Role Description This role will reside within the Advanced Technology Center (ATC) Software Delivery team. The Senior Software Engineer is a highly skilled technical contributor responsible for designing and building full-stack software applications, AI-powered solutions, and software-centric lab environments surfaced on wwt.com, as well as contributing to paid proof of concept (PoC) engagements with customers. The ideal candidate brings deep expertise in traditional full-stack web development alongside hands-on experience with the modern AI application stack—including LLM APIs, vector databases, retrieval-augmented generation (RAG) pipelines, agentic frameworks, and AI application orchestration tools. This engineer is comfortable and enthusiastic about leveraging AI-based coding assistants as a core part of their daily development workflow to maximize productivity and code quality. The Senior Software Engineer also serves as a technical anchor on the team, contributing to code review standards, mentoring peers, and delivering software artifacts that showcase WWT’s innovation capabilities to customers and partners. Qualifications - 5+ years of professional software development experience with demonstrated depth in full-stack application development, plus at least 1-2 years of hands-on experience building AI-powered applications. - Required: Bachelor’s degree in Computer Science, Software Engineering, Information Technology, or related field, or equivalent combination of experience and education. - 3+ years of experience with one or more of the following: React or a comparable front-end framework, Node.js or Python back-end development, REST/GraphQL API design, cloud-native deployment (AWS, Azure, or GCP), Docker/Kubernetes, source control (git) and CI/CD pipelines. - Hands-on experience with LLM APIs (OpenAI, Anthropic, Azure OpenAI, etc.), vector databases (Pinecone, Weaviate, pgvector, Chroma, etc.), and agentic AI frameworks (LangChain, LlamaIndex, AutoGen, or similar) is required. - Expert proficiency in full-stack web development across the complete application stack—front-end (React, Next.js, Vue, or equivalent), back-end (Node.js, Python, Go, or equivalent), REST/GraphQL APIs, relational and NoSQL databases—with a commitment to clean, maintainable, production-quality code. - Hands-on experience designing and building AI-powered applications using the modern AI stack: LLM API integration, retrieval-augmented generation (RAG), vector databases, prompt engineering, AI agents, and AI application orchestration frameworks (LangChain, LlamaIndex, AutoGen, or similar). - Demonstrated proficiency using AI-based coding assistants (GitHub Copilot, Cursor, Claude Code, or similar) as a core part of daily development workflow; actively advocates for and models AI-augmented engineering practices that improve productivity and quality. - Strong experience with cloud-native application development and deployment (AWS, Azure, or GCP), containerization (Docker, Kubernetes), and modern DevOps/CI-CD practices including automated testing, code review, and deployment pipelines. - Ability to lead code reviews, mentor junior engineers, and set and uphold team-wide software engineering standards; technical leadership skills sufficient to serve as a senior technical contributor without formal management responsibilities. - Comfortable using Agile practices and Kanban boards as the primary method for managing and organizing work. - Excellent written and verbal communication skills; ability to explain complex technical solutions clearly to both technical and non-technical audiences and produce thorough technical documentation. - Up to 5% domestic travel required. Requirements - Design, architect, and build full-stack web applications and APIs using modern frameworks and languages (e.g., React, Next.js, Node.js, Python, TypeScript, Go) following production-quality engineering standards. - Develop and integrate AI application components including LLM-based features, retrieval-augmented generation (RAG) pipelines, vector databases, agentic workflows, and AI APIs (OpenAI, Anthropic, Azure OpenAI, Google Gemini, etc.) into full-stack applications and ATC lab environments. - Build and maintain software-centric lab environments on wwt.com and develop software prototypes that demonstrate emerging technology capabilities and showcase the art of the possible to WWT customers and partners. - Support paid proof of concept (PoC) engagements by architecting and delivering custom software solutions tailored to specific customer business challenges, working closely with the Team Lead and ATC architects to scope and execute against commitments. - Leverage AI-based coding assistants (e.g., GitHub Copilot, Cursor, Claude Code, or similar tools) as a standard and active part of the development workflow to accelerate delivery, improve code quality, and model AI-augmented engineering practices for the team. - Lead and contribute to code reviews; establish and uphold software engineering best practices for the team including coding standards, testing, documentation, and version control; mentor Software Developers and Delivery Engineers to elevate team-wide technical quality. - Collaborate with the Software Delivery Team Lead, ATC architects, and practice leads to align on technical approach, delivery priorities, and how software solutions map to WWT’s broader customer and go-to-market strategy. - Stay current on full-stack development trends, AI application tooling, cloud-native platforms, and emerging software engineering practices; actively share knowledge and emerging insights with the broader Software Delivery team.
