Application Platform Architect

Overview

Define and build the foundational architecture of Zeta's application platform, including microservices frameworks, APIs and shared libraries, with support for AI agents and agentic workflows.

What you'll do

• Define the technical vision and roadmap for the Zeta application platform to meet long-term business and engineering needs.
• Design and lead the implementation of core platform services, including reusable microservices, APIs and shared components that serve all applications.
• Architect and build the platform services and APIs that enable integration of AI agents, large language models (LLMs) and agentic workflows, and design scalable infrastructure to support them.
• Ensure the platform architecture scales with increasing load and complexity, with a focus on high availability, performance and fault tolerance.
• Create tools, frameworks and best practices that improve developer experience, accelerate development velocity and ensure consistency across applications.
• Research, evaluate and recommend emerging technologies, tools and architectural patterns.
• Partner with engineering, DevOps and security teams to embed security, monitoring and operational best practices into the platform's design and development lifecycle.
• Create and maintain comprehensive documentation, guidelines and governance standards for the platform's architecture and usage.

What you'll need

• 10+ years of experience in software engineering, with at least 3-5 years in a lead architect or principal engineer role.
• Extensive experience designing and building large-scale, distributed application platforms.
• Deep expertise in microservices architecture, RESTful APIs and event-driven systems.
• Proficiency in Java, Scala or Python.
• Strong experience with cloud platforms (AWS preferred) and cloud-native services.
• Experience with containerization and orchestration technologies (Docker, Kubernetes).
• Experience with DevOps practices, CI/CD pipelines and infrastructure as code (Terraform, Ansible).
• Excellent communication, presentation and leadership skills.

Nice to have

• Experience with AI/ML frameworks such as LangChain, LlamaIndex or similar, and a proven track record of architecting platforms to support them.
• Experience with service meshes (Istio, Linkerd) and API gateways.
• Familiarity with identity and access management (IAM) systems.
• Experience with security architecture, including threat modeling and secure-by-design principles.
• A track record of contributing to open-source projects or speaking at industry conferences.
