Principal AI Platform Engineer

About the role

TradeStation is seeking a Principal Software Engineer to help build our AI Platform from the ground up. This role involves architecting and hands-on development of the MCP gateway, AI portal, identity layer, and agentic flows that serve as the foundation for our engineering organization. You will be responsible for turning emerging AI capabilities into secure, reliable, and reusable infrastructure to accelerate software delivery and client service.

We embrace an AI-First culture, where AI is a core part of daily workflows—used to enhance development, decision-making, client outcomes, and internal processes. If you join us, you’ll work in a culture where AI is how we operate, following governance standards to ensure ethical, secure, and transparent use.

Responsibilities

• Architect and hands-on build the core of the AI Platform: the MCP gateway, AI portal and skills marketplace, identity brokering layer, and agentic execution flows that the rest of engineering builds on
• Code the most complex or ambiguous solutions and set the technical bar for the platform
• Design secure-by-default integrations between internal systems and AI agents, with proper authentication, authorization, RBAC, and audit logging
• Build telemetry and observability to make AI usage and spec-driven development measurable across the organization
• Partner with engineering teams to turn their workflows into reusable skills, MCP servers, and agentic routines
• Establish patterns, guardrails, and golden paths for safe and quick adoption of AI tooling within governance standards
• Champion best practices in software development, testing, and deployment, ensuring scalability, reliability, and performance of platform services in a Kubernetes and DevOps environment
• Continuously evaluate emerging models, frameworks, and agent patterns and integrate useful ones into the platform

Requirements

• Bachelor’s degree or equivalent work experience
• Minimum 7 years of relevant software engineering experience
• Demonstrated experience designing and building platform, infrastructure, or backend services used by other engineering teams
• Deep, hands-on experience building and operating production backend services and developer platforms
• Mastery of 2 or more modern general-purpose programming languages, such as Python and TypeScript (Go or C# is a plus)
• Strong understanding of REST API design, GraphQL (building and consuming), and microservices architecture
• Hands-on experience with cloud platforms (e.g., AWS) and container orchestration tools (e.g., Docker, Kubernetes)
• Experience building on or integrating with large language models and agentic systems: tool and function calling, the Model Context Protocol (MCP), retrieval, and evaluation
• Solid grounding in identity and access management (OAuth2 / OIDC, SSO, RBAC); experience with Keycloak, Entra ID, or Auth0 is a strong plus
• Familiarity with scripting and automation (e.g., Bash, PowerShell) and CI/CD pipelines and infrastructure as code (e.g., GitLab CI, Helm)
• Comfort operating in ambiguity and enthusiasm for creatively solving problems without a pre-existing blueprint
• Excellent communication skills and ability to influence and collaborate with engineers across diverse teams
• Embraces AI as a core part of daily workflow and a partner in problem-solving

Desired Qualifications

• Hands-on experience building LLM-powered or agentic applications (MCP servers, tool-calling agents, retrieval / RAG)
• Python and/or TypeScript / Node development experience
• Identity and access management experience (Keycloak, Entra ID, or Auth0; OAuth2 / OIDC)
• Cloud architecture and deployment (AWS, EKS); hands-on Docker or Kubernetes experience
• Experience with observability and telemetry tooling
• Financial services or brokerage domain experience

Benefits

• Collaborative work environment
• Competitive salaries
• Yearly bonus
• Comprehensive benefits for you and your family starting Day 1
• Unlimited Paid Time Off
• Flexible working environment
• TradeStation Account employee benefits, as well as full access to trading education materials
