Define arrivia's multi-year vision for agentic engineering, and how we build, ship, and operate software at scale.

As a Principal Agentic Software Engineer, you are our foremost technical authority on agentic software development, a product-minded, full-stack engineer who defines how AI coding agents reshape the way we build and operate software at scale. Operating with full autonomy and company-wide scope, you set the multi-year technical vision and the engineering standards teams follow.

This role sets the technology direction behind arrivia, a leader in travel loyalty, membership, and cruise solutions, powering travel for millions of members.

You will make the highest-stakes architectural decisions that determine our competitive trajectory, and you will be the driving force behind our agentic engineering strategy, evaluating frontier models, designing human-agent collaboration patterns, and evolving our engineering culture.

You will partner directly with VP-level leadership to align technical strategy with business goals, represent arrivia's engineering externally, and serve as the final technical escalation point for our most complex challenges.

What You'll Own

• Own the technical vision: Define and own the multi-year technical vision and architecture for our travel platform, aligned with product and business strategy.
• Lead agentic strategy: Set the direction for how AI coding agents are adopted, governed, and optimized across all engineering teams.
• Make the biggest calls: Make the highest-impact architecture and technology investment decisions, weighing scalability, reliability, security, cost, and speed with company-wide consequences.
• Design the agentic framework: Evolve prompt libraries, MCP server ecosystems, agent governance, and quality gates for AI-generated code that set the standard for the whole organization.
• Architect enterprise MCP: Define how AI agents securely interact with internal APIs, databases, infrastructure, and third-party services across the full lifecycle.
• Evaluate the frontier: Assess frontier AI models and emerging frameworks, making build-vs-buy-vs-integrate recommendations that shape the roadmap.
• Lead complex initiatives: Lead the most complex cross-cutting technical efforts across teams and domains, from concept through production.
• Drive modernization: Define migration paths and patterns that transform legacy systems into scalable, cloud-native, agent-ready services.
• Set reliability standards: Establish SLO frameworks and operational excellence practices that protect the platform through rapid growth.
• Safeguard trust and governance: Define security architecture and partner with Risk, Security, and Compliance on AI governance and responsible-use policies.
• Grow engineering leaders: Mentor senior and staff engineers and build the next generation of technical leadership.

What You'll Bring
