• Optimize database performance and ensure data integrity.
• Write and optimize database queries.
• API Development and Integration:
• Develop and maintain RESTful or GraphQL APIs.
• Integrate third-party APIs and services.
• Ensure API security and reliability.
• System Architecture:
• Contribute to the design and architecture of backend systems.
• Ensure scalability, performance, and reliability of applications.
• Troubleshoot and resolve system issues.
• Testing and Debugging:
• Write unit and integration tests.
• Debug and resolve code errors and performance bottlenecks.
• Participate in code reviews.

Key Responsibilities:

• Design, implement, and maintain server-side applications, APIs, and databases.
• Collaborate with front-end developers to integrate user-facing elements with server-side logic.
• Develop RESTful APIs, GraphQL, or other web services that integrate with databases and external services.
• Write clean, efficient, and reusable code while following best practices for backend development.
• Optimize applications for speed and scalability.
• Ensure the security of applications, databases, and data handling practices.
• Troubleshoot and debug issues in production and development environments.
• Write unit and integration tests to ensure the reliability and stability of the backend code.
• Work with databases (SQL or NoSQL) and optimize database queries for performance.
• Implement caching mechanisms to improve application performance.
• 
  

• Write code and tests, build prototypes, resolve issues, and profile and analyze bottlenecks
• Design robust APIs to support mobile and desktop clients
• Manage and optimize scalable distributed systems in the cloud
• Optimize web applications for performance and scalability
• Develop automated tests to ensure business needs are met, and allow for regression testing

Required skills and qualifications

• Excellent foundation in computer science, algorithms, and web design
• Experience in writing highly secure web applications
• Experience with core AWS web-enabling technologies
• Growth mindset that challenges the status quo and focuses on outside-the-box ideas and solutions

Preferred skills and qualifications

• Bachelor’s degree (or equivalent) in computer science
• Experience in designing RESTful APIs, specifically for mobile apps

What we’re looking for:

· Amazing technical instincts. You know how to evaluate and choose the right technology and approach for the job. You have stories you could share about what problem you thought you were solving at first, but through testing and iteration, came to solve a much bigger and better problem that resulted in positive outcomes all-around.

· A love for learning. Technology is continually evolving around us, and you want to keep up to date to ensure we are using the right tech at the right time.

· A love for working in ambiguity—and making sense of it. You can take in a lot of disparate information and find common themes, recommend clear paths forward and iterate along the way.
