About the Role

As an Agentic Software Engineer III, you are an experienced, product-minded, customer-focused, full-stack engineer who designs, builds, and ships complex features and subsystems using AI coding agents as core development tools. Working under general direction with significant autonomy, you own technical delivery end to end, from design through production, and lead technical efforts within your team, using tools like Claude Code, Cursor, and GitHub Copilot to multiply your impact.

You make complex decisions on system design and cross-component integration, balancing delivery speed, scalability, and long-term maintainability, with results reviewed at the outcome level rather than task by task. You actively mentor junior engineers, contribute to architectural decisions, and drive quality standards within your team.

This role is based onsite at arrivia's headquarters in Phoenix, AZ. Applicants must be legally authorized to work in the US without sponsorship now or in the future.

What You'll Do

• Design, develop, and deliver complex features and services as a key contributor on a full-stack product development team
• Write clean, testable, peer-reviewed, and optimized high-performance code, whether authored manually or collaboratively with AI agents
• Review and validate AI-generated code for correctness, security, performance, and maintainability, helping set quality standards within the team
• Build and improve internal agentic workflows that automate repetitive engineering tasks such as testing, documentation, and code review triage
• Build and configure Model Context Protocol (MCP) integrations that connect AI agents to internal tools, data sources, and platform services
• Revitalize services and architectures that have outlasted their original implementations through refactoring, migration, and cloud-native design patterns
• Safeguard the privacy, security, and trust of members' sensitive data in partnership with Risk and Security teams
• Participate in establishing and meeting backend and system SLOs to protect the platform through future growth
• Mentor junior engineers on effective development practices, code quality, and productive use of AI-assisted development tools

What We're Looking For

• Bachelor's degree in Computer Science, Computer Engineering, or equivalent experience
• 5 to 8 years of full-stack development experience building web applications and services
• 2+ years of hands-on experience using AI coding agents (Claude Code, Cursor, GitHub Copilot) in professional development workflows
• Strong proficiency in two or more of TypeScript/JavaScript, Python, or C#/.NET
• Deep experience with a modern frontend framework: React, Next.js, Vue, or Angular
• Experience architecting and deploying applications on AWS, Azure, or GCP
• Working knowledge of the Model Context Protocol (MCP) and experience configuring MCP servers
• Working knowledge of Azure AI Foundry, RAG, LangChain, and graph-based data technologies (GraphRAG, GraphDB)
• Experience with real-time streaming or distributed messaging platforms such as Redis, Kafka, or RabbitMQ
• Experience with containerization (Docker) and CI/CD pipelines
• Agile software delivery experience

How to Apply

To apply for this role, you must create an account on provn.co and submit all required application artifacts. Resume only applications may be considered, but candidates who complete a full application are reviewed with priority.

How hiring works here: Referrals are king for getting an interview. But what if you don't have a referral? Applying with Provn is designed to help you get more interviews. Instead of sending a cold resume into an ATS and waiting, you will complete a challenge built by arrivia and submit a short video walking through your approach. No time limit. No timers. No restrictions on AI usage. Show how you build with AI.

• You show how you actually build and ship with coding agents, instead of hoping a resume communicates your skill clearly.
• 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. Priority without a referral!

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.
