Job description

As a hands on Senior Technical Architect, you will be responsible for end-to-end architecture, design, and implementation of mission-critical systems. You will define both macro and micro level architecture and implement with engineering teams to modernize a VC++ platform into Reacts JS/Java based event based high throughput, low latency micro services based platform, ensuring alignment with cloud-native principles.

Key Responsibilities

Architecture & Platform Design

• Define and evolve the architecture for a distributed, cloud-native Investment Accounting platform, aligned with enterprise principles (scalability, resiliency, availability).
• Design modular microservices architectures, ensuring clear service boundaries, domain-driven design, and reusability across business capabilities.
• Establish event-driven architecture patterns for real-time processing, enabling decoupled and scalable workflows.
• Define data architecture and integration patterns, including unified data models, event contracts, and consistency strategies across IBOR/ABOR domains.

Modernization Leadership

• Lead the modernization of legacy VC++ systems into Java-based, distributed services
• Define migration patterns, decomposition strategies, and phased transformation roadmaps
• Ensure functional equivalence where required, while enabling architectural evolution beyond legacy constraints
• Guide teams on translating low-level C++ constructs into scalable Java service patterns (stateless services, async processing, etc.)

Performance, Throughput & Scalability

• Define cache-driven design strategies (distributed caching, in-memory processing, read/write optimization)
• Establish performance benchmarks, scalability patterns, and capacity planning principles

Cloud-Native & Engineering

• Design and implement for cloud-native (containerization
  orchestration, DevSecOps).
• Establish cross-cutting capabilities:
• Observability (logging, metrics, tracing) for operational intelligence
• Resiliency patterns (retry, circuit breaker, idempotency)
• Security and compliance controls
• Ensure API-first and contract-first design principles are adhered to.

Required Qualifications

• Extensive experience in software architecture and distributed systems design
• Strong programming background in VC++ and Java, with proven experience in system modernization
• Rich experience with AWS/Azure along with modern CICD platforms and pipeline as code
• Experience building large-scale distributed systems with low latency and high throughput
• Strong understanding of data consistency, transaction processing, and accounting-like systems

Preferred Qualifications

• Experience in Investment Accounting / Financial Services platforms (transactions, valuations, positions, multi-currency processing)
• Familiarity with Observability and operational intelligence frameworks
• Unified data models and ledger-based architectures
• Experience working in regulatory and audit-heavy environments
