Senior Python Engineer (AsyncIO & Concurrency) - Remote

Overview

We are seeking a Staff Systems Engineer with deep expertise in Python’s asyncio framework to architect and implement high-concurrency, low-latency backend systems for real-time voice-driven applications. This role will focus on event-driven design, asynchronous processing pipelines, and performance-critical middleware that interacts with voice AI services and hardware systems. The ideal candidate is fluent in Python concurrency patterns and can architect scalable, fault-tolerant systems that drive next-generation drive-thru automation.

In Short

• Design and implement high-performance asynchronous systems using asyncio, aiohttp, and real-time communication protocols.
• Architect event loops, task scheduling frameworks, and non-blocking I/O for voice streaming pipelines.
• Build async audio routing and processing layers for handling real-time audio streams.
• Ensure tight control over memory usage, CPU-bound blocking, and coroutine orchestration.
• Develop WebSocket and HTTP APIs using asynchronous frameworks (e.g., FastAPI).
• Write async middleware to manage voice interactions, user state, and session lifecycles.
• Profile event loops, optimize coroutine concurrency, and resolve deadlocks, race conditions, and memory leaks.
• Implement watchdog timers, graceful degradation, and recovery for long-running async tasks.
• Develop observability tooling for async-heavy services including tracing, logging, and custom metrics.
• Collaborate with voice engineers, hardware integrators, and AI/ML teams to ensure asynchronous interfaces meet real-time constraints.

Requirements

• Fluent in Python concurrency patterns.
• Experience with asyncio and aiohttp frameworks.
• Strong understanding of event-driven design and asynchronous processing.
• Ability to architect scalable and fault-tolerant systems.
• Experience in developing WebSocket and HTTP APIs.
• Knowledge of performance profiling and debugging techniques.
• Experience with observability tooling for async services.
• Strong collaboration skills with cross-functional teams.
• Mentorship experience in best practices for Python concurrency.

Benefits

• Opportunity to work on cutting-edge voice-driven applications.
• Collaborative and innovative work environment.
• Professional development and mentorship opportunities.
• Competitive salary and benefits package.
• Flexible working hours.
