Arrivia powers the travel behind many of the world's membership and loyalty brands. Its private travel marketplace gives members access to deeply discounted cruises, resorts, and hotels, and its platform runs the booking, servicing, and rewards underneath those programs. The engineering teams build and scale that platform across a distributed, cloud-native architecture.

As a Senior Agentic Software Engineer, you architect systems, set technical direction, and drive engineering standards across teams, shipping faster and smarter with AI coding agents as core development tools. You operate with limited oversight and broad organizational scope, with wide latitude to set objectives and approaches for critical technical initiatives. You make the high-impact architectural and strategic calls that shape the platform's technical foundation, weighing innovation, risk, scalability, and business impact. And you shape how the whole organization builds with agents: driving the adoption and standardization of tools like Claude Code, Cursor, and GitHub Copilot, establishing best practices, prompt libraries, and workflows that lift productivity company-wide, designing the org's agentic workflow strategy, and architecting the Model Context Protocol (MCP) server ecosystems that give AI agents secure, structured access to internal tools, data, and platform services. This role is based onsite in Phoenix, AZ, on a fast-paced, highly collaborative team that spans US and international time zones. Expect 8+ years of full-stack and architectural experience and expert-level fluency with coding agents, across TypeScript/JavaScript, Python, or C#/.NET, a front-end framework like React, Next.js, Vue, or Angular, and a cloud platform (AWS, Azure, or GCP).

You fit if you lead by example and bring both depth and influence: you set the quality bar for AI-generated code across teams, you mentor engineers on prompt engineering and agentic workflow design, and you help shape technology investment decisions. You care about the product and the member on the other end, you collaborate across product, design, and engineering, and you revitalize services that have outlasted their original design through refactoring, migration, and cloud-native distributed architecture. A deep understanding of MCP and architecting MCP server ecosystems, advanced prompt engineering with reusable patterns and libraries, RESTful APIs and microservices, streaming platforms like Redis, Kafka, or RabbitMQ, containerization and orchestration with Docker and Kubernetes, and CI/CD rounds out the picture, and experience with Azure AI Foundry, RAG, LangChain, or graph-based data technologies is a plus.

Applying with Provn is designed to get more interviews for the best candidates coming in without a referral. Instead of sending a cold resume into an ATS and waiting, you complete a challenge built by Arrivia and submit a short video walking through how you approached it. You'll use AI the way you would on the job, and you'll show the thinking behind what you built.

Why that works in your favor:

• You show how you actually build and ship with coding agents, instead of hoping a resume gets it across.
• Your judgment with AI becomes visible, which no "proficient with AI coding agents" resume bullet can prove.
• One challenge puts you in front of the engineering team, scored on the work, with no referral required to get there.

The hiring manager reviews every completed submission, and the strongest candidates go straight to an interview round. No referral needed. Performance over pedigree. Proof over polish.

Arrivia offers competitive compensation, plus access to the private travel marketplace with deeply discounted cruises, resorts, and hotels, comprehensive medical, dental, and vision coverage, and a 401k with company match. Beyond the package, you get broad technical ownership and the chance to shape how an entire engineering organization adopts agentic development, on a team of curious, action-oriented builders that ships fast and stays current with where the field is going.

Apply by completing the challenge at provn.co, where the full role details live. Applications are open through July 31.
