Contribute to software architecture and API design decisions, balancing performance, security, scalability, and maintainability.
Develop and maintain cloud-native services using Kubernetes and cloud technologies.
Write clean, maintainable, well-tested code and contribute to automated testing, CI/CD, and code reviews.
Collaborate with developers, technical leads, and cross-functional engineering teams to deliver high-quality software.
Provide technical guidance and mentorship to other developers while fostering a collaborative engineering environment.
Leverage AI-assisted development tools where appropriate, maintaining strong engineering judgment and code quality.
Occasionally contribute to frontend development using React and TypeScript.

Skills and Qualifications

At least 2 years of professional Python development experience, preferably as a primary backend language.
Strong hands-on experience designing, developing, and maintaining RESTful APIs in production environments.
Solid understanding of microservices architecture, distributed systems, service-to-service communication, and integrations.
Experience developing backend services within complex, interconnected software platforms.
Experience with cloud platforms such as AWS, Azure, or GCP.
Hands-on experience with Kubernetes, containerization, and cloud-native development.
Strong knowledge of software architecture, system performance, scalability, troubleshooting, and optimization.
Experience with automated testing, CI/CD pipelines, code reviews, and modern software development practices.
Ability to independently solve complex technical problems, evaluate architectural trade-offs, and deliver reliable solutions.
Strong communication and collaboration skills, with experience mentoring developers and working across engineering teams.
Experience working in established engineering environments with structured development processes and cross-functional collaboration.

Nice to Have

Experience with FastAPI or similar Python frameworks.
