Full job description

We are seeking an experienced Senior Software Developer - Full Stack to lead the technical design, implementation, and expansion of scalable enterprise web applications. In this role, you will bridge modern front-end user interfaces with complex multi-language back-end microservices, leveraging Next.js/React alongside Python (FastAPI) and .NET Core (C#). Operating across cloud-native architectures, relational/NoSQL databases, and automated pipelines, you will drive full-stack development, build reusable UI components, engineer RESTful APIs, and establish software engineering standards within a fast-paced Agile environment.

Location: Toronto, ON (Fully Onsite – 5 days/week required)

Duration: 7-month contract.

Advantages
Cutting-Edge Stack: Hands-on development across Next.js, React, FastAPI (Python), .NET Core (C#), and Azure cloud services.

High Technical Ownership: Direct architectural impact across microservices, serverless components, and testable UI design.

Advanced Technology Integration: Opportunity to work in an environment leveraging machine learning and computer vision capabilities.

Structured Onsite Synergy: Collaborate directly with senior developers and technical leads in a 5-day onsite workspace.

Responsibilities
Full-Stack Application Development: Architect, build, and maintain responsive front-end interfaces using Next.js, React.js, and Node.js while engineering back-end services using Python (FastAPI) and .NET Core (C#).

API & Microservices Engineering: Design, construct, and secure RESTful APIs and Web API services, integrating front-end user interactions seamlessly with underlying database systems.

Database Management & Data Pipelines: Design, optimize, and expand database architectures (Azure SQL Server, Cosmos DB, Redis) and automated ETL pipelines for data extraction, transformation, and loading.

Security & Authentication Implementation: Enforce application security standards, OAuth 2.0 protocols, JWT authentication, session management, and secure key management using Azure Key Vault.

Architecture & Component Design: Own solution design across microservices, serverless patterns, and UI layers, creating reusable, testable components and responsive design layouts.

DevOps & Container Deployment: Manage CI/CD automation pipelines, application packaging, and container-based deployments using Azure DevOps.

Testing & Technical Troubleshooting: Conduct unit testing, debug complex technical issues throughout migration and deployment phases, and mentor team members to promote technical excellence.

Qualifications
React & Next.js Mastery: Advanced, hands-on proficiency developing web applications using Next.js, React.js, and Node.js (Strictly Required).

Python & FastAPI Expertise: Strong proficiency in modern Python development with a proven track record of designing and building RESTful APIs using FastAPI (Strictly Required).

.NET Core & C# Seniority: Proven expertise developing .NET Core Services, Web APIs, and back-end logic using C# (Strictly Required).

Responsive & Testable UI Architecture: Advanced knowledge of UI design, responsive design patterns, and testable front-end architecture (Strictly Required).

Database Engineering: Expert-level experience with MS Azure SQL Server (stored procedures, query optimization, encryption) as well as Cosmos DB and Redis cache.

Security & Auth Protocols: Demonstrated experience implementing OAuth 2.0, JWT authentication, Web Security, and session management.

DevOps & Cloud Tools: Hands-on working knowledge of Azure DevOps pipelines, containerized deployments, and cloud platform services.

Nice to Have:
3+ years of experience working with machine learning models, specifically in computer vision (e.g., OpenCV, PyTorch, TensorFlow).
