About The Position

The Architecture Team drives Taskrabbit's Platform Modernization efforts, guiding engineering teams toward our Target State Architecture (TSA). As a Software Architect, you'll serve as an embedded representative of the Architecture team, partnering with engineering teams across the platform to accelerate their modernization work. You'll operate as a subject matter expert on platform modernization within a small team of architects, applying AI-assisted and Spec-Driven Development (SDD) practices to help teams build new components using our Target State Architecture stack of technologies. This role is hands-on and results-oriented: pairing directly with engineers and technical leads, not just advising from the sidelines.

Requirements

8+ years of professional experience in software development, with a primary focus on building and scaling backend systems.
Demonstrated experience with distributed systems and event-driven architecture.
TypeScript/Node.js experience preferred; candidates with a background in another strongly typed language (e.g., Java, .NET) will also be considered.
Experience with containerization and containerized application deployment.
An enthusiast for AI tooling and AI-assisted development practices, with a proven track record of applying them professionally.
Excellent communication skills, with the ability to build consensus and keep technical design discussions professional and productive, even when opinions differ strongly.
Willingness to lead, speak up, and be visible and vocal in Architecture and team design meetings.
Comfort pairing directly with engineers and technical leadership, not just producing documentation or recommendations.

Nice To Haves

Experience with Kubernetes (K8s).

Responsibilities

Acting as the Architecture team's representative to assigned engineering teams, driving platform modernization projects in accordance with the TSA.
Applying AI tooling and Spec-Driven Development practices to help teams modernize the parts of the platform they own.
Pairing with engineers and technical leadership to unblock modernization work and transfer architectural patterns directly into team practice.
Serving as a subject matter expert on platform modernization, advising on migration approach, sequencing, and risk.
Advocating for TSA-aligned solutions in technical discussions, including working through design discussions with engineering leads and other stakeholders.
Collaborating with a small team of architects to maintain consistency across modernization efforts platform-wide.
Writing and reviewing Technical Design Documents (TDDs) and RFCs, and coaching authors to strengthen their proposals.
Defining standards for tooling, coding, processes, AI usage, and documentation strategies that make modernization repeatable across teams.
Engage directly with projects and drive results forward — TDDs, code, and outcomes.
