Senior Software Engineer – Architect Scalable Secure Systems

UrbanUrban; Stockholms kommun; On-site; Full time

Job description

About the Role

As a 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, 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. You’ll be an important part of modernizing systems, reducing technical debt, and are a key contributor to system architecture, complex feature development, and code quality.

In the role, you will:

• Drive engineering excellence by defining technical standards, system architecture, design principles, and long‑term technology strategy for engineering excellence.
• 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 best practices, clean code, testing/observability, and a culture of continuous learning.
• Ensure technical excellence through structured code reviews, consistent application of coding standards, and alignment with established best practices.
• Collaborate cross‑functionally and work closely with Product and Engineering leadership to ensure technical execution supports strategic objectives.

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.

We believe that you have:

• Mid‑or senior‑level depth in programming, frameworks, and system design in C#/.NET.
• Expertise in event‑driven architecture (EDA) and Azure, with a strong interest in AI technologies 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.

Please note that we are also recruiting Software Engineers within our Scala stack.
