Machine Learning Engineer, AI Agent Platform
Confirmed on the employer's own hiring board on Oct 18, 2026. First seen by Alion on Apr 13, 2026.
The Company
Arta is on an audacious and incredibly rewarding mission: to pave the way for people everywhere to lead more successful financial lives. Arta leverages AI and sophisticated digital tools-once reserved for ultra-high-net-worth individuals-and makes them accessible to a broader global audience. Think of it as your own digital family office, combining intelligent investment strategies, alternative assets, private market access, and smart automation to help you grow and protect your wealth effortlessly. We value trust, teamwork, and adaptability. Think: intelligent investing, personalized portfolios, and real-time trading, all backed by robust data infrastructure.
The Role
Arta is building the AI infrastructure for the next generation of wealth management.
We partner with leading financial institutions to power strategic initiatives that create real competitive advantage, particularly in making high-quality, personalised advice scalable.
Our platform enables intelligent agents to operate across core advisory workflows, from client servicing and suitability to portfolio research and analysis. These systems run in live, regulated environments and are embedded into how institutions serve their clients day to day.
What You Will Do
You will design and build production-ready agent systems that sit at the core of how financial decisions are supported and delivered.
Build the AI Agent Platform
Design and implement agent architectures (tool use, planning, memory, orchestration)
Build systems for LLM orchestration, prompt management, and workflow execution
Develop evaluation frameworks for agent quality, reliability, and safety
Create benchmarking pipelines to measure model and system performance over time
Enable Enterprise Deployment
Build infrastructure for self-hosted and multi-tenant deployments
Design systems that operate under enterprise constraints (security, latency, cost)
Develop APIs and platform abstractions for external partners
Bridge Research → Production
Translate rapidly evolving LLM capabilities into stable, production-ready systems
Partner with ML and product teams to integrate agents into real financial workflows
Improve reliability, observability, and failure handling of agent systems
Who You Are
5+ years building production ML systems or backend systems for ML-powered products
Hands-on experience with LLMs, agent frameworks, or applied ML systems
Strong Python skills and experience with modern ML tooling
Experience with agent systems, tool use, or LLM orchestration frameworks
Experience building evaluation / benchmarking systems for ML or LLMs
Experience designing systems beyond notebooks - APIs, services, pipelines
Strong systems thinking: latency, reliability, failure modes, tradeoffs
Location: Bay Area preferred (3 days/week in our Mountain View office). We're flexible for exceptional remote candidates on the West Coast.
Strong Plus
Experience with self-hosted models or enterprise AI deployments
Background in distributed systems or data infrastructure
Exposure to financial systems or high-stakes domains
What Makes This Role Different
This is not a research or prototype-focused role.
You will be responsible for shipping systems that operate in live financial environments. Your work directly supports institutional clients and real end users at some of the largest and fastest-growing financial institutions, not internal demos.
If you’re motivated by making agent systems work reliably at scale, in complex and regulated settings, this role will be a strong fit.
