About The Position

The Senior Technical Architect is a hands-on role responsible for end-to-end architecture, design, and implementation of mission-critical systems. The role defines macro- and micro-level architecture and works directly with engineering teams to modernize a legacy VC++ platform into a React/Java-based, event-driven, high-throughput, low-latency microservices platform aligned with cloud-native principles.

The architect will define and evolve a distributed, cloud-native Investment Accounting platform; lead modernization and phased transformation of legacy systems; and guide engineering teams in developing scalable services. The position also focuses on performance, throughput, resiliency, observability, security, compliance, and API- and contract-first engineering. Hands-on implementation capability is essential.

Requirements

• 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 or Azure, modern CI/CD 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.
• Hands-on experience and ability to implement architecture alongside engineering teams.

Nice To Haves

• Experience with Investment Accounting or Financial Services platforms, including transactions, valuations, positions, and 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.

Responsibilities

• Define and evolve architecture for a distributed, cloud-native Investment Accounting platform aligned with scalability, resiliency, and availability principles.
• Design modular microservices architectures with clear service boundaries, domain-driven design, and reuse across business capabilities.
• Establish event-driven architecture patterns for real-time processing and decoupled workflows.
• Define data architecture and integration patterns, including unified data models, event contracts, and consistency strategies across IBOR/ABOR domains.
• Lead 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 in translating low-level C++ constructs into scalable Java service patterns, including stateless services and asynchronous processing.
• Architect systems for high-throughput transaction processing and near-real-time accounting workflows.
• Define cache-driven design strategies, including distributed caching, in-memory processing, and read/write optimization.
• Establish performance benchmarks, scalability patterns, and capacity-planning principles.
• Design and implement cloud-native solutions, including containerization, orchestration, and DevSecOps.
• Establish observability capabilities for operational intelligence, including logging, metrics, and tracing.
• Establish resiliency patterns such as retries, circuit breakers, and idempotency, as well as security and compliance controls.
• Ensure adherence to API-first and contract-first design principles.
• Work hands-on with engineering teams to implement the architecture.

Benefits

• 401(k) retirement savings plan with company match.
• Insurance coverage including basic life, medical, dental, vision, long-term disability, and optional additional coverages.
• Paid time off including vacation, sick leave, short-term disability, and leave for family care responsibilities.
• Access to an Employee Assistance Program.
• Eligibility for annual performance-based incentive awards, with exceptions for certain sales roles.
• Eligibility for certain tax-advantaged savings plans.
• Inclusive development opportunities, flexible work-life support, paid volunteer days, and employee networks.
