Senior Member Technical Staff - Full Stack Developer ( Java+React) at TheNielsenCompany

We are seeking an experienced Lead Developer to lead technical delivery for a team: hands-on coding, architecture alignment, and raising the bar on quality and operations. You will design and ship backend capabilities, partner on requirements and trade-offs, and help the team deliver reliably in production.   Responsibilities • Design, implement, and review features and APIs (services, integrations, data access). • Own reliability for services you touch: correctness, performance, observability, and safe releases. • Work with the team on architecture for new capabilities and on improving existing systems (database schema, caching, deployment, operational runbooks). • Partner with product and other engineering teams on requirements, estimates, and technical trade-offs. • Review code, clarify design, and mentor engineers informally; contribute to a culture of quality and learning. • Identify and drive process improvements: clearer contracts, better tests, CI/CD hygiene, and reduced operational toil. • Create and maintain technical documentation where it helps onboarding and operations. Requirements • 8+ years of professional experience shipping production backend services in Java (e.g. Spring Boot) or an equivalent JVM stack; comfortable with REST APIs, validation, auth integration (e.g. OAuth2 / JWT), and common Spring patterns. • Data stores — solid PostgreSQL: schema design, migrations (e.g. Flyway or similar), indexing, transactions, and debugging slow queries. • Caching — hands-on use of Redis or Valkey (or similar): cache keys, TTLs, invalidation, and failure modes when cache is down or stale. • Build and quality — Gradle or Maven, unit/integration tests, constructive code review habits, and CI-friendly workflows. • Containers and cloud — Docker; deploying or operating services on AWS (or similar): configs, secrets, logs, metrics. • Observability — metrics, logs, and tracing sufficient to find regressions and latency issues in production. • API and integration design — clear contracts, versioning or backward-compatibility discipline, and safe handling of errors and idempotency where it matters. • Education — Bachelor’s degree in Computer Science, Engineering, or related field (or equivalent practical experience). • Version control — strong experience with Git and collaborative branching/review practices.
