Company mission
To enable faster, smarter decisions, by syncing data across all products in real-time.
Role
Who you are
- 8+ years of experience as a Software Engineer
- Recent experience driving technical impact across teams and time horizons
- A record of leading multi-quarter initiatives and evolving system architecture
- Strong architectural judgment with a tight link to product and business outcomes
- Thoughtful, high-context communication thats driven by a desire for clarity, not control
- A pattern of multiplying others: through systems, standards, and mentorship
- The ability to move fast with judgment while knowing when to ship, and when to reshape
- Core tech we use
- Frontend: React, TypeScript, Vite, shared component libraries, client-side observability
- Backend: Node.js, PostgreSQL, Redis, secure RESTful APIs, distributed identity and access services
- Authentication & Authorization: Keycloak, OpenID Connect (OIDC), SAML 2.0, OAuth 2.0, Attribute-Based Access Control (ABAC), JSON Web Tokens (JWT), role and policy-based access frameworks, federated identity provider integrations (e.g., Okta, Active Directory, Keycloak, etc…)
- Infrastructure: Kubernetes, AWS, Terraform, CI/CD pipelines, container security and secrets management
- Integrations: CSV/Excel/KML importers, PDF exports, DoD and enterprise data systems, secure API gateways, and auditing pipelines
What the job involves
- We’re hiring a Staff Software Engineer to design, build, and operate the authentication and identity systems that power our platform
- This is a hands-on engineering role with a focus on reliability, scalability, and secure user experience
- Our authentication stack is built on modern technologies including Keycloak, OIDC/SAML/LDAP integrations, and cloud-native infrastructure
- We value strong problem-solving skills, sound engineering judgment, and a deep understanding of distributed systems and security principles
- You’ll work on high-impact systems including (but not limited to) identity provider integrations, access control frameworks, token management, and policy enforcement infrastructure
- Expect to tackle challenges in federated identity, Attribute-Based Access Control (ABAC), multi-tenant authorization, session management, and fault-tolerant authentication flows
- You’ll play a key role in shaping our authentication architecture and defining the long-term strategy for identity and access management across the platform
- If you enjoy thinking deeply about security trade-offs, scaling authentication systems, and building reliable identity foundations that balance usability with robust access control, you’ll thrive here
- Design, build, and maintain authentication and identity services that power mission-critical platform access and authorization
- Integrate and extend Keycloak to support complex identity provider (IdP) integrations, single sign-on (SSO), and federated authentication
- Implement and evolve Attribute-Based Access Control (ABAC) frameworks to enable fine-grained, policy-driven authorization across systems
- Work across the stack — from APIs and access tokens to infrastructure automation, deployment, and observability of authentication workflows
- Diagnose and resolve reliability, latency, and scalability issues in production authentication and authorization flows
- Collaborate on architecture and long-term strategy for secure, resilient, and high-availability identity systems
- Implement and refine monitoring, auditing, and alerting for authentication and access events to ensure security visibility and compliance
- Balance security, user experience, and delivery velocity, ensuring pragmatic decisions that maintain both product agility and engineering quality
