About the Role

Anduril's Multi-National Digital Infrastructure (MDI) team builds and sustains the sovereign cloud, classified networks, edge compute, and coalition interoperability layer that Anduril's products depend on across nations and classification levels. The Principal Systems Engineer is MDI's chief engineer, owning the technical vision, architectural coherence, and engineering standard for this infrastructure globally. This role involves hands-on building and shipping, setting standards by doing the work and codifying patterns for scalability.

Responsibilities

Own the MDI technical architecture end-to-end, including sovereign cloud (IL5/IL6), classified bilateral networks, maritime C2 patterns, edge-to-cloud pipelines, and coalition interoperability.
Ensure decisions in one workstream do not create debt in another, maintaining a full picture across concurrent milestones.
Make key architectural decisions, including technology selection, accreditation-driven design constraints, build vs. buy, and divergence from common baselines.
Drive the 'build once, deploy per nation' model with common baseline infrastructure and intentional, late divergence.
Define and enforce engineering standards, including IaC practices, security baselines, deployment patterns, documentation requirements, and peer review processes.
Establish RFC-governed decision processes for deliberate, recorded, and reviewable architectural choices.
Own reliability and quality improvement, setting measurable targets and driving the team towards them.
Translate national accreditation requirements (DCSA, IRAP/ISM, NCSC) into engineering work.
Build common infrastructure patterns to enable MDI expansion to new nations and classification levels without proportional engineering effort.
Ensure subsequent national deployments are faster than the previous ones through configuration over engineering.
Own the module library, deployment templates, and accreditation frameworks.
Prevent the development of bespoke/incompatible patterns that hinder scalability.
Serve as the technical leader for MDI's distributed engineering team across the US, UK, and AUS.
Set direction, mentor engineers, review work, and raise the engineering bar.
Define the technical hiring bar and skills framework for MDI engineering roles.
Establish effective cross-timezone collaboration patterns.
Represent MDI's technical capabilities and constraints to leadership.
Shape technical possibilities by translating engineering reality into program decisions.
Interface with adjacent technical teams on shared concerns.

Requirements

Deep experience designing and building classified network infrastructure across multiple nations or accreditation frameworks.
Hands-on experience with sovereign cloud architecture, including implementation (IaC, module development, deployment automation).
Experience with COMSEC integration, HAIPE/KG-175X, and the intersection of network sovereignty and cryptographic key management.
Demonstrated ability to set engineering standards for a distributed team and drive adoption without micromanagement.
Track record of building scalable, reusable infrastructure patterns.
Understanding of multinational compliance and accreditation (at least 2 of: DCSA/NIST 800-53, IRAP/ISM, NCSC Cyber Essentials+/OFFICIAL-SENSITIVE).
Experience operating as the architectural decision-maker.
Ability to manage both tactical delivery and strategic architecture simultaneously.
Experience in the AUKUS or Five Eyes defense industrial context (preferred).
Familiarity with bilateral/multilateral classified data sharing mechanisms (preferred).
Background in both network engineering and cloud infrastructure (preferred).
Experience with defense accreditation processes from the engineering side (preferred).
Prior experience working with or within allied Defence organizations (preferred).
