About Us

Appnovation is a global, full-service digital partner that combines Strategy, Experience & Design, Engineering and Managed Services. We build digital solutions that deliver real impact today and serve as foundations for future growth. Bold ambition. Practical action. Endless possibilities.

Technology is foundational to all of Appnovation's offerings, from consulting to digital innovation, to digital product and service creation. The technology department is focused on delivering software solutions that enable rich consumer experiences, from mobile and web applications to advanced analytics and machine learning, to content and engagement management service enablement platforms.

Inherent throughout our tech capabilities is deep expertise in the Software Development Life Cycle, a drive for creativity, a passion for the craft, and collaboration with other disciplines - all foundational ingredients in successful digital experiences and client partnerships.

As a Data Architect / Engineer, you will join a highly motivated and experienced team and own both the data structures behind our graph-RAG platform and the pipelines that get content into it - modeling the knowledge and pumping it in at scale. You will define the schema, taxonomy and graph model for our knowledge domains, build resilient ingestion pipelines from enterprise content sources such as SharePoint and the wider Microsoft stack, and keep the knowledge graph accurate as source documents evolve. We are looking for people who can bring a strong, solution-focused mindset and contribute to architectural decisions, best practices and get things done.

Key Responsibilities

• Define the schema, taxonomy, and graph modeling for the knowledge domains.
• Design how documents, versions, and their machine-readable representations are structured, and how facts evolve over time (including temporal replay).
• Build ingestion/ETL pipelines from enterprise content sources (e.g., SharePoint and the wider Microsoft stack), handling multimodal content (presentations, documents, transcripts).
• Keep the knowledge graph in sync as source documents change frequently.
• Advise on whether the current backend approach (Supabase/Postgres) is the right long-term architecture, and validate ingested content quality with QA.
• Establish data quality, lineage, and governance standards across pipelines.
• Build monitoring, alerting, and error-handling for ingestion jobs.
• Document data models, schemas, and pipeline architecture.
• Optimize pipeline cost, throughput, and reliability over time.

• You have solid analytical, problem solving and decision-making skills
