We are on the lookout for a Principal AI/ML Engineer!

As a Principal AI/ML Engineer at Symphony, you’ll lead AI initiatives for global enterprise clients—shaping solutions, building PoCs, and architecting production‑ready ML systems across domains from creative audio/video to complex business workflows. This is a hands‑on technical leadership role where you define strategy, design end‑to‑end architectures, build core components, and set the technical standards for each engagement.

Responsibilities

  • Translate business challenges into AI/ML solutions; lead discovery workshops.
  • Build and present PoCs to validate feasibility and value.
  • Contribute technical input to proposals, scoping, and estimations.
  • Develop models across NLP, CV, audio, and generative AI.
  • Lead fine‑tuning and PEFT methods (LoRA, QLoRA, instruction tuning).
  • Assess architectural trade‑offs: fine‑tuning vs. prompting vs. off‑the‑shelf.
