What you’ll do   Technical leadership   Define the technical vision and architectural roadmap for The TradeDesk’s partner-facing platform   Lead the design of a scalable platform spanning federated GraphQL, RESTful APIs, SDKs, modular micro-frontends, integration workflows, developer tools, and polished web experiences.   Make hands-on contributions through prototypes, production code, architecture reviews, and code reviews across TypeScript/React front ends and C#/.NET GraphQL services.   Establish standards for schema and API consistency, backward compatibility, authorization, security, privacy, reliability, observability, Kubernetes-based operations, and SQL data modeling.   Simplify the partner journey from discovery and onboarding through testing, certification, launch, and ongoing optimization.   Turn shared needs across advertisers, data providers, publishers, and sellers into reusable platform services and front-end components rather than one-off integrations.   Guide cross-team decisions on schema governance, platform tooling, and architecture, balancing usability, scalability, reliability, security, privacy, and delivery speed.   Execution and influence   Partner with Product Management, Design, and engineering teams to shape the roadmap, technical approach, and delivery priorities.   Break down ambiguous, cross-team problems into clear technical plans, milestones, dependencies, and risks.   Drive alignment across teams that contribute to or consume the platform, communicating technical decisions and trade-offs clearly.   Define and improve measures of platform health and partner success, including integration time, adoption, API reliability, and developer experience.   Promote high standards for production of readiness, operational ownership, and continuous improvement.   Engineering excellence   Raise the engineering bar through thoughtful design and code reviews, technical mentorship, and practical guidance.   Coach engineers in system design, debugging, delivery, and operating services in production.   Lead by example as a trusted, hands-on technical partner who helps teams solve difficult problems and make durable decisions.   Foster a collaborative, inclusive environment where engineers share knowledge, challenge assumptions constructively, and take ownership of outcomes.     Who you are   You do not need to meet every qualification below. We are interested in candidates who demonstrate most of these capabilities and can learn the rest.   You have a sustained record of leading complex, high-impact software initiatives from definition through production operation.   You act as a Staff-level technical authority while remaining capable of and willing to contribute directly to the codebase.   You have experience leading engineers with different levels of experience and helping senior engineers and technical leads grow.   You have led initiatives involving several engineering and business teams, particularly where shared platform decisions affected teams outside your immediate organization.   You can turn an ambiguous product vision into a coherent architecture and an executable delivery plan.   You have strong knowledge of distributed systems, cloud platforms, service-oriented architecture, and modern software delivery practices.   You have experience designing durable APIs — GraphQL especially, including federation and schema evolution — as well as REST or event-driven integration interfaces.   You are experienced in modern frontend development: TypeScript, React, component-driven architecture, and data-rich single-page applications, ideally at monorepo scale.   You are proficient in C# and TypeScript/JavaScript, and comfortable with SQL and relational data modeling (SQL Server or similar).   You understand the needs of developers integrating with an external platform, including authentication and authorization, documentation, testing, versioning, observability, and supportability.   You can evaluate technical trade-offs involving usability, scalability, reliability, security, privacy, and delivery speed.   You communicate effectively with engineers, product leaders, commercial stakeholders, and external partners.   You lead with confidence and low ego. You advocate for well-reasoned decisions, invite competing perspectives, and change course when the evidence supports it.   You have significant professional software engineering experience, typically 10 or more years, or an equivalent record of technical impact.   You have experience directly managing engineers or a clear record of comparable people leadership.   You have a degree in computer science or a related discipline, or equivalent practical experience.   Experience that would be especially valuable   Building developer platforms, app marketplaces, or self-service onboarding systems.   Developing full-stack applications and data-rich partner experiences with React and .NET (or comparable stacks).   Working with federated GraphQL (Apollo Federation, HotChocolate, or similar) and schema governance across multiple teams.   Building or operating micro-frontend architectures and large frontend monorepos with modern build tooling (Bazel, pnpm workspaces, webpack/Vite).   Creating public APIs, SDKs, technical documentation systems, sandboxes, or automated certification tooling.   Working with identity, authorization, consent, data governance, or privacy-sensitive systems — for example, identity solutions such as UID2/EUID, persona-based access control, or entitlement systems.   Operating distributed services on Kubernetes and containers across multiple public clouds (AWS and Azure), with relational databases, feature-flag and experimentation systems, and modern observability tooling (Prometheus, New Relic, OpenTelemetry, or similar).   Working in advertising technology or with publishers, data providers, measurement partners, retailers, brands, or agencies.   Using AI-assisted experiences to improve documentation discovery, integration support, or developer productivity.     In accordance with various US state laws, the range provided is the Trade Desk's reasonable estimate of the base compensation for this role.
