These are high-blast-radius services consumed org-wide, so you'll balance shipping new capability with reliability, security and backward compatibility - treating the services as products for internal engineering customers. You'll form a delivery triad with the team's Platform Product Manager (who owns the What/Why) and your Senior Engineers (who drive the How). The Technical Context You will lead delivery across the team's shared-service lines - today IAM and Messaging. * IAM: OAuth 2.0 / OIDC (Ory Hydra), JWT authorization, fine-grained authz via a Permission API (Ory Keto), Azure APIM, OAuth client tooling, shared .NET libraries * Messaging: transactional/outreach email at scale (SendGrid, Mailgun), templating and A/B testing, deliverability tooling, and a central GDPR consent authority (Subscription Management) * Core stack: C#/.NET services on Microsoft Azure + Kubernetes (AKS); event-driven withRabbitMQ and Kafka; SQL Server, PostgreSQL,Redis, Elasticsearch * Delivery & reliability: CI/CD, observability (New Relic, Grafana), SLAs/SLOs and incident management * Ways of working: Spec-Driven / AI-First Delivery (PRDs/SDDs in git, the Technology Framework as executable context, Cursor, MCP) - available to help the team deliver faster and more safely What You'll Do * Lead the team day to day - oversee operations, resource allocation and task assignment across the IAM and Messaging portfolio * Turn roadmap into execution - translate the shared-services roadmap and portfolio objectives (owned with the Platform PM) into actionable engineering plans; ensure delivery aligns with department and wider engineering goals * Own team delivery - for authentication, messaging and related infrastructure: coordinate resources, manage risk, and deliver outcomes for the many teams that depend on these services * Partner with the Platform Product Manager - align roadmap priorities with technical feasibility, reliability and platform health; push back with technical reality where needed * Guide technical direction with your Senior Engineers - you don't need to be hands-on daily, but you provide enough depth to steer decisions on authentication and messaging infrastructure and to review architecture and design proposals * Develop people - set clear expectations, give regular feedback, support career growth, and run performance management for the team * Own reliability & operational excellence at the team level - SLAs/SLOs, incident management, and blameless post-incident follow-through; protect the team from unbounded toil * Improve process - identify and implement improvements that increase delivery efficiency and reliability across the team and portfolio * Represent the team cross-functionally - drive alignment with the engineering teams that consume shared services; elevate and manage significant technical/delivery risks to senior leadership, * Delivery: predictable, healthy throughput against the shared-services roadmap; risks surfaced and managed early * Reliability: SLAs/SLOs met for owned services; incident trend and quality of post-incident follow-through * People: team health, retention, growth and clear performance management * Consumer outcomes: satisfaction/adoption from the engineering teams that depend on IAM and Messaging * Security & compliance: the team's output meets the Technology Framework bar (OAuth/JWT, GDPR consent), You'll lead the team behind two of Frontiers' highest-leverage capabilities: get identity and messaging right, and every product team ships faster and safer. It's a rare mix of real people leadership , technical direction on interesting distributed systems , and platform-as-a-product thinking - all in service of a mission that matters: making science open for everyone.
