Lead by example through thorough code reviews, championing best practices in clean architecture, modularity, and performance optimization.
Help onboard new developers, provide thoughtful feedback, and support the growth of team members through collaboration and technical guidance.
Maintain clear, comprehensive technical documentation for APIs, services, and architectural decisions.

Requirements

Experience: 8+ years of experience, with a strong track record of building and scaling Django based applications. Familiarity with running Python services on constrained environments (e.g., x86 NUCs, Raspberry Pi, etc.).
Python & Django: Deep expertise in modern Django architecture and Python development. Comfortable with asynchronous tasks, REST APIs, and integrations.
Databases: Proficient in PostgreSQL and SQLite, with a strong understanding of efficient ORM usage and performance-aware query design.
