Position Summary Platform Engineering is part of the Architecture and Engineering team within TCW's Engineering Solutions organization. This team works alongside our Chief Architect to solve increasingly complex engineering challenges that empower internal developers through automation, frameworks, tooling, and custom platform solutions. As a Senior Software Engineer on the Platform Engineering team, you will serve as the primary maintainer of TCW's cross-team UI framework — a React-based single page application (SPA) framework built with Turborepo and a custom deployment pipeline. This framework is used by development teams across the organization, and you will be the central point of contact for feature development, bug resolution, developer support, and adoption guidance. In addition to the UI framework, you will contribute to Velocity, TCW's internal developer platform, and participate in broader Platform Engineering initiatives that span cloud infrastructure, automation, and developer tooling. The team delivers solutions using Go, .NET/C#, Python, and React/TypeScript, though prior Go experience is not required for this role. This role offers exceptional breadth of learning. Platform Engineering sits at the intersection of software development, cloud infrastructure, and developer tooling — giving you hands-on exposure to a wide variety of technologies and disciplines. If you are driven to grow as an engineer and want deep, practical experience with cloud-native solutions on Azure, this team will challenge and develop you well beyond the boundaries of a traditional front-end role. Essential Duties UI Framework Ownership: Maintain and evolve TCW's cross-team React/TypeScript SPA framework, including Turborepo monorepo management, build tooling, and the custom deployment pipeline. Developer Community Enablement: Partner with development teams across the organization to onboard them to the framework, address bugs, deliver new features, and provide architectural guidance on UI patterns and best practices. Platform Engineering Contribution: Contribute to Velocity and other Platform Engineering projects, including cloud-based solutions, CI/CD automation, and internal tooling. Leadership: Elevate engineering quality across the organization through documentation, presentations, and reusable patterns that promote consistency and developer productivity. Teamwork: Collaborate with an inclusive, cross-functional team to deliver high-quality solutions and support internal development teams at all levels. Required Qualifications Demonstrated professional experience building and maintaining React/TypeScript applications, preferably at a framework or platform level Strong proficiency with modern front-end tooling (Vite, Webpack, Turborepo, or equivalent monorepo/build systems) Experience working across development communities — supporting, guiding, and enabling other engineers (not just building for end users) Experience with CI/CD pipelines and deployment automation Experience with a public cloud provider (Azure preferred) Bachelor’s degree in computer science, Engineering, Mathematics, or 5+ years of relevant experience Professional Skills Qualifications Critical thinking above all else — must be willing to independently identify, research, and dig deep to solve complex and ambiguous problems without waiting for a prescribed answer Strong communication skills — comfortable presenting to and guiding engineers at all levels across the firm Committed to documentation — actively maintains living documentation for the UX framework to reduce tribal knowledge, ease the support burden, and enable teams to self-serve Ability to balance competing priorities across multiple teams with different needs and timelines Results-oriented with a developer-empathy mindset — thinking about the framework consumer, not just the framework Forward-thinking approach to front-end tooling, design systems, and SPA architecture Desired Qualifications Experience maintaining a shared component library or design system used across multiple teams Familiarity with accessibility standards (WCAG) and responsive design Experience with .NET/C# or Python (useful for cross-team Platform Engineering contributions) Public cloud certification(s) Unit and integration testing experience (Vitest, Playwright, or equivalent) Strong interest in AI tooling and AI-assisted developer workflows Passion for developer experience (DX) and software development best practices Experience in the financial industry Estimated Compensation Base Salary: For CA based position, the base salary range is $125k to $190k.
