Collaborate with cross-functional teams to integrate application functionality and deliver new products and process improvements.
Lead technical design and implementation, ensuring solutions align with enterprise architecture standards.
Analyze complex business and system processes to identify issues and develop innovative technical solutions.
Improve application performance, scalability, reliability, and testability through effective engineering practices.
Contribute to the transition toward smaller, modular services and fully automated CI/CD pipelines.
Establish and promote standards for coding, testing, debugging, and deployment.
Identify and implement system enhancements that improve operational efficiency and time to market.
Assess and manage technical and operational risks while ensuring compliance with applicable policies and controls.
Provide technical guidance and mentorship to mid-level developers and analysts, including coordinating development activities when required.

Required Skills and Qualifications

8+ years of experience in software application development.
Strong hands-on experience with React, JavaScript, and HTML5.
Experience with Node.js and modern web development concepts.
Strong understanding of application architecture, system integration, and software design principles.
Experience developing high-quality, testable code and troubleshooting complex application issues.
Knowledge of performance optimization, scalability, reliability, and non-functional requirements.
Experience working in large, collaborative development environments.
Familiarity with automated testing, CI/CD pipelines, and modern software delivery practices.
Demonstrated technical leadership, problem-solving, and mentoring skills.
Ability to manage competing priorities and adapt to changing business requirements.

Nice to Have

Experience with Fixed Income products, trading platforms, or capital markets applications.
Knowledge of C# and the .NET Framework.
Experience with derivatives, cash products, or securities financing transactions.
Exposure to service-oriented or microservices architectures.

Education

Bachelor’s degree in Computer Science, Software Engineering, or a related field, or equivalent practical experience.
Master’s degree is preferred.

Ideal Candidate

The ideal candidate is a hands-on senior engineer with strong React and JavaScript expertise, experience building enterprise-scale applications, and the ability to lead technical implementation. Experience in financial services or Fixed Income trading platforms is an advantage.

Please note: This role requires working onsite in Toronto three days per week.
