David Gray

Product Security Engineer — Kubernetes, Azure & secure cloud systems

Experience

Nov 2025 — Present

Led the cloud migration of 3 software toolchain applications and delivered a live demo that directly contributed to securing the company's share of a $90M contract award.
Architected and deployed cloud infrastructure with Helm charts (configuration-as-code) and infrastructure-as-code, standardizing application deployments across Azure.
Configured and operated an Istio service mesh for mutually authenticated service-to-service traffic inside Kubernetes.
Designed and threat modeled a zero-trust continuous deployment pipeline for configuration-as-code and infrastructure-as-code delivery to Kubernetes clusters, with security review built into the release process.

Jun 2021 — Nov 2025

Engineered a processor software stack from the ground up (kernel, task scheduler, communication protocols) in C and Ada for a globally distributed weapon system.
Built a Go HTTPS server for integration testing that cut testing time by 10×.
Created a portable system library for any OS or bare-metal target with C++, Docker, Bazel and GitLab CI, cutting porting work by 4×.
Applied cryptography and anti-tamper design to RTOS software, and Linux depth to cloud build pipelines.
Led the engineering effort on a cross-program missile interface application, improving real-time telemetry decoding and control (C#, WPF, XAML).
Designed, ran and analyzed requirements-based tests for a formal qualification test event, using a six-degrees-of-freedom simulation and an experimental aircraft.
Worked on the engineering behind multi-million dollar military contract wins for the weapon product lines.

Aug 2020 — May 2021

Jul 2020 — Aug 2020

Built Python preprocessing and ML pipelines (pandas, scikit-learn, matplotlib) for neuroimaging data.
Implemented dimensionality reduction, including t-SNE, and the analysis workflows around it.
Produced figures and reports with the graduate researchers for the published paper.

Jun 2020 — Aug 2020

Ran integration tests by querying cloud telemetry databases with SQL, and sped up the queries inherited from a legacy database.
Reviewed, tested and approved test cases against production software; documented bugs in Jira and Confluence.

Jan 2020 — Dec 2020

Built Flutter apps for iOS and Android on a Firebase backend for data and real-time messaging.
Owned the architecture end to end, from the data model to the screens.

Sep 2019 — May 2021

Resolved network, software and hardware issues for students, faculty and lab equipment.
Wrote documentation so the same problem did not need solving twice.
