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.
