We are seeking a Technical Architect to lead the end-to-end architectural design and technical oversight of a major modernization initiative. This role is central to the strategic replatforming effort transitioning from a legacy C/C++ system to a scalable, robust, and cloud-adaptable Java-based architecture.

You will define the Target State Architecture and Blueprint, ensuring alignment with enterprise-wide objectives and technical best practices. As a hands-on and visionary architect, you will collaborate with cross-functional teams across infrastructure, security, development, and operations to shape a secure, high-performance, future-ready platform.

Key Responsibilities

  • Drive the creation of the Target State Architecture and Blueprint, including system interaction models and integration flows.
  • Define and validate architecture diagrams, technical patterns, and component interaction models across tiers.
  • Provide final sign-off and governance over all architectural deliverables and designs.
  • Strategic Implementation Oversight
  • Ensure the accurate translation of architecture into implementation throughout the SDLC and production rollout.
  • Collaborate with project management, development, QA, and DevOps teams to ensure consistency and technical integrity.
  • Lead architecture reviews, risk assessments, and mitigation planning for the modernization program.
  • Cross-functional Technical Collaboration
  • Act as the primary architectural liaison between platform engineering, web services, security, data, and deployment teams.
  • Provide mentorship and technical guidance to engineers and solution designers involved in the migration.
  • Discovery & Migration Planning
  • Participate in the “Technical Discovery & Blueprint Design” phase, defining the platform’s long-term architectural roadmap.
  • Oversee migration strategies during the “Application Migration of Messaging Layer” phase, especially around technologies like Apache Kafka.
  • Required Qualifications

Professional Experience

  • 12+ years in software engineering or architecture roles, with at least 5+ years in enterprise-scale architectural leadership.
  • Direct experience leading legacy-to-modern technology transformations, ideally in financial services or other high-availability sectors.
  • Hands-on architectural experience with Java platforms, C/C++ systems, Oracle 19c, and enterprise messaging systems.

Technical Expertise

  • Deep knowledge of middleware, message brokers (e.g., Kafka, IBM MQ), and enterprise integration patterns.
  • Proven track record in designing scalable, fault-tolerant, and secure microservices-based architectures.
  • Solid understanding of performance tuning, HA/DR configurations, and low-latency system design.
  • Comfortable working with cloud-native and containerized architectures is a plus.
  • Communication & Stakeholder Management
  • Strong communication skills to translate complex technical concepts into business-aligned strategy.
  • Experience engaging with senior stakeholders, architects, and cross-functional technical teams.

Nice to Have

  • Experience with API gateway, security protocols (OAuth2, TLS, etc.), and observability tooling.
  • Exposure to cloud platforms (AWS, GCP, or Azure) and infrastructure-as-code tools (Terraform, Ansible).
  • Familiarity with regulatory requirements and compliance frameworks relevant to financial institutions.
