Job description

Senior Fullstack Engineer: Agentic Infrastructure Team

Internet Brands is looking for a Senior Fullstack Engineer to join our Agentic AI team. You'll help build our AI capabilities from the ground up, designing and shipping tools, services, and intelligent agents that power AI experiences across our entire product ecosystem.

What You’ll Do

• Build and ship full‑stack AI applications: Create frontend experiences and backend systems that power real AI capabilities, iterating based on performance and user feedback.
• Own the full lifecycle: Take projects from idea through production deployment, ensuring quality, reliability, and scalability.
• Build foundational infrastructure: Develop search/retrieval services, tool execution layers (MCP servers), workflows, and intelligent agents.
• Establish measurement systems: Create feedback loops and performance tracking to continuously improve AI system behavior.
• Solve complex problems: Debug issues across the stack, identify root causes, and implement robust solutions.

What We’re Looking For

Foundation (Required)

• 5+ years shipping production code (frontend and backend).
• Strong programming fundamentals: We’ll primarily use JavaScript, Python and PHP, but value problem‑solving skills over specific language expertise.
• Backend development experience: Building workflows, APIs, state management, and async systems.
• Database knowledge: Working with both SQL and NoSQL databases.
• Frontend skills: Building responsive interfaces with modern frameworks (React, Vue, Angular, Svelte, etc.).
• Experience applying AI/ML in production: You've worked with LLMs or ML models in real applications, not just tutorials.

Working Style

• Ownership mindset: You identify problems, take initiative, and see things through.
• Pragmatic and adaptable: You choose the right tool for the job and aren’t afraid to learn new technologies.
• Systematic problem‑solver: You can debug complex systems and think through tradeoffs.

Good to Have

• Knowledge of AI evaluation, error analysis, and building feedback loops.
• Experience with agentic frameworks (LangGraph, Google ADK) or Model Context Protocol (MCP).
• Background in information retrieval or search systems.

Sound Like You?

Even if you don’t check every box, we encourage you to apply. We value problem‑solving ability, learning agility, and ownership over perfect resume matches. If you’re excited about building production AI systems and have strong full‑stack fundamentals, we want to hear from you.

At Internet Brands, we carefully consider a wide range of factors when determining compensation, including your background and experience. These considerations can cause your compensation to vary. We expect the compensation for this role to be in the low $100ks.

In addition to our awesome culture, we offer a comprehensive benefits package designed to support the health and well‑being of you and your family. Our benefits include health insurance options such as medical, dental, and vision coverage, flexible spending accounts (FSA) for medical and dependent care, short‑term and long‑term disability insurance, and life and AD&D insurance. We also provide a 401(k) retirement savings plan with a company match, paid time off (PTO), paid holidays, commuter benefits as well as access to our Employee Assistance Program (EAP) and well‑being coaching services. In addition, employees can take advantage of voluntary benefits such as home, auto and pet insurance, and discounted legal and financial services.
