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.
