Senior Agentic Software Engineer (Remote US)

Senior Agentic Software EngineerArriviaRemote-US · Full-timeJob ContextArrivia 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. You operate with limited oversight and broad organizational scope, making the high-impact architectural calls that shape the platform's technical foundation. You work at organization scale rather than within a single team: you design the company's agentic workflow strategy, standardize coding agents like Claude Code, Cursor, and GitHub Copilot across engineering, establish the prompt libraries and best practices other engineers build on, and architect the MCP integration blueprint that defines how agents access internal tools and services. This role is Remote-US, working with a distributed team across US and international time zones (open to most states, with a few exceptions listed on the role page). Expect 8 or more years of full-stack and architectural experience and expert-level use of coding agents, across TypeScript/JavaScript, Python, or C#/.NET, a front-end framework like React, Next.js, Vue, or Angular, and cloud-native delivery on AWS, Azure, or GCP.You fit if you've been the person other engineers look to when they adopt a new way of working. You set direction and standards. You weigh innovation against risk and scalability at the platform level, and you've architected MCP server ecosystems for secure, structured agent access before. You bring judgment to every place agents touch the codebase, and you can bring a whole org along with you, not just your own team. Advanced prompt engineering, deep cloud-native architecture experience, and containerization and orchestration with Docker and Kubernetes round out the picture.How hiring works hereApplying 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 favorYou show how you actually architect and standardize agentic development, 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 strongest candidates go straight to an interview round. No referral needed. Performance over pedigree. Proof over polish.What's in it for youArrivia 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.
