You are responsible for carrying out critical technology solutions across multiple technical areas within various business functions in support of the firm's business objectives.

Job responsibilities

• Leads end-to-end delivery of full stack solutions using React, Java Spring Boot, GraphQL/REST, and AWS-managed services, from design through production support.
• Drives architecture and design reviews, defining service boundaries, API contracts, data models, and integration patterns.
• Develops secure, high-quality, production-grade code; conducts thorough code reviews; sets and enforces engineering standards.
• Builds and maintains highly available and scalable services with strong operational excellence: reliability, performance, cost awareness, and maintainability.
• Implements and governs authentication/authorization using OIDC/OAuth2, token validation, scopes/claims, and service-to-service security patterns.
• Establishes robust observability practices (structured logging, metrics, tracing), incident response readiness (runbooks).
• Evaluates vendor and internal solutions (including architectural fit, security posture, scalability, and operability) and guides adoption decisions.
• Partners with Product and UX to deliver outcomes; translates requirements into technical plans and milestones; proactively manages trade-offs.

• Leverages enterprise-authorized AI coding assist tools within the work environment to improve code quality, delivery speed, and productivity across complex deliverables (e.g., code generation/refactoring, unit test creation, documentation), while validating outputs through peer review, automated testing, and secure coding standards; contributes learnings and reusable patterns to improve broader team effectiveness.

• Applies knowledge of tools within the Software Development Life Cycle toolchain, including enterprise-authorized AI-assisted development and automation capabilities, to improve the value realized by automation.

  Required qualifications, capabilities, and skills

• • Minimum 4+ years of full-stack engineering experience delivering and operating production systems, with senior/lead exposure (technical leadership, design ownership).
  • Strong React expertise (modern patterns, TypeScript, state management, component design systems, performance optimization, responsive UI).
  • Java Spring Boot expertise (API development, dependency injection, validation, error handling, performance tuning).
  • GraphQL proficiency (schema design, resolvers, federation/composition, query performance, caching, governance/versioning).
  • REST proficiency (OpenAPI contract design, pagination/filtering, idempotency, backward compatibility, consumer-driven evolution).
  • OIDC/OAuth2 implementation (JWTs, token flows, scopes/claims, secure sessions, least-privilege access control).
  • Hands-on AWS experience (cloud-native design/deployment, IAM, networking basics, logs/metrics/alarms).
  • Data and event-driven expertise: Aurora PostgreSQL (advanced SQL, indexing, optimization, migrations, transactions), Neptune (graph modeling, Gremlin, performance), and Kafka/MSK (topics, partitions, consumer groups, schema evolution, ordering, idempotency, retries/DLQs, monitoring).
  • CI/CD, quality, and AI-assisted engineering (Git best practices, automated testing, quality gates, release practices; MUST: proficiency with Claude Code/GitHub Copilot ensuring correctness, security, and maintainability).

  • Hands-on experience using enterprise-authorized AI-assisted software development tools within the work environment (e.g., for coding, test creation, troubleshooting, or documentation) with demonstrated ability to critically evaluate, validate, and refine AI-generated outputs for correctness, performance, and security.

  • Understanding of responsible AI use in engineering workflows, including data sensitivity considerations, secure handling of inputs/outputs, and adherence to resiliency and security expectations; ability to guide peers on safe and effective usage within team practices.

  Preferred qualifications, capabilities, and skills

  • Infrastructure as Code (Terraform/CloudFormation/CDK) and deployment automation patterns.
  • Containerization and orchestration experience (Docker, ECS/EKS) depending on platform direction.
  • Advanced security practices: threat modeling, OWASP Top 10 mitigation, secrets management, dependency hygiene.
  • Experience defining platform standards: API governance, event contracts, service templates, and reliability SLOs/SLIs.
  • Prior experience integrating with Oracle HCM.
