- 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):
- 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.
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.
