Requirements
  • Location: Remote in Europe
  • Strong hands-on experience with TypeScript/Node.js and PostgreSQL in production backend systems
  • Deep knowledge of identity and authentication standards: OAuth 2.0, OIDC, SAML, JWT, and session management
  • Proven experience designing and operating distributed systems at scale – you understand the failure modes and trade-offs, not just the happy path
  • Security-first mindset – you reason about threat models, trust boundaries, and least-privilege by default
  • Self-directed and autonomous; comfortable owning problems end-to-end and collaborating effectively across a remote, distributed team
Responsibilities
  • Design and build core authentication and authorization infrastructure
  • Implement and evolve identity protocols - OAuth 2.0, OIDC, SAML/SSO, session management, and JWT - powering secure access for hundreds of thousands of developers and their projects
  • Own the reliability, correctness, and security posture of identity services across our distributed platform, from API gateway to backend services to the login UI
  • Identify architectural improvements and drive them from initial design through production, with a security-first lens at every step
  • Build the identity layer for AI and agentic workflows
  • Design and implement agent attribution - establishing verifiable, auditable identity for AI agents acting on behalf of users and organizations at platform scale
  • Collaborate with platform and product teams to define the identity primitives that underpin Sanity's AI Content Operating System, including authorization models for agentic contexts
  • Work end-to-end across backend services (Node.js/TypeScript), PostgreSQL, and frontend auth flows - owning features from design through delivery
  • Participate in code reviews, architectural discussions, and incident response; contribute to on-call for identity services
  • Partner closely with security, platform, and product teams on cross-cutting concerns and help set the technical direction for the Identity domain
Desired Qualifications
  • Experience with Go, Lua, or Google Cloud Platform is a plus

Sanity Unveils AI-Powered Content Operating System to Enable Scalable AI Content Operations

Sanity unveils ai-powered Content Operating System to enable scalable AI content operations. Sanity has announced the evolution of its platform into a Content Operating System for the AI era. The platform is designed to enable organizations to gain access to the infrastructure needed to build, automate, and scale AI-based content operations. It is an intelligent backend for teams using AI across digital experiences. The platform is built on three key principles: modeling business data effectively, automating workflows, and supporting flexible integrations. It is designed to enable organizations to effectively manage their content ecosystems while supporting AI-based applications in production environments. By providing a structured content modeling solution alongside automation and AI-based infrastructure, Sanity claims that its platform is an operational backbone for modern content strategies enabled by AI. Expanding AI capabilities across the content lifecycle. Sanity has been releasing a range of native AI tools in recent months that are meant to assist businesses in operationalizing AI within their content workflows. The tools are meant to assist in managing large-scale content management tasks in a structured manner. One of the core innovations is the Sanity Content Agent, which can execute complex content operations directly within editorial environments. The agent is capable of analyzing thousands of pages to identify strategic gaps, audit content libraries, and prepare materials for publishing workflows. This enables content teams to maintain consistency and quality while scaling operations across large digital portfolios. Furthermore, the automation capabilities of the platform can be extended with Functions, which, together with the Agent API, enables organizations to automate translations, content distribution, as well as publishing across multiple channels. This, in turn, can help minimize operational costs while ensuring that content management is always dynamic. Furthermore, Sanity has also introduced an MCP server, which can be used for providing safe access for AI agents that operate outside of the system, allowing them access to structured content. This, in turn, can help eliminate the need for creating duplicate content repositories, as well as for custom integrations, which can be necessary for the development of AI-based applications and services. Introducing Agent Context for smarter AI interaction. Sanity's latest native AI feature, Agent Context, advances the company's broader vision for intelligent content infrastructure. Instead of relying on traditional vector-based retrieval methods, the system compresses an organization's Sanity schema so that AI agents can interpret the structure and relationships within the content model itself. With this approach, AI systems are able to translate natural language queries into precise data queries that align directly with the organization's content architecture. By maintaining the relationships and validation rules embedded in the schema, Agent Context allows AI agents to interact with content more intelligently. This structured understanding helps avoid the limitations of flattened embeddings or probabilistic vector searches that often strip away contextual relationships. As a result, AI systems can move beyond approximate retrieval toward deeper reasoning about how content elements connect across a company's digital ecosystem. "When content is modeled intentionally - with relationships, validation rules, governance, and real-time APIs - AI systems stop guessing and start reasoning," said Magnus Hillestad, co-founder and CEO of Sanity. "That's the foundation companies need to compete." Enabling the next generation of ai-driven content operations. As AI becomes increasingly integrated into marketing strategies, digital experience management, and content operations, the need for structured AI-ready content infrastructure continues to rise. As Sanity continues to develop its evolving concept of Content Operating System, it aims to help businesses meet the need for infrastructure that allows AI-ready content to be accessed and utilized effectively. This means that businesses can leverage Sanity to move beyond experimental AI operations and into fully functional AI operations with its structured content architecture, automation layers, and agent-ready contexts. For businesses looking to take advantage of the evolving AI landscape, moving into structured AI-ready content infrastructure like Sanity is one key step in making generative AI operations a tangible business reality.

Sanity launches AI Content Operating System to automate enterprise content operations at scale

Sanity has announced the evolution of its platform as the Content Operating System for the AI era, positioning itself as an intelligent backend for companies building AI content operations at scale. The platform is built around three pillars: model your business, automate everything, and power anything. Recent native AI features include Content Agent, which handles complex content operations like auditing and publishing, and Agent Context, which enables AI agents to understand structured content through schema compression rather than vector embeddings. The platform's Functions and Agent API extend automation across translation, distribution and publishing. Multimedia company Complex has automated its e-commerce editorial operations using Sanity, whilst online travel agency loveholidays replaced a £300,000-per-year translation agency. Two content specialists now manage content for over 50,000 hotels, launching new markets in days rather than months.
