• Collaborate with cross-functional teams to deliver secure and usable platform capabilities, and support integrations with customers’ on-premises and cloud environments.
• Mentor engineers and contribute to a culture of technical excellence, ownership, and continuous learning, while influencing architecture beyond your immediate area.
• Strong professional experience building and operating production backend services and improving their reliability, performance, and maintainability.
• Sound judgment when working with sensitive data, trust boundaries, authorization decisions, and security-sensitive failure modes
• Load testing, performance analysis, capacity modeling, and scaling strategy
• Integrating SaaS or cloud services with customer-managed on-premises infrastructure, private clouds, public clouds, and enterprise security products
• Kubernetes, cloud infrastructure, infrastructure as code, or platform engineering

Requirements

• Fluency in Go, Java, C++ or Python; willingness to work primarily in Go
• Strong testing practices, including unit, integration, contract, load, and failure-mode testing as appropriate
• Experience with relational or distributed data stores, asynchronous processing, and service integration patterns
• Deep understanding of distributed-systems principles, including consistency, concurrency, fault tolerance, networking, and service-to-service communication
• This position requires access to export controlled information.

Experience designing and implementing RESTful and/or gRPC APIs

• Ability to communicate technical decisions clearly in design documents, reviews, and cross-functional discussions
• The ideal candidate combines strong software-engineering fundamentals with sound judgment around reliability, security boundaries, failure modes, and operational trade-offs
• Experience in one or more of the following areas is helpful but not required:
• SRE and reliability practices, including incident response, error budgets, capacity planning, and operational readiness
• Building security products for enterprise, regulated, or otherwise security-sensitive customers

SCIM, enterprise identity integrations, SSO, or lifecycle management

• Designing or building authorization systems at scale, including policy evaluation, permissions, tenant isolation, or least-privilege access
• Service observability using metrics, structured logging, distributed tracing, and production diagnostics
