Edge Cloud Voice AI Architect & Technical Lead

Luxoft Germany; United States; Remote; USD 150.000 - 210.000; Vollzeit

Zusammenfassung

Luxoft Germany seeks a Technical Lead and Location Lead for the engineering team to own the architecture of hybrid cloud/edge voice assistant systems. You will drive end-to-end prototype pipelines (ASR → LLM → TTS), evaluate base components, and shape RAG architectures for automotive use cases while ensuring safety, security and interoperability across SOA and microservices.

You will lead an offshore team and coordinate with onshore architects.

Qualifikationen

• Edge/on-device AI optimisation (quantisation, pruning, distillation) for constrained hardware.
• Expert Python
• Hands-on with LLM frameworks in production: LangChain, LangGraph or equivalent.
• 3+ years as architect/technical lead with end-to-end system ownership.
• Track record of taking AI/ML/LLM systems from prototype to production.
• Practical experience building RAG systems: embedding models, vector stores, retrieval evaluation.
• Azure OpenAI Service or OpenAI API in practice, plus Azure cloud (AKS/Container Apps).
• Integration with at least one ASR or TTS engine (Whisper, Azure Speech, Cerence).
• Experience leading a distributed engineering team (5–10 engineers) in Scrum/Kanban.
• English C1, willingness to travel to Germany for workshops.

Aufgaben

• Own system architecture for hybrid (cloud/edge) voice assistant systems—define edge/cloud allocation and boundaries.
• Design and oversee end-to-end prototype pipelines (ASR → LLM → TTS) and test in lab and driving environments.
• Drive evaluation/benchmarking of base components (on-device ASR, TTS, LLM options) for latency, quality and energy.
• Define RAG architectures with embeddings and small vector stores for automotive use cases.
• Architect embedded/edge AI optimisation: quantisation, pruning, distillation for ARM/DSP/NPU with memory/energy focus.
• Shape the research agenda for on-device learning, multimodal interaction, privacy-preserving personalisation.
• Embed safety, security, privacy mechanisms and architecture interoperability (SOA, microservices).
• Lead offshore team as Location Lead: direction for AI/ML & AI Ops, code/design reviews, sprint planning.
• Coordinate with onshore architects and client teams; represent location in architecture boards and ceremonies.
