Principal Software Engineer, InfraEng Platform Team

Anduril • Costa Mesa, CA

5h

About The Position

The InfraEng Platform Team owns the central hub for all of Anduril's infrastructure, including the console, CLI, and API that the rest of the company uses to consume infrastructure. This role involves evaluating the existing codebase, setting technical direction, and designing and building the core APIs, services, and data models that expose infrastructure as self-service across AWS, Azure, and on-prem. The team defines and champions shared patterns for identity, authorization, auditing, and ergonomics, aiming to replace tickets with safe, bounded self-service across every team and provider. This is a hands-on role requiring deep dives into networking, systems, and cloud as needed.

Requirements

• 10+ years of software engineering experience, including building and operating platform or infrastructure software at scale.
• Strong proficiency in Go, Python, or Java, or equivalent languages suited to systems and platform work.
• Deep understanding of control plane and data plane design: desired state, reconciliation, failure isolation, and blast radius.
• Strong hands-on AWS or equivalent major cloud providers, experience across compute, networking, IAM, storage, and managed Kubernetes.
• Strong grounding in containers and ephemeral compute, such as Docker, Kubernetes, and immutable infrastructure patterns, or equivalent.
• Experience shipping both backend services and user-facing surfaces (console, CLI, or API) for large and varied user bases.
• A track record of designing CI/CD pipelines and branching and release strategies that keep deployments safe with many contributors.
• Depth below the application layer in networking, systems, or cloud, and the willingness to learn the others.
• High ownership and operational excellence. You run what you build, measure it, and fix root causes.
• Proven ability to influence senior stakeholders and peer teams without authority.
• Must be eligible to obtain and maintain a US Secret Security clearance.

Nice To Haves

• Experience building or integrating with identity and authorization systems, such as OIDC, SAML, OPA, Cedar, or equivalent.
• Experience implementing RBAC or ABAC models within a product or system.
• Experience with Azure, on-prem, or equivalent environments, including abstractions that work across providers.
• Experience with Kubernetes controllers or operators, Crossplane, or equivalent infrastructure abstraction frameworks.
• Infrastructure as code at scale with Terraform, OpenTofu, or equivalent tools.
• Familiarity with enterprise networking or backbone infrastructure and how platforms expose it to users.
• Experience in regulated environments such as FedRAMP, DoD IL levels, CMMC, or equivalent.
• Front-end experience with TypeScript and React, or equivalent, for console development.

Responsibilities

• Evaluate the existing codebase and set technical direction: keep, extend, or rebuild.
• Design and build the hub’s core: the APIs, services, and data models that expose infrastructure as self-service across AWS, Azure, and on-prem.
• Decide where control planes and data planes separate, where they nest, and where they should not.
• Document the reasoning so others can extend it.
• Define the contracts and patterns partner teams use to plug into the hub, then help them adopt those patterns.
• Build a single identity and authorization layer (RBAC and ABAC) with a complete audit trail for every action the platform exposes.
• Ship backend services and the console, CLI, and API surfaces users touch.
• Turn common infrastructure requests into bounded self-service actions that take tickets off the critical path.
• Establish the CI/CD pipelines, source control practices, and deployment safety controls for a codebase with many contributors.
• Own what you build in production, including observability, on-call, incident response, and postmortems.
• Partner with connectivity, backbone, cloud, and product teams on shared interfaces.
• Influence their roadmaps without direct authority.
• Mentor the engineers who join the team after you.

Benefits

• Highly competitive equity grants are included in the majority of full time offers; and are considered part of Anduril's total compensation package.
• Top-tier benefits for full-time employees, including a comprehensive, competitive benefits package (available at little to no cost to employees) ensures you’re supported in health, recovery, and whatever comes next.
