Mumbai, India ThriveLab Full time

Location:

Mumbai (on-site)

Type:

Full-time

Why this role exists

We're moving from working prototypes to production-grade scale (hundreds → thousands of concurrent calls, sub-300ms turn latency, 99.9%+ uptime, auditable logs). We need an owner who can architect, implement, and scale the platform end-to-end.

What you'll do

  • Design and build the real-time voice pipeline: telephony ASR LLM orchestration TTS with streaming I/O.
  • Own core services: session manager, dialog state, policy/compliance guardrails, analytics/observability.
  • Stand up cloud infra from scratch (VPCs, CI/CD, containers/orchestration, secrets, monitoring, cost controls).
  • Integrate with client systems and third-party APIs (KYC, CRM, LOS, collections, payments) with robust retry/idempotency.
  • Optimize for latency, quality, and cost (model selection, caching, batching, fallback paths).
  • Build internal tooling: conversation replayers, red-team/test harnesses, feature flags, experiment pipelines.
  • Productionize safety/compliance: consent flows, PII handling, encryption, role-based access, audit trails.
  • Measure what matters: concurrency, ASR/TTS/LLM latencies, call success, CSAT proxies, error budgets.

What you'll bring

  • Demonstrated AI builds (personal repos or shipped features at work). Could be voice, NLP, CV-show us real artifacts.
  • Strong systems sense: event-driven services, queues/streams, caching, resiliency patterns, backpressure.
  • Comfortable with integrations: REST/gRPC/webhooks, auth, schema mapping, sandbox→prod hardening.
  • High agency and ownership: you default to unblocking yourself, writing docs, and making trade-offs explicit.
  • Bonus: telephony (Exotel/Twilio), real-time media (WebRTC, gRPC streaming), ASR/TTS (Whisper/Deepgram/Azure/ElevenLabs), vector DB/RAG, Kafka/Redis, Postgres.

Eligibility

  • Software developer (seniority flexible; quality of experience > years).
  • Open to working from our Mumbai office.
  • Full-time only.
  • Prior exposure to finance, gaming, or AI sectors is preferred
