## Description

This is a full-time role based in Austin, TX as part of Sixth Street's growing technology team. We are building and evolving a cloud-native platform that enables teams across the firm to build, ship, and operate secure, scalable software. We are a lean, high-impact team where everyone wears many hats. We do not work in isolation; we are deeply connected with our developers to ensure the platform we build solves real-world problems. On our team, you will treat our platform as a product. You will be responsible for the "Golden Paths" that reduce cognitive load for our developers, while balancing technical excellence with deep developer empathy. You will work closely with our Infrastructure and Security teams on behalf of our developers and analysts who use our platform.

About Our Stack

 * AWS-centric: Lambda, ECS (Fargate), RDS, S3, CloudFront, ElastiCache
 * Infrastructure as Code: CDK for IaC, Terraform a plus
 * Tooling: Ownership of GitOps and CI/CD tooling; GitHub Actions
 * Backend: Python-centric (with some Java and Julia); Frontend: TypeScript/React
 * Observability: OpenTelemetry standards and shared collectors
 * AI: AI Gateway and shared AI platform services for secure model access and governance

Core Responsibilities

 * Platform Strategy: Drive cross-team platform initiatives; facilitate alignment, adoption, and migration plans across the Engineering organization.
 * Self-Service & DevEx: Build and evolve self-service platform capabilities (e.g., "Golden Paths") that reduce cognitive load and accelerate delivery via templates, libraries, and sample applications.
 * Mentorship & Standards: Mentor engineers, analysts, and non-technical stakeholders with empathy. Set high-bar engineering standards for platform codebases and practice a disciplined approach to problem-solving (SOLID, DDD, etc.).
 * Product Mindset: Treat the platform as a product with active involvement in our roadmap, feedback loops with developers, documentation, and iterative UX improvements.
 * Observability & Telemetry: Refine and optimize the org-wide instrumentation "Golden Path" for metrics, logs, and traces. Enable teams through high-quality documentation, examples, and targeted one-on-one partnering.
 * AI Enablement: Evolve our AI platform capabilities, including AI gateway services and governance patterns. Use AI tools to plan, develop, and validate solutions as a key member of one of the firm's primary AI teams.
 * Deployment & Standards: In collaboration with our developers, evolve the GitOps and CI/CD tooling strategy. Encourage "Golden Path" deployment patterns, secrets management best practices, configuration, and runtime standards.
 * Strategic Partnerships: Maintain a close partnership with the Security and Cloud Infrastructure teams to ensure platform patterns are secure and resilient.
 * Operational Excellence: Help define the future of our platform's reliability. This is an area ripe for ownership-you will have the opportunity to shape our evolving SLO/SLI strategy, incident response patterns, and on-call expectations.
