Senior Site Reliability Engineer

Dimensional Fund Advisors • Austin, TX

7d • Hybrid

About The Position

We are looking for a Senior SRE to serve as the operations owner for the developer tooling ecosystem that shapes how engineers work day to day, including Python and .NET toolchains and IDEs. This is a hybrid role balancing steady-state operations and engineering work that meaningfully advances the tooling and the people who depend on them. This role suits someone who is genuinely motivated by the pursuit of excellence – someone who takes pride in the products and services they own and is always looking for the next opportunity to raise the bar, whether that means eliminating a friction point in the local development experience or building automation that lets developers focus on code rather than tooling.

Requirements

• Bachelor’s degree in a technical field or equivalent practical experience
• 5+ years of experience in SRE, DevOps, platform engineering, or developer tooling-focused role
• Solid understanding of Python ecosystem tooling – dependency management (Poetry, uv), virtual environments, and packaging
• Familiarity with .NET development tooling and SDK management in an enterprise environment
• Proficiency in scripting and automation (Python, PowerShell, Bash, or similar)
• A track record of not just operating products and services but evolving them
• Strong communication skills and genuinely interested in partnering with developers across the organization
• Demonstrated ability to drive incidents to resolution and communicate clearly under pressure
• A bias toward automation and a low tolerance for repetitive manual work

Nice To Haves

• Experience leveraging SDLC platforms to deliver software solutions
• Experience building or maintaining internal developer portals or self-service tooling
• Exposure to IDE plugin or extension management at scale (VS Code, JetBrains, Visual Studio)
• Experience with developer experience metric frameworks
• Familiarity with container-based build environments or ephemeral CI runners

Responsibilities

• Serve as a primary escalation point for production support across each of the developer tooling ecosystems
• Own the operational reliability of developer tooling ecosystems, including Python toolchains (uv, Poetry, etc.), .NET SDKs, and IDE configurations and extensions
• Monitor product and service health and performance, proactively identifying and addressing issues before they impact developer productivity
• Maintain and continuously improve runbooks, escalation procedures, and operational documentation
• Collaborate with security to harden developer tooling configurations and manage software vulnerabilities
• Contribute to on-call rotations and maintain runbooks and escalation procedures
• Create and maintain standardized developer tooling configurations and distribution mechanisms – making it easy for engineers to get started, stay current, and stay unblocked
• Lead or contribute to developer experience initiatives, using data (build times, pipeline success rates, time-to-first-commit) to identify the highest impact friction points and build solutions that address them at scale
• Participate in architecture reviews and contribute to the overall platform roadmap

Benefits

• Dimensional offers a variety of programs to help take care of you, your family, and your career, including comprehensive benefits, educational initiatives, and special celebrations of our history, culture, and growth.
