About FrontiersAt 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 integral, 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. To learn more about our impact and culture, please watch this video. 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. 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. The Technical ContextYou 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 withRabbitMQ and Kafka; SQL Server, PostgreSQL,Redis, Elasticsearch.
Observability & AI: New Relic, Prometheus/Grafana;

What You'll Do
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.
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.
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.
Language: Professional-level English (spoken and written). Experience with Microsoft Azure, Kubernetes (AKS), and modern CI/CD (GitHub Actions). Interest or experience in Spec-Driven Development and AI coding assistants (Cursor, MCP). How We Measure Success in This RoleAdoption & integration: number of teams/services on the supported IAM and Messaging paths; quality and currency of contracts and docs.email/deliverability spend) under control.
