By combining build and operations, we deliver agentic systems that are reliable, secure, and scalable in real-world use.Job Description
About the Role
We are evolving our chat experience from human-assisted to fully agentic. As an AI Agentic Software Engineer, you will help rewrite an existing production application into an end-to-end agentic platform, with a strong passion for customer experience and a commitment to building intuitive, high-quality interactions.
This role is for engineers who treat AI as a core part of the system—embedded across the full SDLC to deliver production-grade outcomes—while continuously advocating for the end user. You’ll work in a Google-centric stack using tools like ADK and Gemini Enterprise to build complex, agent-driven experiences that are not only intelligent, but seamless, trustworthy, and delightful for customers.
What You’ll Do:
Agentic & AI-Augmented Engineering
Design, build, and operate agentic systems that replace or augment human workflows
Apply AI across the SDLC, including:
Requirements and spec-driven development
System and agentic workflow design
AI-augmented coding and refactoring
AI-driven testing and defect remediation
Treat AI as a collaborating system, not a one-off tool
Evaluate and iterate on AI outputs (e.g., LLM-as-a-Judge)
Platform & Production Delivery
Build production-ready agent-based solutions with reliability, scalability, and observability
Implement agent-to-agent, agent-to-UI, and human–AI orchestration
Contribute to AgentOps, MLOps, and AI governance
Ensure ethical, compliant, and responsible AI use.
Collaboration & Influence
Clearly communicate how AI is used in your engineering workflows
Share patterns and best practices with the team
Partner with product, UX, and platform teams to deliver cohesive experiences.
What You’ll Need:
7+ years building agentic AI systems in production, or equivalent experience designing, shipping, and operating scalable, production-grade software (APIs, platforms, workflow engines, or customer-facing applications)
Hands-on experience with Agent Development Kit (ADK) and Python
Experience with Gemini Enterprise, or similar conversational AI platforms
Spec-driven development with AI integrated into the development lifecycle
Strong prompt engineering skills, including evaluation, iteration, and logging
Experience leveraging AI-assisted coding across multiple features or defects in parallel
Familiarity with AgentOps and production monitoring for agent-based systems
Experience with LLM-as-a-Judge or comparable evaluation techniques
Proven ability to design agent-to-agent, agent-to-UI, and human–AI collaboration patterns
Soft Skills: Curiosity to explore emerging AI capabilities, critical thinking to assess AI outputs, and adaptability in fast-moving, ambiguous environments.
