• Leverage Google Cloud Platform (GCP) for hosting, storage, and deployment.
• Mentor junior developers and promote best practices in coding, testing, and deployment.
• Adapt quickly to changing requirements and user feedback.
• Participate in code reviews, architecture discussions, and sprint planning.

Qualifications

• Bachelor’s degree in Computer Science, Software Engineering, Mathematics, or related field.
• 5+ years of professional experience delivering full-stack features in a SaaS environment.
• Extensive experience with Type Script, Node.js, React, and MongoDB.
• Strong backend experience with Python and FastAPI.
• Experience deploying and scaling applications on Google Cloud Platform.
• Proven ability to work in fast-paced, startup-like environments.
• Strong problem-solving skills, attention to detail, and a growth mindset.
• Excellent communication skills and the ability to collaborate across teams.
• Passion for sustainability and building impactful products.

Good to Have
