About the role

Key responsibilities & impact

Architectural Migration: Lead the technical strategy, design, and execution of extracting deep business logic from existing Oracle PL/SQL stored procedures and re-architecting them into highly modular .NET 8 microservices.
Cloud & DevOps Leadership: Design and oversee the deployment architecture within a cloud environment, primarily leveraging AWS EKS (Elastic Kubernetes Service) and AWS Service Mesh (or equivalent cloud native tools).
Team Technical Leadership: Provide direct mentorship, technical direction, and code/design review guardrails for a team of 5 backend engineers.
Design & Best Practices: Define microservices patterns, database communication strategies, data validation frameworks, and performance-tuning guidelines for the new ecosystem.
Cross-Functional Collaboration: Act as the primary technical point of contact during the migration, bridging the gap between legacy database structures and modern cloud-native architectures.

Requirements

What you’ll need

Total Experience: 10+ years in software engineering with a strong progression into application and system architecture. 5+ years of experience in core architecture.
Backend Expertise: Expert-level proficiency in .NET 8 core frameworks, C#, and building robust Web APIs / microservices.
Database Mastery: Deep hands-on experience with Oracle SQL / PL/SQL. You must be highly proficient at reading, analyzing, and dismantling complex legacy stored procedures.
Cloud Infrastructure: Strong hands-on experience with cloud platforms, specifically AWS. Proven familiarity with AWS EKS and AWS Service Mesh architectures is highly preferred (experience with comparable container orchestration and service mesh tools on Azure/GCP will be considered).
Leadership Capabilities: Prior experience leading or mentoring small-to-medium development teams (4–6 engineers), managing sprint technical goals, and executing code quality frameworks.
A Bachelor’s degree in Computer Science, Computer Engineering, or related or equivalent work experience required.
