MTS On Device AI ML (MTS‑EDGE) Engineer

Member of Technical Staff (MTS) — On‑Device ML (MTS‑EDGE) — Kharagpur/Pune/Bombay (On-site Lab=Garage Work from Office Only)

Put intelligence where it earns trust: on the device, by default.

Why this role exists

Kai and Nav are only as trusted as their privacy and responsiveness. On‑device inference gives us both. Your work delivers real‑time speech, local understanding, and smooth synthesis with battery and memory budgets that respect the user—and the product.

What you’ll do

• Quantize, distill, and compile models (VAD/ASR/NLU/TTS/Small‑LLMs) for

  CoreML/Metal

  with streaming pipelines.
• Build offline fallbacks and clever

  on‑device first, cloud‑when‑necessary

  routing with clear consent gates.
• Instrument latency, accuracy, power, memory, and binary size; land targets and keep them there.
• Partner with iOS to ship low‑friction voice UX (barge‑in, barge‑out, interruption repair).
• Collaborate with Orchestration to design tool contracts that exploit edge capabilities (wake‑words, local context, cache).
• Maintain a reproducible toolchain (PyTorch → ONNX → CoreML) with deterministic builds and golden benchmarks.

30 / 60 / 90 outcomes

• 30 days

  : Baseline

  ASR+TTS

  pipeline running locally with streaming; p95 end‑to‑end voice turnaround <800 ms on a recent iPhone; battery/thermal tracing in place.

• 60 days

  : Add wake‑word, VAD, and small‑footprint NLU; offline short‑task mode (notes, reminders, follow‑ups); accuracy/latency dashboards shipped.

• 90 days

  : >85% task‑success on the on‑device golden set; stable

  MOS

  for TTS; memory <300 MB at p95; <3% battery per 10‑minute assisted session.

Signals we’re looking for

• You’ve shipped

  CoreML/Metal

  inference with real‑time audio and can show profiling traces.
• You’ve done

  quantization

  (INT8/INT4), distillation, or sparsity and can explain the trade‑offs.
• Comfort across Swift/C++ bridging, AVAudioEngine, and low‑latency I/O.
• Taste for graceful degradation and offline safety.

The stack you’ll touch

CoreML, Metal, Accelerate, AVAudioEngine, Swift/C++, PyTorch, ONNX, Python toolchains, Instruments, power/thermal profilers.

How we work

Campus pilots, weekly ships, privacy by architecture, ruthless measurement, written decisions, small senior team.
