VP of Engineering / CTO
About The Role
We’re hiring a
Staff Backend Engineer – Core AI Platform
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
Required Qualifications
What We’re Looking For
- 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
