- Build processing workflows for transcription, speaker separation, anonymisation, enrichment, storage, and retrieval
- Design secure and scalable AWS infrastructure using services such as S3, Lambda, ECS / Fargate, Step Functions, EventBridge, and RDS
- Model and store both structured and semantic conversation data using PostgreSQL and vector search
- Implement observability, alerting, audit logging, and operational safeguards for privacy-sensitive systems
- Work closely with leadership and internal stakeholders to translate business questions into technical solutions
- Help shape the technical roadmap, delivery approach, and engineering standards for this area of the platform
Key Skills:
