Software Development Engineer

Backend/Fullstack Engineer

Who We Are

Phronetic, the artificial intelligence division of Infibeam Avenues Limited, is building the foundational platform for the "agentic economy," moving beyond simple chatbots to create an ecosystem for autonomous AI agents. Powered by Infibeam and trusted by industry leaders like Rediff, they aim to provide tools for developers to launch, manage, and monetize AI agents as "digital coworkers."

The Challenge

The current AI stack is fragmented, leading to issues with multimodal data, silent webhook failures, unpredictable token usage, and nascent agent-to-agent collaboration. Phronetic is building a unified, robust backend to resolve these issues for the developer community.

Your Mission

As a foundational member of the backend team, you will architect core systems, focusing on:

• Agent Nervous System: Designing agent-to-agent messaging, lifecycle management, and high-concurrency, low-latency communication.
• Multimodal Chaos Taming: Engineering systems to process and understand real-time images, audio, video, and text.
• Bulletproof Systems: Developing secure, observable webhook systems with robust billing, metering, and real-time payment pipelines.

What You'll Bring

Phronetic seeks an experienced engineer comfortable with complex systems and ambiguity.

Core Experience:

• Typically 2+ years of experience in backend engineering roles.
• Expertise in Python, especially with async frameworks like FastAPI.
• Strong command of Docker and cloud deployment (AWS, Cloud Run, or similar).
• Proven experience designing and building microservice or agent-basedarchitectures.

Specialized Experience (Ideal):

• Real-Time Systems: Experience with real time media transmission like WebRTC, WebSockets and ways to process them.
• Scalable Systems: Experience in building scalable, fault-tolerant systems with a strong understanding of observability, monitoring, and alerting best practices.
• Reliable Webhooks: Knowledge of scalable webhook infrastructure with retry logic, backoffs, and security.
• Data Processing: Experience with multimodal data (e.g., OCR, audio transcription, video chunking with FFmpeg/OpenCV).
• Payments & Metering: Familiarity with usage-based billing systems or token-based ledgers.
• Bonus Skills: Knowledge of Rust and Android development is a plus.

Your Impact

The systems designed by this role will form the foundation for:

• Thousands of AI agents for major partners across chat, video, and APIs.
• A new creator economy enabling developers to earn revenue through agents.
• The overall speed, security, and scalability of the Phronetic platform.
