We’re looking for our next Principal Software Engineer. Could it be you?
Reporting to the Manager, Software Engineering.
At Flexiti Financial, we're building the next generation of financial technology — and we need a seasoned engineer who thrives at the intersection of complex system design, application and solution architecture, and cross-team technical collaboration. This role is directly responsible for providing strategic technical guidance, hands-on architecture, and active contribution to the codebase across our most complex engineering challenges.
The principal challenges of this position are to lead the research, architecture, and implementation of Web applications, APIs, and Cloud Native systems; to deeply understand business needs and translate them into scalable, secure, and robust solutions; and to establish engineering standards and best practices that elevate the entire organization.
This is a great fit for an out-of-the-box thinker who is passionate about cutting-edge technology, leverages AI to work smarter and faster, communicates clearly with both technical and non-technical stakeholders, and wants to make a meaningful impact on next-generation financial software.

Architecture & Technical Leadership
Lead the research, solution architecture, and implementation of Web applications, Mobile applications, APIs, and Cloud Native systems for Flexiti's proprietary platforms. Work with technical leads and enterprise architects to design software solutions, including technology selection, technical direction setting, estimation, and planning. Translate business requirements into specific solutions, applications, and process designs — ensuring scalability, security, and performance at every layer. Write technical and design documents for proposed solutions and own the end-to-end integration of solution components, on time and on budget. Work on technical POCs to validate technology choices and lead them through to selection and implementation. Ensure consistency of design elements across individual components, services, modules, and applications. Lead implementation of Microservices using multiple languages and cloud native best practices.
AI Integration & Adoption
Design and architect solutions that incorporate AI/ML capabilities, including integration of AI APIs (e.g., OpenAI, Azure AI) into existing and new products. Champion the adoption of AI-powered development tools (e.g., GitHub Copilot, Claude, Cursor) across engineering teams, establishing best practices for their effective use. Evaluate emerging AI technologies and assess their applicability to Flexiti's engineering roadmap and product needs. Mentor and guide engineers on incorporating AI into their daily workflows to improve productivity, code quality, and delivery speed.
Collaboration & Standards
Collaborate with cross-functional technology teams to solve complex problems and enable new architecture patterns. Play an active role in defining standards and guidelines around Scalability, Security, Logging, Auditing, Policy Management, Performance Monitoring, and KPIs. Propose and implement best practices, quality standards, and delivery methodologies in partnership with architects and engineers across the organization. Provide technical screening for new team members and assist in preparing roadmaps and strategy for the engineering department.

AI & Innovation
Hands-on experience leveraging AI tools (e.g., GitHub Copilot, Claude, Cursor, or similar) to improve development productivity and code quality. Practical experience designing or architecting solutions that incorporate AI/ML capabilities or integrate AI APIs (e.g., OpenAI, Azure AI). Demonstrated ability to evaluate emerging technologies and drive their adoption within engineering teams.
Architecture & Design
Experience with all aspects of the system implementation process: requirements gathering, solution design, development, testing, and post-implementation support. Strong knowledge of integration design patterns, Web Services standards, and the ability to formulate and defend solutions in architecture committee settings. Has strong experience in Application Integration Architecture, Domain Driven Design, Solution Design, and Development using Microservices architecture. In-depth experience using Agile and Scrum methodologies in iterative development environments.

Excellent interpersonal, verbal, and written communication skills — comfortable interacting with stakeholders at all levels, from engineers to business executives. Proven ability to work across multiple teams, facilitate technical discussions, and build consensus on complex architectural decisions. Strong documentation, analytical, and problem-solving skills.
Compensation Information
Base salary range: $114,000 - $142,000 The final compensation package will be commensurate with the successful candidate's experience, skills, and geographic location (Canada). It includes a comprehensive benefits plan and a competitive incentive (bonus) program for Full-Time Permanent roles.
