• Deep expertise in application modernization, re-architecting legacy or mainframe-class systems into Java, Go, or .NET on modern cloud platforms.
• Strong background in data architecture on GCP including BigQuery and data pipeline design.
• Consulting or professional services background with project-based, client-facing delivery experience.
• Experience with AI engineering practices such as harness engineering or spec-driven design.
• Strong requirements gathering skills.
• Experience with test-driven design.
• Advanced proficiency in English.

Nice to have:

• Mainframe or COBOL domain familiarity.
• Experience with DORA metrics.
• QA discipline and practices.
