About the Role

As a Senior Software Engineer, you will primarily work with Nordiska Embedded. We combine the best of two worlds - at our core, we’re a stable, regulated bank paired with a product-tech mentality that thrives on agility, curiosity, and innovation. As Nordiska expands into new markets, onboards new customers, and builds new products and features, you work closely with the Tech Lead and Lead Engineer to set technical standards and ensure that the team’s output is robust, scalable, and secure.

In addition to your technical work, you’ll mentor engineering colleagues, foster a culture of continuous improvement, and contribute to a high-performing team as we grow.

What You’ll Do

• Drive engineering excellence by defining technical standards, system architecture, design principles, and contributing to the long-term technology strategy.
• Deliver high-impact features – implementing complex functionality that meets stringent performance, reliability, and security requirements.
• Drive initiatives that improve performance, enhance scalability, and reduce technical debt.
• Anticipate and resolve architectural bottlenecks, proactively preventing issues.
• Ensure technical excellence through clean code, testing and observability, structured code reviews, and consistent application of best practices, fostering a culture of continuous learning.
• Cross-functional collaboration with Product and Engineering leadership to ensure technical execution supports strategic objectives.

We’re Looking for Someone who has

• Senior-level depth in programming, frameworks, and system design in C#/.NET.
• Expertise in event-driven architecture (EDA) and Azure; a strong interest in AI technologies is considered an advantage.
• Hands-on expertise with architectural patterns, scaling strategies, performance optimization, security, scalability and resilience.
• Demonstrated capability to mentor others and lead by example.
• Proven track record of delivering high-quality, large-scale software systems.
• Fluency in Swedish and English, both spoken and written.

Your Professional Profile

• As a true self-leader, you take ownership and operate effectively in a fast-paced, high-accountability environment.
• You communicate clearly, collaborate seamlessly across functions, and navigate confidently in a regulated context.
• You’ll contribute to a high-performing and humble team, bringing strong analytical skills and a proactive, solution-driven approach.
