About the Job

Requirements

  • A sustained record of leading complex, high-impact software initiatives from definition through production operation.
  • Ability to act as a Staff-level technical authority while contributing directly to the codebase.
  • Experience leading engineers with different levels of experience and helping senior engineers and technical leads grow.
  • Experience leading initiatives involving several engineering and business teams, particularly where shared platform decisions affected teams outside the immediate organization.
  • Ability to turn an ambiguous product vision into a coherent architecture and executable delivery plan.
  • Strong knowledge of distributed systems, cloud platforms, service-oriented architecture, and modern software delivery practices.
  • Experience designing durable APIs, especially federated GraphQL and schema evolution, as well as REST or event-driven integration interfaces.
  • Experience in modern frontend development using TypeScript, React, component-driven architecture, and data-rich single-page applications, ideally at monorepo scale.
  • Proficiency in C# and TypeScript/JavaScript, and comfort with SQL and relational data modeling such as SQL Server or similar.
  • Understanding of developers' needs when integrating with an external platform, including authentication and authorization, documentation, testing, versioning, observability, and supportability.
  • Ability to evaluate technical trade-offs involving usability, scalability, reliability, security, privacy, and delivery speed.
  • Significant professional software engineering experience, typically 10 or more years, or an equivalent record of technical impact.
  • Experience directly managing engineers or a clear record of comparable people leadership.
  • A degree in computer science or a related discipline, or equivalent practical experience.

Responsibilities

  • Define the technical vision and architectural roadmap for the 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.
  • Contribute hands-on 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.
  • 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 readiness, operational ownership, and continuous improvement.
  • Raise engineering standards through 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 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.

Desired Qualifications

  • Experience building developer platforms, app marketplaces, or self-service onboarding systems.
  • Experience developing full-stack applications and data-rich partner experiences with React and .NET or comparable stacks.
  • Experience with federated GraphQL, including Apollo Federation, HotChocolate, or similar, and schema governance across multiple teams.
  • Experience building or operating micro-frontend architectures and large frontend monorepos with modern build tooling such as Bazel, pnpm workspaces, webpack, or Vite.
  • Experience creating public APIs, SDKs, technical documentation systems, sandboxes, or automated certification tooling.
  • Experience with identity, authorization, consent, data governance, or privacy-sensitive systems, such as UID2/EUID, persona-based access control, or entitlement systems.
  • Experience operating distributed services on Kubernetes and containers across multiple public clouds such as AWS and Azure, with relational databases, feature-flag and experimentation systems, and modern observability tools such as Prometheus, New Relic, or OpenTelemetry.
  • Experience in advertising technology or with publishers, data providers, measurement partners, retailers, brands, or agencies.
  • Experience using AI-assisted experiences to improve documentation discovery, integration support, or developer productivity.
