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.
