Responsibilities
- Design and build the real-time voice runtime for live conversations.
- Build and optimize streaming ASR, TTS, VAD, endpointing, turn-taking, and barge-in.
- Build adaptive voice pipelines for high-noise frontline environments (60-112 dB), hospitals, factory floors, warehouses, including server-side noise cancellation, echo suppression, and dynamic ASR/TTS optimization for PSTN and mobile phone audio quality.
- Architect multi-provider speech routing across a broad multilingual matrix, including code-switching (e.g., Spanglish, Hinglish), where no single ASR or TTS provider covers all languages, and language detection, provider selection, and fallback chains must operate in real time mid-call.
- Develop Voice Agents that support multi-turn, multi-intent conversations, context switching, clarification, and recovery.
- Integrate Voice Agents with workflows, APIs, CRM, ITSM, knowledge bases, and enterprise systems.
- Build secure identity verification, consent, privacy, audit, and compliance controls.
- Implement warm transfer, callback, queue routing, and seamless human handoff with full conversation context.
- Optimize multilingual voice quality across accents, noisy environments, latency, and naturalness.
- Build evaluation frameworks for WER, intent accuracy, response latency, containment, resolution, escalation, and CSAT.
- Establish production observability across the full call path: ASR → LLM → tools → TTS.
- Evaluate and integrate leading speech, telephony, and AI technologies.
- Define architecture, engineering standards, and production readiness for the Voice AI platform.
- Mentor engineers and lead critical technical design reviews.
What success looks like
- Voice Agents feel natural and responsive in real-time conversations.
- Users can interrupt naturally and change context without breaking the conversation.
- The system works reliably across languages, accents, and noisy environments.
- Voice Agents securely execute enterprise workflows and grounded knowledge retrieval.
- Complex cases escalate to humans with full context.
- The platform meets measurable targets for latency, accuracy, reliability, containment, resolution, and customer satisfaction.
Engineering principle
Voice is not chat with audio. Voice is a real-time interaction model with different requirements for latency, interruption, identity, compliance, failure handling, and human handoff.
Your Voice, Unfiltered
We value the real you. To ensure a fair and authentic experience for everyone, we ask that you do not use AI tools (such as real-time answer generators, transcription apps, or note-taking bots) during your interview
Our process is designed to hear your unique story, thought process, and lived experience in real-time. Use of unauthorized AI tools may result in disqualification, as we want to ensure every candidate is evaluated on their own individual merits. We’re excited to meet the person behind the resume!
If you need assistive technology or AI tools for accessibility (e.g., live captioning), please notify your recruiter in advance. We are committed to providing an inclusive interview experience.
Simpplr’s Hub-Hybrid-Remote Model
At Simpplr we believe that when work is good, life is better and that belief guides all we do. Including how we approach our flexible work model. Simpplr operates with a Hub-Hybrid-Remote model. This model is role-based with exceptions and provides employees with the flexibility that many have told us they want.
- Hub – 100% work from Simpplr office. Role requires Simpplifier to be in the office full-time.
- Hybrid – Hybrid work from home and office. Role dictates the ability to work from home, plus benefit from in-person collaboration on a regular basis.
- Remote – 100% remote. Role can be done anywhere within your country of hire, as long as the requirements of the role are met.
