Full Stack Software Engineer II

Build and operate partner-facing identity verification (IDV) solutions across React micro-frontends and Java/Spring Boot backend services. Own features from technical design through production support while collaborating independently across product, design, data, platform, and vendor teams.

### Key Responsibilities

- Design, build, test, and operate secure, scalable end-to-end features.
- Develop React/TypeScript components and micro-frontend integrations.
- Build Java/Spring Boot APIs, business logic, and IDV/vendor platform integrations.
- Handle authentication, workflow orchestration, retries, failures, and sensitive identity data securely.
- Work with REST/GraphQL APIs, event-driven services, MySQL, caching, and Kafka.
- Verify changes through unit, integration, and end-to-end tests, including standalone and host-MFE testing.
- Use CI/CD and production observability—logs, metrics, traces, and alerts—to deliver and support reliable services.
- Navigate ambiguity, clarify requirements, and independently drive solutions from discovery to production.
- Coordinate dependencies and resolve integration or operational issues across multiple teams.
- Contribute to technical design, code reviews, engineering standards, and mentoring.

### Required Qualifications

- 6+ years of professional software engineering experience.
- Strong Java and Spring Boot/Dropwizard experience, including production APIs and microservices.
- Experience with React, TypeScript, HTML, CSS, and component-based frontend development.
- Experience integrating third-party platforms or vendors; IDV, fraud, payments, or KYC experience is beneficial.
- Knowledge of distributed systems, relational databases, efficient SQL, and automated testing.
- Experience with Git, CI/CD, cloud environments, and production incident handling.
- Strong ownership, communication, and ability to make pragmatic technical trade-offs.
- Experience using modern AI development tools while maintaining engineering quality.

### Nice to Have

- AWS, Kubernetes, Kafka, GraphQL and high-volume service experience.
- Micro-frontend/component-service/Capla architecture and design-system experience.
- Accessibility, performance tuning, experimentation, or e-commerce/travel domain knowledge.
