Key Tasks & Responsibilities:

• Own end-to-end solution design with a strong API focus, from initial concept through architecture decisions to implementation guidance, ensuring solutions are scalable, maintainable, secure, and aligned with enterprise standards.
• Collaborate closely with enterprise architects and drive solution proposals forward by presenting to architecture boards, securing stakeholder buy-in, and shepherding designs from approval through delivery.
• Drive stakeholder alignment across product, platform, security, and business functions; act as the bridge between the team and the wider organization on strategic technical developments.
• Champion the creation and usage of API templates, SDKs, reusable services, and the Internal Developer Platform (Backstage) to support the Pharma Commercial.
• Lead the adoption of Composable Architecture principles across Pharma Commercial and guide engineers to apply them effectively.
• Define and enforce team-based standards for design patterns, programming tools, and techniques; select appropriate methods and ensure their effective application.
• Review systems designs of our product squads to ensure appropriate technology selection, efficient use of resources, and effective integration across multiple systems and technologies.
• Validate solution approaches through appropriate prototyping methods, choosing the most suitable technique for each context.
• Own delivery outcomes in a high-performing team, balancing quality and time-to-market by crafting pragmatic compromise solutions when constraints demand trade-offs.
• Leverage AI coding assistants effectively and promote their productive adoption within the team.
• Design and govern reusable components (APIs, SDKs, templates) that are discoverable, self-describing, and ready for consumption by AI coding assistants and autonomous agents—with clear contracts, machine-readable metadata, and up-to-date documentation.

• Presented solution designs and technical proposals to architecture boards, governance forums, or business stakeholders, and incorporated their feedback into final designs.
• Owned API or platform standards across multiple teams, with evidence of cross-team uptake (e.g. shared templates, SDKs, or design patterns in production use).
• Co-authored or reviewed architecture decision records (ADRs) in collaboration with enterprise architects, aligning solution designs with enterprise-wide standards and technology roadmaps.
• Navigated cross-team dependencies to deliver integrated solutions end-to-end, documented through design artifacts, decision logs, or delivery retrospectives.
• Excellent experience with component design as part of Composable Architecture principles like MACH, especially with an API-first and event driven integration strategy.
• Excellent experience working in agile teams using Scrum or Kanban.
• Excellent experience in programming with Python and TypeScript (Node.js) and at least one other, strongly typed, compiled language like C#, Java, or Kotlin; experience with other languages is a plus.
• Excellent experience with software version control using Git and collaborative development via GitHub.
