations Engineer with a strong DevOps profile to join our Trading Data Warehouse & BI team, with a primary focus on Snowflake data warehouse operations. This is a hands‑on engineering role for someone who wants to improve how data warehousing solutions are built, deployed, automated, monitored, and operated.

We are not looking for someone who only maintains existing processes. We are looking for a proactive engineer who sees manual work as something to challenge, simplify, and automate. We would like to work with someone who has ownership to drive, and smartly use AI tools to evolve and advance the current process.

Nordea is a place where traditions meet tomorrow. We’re not just a bank; we’re a tech employer on a mission to evolve finance securely and responsibly. Together, we impact millions of people’s daily lives by ensuring they can access our solutions anytime, anywhere, while safeguarding their personal data and wealth. Join us in making an impact on the banking industry.

About Our Team

The Trading Data Warehouse & BI team supports one of the largest trading environments in the Nordics, where trusted data, reliability, speed, and operational stability are critical.

Snowflake Operations & Administration

• Administer, monitor, and manage Snowflake environment, including designing and maintaining databases, schemas, roles, and security measures (access controls, data encryption)
• Optimize Snowflake performance and storage through query tuning, resource management, and troubleshooting performance, connectivity, and security issues

DevOps & Automation

• Automate repetitive tasks including environment setup, deployments, releases, backups, data replication, change requests, and incident handling
• Build reusable scripts, tools, and platform capabilities using Python, SQL, Ansible, and related technologies to make delivery faster, safer, and more consistent
• Improve configuration management and environment consistency, turning fragile or inefficient processes into repeatable, documented, and automated solutions

Monitoring & Operations

• Establish and optimize monitoring, alerting, and logging tools for the data warehouse to support reliable data flows across ingestion, transformation, and consumption
• Support troubleshooting and incident resolution for critical data processes

Collaboration & Continuous Improvement

• Work with Snowflake, Kafka, Kubernetes, Git, Ansible, Python, SQL and related technologies
• Collaborate with data engineering teams, tech leads, architects, and stakeholders to improve engineering practices and reduce dependency on individual knowledge
• Develop and maintain automated documentation for Snowflake environments, operational runbooks, and standard processes
• Use AI tools where relevant to accelerate automation, development, testing, troubleshooting, and documentation
• Participate in code reviews, knowledge sharing, team ceremonies, and mentor junior colleagues where relevant

Who You Are

This is the right role for you if you are a hands‑on engineer with a builder mindset. You are comfortable working across development, infrastructure, data platforms, automation, and operations. You do not wait for every detail to be specified — you investigate, propose improvements, and take ownership of making things work better. You have strong learning mindset and ability to adapt across technologies and responsibilities.

Proactive approach to change and willingness to challenge manual, fragile or inefficient ways of working will help you succeed in this role as well as mentality to automate, simplify, improve and leave systems better than you found them.

Your background and skills include

• Proven experience in Snowflake operations with strong understanding of Snowflake architecture, features, security best practices, and access control
• Proficiency in SQL and database design, with experience in performance tuning and query optimization in Snowflake
• Good Python skills (or other scripting languages like Shell) for automation, tooling, testing, and operational utilities
• Experience with Kafka, Kubernetes, Git, and Ansible (or similar technologies)
• Understanding of data pipelines, data warehousing concepts, data integration, and ETL/ELT processes
• Experience in monitoring, incident handling, and documentation creation (operational runbooks, standard processes, architecture)
• Strong problem‑solving skills, attention to detail, and excellent communication and collaboration skills
• 4+ years of experience in DevOps, platform engineering, data engineering, or similar technical roles with strong practical experience in automation, scripting, configuration management, and deployment
• Bachelor's degree in Computer Science, Engineering, or related field, or equivalent practical experience

It would be ideal if you also

• Certification in Snowflake or related technologies
• Experience with data visualization tools (e.g., Power BI) and understanding of data governance and compliance standards
• Curiosity about AI‑assisted engineering and willingness to use AI as a practical productivity tool

Why join the team now

We are modernising how data warehousing is delivered and operated. Our team is actively:

• Reducing manual work through automation
• Improving platform reliability and operational stability
• Strengthening deployment, monitoring, and configuration management practices
• Using AI as a practical accelerator for engineering, documentation, testing, and operations
• Building stronger platform and DevOps capabilities
• Raising the bar on ownership, simplicity, reliability, and engineering quality

What We Offer

Collaboration. 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.

In this role we offer

• Meaningful engineering problems in a business‑critical domain
• A chance to shape DevOps, automation, and platform engineering in a major Nordic bank
• Colleagues with diverse backgrounds across engineering, data, platform, and business domains
• A culture that supports learning, growth, and continuous improvement
• A hybrid working model with both collaboration and flexibility

People 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.

A 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.

Hybrid working model – we believe in the value of bringing people together and at the same time we embrace the freedom of flexibility.

Diversity and inclusion are a natural part of our daily work. We know that an inclusive workplace is a sustainable one. We genuinely believe that our diverse backgrounds, experiences, characteristics and traits make us stronger together. Every day we strive to find new ways to improve diversity and inclusion within our community e.g. we have signed the European Diversity Charters in the countries where we operate to show our commitment and engage with others to continue learning and improving.

Studies show that members of underrepresented communities don’t apply for jobs unless they tick all the qualification boxes. If this is part of why you hesitate to apply, we would like you to reconsider and give it a chance. Maybe your profile fits our needs much better than you think.

A security clearance will be performed for the person selected for this position.
