The Role

As a Senior Fullstack Developer, you will take ownership of complex, end-to-end development features across our platform. You'll work across the stack from data models and APIs to the React interfaces that consume them. You will play a key role in architectural decisions as we continue to scale up a client-diverse, enterprise-grade product that serves regulated industries.

This is an hybrid role working 2-3 days in our Richmond Hill office.

Key Responsibilities

Design, build, and maintain fullstack features spanning backend services (.NET Framework, ASP.NET Core, ASP.NET MVC) and frontend applications (React.js)
Architect and implement GraphQL APIs using Hot Chocolate, alongside traditional REST/Web APIs, ensuring performant and well-documented interfaces for internal and external consumers
Design and optimize MSSQL database schemas, queries, and stored procedures for performance, reliability, and data integrity
Collaborate with product managers, designers, and other engineers to translate requirements into technical designs and shippable features
Own features from planning through deployment, including code reviews, testing, and production support
Identify and address technical debt, performance bottlenecks, and scalability constraints across the stack
Mentor junior and mid-level developers, providing technical guidance and code review feedback
Participate in architectural discussions and contribute to technical roadmap planning
Write clean, maintainable, well-tested code and contribute to evolving engineering standards and best practices

Skills & Experiences

Bachelor’s degree in Computer Science, Computer Engineering, or related field with 5+ years of fullstack development experience
Proven experience with .NET Framework and modern .NET (ASP.NET Core, ASP.NET MVC)
Strong hands-on experience with MSSQL (T-SQL, query optimization, indexing, stored procedures), including schema design, query optimization, and performance tuning
Solid experience developoing APIs (REST/Web APIs); experience with GraphQL, ideally using Hot Chocolate is an asset
Proficiency with React.js, JavaScript/TypeScript and modern frontend development practices
Experience working in multi-tenant or enterprise software environments is an asset
Strong understanding of software design principles, design patterns, and clean architecture

Required Technical Skills

.NET Framework, ASP.NET Core, ASP.NET MVC
MSSQL (T-SQL, query optimization, indexing, stored procedures)
GraphQL and Hot Chocolate
React.js, JavaScript/TypeScript
Web API design and development (REST and GraphQL)
Git-based version control and collaborative development workflows
Debugging and performance profiling across frontend and backend

Nice to Have Technical Skills

SSO and authentication/authorization technologies (SAML2, OAuth2, OpenID Connect)
Experience implementing ML/AI capabilities, particularly RAG (Retrieval-Augmented Generation), LLM integration, or agent-based systems
Experience with cloud platforms (AWS, Azure, or GCP)
Exposure to CI/CD pipelines and DevOps practices

What we offer

Comprehensive healthcare, dental, and vision coverage for you and family starting on first day of work
3 weeks of vacation annually

Compensation

$90,000 – $110,000 CAD per year
