About the Role

We’re hiring a Staff Engineer – AI Frameworks to architect and lead the development of the foundational multi-agent infrastructure powering the next generation of intelligent systems for financial institutions.

This role is not about plugging in pre-built models—it’s about designing and scaling custom AI orchestration frameworks that bind language models, memory, judgment modules, and tool use into autonomous systems that are trustworthy, composable, and policy-aligned.

You’ll work at the intersection of machine learning, distributed systems, and agentic reasoning, partnering with researchers, backend engineers, and product leaders to bring real-time, LLM-driven intelligence into production at scale.

This is a rare opportunity to define and build the AI runtime and execution architecture for mission-critical agents in a high-regulation, high-trust industry.

What You’ll Own

  • Architect a multi-agent AI framework for orchestrating LLMs, tools, memory, and decision modules in live user-facing systems

  • Build and optimize low-latency, distributed inference systems that meet real-time SLAs for transactional environments

  • Develop modular components for task planning, reward routing, fallback handling, and multi-turn reasoning

  • Design developer-facing APIs and tooling to allow AI product teams to safely extend and compose agentic functionality

  • Integrate vector stores, custom retrieval pipelines, model evaluators, judgment layers, and auto-tuning workflows

  • Drive the implementation of prompt tuning, reward modeling, and LLM-as-a-Judge techniques in production loops

  • Collaborate with research to productionize new RL, planning, or alignment strategies

  • Establish architectural best practices for extensibility, observability, and trust in AI-enabled systems

What We’re Looking For

Required Qualifications

  • 8+ years of backend or platform engineering experience, with at least 2 years building or deploying AI/ML systems

  • Prior hands-on experience building ML models or training pipelines—you know how models learn, behave, and break

  • Expert knowledge of LLM system design, agent architectures, and Reinforcement Learning techniques

  • Deep experience with Node.js, asynchronous architecture, and performance-critical backend systems

  • Proven track record building distributed, event-driven systems in high-throughput environments

  • Experience building real-time inference systems that integrate LLMs with retrieval, memory, or tool use

  • Strong systems design skills: designing modular, fault-tolerant, observable software at scale

  • Demonstrated ability to lead architectural design and cross-functional engineering initiatives

Preferred Experience

  • Experience building multi-agent systems or intelligent orchestration engines

  • Familiarity with vector databases, semantic search, and prompt engineering techniques

  • Comfort integrating ML eval frameworks and offline/online experimentation pipelines

  • Open-source contributions to LLM tooling or infrastructure a plus

What Makes This Role Special

  • You’ll define the core AI infrastructure powering autonomous financial workflows across millions of users

  • You’ll lead the engineering strategy behind multi-agent AI systems—designing how autonomous AI thinks, adapts, and acts

  • You’ll build for speed, scale, and compliance, solving real-world challenges in applied alignment, observability, and modularity

  • You’ll work with a team that combines world-class AI research, backend engineering, and product-first thinking to move fast with purpose

Compensation

Compensation is expected to be between $170,000 - $210,000. Exact compensation may vary based on skills and location.

What We Offer

  • Health: medical, dental, and vision insurance and wellbeing resources and programs
  • Time away: Public holidays and discretionary PTO package for flexible days off with manager approval
  • Financial: 401K, ESPP, Basic life and AD&D insurance, long-term and short-term disability
  • Family: parental leave
  • Development: Access to internal professional development resources.
