Job description

Senior Software Engineer

About Paramount Commerce

We are Paramount Commerce, a leading fintech company focused on simplifying payments in Canada. Since the early 2000s, we have redefined online purchasing by introducing a way to pay directly from a bank account, bypassing credit cards or e-wallets. Our commitment is to provide the highest standards of security and risk management that support seamless payments and rich data.

As we strengthen our position in Canada, we are strategically positioning ourselves for global expansion. To achieve our goals, we are seeking talented professionals who can push the boundaries of innovation, contributing to our growth across Canada and worldwide.

Opportunity

We're on the lookout for a Senior Software Engineer to join our dedicated, team-oriented, and geographically diverse group. Your mission is to personally build and deliver the robust, scalable systems that define our merchant platform. This isn't just about closing tickets; it's about owning complex features from design to deployment and architecting the future of our merchant-facing technology.

What You'll Do

• End-to-End Feature Ownership: Design, build, and deliver complex, high-impact features for the merchant platform. You'll work from ambiguity, collaborating with Product to define scope, and own 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 innovation with reliability.
• Code & Quality Excellence: Champion high 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.
• 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 documents, GitHub, and Slack, and fostering a collaborative environment of learning.

Who You Are

• A Seasoned Engineer: You have 7+ years of professional software development experience.
• A Tech-Forward Builder: You're proficient with our core technologies (Java, GO, React) and database systems (PostgreSQL). You're also comfortable in our cloud environment (AWS and GCP) and familiarity with Kubernetes is a plus.
• An Asynchronous Communicator: You are a strong written communicator who excels in a remote, distributed, and asynchronous work culture. You document your work and communicate with clarity.
• A Systems Thinker: You have experience and a strong interest in building, operating, and maintaining scalable distributed services. You think about high availability, performance, and reliability when you design.
• A Quality-Driven Collaborator: You have high standards for your work and others'. You are skilled in practices like TDD, profiling, and debugging, and you enjoy collaborative work like pairing.
• A Proactive Problem-Solver: You are comfortable working autonomously, picking up new work, and engaging in problem-solving discussions to find the best solution.

Why Paramount Commerce?

• Generous Vacation & Summer Fridays
• Health & Dental Benefits from Day 1
• Wellness Spending Account
• Retirement savings matching plan
• Remote / Hybrid work (Thursdays in office for GTA team)
• Birthday Day Off
