• Join a technical founding team with a working product already featuring multiple modes (translate, share, connect, meet) ready for production-grade scaling.

What you will do

• Architect and maintain a unified AI API platform to package internal capabilities for high-scale external use cases.
• Design and implement critical backend systems for billing, usage metering, and complex real-time voice room infrastructure.
• Build and optimize high-concurrency data pipelines and cloud infrastructure on Azure, incorporating automated scaling and load balancing.

The ideal candidate

• 4-8 years of experience building and scaling production-grade backend systems with a high degree of autonomy and technical ownership.
• Strong proficiency in Python and solid experience with distributed systems, cloud infrastructure (specifically Azure), and database design.
• Experience with real-time systems and high-concurrency design, with the ability to build monitoring and analytics dashboards from scratch.
