• Improve platform security through strong access controls, auditability, secrets management, tenant isolation, and secure service-to-service communication
• Build background-agent systems that automate support and operational workflows while maintaining clear safety controls and human oversight
• Develop integrations with collaboration, ticketing, source-control, and internal operational tools
• Create safe AI-agent execution patterns, including isolated runtimes, scoped permissions, tool allowlists, approval workflows, and output-safety checks
• Improve reliability and operability through monitoring, tracing, incident response, testing, and performance engineering
• Partner with product, security, infrastructure, and support teams to turn complex requirements into scalable platform capabilities
• Mentor engineers, contribute to technical standards, and lead design discussions across teams
• Lead complex projects, make strong architectural decisions, and improve the systems around them
• Set technical direction for broader areas, align teams around platform investments, and create leverage through mentorship, standards, and architecture
• Our work includes:
• Go, TypeScript, and Node.js
• RESTful APIs and distributed services
• PostgreSQL, MongoDB, and event-driven systems
• Workflow orchestration and asynchronous job processing
• Docker, Kubernetes, cloud infrastructure, and CI/CD
• OAuth 2.0, OIDC, SAML, JWTs, MFA, RBAC, API scopes, and service authentication
• Observability tooling, including metrics, logs, tracing, and alerting
