Senior Technical Architect

State Street•Quincy, MA

About The Position

As a hands-on Senior Technical Architect, you will lead end-to-end architecture, design, and implementation of mission-critical systems. You will define macro- and micro-level architecture and work with engineering teams to modernize a VC++ platform into a React/Java-based, event-driven, high-throughput, low-latency microservices platform aligned with cloud-native principles. The role combines architecture and hands-on engineering. You will define and evolve the architecture of a distributed, cloud-native Investment Accounting platform, including modular microservices, event-driven workflows, data and integration patterns, and unified models across IBOR/ABOR domains. You will lead legacy modernization through decomposition strategies, migration patterns, and phased roadmaps, while guiding teams in translating low-level C++ constructs into scalable Java service patterns. The role also encompasses designing for transaction throughput, near-real-time accounting workflows, performance, scalability, and capacity; establishing cache-driven approaches; and implementing cloud-native engineering practices. Cross-cutting responsibilities include observability, resiliency, security, compliance, and adherence to API-first and contract-first design principles.

Requirements

Extensive experience in software architecture and distributed systems design.
Strong programming background in VC++ and Java, with proven system modernization experience.
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.

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.
Familiarity with unified data models and ledger-based architectures.
Experience working in regulatory and audit-heavy environments.

Responsibilities

Define and evolve the architecture of a distributed, cloud-native Investment Accounting platform aligned with scalability, resiliency, and availability principles.
Design modular microservices 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, such as stateless services and asynchronous processing.
Architect high-throughput transaction processing and near-real-time accounting workflows.
Define distributed caching, in-memory processing, and read/write optimization strategies.
Establish performance benchmarks, scalability patterns, and capacity-planning principles.
Design and implement cloud-native capabilities including containerization, orchestration, and DevSecOps.
Establish observability capabilities, including logging, metrics, and tracing.
Establish resiliency patterns such as retries, circuit breakers, and idempotency, as well as security and compliance controls.
Ensure API-first and contract-first design principles are followed.
Work hands-on with engineering teams to design and implement the platform.
