Location: Toronto Ontario - Onsite Education: Bachelor’s or Master’s degree Experience: 5–10+ years (backend-focused) In person Interview in Toronto is MANDATORY.

Job Overview The primary focus of this role will be to design, build, and maintain the EMFI Data Application Platform, a financial analytics application. The incumbent will work across the full stack to deliver reliable, performant, and secure data products. Responsibilities and Duties • Collaborate with internal stakeholders to translate business and analytical requirements into well-defined backend features and data products. • Design and deploy scalable microservices within the FastAPI ecosystem, establishing clear service boundaries for domain-specific services and ensuring loose coupling through well-defined API contracts. • Design and develop Snowflake-native applications including Snowpark (Python), stored procedures, tasks, streams, and dynamic tables to support day-end processing engines that run natively within the Snowflake compute layer. • Design and implement RESTful API endpoints using FastAPI ensuring data contracts are clearly defined, versioned, and documented via OpenAPI/Swagger. • Write and optimize SQL queries against Snowflake and PostgreSQL for reporting, aggregation, and analytical use cases. • Own end-to-end feature delivery: from requirements gathering and API contract definition through implementation, testing, and deployment. • Ensure platform security by applying best practices around authentication, authorization (RBAC), input validation, and safe error handling, aligned with OWASP Top 10.

Technical Skills • Experience designing and implementing microservices architectures, including service discovery, inter-service communication, API versioning, and distributed tracing/logging for observability. • Proficiency in Python for backend development, including FastAPI async patterns, and Pydantic-based data validation. • Hands-on experience with SQL and analytical databases for writing optimized queries, aggregations, and data transformations. • Experience developing Snowflake-native applications: stored procedures (JavaScript/Python), Tasks, Streams, Dynamic Tables, and Snowpark for building backend processing engines. • Understanding of REST API design, OpenAPI specifications, and API integration patterns in frontend applications. • Knowledge of authentication and authorization patterns including JWT, OAuth2, and role-based access control. • Experience with Docker and Docker Compose for local development and containerized deployments. • Familiarity with CI/CD pipelines for automated testing and deployment. • Experience with version control using Git, including branching strategies and code review workflows. • Ability to work with cloud platforms (AWS, Azure, or GCP) for data storage, compute, and deployment.

Qualifications and Skills • Bachelor’s degree (Master’s preferred) in Computer Science, Software Engineering, Information Systems, or a related discipline. • 5-7 years of professional full stack development experience, with demonstrated delivery of production-grade web applications. • Experience in the Payments or Fintech industry would be a strong asset. • Proven ability to work independently, manage multiple concurrent workstreams, and deliver with minimal oversight. • Excellent communication and interpersonal skills, with the ability to engage both technical and non-technical audiences. • Unquestionable personal and business ethics and integrity.
