  • Participate in agile ceremonies, contribute to RFC/ADR documentation, and perform peer code reviews to maintain high engineering standards.

  • Enhance observability and reliability of applications/components by implementing logging, metrics, tracing, dashboards, and alerting that support incident triage, rootcause analysis, and continuous improvement.

  • Hands-on experience in building and deploying web applications, Python-based backend APIs and major cloud infrastructures (AWS, GCP, or Azure).

  • 7+ years of relevant professional experience in software development.

  • Experience with some of the following: FastAPI, SQLAlchemy, Pydantic, Celery.

  • Practical experience with containerization and orchestration (Docker, Kubernetes) and familiarity with CI/CD and DevOps practices and tools (Github Actions, Git-based workflows).

  • Strong foundation in Algorithms, Data Structures, and performance optimization techniques for scalable applications.

  • Experience with relational databases (like Postgres) and familiarity with NoSQL databases (like Redis) is an advantage.

  • Proactive mindset for learning new technologies, robust work ethic, commitment to resolving technical challenges, and responsibility.

  • Excellent communication skills with the ability to articulate technical concepts.

  • Exposure to Large Language Models (LLMs) and AI development tools (Claude, Copilot).

  • Data engineering background or interest, familiarity with NumPy, pandas, Polars is a plus.

  • Experience with full-stack development with Typescript and React is a plus.
