About this role.
EMPLOYER IS A CONTRACTOR FOR THE U.S. GOVERNMENT. THIS POSITION REQUIRES U.S. CITIZENSHIP.
Role Description
We are seeking a talented and experienced Platform Engineer to join our team. Possessing strong proficiency with Kubernetes, the ideal candidate will play a crucial role in the development and maintenance of our platform, demonstrating a strong understanding of system architecture, problem-solving skills, and the ability to guide junior engineers.
As a Platform Engineer within our organization, you will join a team of dedicated unicorns who are focused on advancing freedom and independence globally. Our teams work on various different technical baselines depending on specific engagements. We focus our Products on the Platform layer, but to deliver for our Heroes, we also work IaC automation, security, and implementation.
Responsibilities
You will help us automate and build a runtime Production Environment and serve as a link between the Applications, either custom development, COTS, or OSS, and that environment, advocating best practices and facilitating communication between the application teams and platform teams.
In this position, you will be expected to:
- Validate Solutions/Implementations: Ensure that solutions and implementations align with the outlined tasks and business requirements. Conduct thorough validations to maintain the integrity and efficiency of the platform.
- Independently Problem Solve: Demonstrate the ability to identify and solve business problems independently. Develop small components to address specific challenges without relying on explicit architecture diagrams.
- Understand Medium-Level Tasking: Comprehend how medium-level tasks contribute to the achievement of overall goals. Collaborate with cross-functional teams to integrate various components into a cohesive and functional platform.
- Estimate Time and Effort: Provide accurate time and effort estimates for medium-sized tasks. Assist in project planning and resource allocation based on estimated timelines.
- Demonstrate Programming Language Proficiency: Possess familiarity with at least one programming language. Exhibit a basic understanding of when to use a programming language versus a shell for efficient task execution.
- Own the Bridge Between Application Development and Production: Own the bridge between the Application Development team(s) and the Production Environment.
The listed responsibilities are not exhaustive and additional responsibilities may be assigned based on the evolving needs of the organization. We are seeking a dynamic individual who is able to adapt and take on new responsibilities as they arise.
Clearance & Travel Requirements
- Clearance Requirement: Active Secret clearance highly preferred.

Sample interview questions
I would establish standardized namespaces, RBAC policies, network policies, workload templates, image provenance controls, and admission policies. I would provide reusable deployment patterns through Helm or Kustomize, integrate secrets management, and embed security scanning into CI/CD pipelines. Platform observability and clear self-service documentation would help teams deploy safely without creating unnecessary operational bottlenecks.
I use shell scripting for short, linear operating-system or command-line tasks with limited error handling and data complexity. For reusable automation, API integrations, structured data processing, testing, concurrency, or more sophisticated error handling, I prefer a language such as Python or Go. The decision is based on maintainability, reliability, security, and the expected lifecycle of the automation.
I would first assess impact and recent changes, then inspect deployment status, pod events, logs, container exit codes, resource limits, readiness and liveness probes, and service endpoints. I would validate configuration, secrets, image versions, network policies, and dependent services, using metrics and traces to narrow the failure domain. If necessary, I would roll back through the approved deployment process and document the root cause and preventive actions.
I integrate security early through code scanning, dependency and container-image scanning, infrastructure-as-code policy checks, signed artifacts, secrets detection, and automated compliance gates. I also ensure that deployment identities follow least privilege and that runtime controls, logging, and monitoring are in place. Security findings should be actionable and calibrated to avoid creating excessive noise for engineering teams.
I would clarify the desired outcome, identify assumptions and dependencies, inspect the existing environment, and break the work into discovery, implementation, validation, documentation, and rollout activities. I would estimate each component, include reasonable risk and integration contingency, and clearly communicate confidence level and blockers. As discovery resolves uncertainty, I would update the estimate and keep stakeholders informed.
