• Build platform services that support configurable rules, workflow logic, auditability, and secure operational history.
• Develop and maintain data schemas, domain models, event structures, persistence strategies, and data access patterns across backend systems.
• Contribute to shared data exchange capabilities, including controlled data sharing workflows and cross environment integration patterns.
• Design service to service communication patterns, API contracts, event flows, and integration points between distributed services.
• Build backend infrastructure for authentication, authorization, role based access control, and customer onboarding workflows.
• Build event driven systems using Apache Kafka or comparable messaging technologies.
• Partner with product, frontend, AI/ML, DevOps, and security stakeholders to translate requirements into well structured backend services.
• Improve system performance, scalability, reliability, and debuggability across production services.
• Participate in design reviews, code reviews, implementation planning, and security reviews.

• 5+ years of professional backend or systems engineering experience.
• Strong proficiency in Go, C++, Java, Rust, or a similar object oriented or lower level programming language.
• Experience designing and operating cloud based architectures on AWS, Azure, GCP, or similar cloud platforms.
• Strong understanding of microservice architecture, service boundaries, API design, inter service communication, and distributed systems tradeoffs.
• Experience with data modeling, schema design, relational and/or non relational databases, and long term data maintainability.
• Experience with Apache Kafka, event driven architectures, message queues, or stream processing systems.
• Experience designing authentication and authorization systems, including role based access control.
• Experience building secure backend services that support structured data exchange, schema driven integrations, or controlled data sharing workflows.
• Strong debugging and performance analysis skills in production backend systems.

• Experience building rules engines, policy engines, workflow engines, audit services, or queryable event history systems.
• Experience with schema registries, protobuf, Avro, JSON Schema, OpenTelemetry, PostgreSQL, OpenSearch, Elasticsearch, or similar technologies.
• Experience building backend systems for real time collaboration, simulation, spatial platforms, command and control systems, or operational decision support tools.
• Experience with Kubernetes, Docker, infrastructure as code, CI/CD, and modern DevOps practices.
• Familiarity with secure software development practices, audit logging, secrets management, and least privilege access design.
• Experience working in regulated, government, defense, or enterprise security environments.
• Experience working with computer vision, natural language processing, or AI/ML teams.
