Senior Software Engineer, Payment Experience / Développeur(euse) logiciel sénior

Overview

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

• A Seasoned Engineer: 8+ years of professional software engineering experience
• A Distributed Systems Engineer: You have deep experience designing, building, and operating scalable distributed services. You naturally think about reliability, performance, and availability
• Strong in Go & Kubernetes: You\'re comfortable working in Go and in containerized, cloud-based environments. Experience with Kubernetes and modern infrastructure is important
• Fintech or Payments Experience: You bring experience in financial systems, fintech, or a strong understanding of how payments flow (ideally within Canada), and the care required when building in regulated, high stakes environments
• Full-Lifecycle Owner: You\'re a T-shaped engineer who enjoys working across the full lifecycle, from design and implementation through deployment, monitoring, and iteration
• Drive Results: You take full accountability and responsibility for your area of ownership. You like to directly drive your projects and take a high level of pride in your results.
• Business Minded & Customer Centric: You have a healthy dose of business acumen and a deep understanding of how customers use products. You understand how technical decisions impact real people and real outcomes
• Comfortable with Trade Offs: You can balance speed, quality, and complexity, and make thoughtful decisions in ambiguous situations
• Level-Headed & Grounded: You bring calm to complexity. You\'re confident without ego, motivated, and steady in fast-paced environments
• Strong Opinions, Loosely Held: You care deeply about doing great work, advocate for your ideas, and are equally open to new perspectives. You know how to disagree and commit in perpetuity
• Data Informed Thinker: You like to quantify impact, use data to guide decisions, and measure outcomes
• Highly Collaborative & a Self-Starter: You work well with others, think ahead, take initiative, and consider the broader impact of your work on the system and the business
