Sr. Platform Engineer I

Role Overview

Sr. Platform Engineer I (Platform Engineering, Developer Experience) at NinjaTrader. You’ll design and build internal tools, workflows, and “golden paths” that make engineers across the organization more productive—helping teams build, test, ship, and operate software with less friction.

Responsibilities

• Define and maintain golden paths for service creation (service templates, starter kits, scaffolding tools) to move teams from zero to production-ready.
• Own developer onboarding workflows and maintain high-quality platform documentation.
• Establish and evolve CI/CD pipeline standards across the organization.
• Implement release automation patterns including rollout safety (e.g., canary deployments, progressive delivery) and automated rollbacks.
• Build and maintain internal platform portals, reusable infrastructure modules, and “paved road” workflows.
• Enable product engineering to provision resources, configure environments, and ship independently.
• Drive adoption via documentation, enablement sessions, and a consultative approach.
• Measure developer satisfaction and adoption metrics to continuously improve the platform experience.
• Collaborate with product engineering, infrastructure engineering, and operations to ensure platform tooling supports cross-platform needs.
• Translate engineering pain points into scalable platform capabilities.
• Embed security/compliance requirements into platform tooling and CI/CD pipelines (including SOC 2 and PCI-DSS).

Requirements

• 8+ years in platform engineering (posting is truncated after this point).

Nice-to-haves

• Experience spanning web, mobile, desktop, and trading platform delivery, and building self-service developer platforms.
