At Frontiers, our purpose is simple yet ambitious: to make science open. We believe open science empowers the global scientific community to accelerate discovery and develop the solutions needed for healthy lives on a healthy planet.
We are one of the world’s largest and most influential open-access research publishers. Every article we publish is peer-reviewed and quality-certified, ensuring research is accessible to everyone, everywhere. To date, Frontiers research has been viewed over 4 billion times, demonstrating the real-world impact of science without barriers.
Joining Frontiers means being part of a general, mission-driven organization at the intersection of science, technology, and innovation — working alongside passionate colleagues who care deeply about advancing knowledge for the benefit of society.

Behind every product team sit theshared technical services that the whole publishing platform depends on. Today these are Identity & Access Management (IAM) and Messaging (transactional email and GDPR-compliant consent) — representative examples of this kind of shared service, with the portfolio expected to grow over time. They are owned by our Platform Shared Services team, and we are looking for a Platform Product Manager to own their strategy and roadmap.
Your customers are Frontiers' own engineering teams (and, increasingly, the services and agents they build): you run IAM and Messaging as products, measured by adoption, developer experience, reliability, integration time, security posture and cost— not user-facing metrics. You'll form a delivery triad with the team's Platform Engineering Manager and Senior Engineers: you own the What and Why, they own the How.
You will own the roadmap for 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 at the edge, OAuth client tooling, shared .NET libraries.
Messaging:



transactional/outreach email at scale (SendGrid, Mailgun), templating and A/B testing, deliverability (Everest, Uriports, Postmaster, SNDS), and a central GDPR consent authority (Subscription Management).
C#/.NET services on Microsoft Azure + Kubernetes (AKS); event-driven with RabbitMQ and Kafka; SQL Server, PostgreSQL, Redis, Elasticsearch.
Observability & AI: New Relic, Prometheus/Grafana; Own and evolve the roadmap for IAM and Messaging — prioritising against internal engineering demand, security/compliance requirements and platform scalability, and slicing big initiatives into iterative, valuable releases.
Co-design with engineering— work lock-step with the Platform Engineering Manager and Senior Engineers on architecture trade-offs, API contracts and service-level requirements. Own the service/API lifecycle— versioning strategy, deprecation planning and backward-compatibility decisions for services many teams depend on.
Be the primary point of contact for internal "customers" integrating with IAM and Messaging — a developer-facing product function: discovery, onboarding, support model, and a feedback loop that actually changes the roadmap.
Partner with Security, Architecture and Infrastructure— ensure IAM and Messaging meet compliance and security standards (OAuth/JWT, GDPR consent) and stay aligned with the Technology Framework.
Experience: 5+ years in Technical / Platform Product Management or engineering leadership, a significant portion in technical, platform, or developer-facing product roles.
Technical fluency (real):



solid software-engineering fundamentals — enough to engage credibly in architecture discussions, read technical docs, system diagrams and API specs unaided, and reason about trade-offs.
APIs as products: strong grasp of API design, versioning, documentation and lifecycle management (deprecation, backward compatibility).
Distributed-systems literacy: working knowledge of backend systems, messaging/event-driven architectures (Kafka, RabbitMQ, SQS) and authentication/authorization protocols (OAuth 2.0, OIDC, SAML, JWT).
Reliability & cloud awareness: familiarity with cloud infrastructure (Azure/AWS/GCP).
Bachelor's in Computer Science/Engineering or equivalent practical/technical experience — a technical/engineering background is preferred over a pure business/PM background given the hard technical requirements.
Professional-level English (spoken and written).
Experience with Microsoft Azure, Kubernetes (AKS), and modern CI/CD (GitHub Actions).
Experience facilitating InnerSource or community-driven contributions to shared services.
Interest or experience in Spec-Driven Development and AI coding assistants (Cursor, MCP).
Adoption & integration: number of teams/services on the supported IAM and Messaging paths; Reliability: SLAs/SLOs met for the owned services; support-request trend; quality and currency of contracts and docs.
Cost: run cost of the services (incl. email/deliverability spend) under control.
IAM and Messaging are leverage : get them right and every team at Frontiers ships faster and safer. All in service of a mission that matters: making science open for everyone.
