Tech Stack
About the role
- Own the end-to-end technical architecture for agentic systems, including multi-agent orchestration, memory management, and reasoning pipelines.
- Implement robust infrastructure to handle non-deterministic loops, including automated circuit-breakers, latency-aware orchestration (targeting P99 SLAs), and granular token/cost-observability.
- Define engineering patterns, design standards, and best practices for agentic application development across the entire organization.
- Mentor and grow Senior engineers; conduct deep-dive architecture reviews and drive high-stakes technical decision-making and be instrumental in the hiring process.
- Partner with AI Ops to ensure agentic workloads are efficiently built, served, and monitored with state-of-the-art observability.
Requirements
- 12+ years of software engineering experience, with at least 4+ years in technical leadership or principal-level roles.
- Deep hands-on experience shipping LLM-powered or agentic systems to production (utilizing frameworks like LangGraph, AutoGen, CrewAI, or custom-built runtimes).
- A proven track record of architecting distributed, high-availability systems. You understand that "it worked on my machine" is not the same as "it works at scale."
- Mastery of Python and modern backend frameworks. Deep familiarity with RAG pipelines, vector databases, tool-calling APIs, and multi-step reasoning. (TypeScript/Node.js is a plus).
- Ability to distill complex "black box" AI concepts into clear technical roadmaps for executive stakeholders and cross-functional partners.
- A desire to influence org-wide engineering culture, prioritizing code quality, observability, and rigorous testing in an AI-first world.
Benefits
- A competitive base pay
- Medical Benefits
- Discretionary incentive plan based on individual and company performance
- Focus on development: Access to a learning & development platform and opportunity for you to own your career pathways
- Flexible work policy
