The Role

As a Senior Specialist - Software Development reporting to the Head of Market Data and AI Enablement, you'll play a key role in designing, building, modernizing, and supporting business-critical enterprise applications. You will be part of the team responsible for Nasdaq's Market Data Platform, powering market data experiences across Nasdaq.com and supporting millions of retail investors worldwide. The platform processes and serves market data at massive scale, handling approximately 300 billion requests per month, making it one of Nasdaq's most visible and business-critical technology platforms.

Working closely with global teams and stakeholders, you'll leverage your expertise in C#, .NET, API development, SQL Server, and modern engineering practices to deliver secure, scalable, and maintainable solutions. You'll contribute to architecture and technical planning, help drive application modernization initiatives, and use AI-powered development tools to improve engineering productivity, software quality, and delivery speed.

You’ll thrive in this role if you enjoy balancing hands-on software development with technical leadership, mentoring others, and continuously improving how software is built and delivered.

What You'll Do

Design, develop, maintain, and support enterprise applications, scalable web applications, REST APIs, and system integrations.

Partner with stakeholders to translate business requirements into secure, reliable, and maintainable technical solutions.

Participate in architecture discussions, design reviews, and technical planning while contributing to application modernization and digital transformation initiatives.

Troubleshoot production issues, support releases and deployments, and implement sustainable solutions that improve system reliability and performance.

Drive automation, engineering best practices, secure software development, and continuous improvement across the software development lifecycle.

Mentor team members, provide technical leadership, and collaborate with global teams to deliver high-quality software solutions.

Leverage AI-powered development tools to accelerate development, testing, debugging, documentation, code reviews, and overall developer productivity.

What You'll Bring

Bachelor's degree in Computer Science, Engineering, Information Technology, or a related field, with 8-12+ years of enterprise software development experience.

Strong expertise in C#, .NET/.NET Core, REST API development, and modern web application development.

Deep knowledge of Microsoft SQL Server, including database design, stored procedures, views, indexing, query optimization, performance tuning, and database maintenance.

Experience supporting business-critical applications, including IIS administration, deployments, production support, and operational excellence.

Strong understanding of Agile/Scrum methodologies, software development lifecycle practices, source control, CI/CD pipelines, and secure coding principles.

Proven ability to solve complex enterprise-scale technical challenges while effectively communicating and collaborating with technical and non-technical stakeholders.

Hands-on experience using AI-assisted development tools such as GitHub Copilot, Claude Code, or similar platforms to improve software quality, delivery speed, and engineering productivity.

Passion for innovation, modernization, continuous improvement, and mentoring others.

Nice to Have

Experience with HTML, CSS, JavaScript, Python scripting, and automation.

Experience working with content management systems (CMS).

Exposure to cloud platforms, modern application architectures, and application modernization initiatives.

Experience within Financial Services, Capital Markets, FinTech, or other regulated industries.

Exposure to AI-enabled business solutions and workflow automation.

This position will be located in Toronto and offers the opportunity for a hybrid work environment at least 3 days a week in-office, subject to change, providing flexibility and accessibility for qualified candidates.
