• Architect and develop scalable APIs and microservices deployed on AWS, Azure, or GCP
• Take ownership of complex features from design through to production and ongoing operation
• Drive architectural discussions and contribute to long-term technical strategy
• Collaborate with cross-functional teams to deliver secure, privacy-compliant features aligned with regulations (e.g., GDPR, BIPA, CCPA)
• Mentor engineers through code reviews, pairing, and technical guidance
• Improve system reliability, scalability, observability, and performance
• Partner with product and UX teams to deliver high-quality, user-centric experiences
• Champion secure coding practices and contribute to identity and cryptographic systems
• Identify and implement improvements to engineering practices, tools, and workflows
   

Key Projects You’ll Support
