  • Integrate third-party services, libraries, and tools within the application architecture
  • Apply security best practices, including encryption, authentication, authorization, and mitigation of common security vulnerabilities
  • Continuously improve code quality, performance, and maintainability through thoughtful design and refactoring
  • Write comprehensive unit, integration, and end-to-end tests to ensure system reliability and stability
  • Debug and troubleshoot issues in both new and existing systems
  • Participate in code reviews, share constructive feedback, and help foster a culture of continuous improvement
  • Document code, APIs, and system architecture to support knowledge sharing and efficient onboarding
  • Set up and maintain CI/CD pipelines to automate build, test, and deployment processes

Requirements:

  • Bachelor’s degree in Computer Science, Engineering, or equivalent practical experience
  • 5+ years of experience as a backend software engineer or in a similar role
  • Proficiency in Python or Go, or experience with similar modern backend languages
  • Experience designing and implementing RESTful APIs, ideally using web frameworks such as FastAPI or Gin
  • Hands-on experience with relational databases, preferably PostgreSQL (schema design, query optimization)
  • Solid understanding of web technologies, protocols, and standards (HTTP, REST, JSON, XML)
  • Familiarity with Continuous Integration practices and tools
  • Proficient with Git and modern branching workflows
  • Comfortable working in agile environments using Jira or similar tools
  • Strong problem-solving skills, attention to detail, and debugging ability
  • Able to work effectively both independently and as part of a team
  • Experience collaborating in a remote, distributed team environment
  • Clear and proactive communication skills

Nice to have:

  • Experience with message brokers, preferably RabbitMQ
  • Experience with cloud platforms (AWS, Azure, or Google Cloud) and containerization/orchestration tools such as Docker Swarm, Nomad, or Kubernetes
  • Knowledge of API security standards, token management, and access control mechanisms (OAuth2, JWT, OpenAPI, etc.)
