• Utilize Google Cloud Functions and Cloud Run to implement serverless architecture and improve application scalability.

Performance Optimization:

• Identify and resolve performance bottlenecks, ensuring that applications can scale to meet increasing demands.
• Implement efficient background processing and task queues using RabbitMQ.
• Participate in code reviews, providing and receiving feedback to maintain high-quality code and adherence to best practices.

Security:

• Ensure that backend systems adhere to best practices for security, protecting data and services from vulnerabilities.
• Implement authentication and authorization mechanisms to safeguard user data and application resources.

You are a perfect match if you have:

• Bachelor’s degree in Computer Science, Engineering, or a related field.
• 5+ years of experience in backend development, with a strong focus on web and mobile applications.
• Proficiency in Django, Nuxt (or other FE framework)
• Experience with DevOps practices and managing infrastructure on Google Cloud Platform (GCP).
• Some production DevOps Experience with Kubernetes, GitLab CI, Google Cloud Functions, or Cloud Run.
• Excellent problem-solving skills and attention to detail.
• Ability to work in a fast-paced, collaborative environment.

Preferred Qualifications: Experience with microservices architecture,knowledge of CI/CD pipelines and automated testing frameworks, and familiarity with additional cloud services and serverless architecture.

The pay range for this role is $140,000- $250,000. We offer a competitive salary package and may include variable compensation. Actual compensation is based on factors such as the candidate's location, skills, qualifications, and experience.
