Senior Software Engineer - Payment Experience

Based in Canada and headquartered in Toronto, Paramount Commerce is a fintech company focused on making payments simpler and more secure. We’ve been helping reshape online payments since the early 2000s, enabling people to pay directly from their bank accounts, without relying on credit cards or e-wallets.

Security, risk management, and reliability are at the core of what we do. We build payment solutions that are seamless, backed by strong safeguards and meaningful data.

As we continue to grow our business across Canada and prepare for expansion into new markets, we’re looking for curious, thoughtful, data driven individuals who enjoy directly solving complex problems themselves and pushing ideas from concept to execution, in a rapid iterative environment with highly capable peers. If you’re excited about building the future of payments - and want to be part of a team that’s shaping what’s next - we’d love to hear from you.

The Opportunity

We're on the lookout for a Senior Software Engineer to join our Payment Experience Engineering Team. The Payment Experience team is at the forefront of our company, owning all of the interfaces that our merchants (customers) interact with. It’s a foundational piece of our technology. This role isn't just about closing tickets and KTLO; it's about owning and driving complex features from design to deployment, and shaping the future of our customer facing technology.

What You'll Do

• End-to-End Feature Ownership : Design, build, and deliver complex, high-impact features for the merchant platform, from start to finish. You'll work from initial ambiguity, resolving and collaborating with Product to define scope and requirements, and drive your work from the initial technical design through to testing, documentation, and deployment.
• Technical Architecture & Design : Act as a key technical voice on the team. You will lead solution design discussions, architect scalable systems, write clear documentation, and make pragmatic decisions that balance iterative innovation with reliability.
• Code & Quality Excellence : Champion high SRE standards for code quality, testing, and supportability. You'll conduct thorough code reviews, provide constructive feedback, triage and debug complex issues, and participate in our on-call rotation with the rest of the team.
• Mentorship & Collaboration : Mentor and support the growth of other engineers on the team. You'll thrive in our asynchronous remote culture, communicating with clarity on GitHub, Slack, and across Google Workspace, fostering a collaborative environment of learning.

Who You Are

We’re looking for a senior engineer who blends strong technical depth and breadth with thoughtful collaboration and real world impact. This role is for someone who enjoys owning problems end-to-end, making sound trade offs, and building systems that impact and are visible directly to our customers.

If everything above doesn’t perfectly describe you, but you’re excited to learn, adapt, and grow into new areas, we’d still love to hear from you. We value curiosity, self directed learning, and people who enjoy stretching beyond what they already know.
