Build and maintain frontend functionality using a server-rendered technology stack, including Jinja2, Bootstrap, JavaScript/jQuery, and Webpack . Design, implement, and maintain REST APIs and integrations with external systems and services. Own assigned work end-to-end, from understanding requirements and implementation through delivery and follow-up.

Proven production experience with Python and Flask , including SQLAlchemy or a comparable ORM. Strong experience with relational databases, particularly MySQL or MariaDB . Frontend development experience with Jinja2 templates, Bootstrap, JavaScript/jQuery, and Webpack , rather than relying exclusively on modern SPA frameworks.

Experience working in consulting, professional services, IT services, outsourcing, or another client-facing environment is strongly preferred.
