• System Reliability: Monitor the reliability and performance of Vantage cloud services; lead resolution of critical incidents and drive systemic improvements to prevent recurrence.
• Technical Innovation: Evaluate emerging technologies – including advances in GenAI, purpose-built Document AI models, and cloud-native tooling – and translate them into concrete improvements for the Vantage platform.
• Required Qualifications:
• 10–13 years of professional software engineering experience with deep expertise in C# and .NET
• Scope of responsibility: Full Product – accountable for technical quality and architectural integrity across the entire Vantage platform

• Experience with compliance-driven engineering in regulated environments (SOC 2, GDPR, FIPS, STIG, or ISO frameworks)
• Desired Qualifications:
• Ownership Mindset: Passion for end-to-end ownership of Document AI features – from OCR and extraction accuracy to LLM-based enrichment and human-in-the-loop validation workflows
• Performance & Optimization: Experience profiling and optimizing high-throughput document processing services for latency, throughput, and cost at scale
• Hands-on familiarity with Azure OpenAI, LLM prompt engineering, or BYOM (Bring Your Own Model) integration patterns
