Location: Toronto, ON (Onsite at 222 Jarvis St., 7.25 hours per day between 8:00 AM and 5:00 PM)
Duration: 10-month contract
Advantages
End-to-End Logic Ownership: Command full technical control over server-side logic execution, database structures, and backend data-interchange pathways.
Balanced Full-Stack Exposure: Expand your engineering reach by integrating highly interactive, design-driven frontend modules with deep transactional database engines.
Strategic Infrastructure Visibility: Steer critical performance-tuning initiatives and runtime data conversions for a major enterprise infrastructure project.
Structured Workspace Routine: Benefit from a highly reliable, standard daytime framework located at a central, accessible downtown professional workspace.
Responsibilities
Server-Side Application Engineering: Translate high-level systems design specifications into working, fully tested applications. Author detailed programming specifications, write clean compiled code, and execute rigorous unit testing matrices.
API Development & System Architecture: Design, build, and maintain robust, scalable backend RESTful API web services to manage the secure, high-performance interchange of data between server ecosystems and end-user platforms.
Database & Information Governance: Lead the structural definition, modeling, optimization, and maintenance of centralized relational and hierarchical database technologies, maximizing query responsiveness.
Frontend Component Integration: Collaborate with client-side engineers to seamlessly integrate user-facing presentation layouts and modern client-side design components into the broader application architecture.
Tier-3 Operations & Problem Solving: Diagnose, isolate, and resolve complex application and database bottlenecks arising during system use, runtime operations, data conversions, or structural environment migrations.
Lifecycle DevOps & Automation: Support integration tracks by reviewing, analyzing, and modifying product installation scripts, automation routines, and backend data middleware configurations.
Agile Stakeholder Consultation: Participate actively in project walkthroughs, sprint reviews, and architectural design sessions under Rapid Application Development (RAD) and Agile frameworks, generating detailed technical and system documentation.

Core Backend Seniority: 8+ years of progressive professional experience navigating the entire Software Development Life Cycle (SDLC) within complex, multi-tiered enterprise application environments.
API Engineering Expertise: Proven, hands-on master-level experience designing, developing, and securing backend (API) integration layers and communication protocols.
Frontend Ecosystem Literacy: Demonstrated experience developing and connecting web applications utilizing Angular frameworks paired with clean, accessible component principles like Material Design.
Database & Query Performance Skills: Advanced practical knowledge of relational database management systems (RDBMS), information retrieval packages, and optimization using structured query languages.
Technical Design & Tooling: Strong capability utilizing structured object-oriented methodologies, modern software design patterns, middleware components, and installation scripting tools.
Communication & Collaboration: Outstanding verbal, written, and consultative communication skills, with a proven track record of facilitating technical design sessions and clarifying specs for cross-functional project teams.
Nice to Have:
Prior professional software engineering experience operating within a Canadian public sector framework or government I&IT delivery branch.
