About the Role

This role plays a critical part in shaping the technical direction of product domains and system ecosystems across a workstream by defining cross-domain architecture, aligning systems across teams, and ensuring the platform scales reliably with the business. The position requires deep technical expertise, strong architectural judgment, and the ability to influence engineering teams across multiple domains and value lanes.



You’ll collaborate closely with engineering leaders, product managers, and product designers to deliver resilient, secure, and scalable financial systems. This is a high-impact opportunity to improve system cohesion, strengthen engineering practices across teams, and enable durable customer and business outcomes.

A workstream is a product-aligned engineering organization responsible for delivering a cohesive set of customer and business capabilities. Within a workstream, domains are composed of multiple value lanes (teams), each with its own charter and outcomes. Senior Staff Engineers ensure that systems across these domains operate cohesively and evolve in a consistent, scalable way.

This role is focused on driving architectural cohesion and enabling scalable, high-impact solutions across three core areas: customer-facing AI innovation, AI-driven risk and fraud, and AI-enabled operational efficiency.

You will lead the design and alignment of systems that support AI-powered product capabilities, ensuring teams can rapidly prototype and productionize features while maintaining consistency, reliability, and long-term maintainability. This includes guiding how new ideas evolve into production-ready systems across multiple teams. You will also shape the architecture of AI-driven risk and fraud systems, ensuring solutions are scalable, measurable,



and resilient to evolving threats. In parallel, you will drive the adoption of AI-enabled tools and workflows across the organization, improving developer experience, product development processes, and broader business operations through consistent and scalable patterns.

The Senior Staff Software Engineer is responsible for aligning technical direction across domains, defining architectural patterns, and ensuring systems operate cohesively across teams. This role requires deep technical expertise, robust architectural judgment, and the ability to influence engineering decisions without direct authority. You will partner closely with engineering leaders, product managers, and product designers to translate product strategy into cohesive technical systems that deliver measurable customer and business outcomes.

Responsibilities

- Leads the design and evolution of complex systems spanning multiple domains, ensuring scalability, reliability, and long-term maintainability across a workstream.
- Defines and drives architectural patterns, service boundaries, and system interactions that enable multiple teams to build and evolve systems consistently.
- Aligns technical design across teams and domains, ensuring systems interoperate effectively and reduce fragmentation.
- Influences implementation decisions across teams to ensure alignment with architectural standards and long-term platform direction.
- Evaluates trade-offs across performance, reliability, scalability, cost, and development velocity, guiding teams toward sound engineering decisions.
- Establishes and scales testing strategies, validation patterns, and quality standards across domains to ensure co
