About The Role

The Senior Software Engineer is responsible for designing, developing, testing, deploying, and supporting production-grade software products and shared platform capabilities within DNV’s Digital & Transformation organization. This role sits within the Application Engineering section and contributes to the development and modernization of scalable web applications that support digital delivery across Energy Systems.

This role sits within the Digital & Transformation organization, helping to advance how DNV performs Due Diligence, Verification & Assurance, and Renewables Certification work across Energy Systems.

This is not a project-based delivery or staff-augmentation role. Engineers are expected to develop deep product knowledge and remain accountable for the quality, maintainability, and operation of the software they build.

Working in close partnership with Product leadership, Data & AI Engineering, Solution Engineering, Platform Reliability, Solution Architecture, and Platform Security & Compliance, this role helps bring application capabilities, data services, AI-enabled features, workflows, and APIs into one cohesive platform and product experience.

The Senior Software Engineer designs, builds, tests, deploys, and supports scalable software across a modern full-stack, multi-cloud environment. The primary application stack includes Python, Django, TypeScript, React, and related web technologies, with cloud services spanning both AWS and Microsoft Azure. The role requires strong engineering fundamentals, practical cloud experience, and the ability to collaborate effectively across globally distributed teams.

This role supports custom software development, application modernization, and integration with low-code or hybrid development environments, helping establish shared patterns, APIs, reusable components, and maintainable application architecture across the platform.

This position can be located in our Toronto office, presenting a dynamic hybrid schedule where employees will typically spend three (3) days per week working from either a DNV office or client location/site. Further details regarding role-specific requirements will be shared during the interview process**

What You'll Do

Software Engineering & Delivery

• Design, develop, test, and maintain scalable application and platform capabilities using modern software engineering practices.
• Build cohesive product experiences across web applications, backend services, APIs, user interfaces, and platform integrations.
• Work directly with Product and Architecture stakeholders to shape requirements, evaluate technical approaches, and translate product direction into maintainable, production-ready software.
• Participate actively in code reviews, technical design discussions, estimation, delivery planning, and implementation decisions.
• Write clean, well-structured, testable, and maintainable code that supports long-term product quality and team velocity.
• Own product capabilities through design, implementation, deployment, monitoring, maintenance, and iterative improvement rather than treating delivery as complete when the initial feature is released.

Full-Stack Application Development

• Develop modern full-stack product capabilities using Python, Django, TypeScript, React, and related frontend and backend technologies.
• Build responsive, reusable, and accessible frontend experiences using TypeScript and React, integrated with secure, scalable, and maintainable backend services and APIs built using Python and Django.
• Support application
