Job description

About Frontiers

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 global, 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.

The Mission

At Frontiers, we are rewriting the rules of scientific publishing. Behind every product team sit theshared technical services the whole publishing platform depends on. Today these areIdentity & Access Management (IAM)andMessaging(transactional email and GDPR-compliant consent) — examples of this kind of shared service, with more likely over time — owned by ourPlatform Shared Servicesteam. We are looking for aPlatform Engineering Managerto lead the team that builds and runs them.

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 centralGDPR consent authority(Subscription Management).
• Core stack:C#/.NET services on Microsoft Azure + Kubernetes (AKS); event-driven with RabbitMQ 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; esc … etc.

• Management experience:minimum4 + years directly managing engineering teams, in addition to prior hands-on software engineering experience.
• Delivery track record:proven delivery ofbackend, platform, or infrastructure services; experience managing teams responsible forshared/platform services (authentication, messaging, APIs)strongly preferred.
• Technical depth (to steer, not to code daily):solid background inbackend engineering and distributed systems— enough to guide decisions on authentication and messaging infrastructure and review design proposals with senior engineers.
• Reliability & delivery practices:working knowledge of cloud infrastructure, CI/CD, and service reliability (SLAs/SLOs, incident management).
• Platform / shared-services understanding:how internal engineering teams operate asservice providersto the rest of the org.
• People & delivery balance:organised and outcome-driven, comfortable balancing people management (~60%) with technical/business activities (~40%).
• Planning:budget/resource planning experience for a team.
• Communication & judgement:clear communicator across technical and non-technical stakeholders; sound decision-making and comfort resolving ambiguity.
• Language:Professional-level English (spoken and written).
