Role Overview:

We are looking for a mid-level backend developer who can work independently on integrations, understand existing systems and business logic, and take ownership of problems from investigation through implementation and resolution.

Key Responsibilities:

• Understand and work with our existing Django/Python architecture, codebase, and business logic.
• Design, develop, test, and maintain third-party API integrations and integration modules.
• Work with APIs, authentication, webhooks, data synchronization, error handling, rate limits, retries, and other integration challenges.
• Investigate and resolve issues reported by users or identified internally, with a focus on finding and fixing the root cause.
• Build solutions that are secure, reliable, efficient, scalable, and maintainable.
• Write clean, well-structured code and maintain appropriate documentation, tests, and code reviews.
• Work closely with the core team to understand requirements, identify edge cases, and recommend practical technical solutions.
• Identify opportunities to improve existing systems, integrations, performance, reliability, and development practices.

Required Qualifications:

• 2 - 5 years of professional software development experience, with strong hands-on experience in Python and Django.
• Strong experience working with REST APIs and third-party integrations.
• Practical experience with API authentication, including OAuth and token-based authentication.
• Experience working with webhooks, API rate limits, pagination, retries, error handling, and data synchronization.
• Solid understanding of relational databases and ORMs, preferably Django ORM.
• Experience integrating with at least one e-commerce platform such as Shopify, Amazon, eBay, or WooCommerce.
• Strong debugging and problem-solving skills, with the ability to independently investigate unfamiliar issues.
• Good understanding of secure coding practices, authentication, authorization, and protection of sensitive data.
• Strong written and verbal communication skills.

What We Value:

• Take ownership instead of waiting for instructions.
• Think about the actual problem and its root cause.
• Are comfortable investigating and solving unfamiliar problems independently.
• Continuously learn and improve technical skills.
• Care about the quality and reliability of what you build.
• Are willing to experiment, make mistakes, learn, and improve.
