• Write and maintain automated test suites and support CI/CD deployment pipelines.
• Contribute to system design decisions, ensuring alignment between backend services and infrastructure requirements.

Requirements:

• 6+ years of experience developing and scaling backend systems using Python.
• Strong experience with distributed systems and backend architecture design (event-driven systems, queues, workers, schedulers).
• Solid understanding of databases such as PostgreSQL, MySQL, Redis, and messaging systems like Kafka, RabbitMQ, SQS, or Pub/Sub.
• Hands-on experience designing, implementing, and maintaining API services at scale.
• Proven ability to lead complex feature development in enterprise SaaS environments.
• Strong experience optimizing asynchronous processing systems (e.g., Celery or equivalent).
• Experience owning systems end-to-end, including awareness of infrastructure and deployment considerations.
• Strong communication skills with the ability to document systems, explain trade-offs, and influence technical direction.

Benefits:

• Competitive base salary ranging from $130,000 to $180,000 CAD, with higher potential for Staff-level candidates.
• Equity or stock options as part of the compensation package.
• Comprehensive health and medical benefits.
