About the role
- We work in small, highly skilled teams, prioritize clarity over complexity, and continuously evolve through curiosity, data, and craftsmanship.
- With hubs in New York City, Mountain View, Latin America, and India.
- You will work closely with Speech Scientists, ML Researchers, and Infrastructure Engineers to bridge cutting-edge speech technology with hardened production systems.
Responsibilities
- Tune and optimize ASR and TTS models for real-world call center environments, improving transcription accuracy, noise robustness, and speaker variability
- Balance latency vs. quality tradeoffs in streaming speech pipelines to maintain real-time responsiveness
- Build multi-threaded, low-latency server frameworks capable of handling thousands of concurrent real-time audio streams
- Design and operate streaming ASR → LLM → TTS pipelines that power live AI-driven customer conversations
- Develop robust media stream handling to ensure reliable audio flow between telephony providers, clients, and ML services
- Define and implement speech quality evaluation frameworks, including WER/CER analysis, latency tracking, and perceptual TTS metrics
- Build tooling and dashboards to monitor production performance and detect regressions in accuracy, latency, or naturalness
- Create load-testing and simulation tools to model high-concurrency, real-world voice traffic
- Partner with Speech Scientists and ML Researchers to productionize new ASR and TTS models
- Collaborate with Product teams to translate conversational quality requirements into measurable system improvements
Requirements
- Strong proficiency in Golang or Python (or willingness to become an expert quickly)
- Experience designing low-latency, high-concurrency systems, ideally involving real-time media or streaming data
- Speech & Audio Expertise
- Practical experience working with ASR and/or TTS systems in applied or production environments
- Familiarity with speech quality metrics such as WER, CER, MOS, latency, and streaming stability
- Experience evaluating model performance and running structured experiments to improve transcription accuracy and speech naturalness
- Comfort working with modern ML tooling and model APIs to fine-tune, adapt, or post-process speech model outputs
- Ability to make pragmatic tradeoffs between model quality, compute cost, and real-time constraints
- Experience with noise reduction, echo cancellation, VAD, diarization, or other speech enhancement technologies
- Familiarity with forced alignment techniques or phoneme/word-level timing models
Compensation
- $215k-$235k
Benefits
- If you're driven by continuous learning, rapid iteration, and the challenge of building in a high-growth startup, this is more than a role-it's a journey.
