Join a team of passionate thinkers, innovators, and dreamers — and help us connect people and build communities to create economic opportunity for all.

The Role Reporting directly to the VP of Engineering, C2C & Seller Experiences, you will serve as a lead technical visionary for the platforms and architectures that empower millions of C2C and professional sellers globally. As a Distinguished MTS, you are a high-impact technical individual contributor responsible for the end-to-end architectural integrity and technical strategy of the Seller journey.

In this role, you will define how we build, scale, and transform a high-scale legacy environment into a modern, decoupled ecosystem across Web Front-End, Native Mobile (iOS & Android), and Backend architectures (primarily Kotlin and Java, with a strategic migration away from legacy Scala). You are a practitioner-leader who balances high-level strategic design with hands-on execution, ensuring our systems are optimized for flow efficiency and colleague engagement.

Your Responsibilities:

• Outcome-Led Architecture**:** Move beyond "feature factory" thinking. You will define technical strategies based on Outcome Hypotheses, measuring success through Better Value Sooner Safer Happier (BVSSH) metrics—prioritizing quality, unique business outcomes, time-to-learning, continuous compliance, and developer joy.
• Legacy Transformation & Modernization: Lead the architectural evolution of our core commerce systems. You will create and execute the roadmap to transform highly coupled monolithic services into a modern, distributed architecture, ensuring business continuity while radically improving system maintainability and deployment safety.
• Domain-Driven Design (DDD) & Descaling**:Lead the evolution of our domain boundaries. You will apply the pattern of"**Achieve Big through Small"—descaling complex systems into clean, bounded contexts that minimize cognitive load and allow multidisciplinary teams to deliver independently.
• Client-Oriented Decoupling**:** Leverage Federated GraphQL to drive consumer-driven contracts. You will architect the graph to empower Web and Native Mobile teams to iterate rapidly and independently of backend release cycles, ensuring a flexible and performant data layer.
• Optimize for Flow & Learning: Architect for flow efficiency, identifying and alleviating systemic impediments like waits and handoffs. You will enable fast, safe-to-fail experiments across our JVM-based services to maximize the "speed to learning."
• Psychological Safety as a Foundation**:** Cultivate an environment of Psychological Safetywhere intelligent failure is celebrated as learning. You will lead by example, encouraging experimentation and a "blameless" culture where every engineer feels empowered to innovate and challenge the status quo.
• Hands-on Practitioner: You lead by doing. You will write code, build foundational frameworks, and establish the "prior art" (patterns) that help our global engineering teams avoid common anti-patterns during the transformation journey.

Required Qualifications

• Education: Master’s degree in Computer Science, or a Bachelor’s degree with equivalent high-level architectural experience.
• Experience**:** 15–20+ years of relevant, broad engineering experience leading the delivery of services and large-scale distributed systems.
• Proven Track Record**:** Successfully delivering large-scale enterprise-wide solutions, from design to development to testing to production.
• Full-Stack Fluency**:** Deep understanding of Java, Kotlin, and Scala within the JVM ecosystem, alongside modern Web FE (React/Node) and Native Mobile (iOS/Android) architectures.
• Modern Infrastructure**:** Solid understanding of Spring, Docker, and Kubernetes, with a strong advocacy for automated testing, continuous delivery, and software quality across the entire SDLC.
• Architecture Patterns**:** Deep experience with service-based architectures, Domain-Driven Design, and reactive/event-driven systems.
• Transformation Mastery**:** Demonstrated success in modernizing highly coupled, monolithic enterprise systems and implementing Federated GraphQL for client-backend decoupling.
• Leadership & Communication**:** Strong customer focus and excellent relationship-building skills. Ability to frame complex problems clearly and meaningfully for both engineers and executives.
• Mentorship**:** Proven experience mentoring and training a broad engineering community on sophisticated technical issues.
• Mindset**:** A willingness to dive deep into details with an iterative approach to problems and solutions. A commitment to Psychological Safety and the principles of Sooner Safer Happier.
