Senior C++ Software Engineer in London

What makes us Qlik? A Gartner Magic Quadrant Leader for 15 years in a row, Qlik transforms complex data landscapes into actionable insights, driving strategic business outcomes. Serving over 40,000 global customers, our portfolio leverages pervasive data quality and advanced AI/ML capabilities that lead to better decisions, faster.

We excel in integration and governance solutions that work with diverse data sources, and our real-time analytics uncover hidden patterns, empowering teams to address complex challenges and seize new opportunities.

We are looking for a Senior C++ Software Engineer to join the R&D team responsible for the "brain" of Qlik: our high-performance calculation engine. As we push the boundaries of data analytics with massive scale and real-time processing, we need a software engineer who can tackle complex architectural challenges and ensure our core remains the fastest and most efficient in the industry.

You will solve problems related to resource optimization, concurrency, and high-volume data processing, directly impacting how thousands of global customers derive value from their data.

What makes this role interesting?

• Touch the Core of Innovation: You aren’t just building a feature; you are working on the Engine - the sophisticated high-performing backend component that has powered Qlik for 30 years and is now evolving with next-generation technologies like AI and cloud-native scaling.
• Deep Technical Mastery: This role offers the rare opportunity to work on high-performance computing problems. If you enjoy low-level optimization, complex algorithms, and seeing your code handle vast quantities of data with maximum efficiency, this is the place to be.
• Global Impact: You’ll be part of a small, highly collaborative Scrum team where your voice is heard, yet your work will be deployed instantaneously via our continuous delivery pipelines to our global cloud and on-premise customer base.
• The Challenge: The primary challenge is balancing the "Quality First" requirement of a mature, mission-critical engine with the need for high-speed innovation. You will be tasked with modernizing core components while maintaining the extreme reliability our customers depend on.

Here’s how you’ll be making an impact:

• Architecting the Future of Analytics: You will design, develop, and maintain the functionality within the Analytic Engine, translating complex product requirements into elegant, high-performance code.
• Driving Engineering Excellence: By performing deep code reviews and mentoring team members, you will help maintain our high standards for integrity and software craftsmanship.
• Ensuring Seamless Reliability: You’ll take ownership of the full development cycle, including automated testing, to ensure that every fix or feature addition strengthens the engine’s core.
• Collaborative Problem Solving: Working alongside senior architects and product management, you’ll help identify the right designs for implementations that scale.
• Direct Customer Value: Your work directly enables our customers to process more data, faster. When you optimize a calculation or solve a scalability bottleneck, the impact is felt immediately across the entire Qlik ecosystem.

We’re looking for a teammate with:

• 10+ years of software development experience, with a minimum of 7 years dedicated to C++.
• A Bachelor’s degree in Computer Science or a related field, or similar.
• Familiarity with Linux development environments and modern toolsets like Git, GitHub, Jenkins, and Jira.
• Experience in high-performance computing or microservices, with an understanding of API development and test-driven development.
• Strong communication and interpersonal skills, with a proven ability to drive cross-team activities (design, testing, and documentation).
• A "Quality First" mindset and a passion for working in a multicultural, Agile team environment.

The location for this role is: Lund, Sweden (Hybrid)

Apply now and help change how the world transforms complex data landscapes into actionable insights and turns complex data challenges into new opportunities.

What else do we offer?

• Genuine career progression pathways and mentoring programs.
• Culture of innovation, technology, collaboration, and openness.
• Flexible, diverse, and international work environment.
• Giving back is a huge part of our culture. Alongside an extra "change the world" day plus another for personal development, we also highly encourage participation in our Corporate Responsibility Employee Programs.
