Job description

Become a digital, global citizen and enable the new generation of digital entrepreneurs around the world. AppDirect offers a subscription commerce platform to sell any product, through any channel, on any device - as a service. We power millions of subscriptions worldwide for organizations. We do this by our values-driven culture—one that enables you to Be Seen, Be Yourself, and Do Your Best Work.

About You

We are looking to hire a skilled and ambitious Senior Software Developer in Montreal. You are a highly technical, hands-on PHP developer with a passion for producing maintainable and robust code? You’re passionate about driving value through innovative solutions and enjoy working in a collaborative environment? We’d love to have you on board!

What you’ll do and how you’ll have an impact

• You will help shape and evolve the ecosystem for integration into our platform as we scale with more use cases and areas of extensibility;
• Architect and build systems that can process a high volume of transactions;
• Design, implement, and support scalable fault tolerant systems to minimise customer impact in case of failures;
• Participate in the effort to move to a micro-service oriented architecture;

What we’re looking for

• Written/Spoken French and English;
• Knowledge of web service technologies and building REST and GraphQL APIs;
• Enjoy building production grade code then supporting and maintaining once it goes live;
• You own features end-to-end across the stack and know when to go deep yourself versus partnering with specialists. We expect solid, production-grade fundamentals in infra, backend, data, frontend, and delivery, with the judgment to make trade-offs, unblock others, and raise the bar on how the team ships. Not deep expertise in every layer on every task.
• L2–L3 AI-assisted development: daily use of coding agents for bounded tasks with review (L2), and routine delegation of feature-sized work (L3), with you owning design intent, test strategy, and merge quality.
• Proven track record of delivering end to end business solutions;
• 5 years of relevant experience;

At AppDirect, we believe that innovation thrives in an environment that houses diversity of excellence, experience and thought. We respect each AppDirector as their own fingerprint; unique with no one alike. We foster an environment of inclusion without regard to race, religion, age, sexual orientation, or gender identity enabling AppDirectors to embrace their uniqueness to do their best work.
