At the III level, you own technical delivery end to end, from design through production, and lead technical efforts within your team. You'll make complex decisions on system design and cross-component integration, balancing delivery speed, scalability, and long-term maintainability. You'll also build the internal agentic workflows and MCP integrations that set the team's productivity ceiling, and mentor the engineers coming up behind you.

What you'll be doing:

• Designing, developing, and delivering complex features and services across a full-stack travel platform
• Using Claude Code, Cursor, and GitHub Copilot in daily workflows to accelerate delivery and improve code quality
• Reviewing and validating AI-generated code for correctness, security, performance, and maintainability, and helping set the team's quality bar
• Building and improving internal agentic workflows that automate repetitive engineering tasks like testing, documentation, and code review triage
• Building and configuring Model Context Protocol (MCP) integrations that connect AI agents to internal tools, data sources, and platform services
• Refactoring and modernizing services that have outlasted their original implementations using cloud-native design patterns
• Contributing to architectural decisions across an increasingly distributed architecture
• Advocating for quality, durability, and technical debt reduction with Product Owners, Engineering Managers, and Designers
• Safeguarding the privacy and security of member data in partnership with Risk and Security teams
• Establishing and meeting backend and system SLOs as the platform scales
• Mentoring junior engineers on development practices, code quality, and productive use of AI-assisted tools

What we're looking for:

• 5-8 years of full-stack development experience building web applications and services
• 2+ years of hands-on experience using AI coding agents in professional development workflows
• Strong proficiency in two or more of TypeScript/JavaScript, Python, or C#/.NET
• Deep experience with modern frontend frameworks: React, Next.js, Vue, or Angular
• Experience architecting and deploying applications on AWS, Azure, or GCP
• Strong foundation in RESTful API design and microservices architecture
• Demonstrated ability to use AI coding agents to accelerate delivery and automate engineering workflows
• Working knowledge of the Model Context Protocol (MCP) and hands-on experience configuring MCP servers
• Experience with prompt engineering for code generation, debugging, testing, and documentation
• Experience with real-time streaming or distributed messaging platforms like Redis, Kafka, or RabbitMQ
• Hands-on experience with Docker, CI/CD pipelines, and infrastructure-as-code
• Agile software delivery experience
• Experience mentoring engineers and leading technical design discussions
• Bachelor's in Computer Science, Computer Engineering, or equivalent experience
• Bonus points for working knowledge of Azure AI Foundry, RAG, LangChain, or graph-based data technologies (GraphRAG, GraphDB)
