Lead the design and implementation of Aalyria’s security platform, including identity, authentication, authorization, PKI, workload identity, secrets, key management, audit evidence, and security standards. Build systems that operate securely in commercial, government, classified, and disconnected environments. Set technical direction across teams, mentor engineers, threat-model distributed systems, and operate production services through upgrades, maintenance, and incidents.

Build and operate Spacetime’s security platform, including authentication, authorization, PKI, workload identity, secrets and key access, SDKs, audit logging, and threat mitigations. Develop secure capabilities for commercial, government, classified, and disconnected environments. Collaborate with product and infrastructure teams, support production operations, participate in on-call and incident response, and maintain hardened supply-chain and deployment controls.

Build scalable simulation and planning systems for complex communications networks. Model hypothetical scenarios, allow users to vary configurations and assumptions, evaluate impacts, compare tradeoffs, identify risks, and integrate simulation capabilities into broader product workflows. The role involves full-stack engineering across design, development, testing, and operations, with emphasis on distributed systems, algorithms, network modeling, and computational reliability.

Conduct applied research on scalable optimization and resource-allocation algorithms for large communication networks. Apply machine learning, reinforcement learning, integer optimization, graph-based methods, and metaheuristics to improve solution quality and efficiency. Collaborate with software engineers to integrate algorithms into production aerospace networking systems, evaluate performance at realistic scale, publish research, support patent applications, and document novel methods.

Design and develop backend distributed systems for 5G non-terrestrial networks, Direct-to-Cell services, satellite orchestration, and terrestrial network coordination. Build scalable cloud-native software using C++, Golang, Java, gRPC, Protocol Buffers, and Kubernetes. Translate 3GPP and O-RAN specifications into reliable software, integrate platform components, document implementations, troubleshoot issues, and collaborate with telecom solution architects.

Design and evolve core data models and durable APIs for complex communications networks. Build, test, operate, and maintain production-grade interfaces and abstractions for heterogeneous physical and logical networks while ensuring compatibility, consistency, quality, and performance. Manage project priorities, timelines, and deliverables within the Spacetime engineering team.
