Full job description

Senior Front-End Developer - contract

We seek a Senior Front-End Developer to join the Aequilibrium team as a contractor, working with our top global clients in the credit union, banking, or fintech sectors. You will be a key contributor to the development of innovative, high-scale financial and banking applications. The ideal candidate is a polyglot engineer who is equally comfortable architecting a Java microservice, optimizing a .NET Core backend, or building a high-performance React frontend.

What you will be doing:

End-to-End Delivery: Build, develop, and maintain complex, responsive web applications from the ground up using a variety of modern stacks.
Architectural Leadership: Design and implement modular, scalable, and reusable code structures that serve as the foundation for future development.
Cross-Stack Integration: Collaborate with distributed teams to integrate diverse APIs and services (Java, .NET, Node.js), ensuring seamless data flow and system reliability.
UI/UX Translation: Transform high-fidelity prototypes into performant, accessible, and pixel-perfect code.
Performance Engineering: Optimize application performance across the entire stack, ensuring sub-second response times and cross-browser consistency.
Mentorship & Quality: Lead code reviews, establish best practices, and mentor intermediate developers to elevate the team's technical bar.
Agile Excellence: Drive continuous improvement within an Agile/SCRUM environment, participating in all ceremonies and contributing to process evolution.

Must Have:

Seniority: 10+ years of professional experience in Full-Stack development, with at least 3 years in a Senior or Lead capacity.
The "Triple Threat" Backend: Proven, recent experience developing production-grade applications in Java (Spring Boot), .NET (C# / .NET Core), and Node.js.
Frontend Mastery: Expert-level proficiency in React.js (Fluency is mandatory), TypeScript, HTML5, and CSS3 (Sass/LESS).
Modern Web Standards: 5+ years of deep experience with TypeScript and Python.
Cloud Native: Hands-on experience with Azure backend systems and/or C# backends, including integration with Azure App Services, Functions, and Key Vault.
API Design: Solid understanding of RESTful APIs and GraphQL; experience designing contracts that bridge diverse backend ecosystems.
Testing Rigor: Extensive experience with testing frameworks (Jest, Mocha, xUnit, JUnit) and a "test-first" development mindset.
Professional Services: Experience working in the Professional Services / Consulting industry, managing client expectations and navigating high-ambiguity projects.
Education: Bachelor’s Degree in Computer Science, Software Engineering, or a related technical field.
Status: Canadian resident with Citizenship or PR Status.

Nice to Have:

Fintech Expertise: Direct experience working with Credit Unions, Banking, or Fintech platforms.
Multi-Cloud: Experience deploying and managing applications across AWS and GCP in addition to Azure.
Mobile: Familiarity with React Native or native mobile development.

Location
This is a 100% full-time remote position. Candidates residing outside of Canada will be required to work with us as independent contractors.

Compensation
The hourly rate for this position ranges from CAD $ 60/h to $90/h. The salary/rate offered will be based on geography, skills, and experience.
