Principal AI Platform Engineer
TradeStation Principal AI Platform Engineer
Summary
Hands-on principal engineer who builds TradeStation's internal AI platform from scratch — the MCP gateway, AI portal, identity brokering layer, and agentic execution flows other teams build on. Core stack: Python/TypeScript (Go/C# a plus), AWS, Docker/Kubernetes, LLM/MCP integration, and OAuth2/OIDC identity (Keycloak, Entra ID, Auth0).
What We Are Looking For:
- 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
- Take a hands-on approach to 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 the telemetry and observability that make AI usage and spec-driven development measurable across the organization
- Partner with engineering teams across the firm to turn their workflows into reusable skills, MCP servers, and agentic routines
- Establish patterns, guardrails, and golden paths so teams can adopt AI tooling quickly, safely, and within governance standards
- Champion best practices in software development, testing, and deployment, and ensure the scalability, reliability, and performance of platform services in a Kubernetes and DevOps environment
- Continuously evaluate emerging models, frameworks, and agent patterns and fold the useful ones into the platform
- Deep, hands-on experience building and operating production backend services and developer platforms; you are a builder first
- Mastery of 2 or more modern general-purpose programming languages, such as Python and TypeScript. Experience with 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 with CI/CD pipelines and infrastructure as code (e.g., GitLab CI, Helm)
- Comfort operating in ambiguity and an enthusiastic willingness to creatively solve problems for which there is no pre-existing blueprint
- Excellent communication skills and the ability to influence and collaborate with engineers across diverse teams
- Embraces AI as a core part of the daily workflow and a partner in problem-solving
- 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
- 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
- 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
- Pay Range (US) $155-175K (Countries outside of the US have differing ranges in accordance with local labor markets)
