Solution Architect – AI Voice Backend
Summary
Solution Architect owning the end-to-end technical vision for the AIME (AI Model Engine) backend powering Audi's in-vehicle AI voice assistant. The role designs cloud-native, LLM/RAG-based architectures on Azure (AKS, Azure OpenAI, Cosmos DB), mentors engineers, reviews deliverables, and requires regular presence in Ingolstadt while based in Sofia.
Project description
Our client is advancing its in-vehicle voice assistant into an intelligent, AI-powered companion. Since 2024, large-language-model capabilities (Azure OpenAI / ChatGPT) have been integrated into vehicles using the MIB3 infotainment system, with new E³-architecture models featuring enhanced voice functions from the factory. The AIME (AI Model Engine) backend program supports this development over multiple years, encompassing natural-language dialogue, empathic communication, and a comprehensive cloud-edge data pipeline. DXC Luxoft serves as the end-to-end delivery partner, collaborating as a joint product team with the client's engineers on the Azure platform (AKS, Azure OpenAI, Managed Identity, Azure Monitor, Azure DevOps).
Responsibilities
- We are looking for a Solution Architect to own the technical vision across all three AIME work packages. You will translate Audi's product roadmap into concrete cloud-native, AI-first architectures and act as the primary technical authority in the joint product team. The role spans both high-level design and hands-on review, with regular presence in Ingolstadt.
- Define and maintain the end-to-end system architecture across the LLM/RAG pipeline, voice I/O layer, Azure cloud backend, and in-vehicle edge components.
- Own architecture decision records (ADRs) and ensure alignment between Audi engineers and the DXC Luxoft delivery team.
- Lead solution design for Azure services: AKS, Azure OpenAI, Managed Identity, Azure Monitor, and Cosmos DB.
- Guide AI/ML engineers on LLM integration patterns (RAG, prompt engineering, ASR/TTS orchestration) and ensure production-readiness.
- Conduct technical reviews of pull requests, infrastructure-as-code changes, and sprint deliverables.
- Represent DXC Luxoft in Audi Architecture Board (AP-A) sessions; prepare architecture artefacts and briefing materials.
- Identify and mitigate cross-cutting risks: security, scalability, compliance (ASPICE, ISO 21434).
- Mentor senior engineers and provide cross-WP technical coordination.
SKILLS
Must have
- 5+ years as a Solution or Enterprise Architect for cloud-native, distributed systems.
- Deep hands-on experience with Microsoft Azure: AKS, Azure OpenAI Service, Managed Identity, Azure Monitor / Application Insights, Azure DevOps.
- Proven track record designing AI/LLM-based products in production (RAG pipelines, agentic systems, or voice AI).
- Infrastructure-as-Code (Terraform or Bicep) and CI/CD pipeline design.
- Ability to lead technical discussions with customer architects and senior stakeholders.
- English C1; ability to work effectively in a joint-team model.
Nice to have
• Automotive domain experience (VW Group, CARIAD, MIB3, E³ architecture). • Knowledge of ASPICE L2 process requirements and ISO 21434 cybersecurity obligations. • Experience with edge-cloud hybrid architectures (in-vehicle components connected to cloud backends). • German language skills (B2 or above).
