Who we are: My AI Client is building the foundational platform for the "agentic economy," moving beyond simple chatbots to create an ecosystem for autonomous AI agents and 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. My AI Client 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
- My AI Client seeks an experienced engineer comfortable with complex systems and ambiguity.
Core Experience:
● Typically 3 to 5 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-based architectures.
Specialized Experience (Ideal):

- 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.
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 my client’s AI platform.
Why Join Us?
- Opportunity to solve hard problems with clean, scalable code.
- Small, fast-paced team with high ownership and zero micromanagement.
- Belief in platform engineering as a craft and care for developer experience.
- Conviction that AI agents are the future, and a desire to build their powering platform.
