• Fluency and specialization with at least one modern language such as Java, C#, or Go.
• Microservices / SOA, REST and gRPC (or comparable APIs), solid SQL and relational design at scale.
• Cloud (AWS/Azure/GCP), CI/CD, containers, IaC, and production DevOps/observability practices.
• Proven architecture and design for distributed, data‑heavy systems; strong production troubleshooting.
• Excellent communication with technical and non‑technical partners; Agile delivery experience.
• Expertise in complex problem‑solving autonomy, including troubleshooting critical production issues and devising creative, scalable technical solutions under pressure.

Experience

• 10+ years software development with staff/principal‑level impact.
• 8+ years leading architecture and large initiatives with cross‑functional technical leadership.
• 6+ years cloud‑native / distributed systems in production.
• 5+ years high‑volume data, reconciliation, or financial/payments/ledger‑adjacent systems.
• 4+ years major cloud platform.

Preferred

• Financial services / insurance; ERP/GL familiarity.
• Kafka / Snowflake / Airflow; Python/PySpark/Snowpark a plus.

Education

Bachelor’s or Master’s in CS, Engineering, or related field—or equivalent experience.

Location

Hybrid: Bethesda, MD or Dallas, TX.
