Clear Fracture is inventing a new class of AI-driven data integration platforms, enabling organizations to securely connect and operationalize data across complex environments. Our platform uses multi-agent systems to automate data integration, analysis, and operational workflows for mission-critical government and enterprise applications.

We are seeking a backend focused Senior Software Engineer to design and build the authorization and identity systems embedded directly within our product. This is a hands-on engineering role focused on implementing fine-grained access control, authentication flows, and tenant-aware security mechanisms across our platform. You won't just be managing an identity provider; you’ll be designing and coding the high-performance authorization middleware and SDKs that allow autonomous agents to navigate sensitive data pipelines securely. If you enjoy solving complex distributed systems problems where 'standard' cloud-based solutions don't work, this is your role.

You will work closely with backend, platform, and DevOps engineers to integrate authorization into core application workflows, APIs, and agent systems. This role is ideal for engineers who enjoy building security-critical systems in production code, not just configuring or operating infrastructure.

Note: This is not a DevOps or infrastructure security role. It focuses on building application-layer authorization and identity systems.

Key Responsibilities

Authorization Systems: Design and implement fine-grained authorization systems within the product, including role-based and policy-based access control models for users, organizations, APIs, and agent workflows.

Application Integration: Write production-level backend code to enforce authorization across APIs, services, and agent execution paths. Partner with other engineers to embed access control directly into core product functionality.

Identity & Authentication: Implement authentication flows and integrate with enterprise identity providers (OAuth2, OIDC, SAML, Active Directory), ensuring seamless and secure user and service authentication.

Multi-Tenant Design: Design and enforce tenant-aware access control and isolation across application services, data layers, and compute workloads.

Security Architecture (Application Layer): Contribute to the design of authorization and identity architecture, including policy models, enforcement patterns, and system boundaries

Secure System Design: Participate in threat modeling and design reviews, with a focus on authorization boundaries, privilege escalation risks, and least-privilege enforcement.

Agentic Security: Defining and monitoring operational constraints to mitigate the risk of prompt injection or goal-misalignment.

Distributed Systems Integration: Design authorization approaches that function reliably across distributed systems, including cloud-connected and air-gapped environments.

Developer Experience: Create clear abstractions, APIs, and documentation that make it easy for other engineers to correctly implement and extend authorization logic.
