This pivotal role involves taking complete ownership of the architectural design and implementation that ensures our autonomous agents operate with unparalleled efficiency, security, and responsiveness. You will be instrumental in maintaining strict sub-second latency targets (under 1 second) across all critical operations, including sophisticated agent routing, the application of banking-grade security guardrails, and the secure, PII-safe execution and guardrails of tool calls.</span></h2> <h2><span>Beyond architecture, you will serve as the primary technical lead, guiding the strategic direction and hands-on development across several critical areas. This includes optimizing agent routing mechanisms, enhancing dynamic planning capabilities, evolving memory management systems for optimal token usage, establishing robust evaluation frameworks, and pioneering RL-based prompt tuning techniques. Your contributions will directly impact the reliability, safety, and performance of our next-generation AI agents.</span></h2> <h3><strong>What You’ll Do</strong></h3> <h2><span>This role demands a multifaceted technical leader capable of both high-level design and hands-on implementation. Your responsibilities will include:</span></h2> <ul> <li><strong>Lead Design and Implementation of Advanced Routing:</strong> Spearhead the architectural design and hands-on implementation of hierarchical and plan-based routing systems for our autonomous agents. A critical aspect of this will be enforcing tight latency budgets, specifically targeting performance within an 800–1500 ms window to ensure seamless user interactions and agent responsiveness.</li> <li><strong>Build Secure PII Pipelines:</strong> Develop and implement robust PII (Personally Identifiable Information) masking and transactional guardrails. This involves designing secure data flows and also rigorously enforcing idempotency and transaction safety across all external tool calls made by our agents, ensuring data integrity and compliance.</li> <li><strong>Own Model Selection and Inference Strategy:</strong> Drive the strategic selection and optimization of inference models. This encompasses evaluating and integrating a diverse range of models, including large language models, as well as fine-tuned or custom small models. You will also be responsible for leveraging high-performance inference engines to maximize throughput and minimize latency.</li> <li><strong>Design Efficient Memory Layers:</strong> Architect sophisticated memory layers for our agents. This includes designing short-term rolling windows for immediate context, retrieval memory for efficient information access, and audited long-term state management, all engineered to minimize token usage and optimize computational resources.</li> <li><strong>Ship Comprehensive Observability:</strong> Implement comprehensive observability solutions crucial for understanding and debugging agent behavior. This involves shipping systems for per-turn token and latency budgeting, detailed attribution (identifying which prompt or tool consumed what resources), and proactive red-flag alerting for anomalous behavior or performance degradation.</li> <li><strong>Stand Up Evals &amp; Re-inforcement learning:</strong> Establish and maintain robust evaluation frameworks and auto-evolution loops. This includes building comprehensive regression suites to track performance over time, developing sophisticated reward models for agent behavior optimization, and implementing bandit algorithms for dynamic, data-driven selection of prompts, models, and tools.</li> <li><strong>Mentor and Elevate Standards:</strong> Act as a technical mentor for senior engineers within the team, fostering their growth and development. You will also be responsible for setting and upholding high standards for code quality, defining best practices for incident response, and establishing effective change management processes to ensure smooth and reliable system evolution.</li> </ul> <h3><strong> </strong></h3> <h3><strong>What We’re Looking For</strong></h3> <h4><strong>Required Qualifications</strong></h4> <h2><span>To succeed in this role, you should possess a strong foundation in distributed systems and practical experience with AI agent technologies:</span></h2> <ul> <li><strong>Extensive Distributed Systems Experience:</strong> 8+ years of professional experience in designing, building, and maintaining high-throughput, low-latency distributed systems.
