Sr. AI Engineer - Agentic Frontend

Sr. AI Engineer - Agentic Frontend

A high-growth technology company building AI-powered software for US government customers is looking for a Senior AI Engineer who lives at the intersection of frontend engineering and LLM-powered agents. The company’s AI agent has seen rapid adoption over the past year, and the next frontier is making that agent autonomously operate the product’s user interfaces — clicking, navigating, filling forms, invoking tools, and driving deterministic workflows through the UI on behalf of users.

This is not a typical AI engineering role. You won’t just be building models or pipelines — you’ll be teaching an LLM-powered agent to see, understand, and interact with complex frontend surfaces the way a power user would, but faster and at scale.

What You’ll Do

• Design frontend architectures with explicit state machines, action models, and structured DOM representations that an AI agent can reliably perceive and act on
• Build the integration layer between LLM reasoning and UI actions — translating agent intent into deterministic, verifiable interactions with the product interface
• Develop agent skills that are tightly coupled to specific UI surfaces: data tables, dashboards, search interfaces, forms, and visualization tools
• Create telemetry and evaluation frameworks that measure how accurately and reliably the agent interacts with the frontend (click accuracy, workflow completion rates, error recovery)
• Collaborate with frontend and product teams to make existing interfaces more agent-friendly without degrading the human user experience

What We’re Looking For

• You have experience building an LLM-powered agent interacting with a real frontend — not just calling APIs, but actually navigating and operating a UI agentically
• Strong frontend engineering skills: you’ve built complex UIs yourself and understand how to structure them for both human and machine interaction
• Experience designing state and action models for AI-driven interfaces (agent-controlled navigation, tool invocation through UI, deterministic UI workflows)
• Hands-on experience with agent frameworks (Claude Agent SDK, OpenAI Agent SDK, or similar)
• Understanding of how to make LLM outputs reliable enough for UI automation (structured outputs, guardrails, fallback patterns, retry logic)
• Startup mindset — comfort with ambiguity, speed, and building from scratch

What Skills Do You Need

• 5 years of experience in software engineering, with meaningful time spent on both frontend development and LLM/ML-powered systems
• Advanced Python skills; proficiency with modern frontend frameworks (React, Next.js, or similar) is expected
• Hands-on AWS / cloud infrastructure experience
• Familiarity with Git and modern development practices
• Active or obtainable US security clearance is a plus

Compensation:

• Base Salary based upon experience but expect around $175,000
• 20-30% bonus - paid quarterly
• Equity - between $125,000 - $175,000 with 4 year vest
• Unlimited PTO
• 401(k) with 4% immediate vesting
• Professional development reimbursement

Please Note:

• You must be a US Citizen
• This is a Full-time, on-site (5 days) position in Pittsburgh, PA
• Role may include some travel - up to 10% - mainly between Pittsburgh and Washington DC area
• We offer relocation assistance if you are not currently local to the Pittsburgh area.
