About the Role
As a Senior AI Engineer on the agent platform team, you will architect and deliver complex AI agent systems, build production AI agent systems on top of modern LLM APIs, contribute to agent observability and evaluation practices, adopt progressive delivery practices, participate in cross-cutting design reviews, and mentor other engineers. You will own meaningful systems end-to-end alongside a highly capable team building the next generation of legal AI agents.
Responsibilities
- Architect and deliver complex AI agent systems end-to-end, including multi-component pipelines, tool integrations, and multi-step reasoning, for the initiatives you own.
- Build production AI agent systems on top of modern LLM APIs, agent SDKs, and orchestration/runtime infrastructure, integrating cleanly with existing platform services.
- Contribute to agent observability and evaluation practices (tracing, automated evals, and quality/drift detection) so regressions in agent behavior get caught before they reach customers.
- Adopt and extend progressive delivery practices, like feature-flagged rollout and earlier-stage quality signals, as the team raises its bar for release velocity and stability.
- Participate in cross-cutting design reviews and technical decisions (RFCs/ADRs), bringing sound technical judgment to how new systems fit together.
- Mentor other engineers on the team, sharing expertise and modeling how to use AI-native, agentic development practices effectively.
- Collaborate with product and engineering peers to translate requirements into solid technical designs.
Requirements
- Strong experience architecting and shipping production software systems, including hands-on experience building AI/LLM-powered products or agentic systems (not solely classical ML/data science).
- Direct experience building with modern LLM APIs, agent frameworks/SDKs, or agent-to-tool integration protocols.
- Experience owning complex technical projects end-to-end, from design through production delivery.
- Strong backend engineering fundamentals, including distributed systems design, service architecture, and cloud infrastructure.
- Experience with production reliability and observability practices: monitoring, evaluation pipelines, incident response, and quality regression detection.
- Ability to mentor other engineers and contribute to a strong technical culture.
- Comfort working with high autonomy on a fast-moving, senior-heavy team that builds with AI-native/agentic engineering practices.
- Experience with developer-facing platforms, plugin/extension systems, or integration ecosystems.
- Familiarity with progressive delivery practices (feature flagging, phased rollout, blue/green deployment) at scale.
- Experience with managed agent runtime infrastructure (e.g., AWS Bedrock AgentCore or similar).
- Domain expertise in legal, regulated, professional-services, or other fiduciary domains is a plus, but not required.
