We are developing a real-time voice AI platform that combines speech recognition, LLM-driven reasoning, and natural-sounding text-to-speech capabilities. This is production-grade software designed to run continuously, scale under heavy load, and deliver human-like conversations with minimal latency.

If you are a seasoned Python engineer who thrives on building resilient systems and solving tough concurrency challenges, this is the role for you.

What You’ll Do/Essential Job Functions

  • Architect and build the conversation orchestration service: ASR → LLM inference → TTS streaming in real time
  • Write robust, asynchronous Python code designed to handle high concurrency without deadlocks, race conditions, or memory leaks
  • Design and maintain clean, well-structured APIs for future scalability and ease of debugging
  • Manage interaction data using SQLAlchemy (or equivalent) with efficient schema design and safe migrations
  • Implement observability: structured logging, metrics, and tracing across the system for instant issue diagnosis
  • Partner with ML and Product teams to rapidly iterate on conversation flow and user experience
  • Enforce a strong testing culture: automated unit tests, E2E flows, and load testing
  • Build resilient systems capable of handling real-world edge cases like noisy audio, unreliable APIs, and flaky networks
  • Continuously profile, optimize, and reduce latency and response times

Requirements

What We Expect You To Know/Requirement

  • Deep Python expertise: 5+ years in Python, production systems experience required, context managers, generators, event loops, GIL, and effective use of asyncio
  • Database fundamentals: data modeling, efficient queries, ORM best practices
  • Networking & I/O: streaming, backpressure, and resilient design for unreliable networks
  • Testing discipline: delivering production-ready, validated code
  • Observability mindset: metrics, logs, and traces are integral to your coding process
  • Production readiness: You’ve built and supported systems running live at scale.

What You’re Like

  • Curious: You don’t just fix bugs — you find root causes
  • Calm under pressure: You can diagnose incidents, resolve them quickly, and prevent recurrences
  • Pragmatic: You solve problems without over-engineering
  • Collaborative: You write code for your teammates and your future self
  • Quality-driven: You refuse to compromise on correctness and reliability
  • Data-informed: You make decisions based on real latency metrics, throughput, and error rates

What To Expect

This is not a feature-factory role. You will be responsible for building a real-time system that stays online, hits latency targets, and performs reliably under pressure.

Team Culture

  • Direct, collaborative, and low on politics
  • High ownership: see your work running in production, serving real users
  • Obsessed with clarity, correctness, and reliability
  • Fast-moving: minimal ceremony, maximum impact
  • Pragmatic planning: no endless poker sessions — scope, assign, design, deploy.

Your Daily Work

  • Ensure performance, reliability, and observability in everything you build
  • Collaborate closely with ML and product teams on speech recognition, TTS voices, and LLM behavior.
  • Monitor, debug, and improve the system as it runs in production.

Working Terms: The candidate must be flexible and work during US hours at least until 6 PM ET, which is essential for this role & must have their own system/work setup for remote work.
