Duration: / Term: 6+ months

Job Description:

Experience Desired: 8+ Years
 

Job Description:

Full Stack designs, develops, and delivers scalable software solutions that enable scalable, highly available, and secure systems across the enterprise. This role partners closely with architects, product owners, data engineers, and privacy stakeholders to build services and platforms that support regulatory compliance while maintaining performance and scalability. The engineer leads technical design and implementation of UI, microservices, APIs, and event-driven architectures, and contributes to system architecture, automation, and reliability. Success is measured by the quality, scalability, and reliability of delivered software, adherence to privacy and compliance requirements, and the ability to influence technical outcomes across teams. In addition to backend services, this role designs and builds responsive, accessible, and performant user interfaces, delivering end-to-end features across UI, API, and data layers.

What You’ll Do

• Design and build responsive, accessible, and performant user interfaces using React
• Deliver end-to-end features across UI, API, and data layers, ensuring consistency in design, performance, and security
• Develop and maintain automated UI and end-to-end test suites using Playwright or equivalent
• Design, develop, test, and deploy high-quality software solutions using Java and Spring Boot
• Build scalable, high-performing RESTful APIs and microservices aligned with privacy and compliance requirements
• Implement and support event-driven and message-based architectures using Kafka or similar technologies
• Build scalable ETL frameworks using object-oriented Python and Java programming languages
• Collaborate with cross-functional teams, including product, architecture, data, and privacy, to deliver compliant solutions
• Contribute to system and application architecture, including service design, data flows, and integration patterns
• Participate in code reviews, agile ceremonies, and technical design discussions
• Troubleshoot and resolve complex software issues across development and production environments
• Develop and maintain CI/CD pipelines, automation, and deployment workflows
• Write and maintain clear technical documentation, including design documents and system specifications
• Continuously evaluate and adopt modern technologies to improve system performance, reliability, and maintainability
• Daily use of AI productivity tools (Claude, Cursor) is required across the software development lifecycle —including design, API and microservice development, code generation, code review, testing, debugging, deployment, documentation, and production support.
• Design, build, and operate AI agents that automate software engineering tasks such as generating boilerplate code for new microservices, creating unit and API tests, analyzing logs, triaging incidents, and supporting CI/CD pipelines.
• Build and integrate AI-enabled capabilities into backend services and APIs using foundation models, prompt engineering, and retrieval-augmented generation (RAG) patterns.
• Implement audit logging, observability, and human-in-the-loop controls for AI agents and AI-assisted workflows running in Tier-0 production environments.

What You’ll Bring

• Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience
• 6+ years of software engineering experience, building and supporting enterprise-grade applications
• Strong experience working in Agile or Scrum-based development environments
• Demonstrated ability to work independently on complex technical problems while collaborating across teams
• Strong analytical, problem-solving, and communication skills
• Demonstrated experience building production user interfaces with React
• Familiarity with foundation models, prompt engineering, retrieval-augmented generation (RAG), and AI agent development applied to full-stack application development, including enterprise reusable solutions

Must Have Skills

• Strong experience with JavaScript/TypeScript and React for building production user interfaces
• Proficiency with messaging and event-driven systems such as Kafka
• Experience with frontend build tooling, package management, and component-based design
• Experience with end-to-end and UI test automation using Playwright or equivalent
• Proficiency with front-end technologies, including HTML, CSS, JavaScript, and Webpack
• Strong experience with Python object-oriented programming, Java, and Spring Boot
• Experience building scalable REST APIs and microservices
• Experience working with JSON and XML, including schema validation
• Experience with Git, GitLab, and CI/CD automation
• Hands-on experience working on Unix OS and proficient in shell scripting
• Experience developing test automation using tools such as JUnit or Karate
• Proficiency with API testing tools such as Postman
• Experience working with relational databases and writing complex SQL
• Experience with containerization and orchestration tools such as Docker and Kubernetes
• Strong experience using observability and telemetry tools such as Splunk, AppDynamics, or Grafana
• Hands-on experience with AI productivity tools (Claude and Cursor or similar IDE) and working knowledge of foundation models, prompt engineering, retrieval-augmented generation (RAG), and AI agent development.

Nice to Have

• Experience with Snowflake or cloud-based data platforms
• Network Domain experience
• Experience working in cloud-native environments (Azure, AWS, or Google Cloud Platform)
• Experience contributing to system architecture or platform-level design decisions
