Вакансія: Component 1 Lead – Cybersecurity Enabling Environment Lead for U.S. Cybersecurity for Critical Infrastructure in Ukraine (CCI) Activity

BACKGROUND:

The U.S. Cybersecurity for Critical Infrastructure in Ukraine (CCI) Activity began in May 2020. The purpose of the CCI Activity is to reduce, and ultimately eliminate, cybersecurity vulnerabilities in Ukraine’s critical infrastructure sectors. In the same way that cyberattacks drove Estonia to innovate cybersecurity practices, systems, and entrepreneurship as the backbone of its digital transformation. 

The CCI Activity continues to improve the cyber-resilience of Ukraine and its critical infrastructure sectors through three interlinked, mutually reinforcing objective areas that address legal, policy, institutional, workforce, and market gaps to strengthen long-term national resilience.

Building on progress achieved from 2020 to 2026, and under the Department of State, the Activity will continue implementation of these objectives while aligning them with U.S. foreign-policy priorities for trusted technology, supply-chain security, and transatlantic digital integration.

Objective 1: Create a safe, trusted environment to accelerate the development of people, processes, and technology to support cybersecurity across CI sectors and assets in Ukraine.

Objective 2: Strengthen Ukraine as a sovereign nation built on a secure, protected, and dynamic economy, supported by a talented pool of human capital.

Objective 3: Stimulate demand for and supply of Ukrainian cybersecurity solutions and service providers to empower, equip, and finance cybersecurity entrepreneurs and businesses

The CCI Activity consists of three complementary, mutually reinforcing, and integrated components:

Component 1: Strengthen the Cybersecurity Enabling Environment

This component enhances Ukraine’s ability to protect and modernize its civilian digital infrastructure by embedding U.S. and allied cybersecurity standards into the governance, architecture, and operational systems of critical infrastructure (CI). It prioritizes the divestment of high-risk digital assets and the adoption of secure-by-design technologies that advance trusted supply chains, secure communications, and resilient public services in line with U.S. strategic and commercial interests.

Component 2: Develop Ukraine’s Cybersecurity Workforce

This component builds the institutional and technical foundation for a civilian cyber workforce capable of securing Ukraine’s critical infrastructure during wartime and sustaining digital resilience throughout long-term recovery. It anchors that workforce in U.S.-backed standards, trusted technology principles, and interoperable training models aligned with allied strategic frameworks. All workforce development activities under this component shall be focused on applied operational capability and demonstrable use of skills, rather than academic, theoretical, or strategy-only training outcomes.

Component 3: Build a Resilient Cybersecurity Industry

This component strengthens Ukraine’s domestic cybersecurity and dual-use technology sector as a frontline contributor to national resilience and a trusted partner in U.S. and allied digital ecosystems. It aims to reduce Ukraine’s reliance on high-risk and adversary-origin platforms, and position select Ukrainian firms as interoperable contributors within U.S. and allied technology supply chains where this serves U.S. strategic, security, and commercial interests.

JOB DESCRIPTION:

Under the leadership of the Cybersecurity Enabling Environment Lead, Component 1 will enhance Ukraine’s ability to protect and modernize its civilian digital infrastructure by embedding U.S. and allied cybersecurity standards into the governance, architecture, and operational systems of critical infrastructure (CI). It will prioritize the divestment from high-risk digital assets and the adoption of secure-by-design technologies that advance trusted supply chains, secure communications, and resilient public services, in line with U.S. strategic and commercial interests. Implementation under this component shall prioritize verifiable operational change on live systems and exclude advisory, planning, or roadmap-only outputs that do not result in deployed or enforced outcomes. 

Component 1 will support designated Ukrainian institutions —primarily the Ministry of Digital Transformation (MDT), National Cybersecurity Coordination Center (NCSCC), National Security and Defense Council (NSDC), and other authorized agencies— in implementing defined, outcome-oriented civilian cyber governance actions.  Such support shall focus on the execution of approved institutional changes, the enforcement of coordination protocols, and the operational application of national cyber incident management procedures, rather than on the production of advisory or conceptual guidance. 

To strengthen national preparedness, Component 1 will provide continuous support to critical infrastructure cyber posture assessment and remediation activities, including penetration testing and follow-on remediation tied to identified vulnerabilities, consistent with Ukraine’s national cyber incident management framework. These activities shall focus on improving real-world defensive readiness rather than exercise-based simulation.

START HERE

Most of what we need is ordinary platform work. One part is not.

We run a multi-tenant SaaS platform on Kubernetes with a MongoDB data tier, and we are designing it for its enterprise stage. The hardest problem in the engagement is reshaping stateful workloads in production without losing data, and designing tenant isolation so that one customer's load cannot degrade another's.

If reshaping a StatefulSet's storage in a live cluster is a problem you have actually solved rather than read about, keep reading. If it is not, the rest of this list will look familiar and you will probably be bored.

WHAT YOU WILL OWN

The data tier. Design and implement high availability for MongoDB: replication topology, migration paths that are reversible at every step, and backup and restore that is verified rather than assumed.

Tenant isolation. Design multi-tenant resource isolation so workloads stay predictable as customer count and data volume grow. Noisy-neighbor behavior is the failure mode we care about most.

Release integrity. Mature the deployment pipeline so releases are deterministic and auditable, and so what is running matches what was declared.

Observability that means something. Define the service-level indicators that reflect real customer experience, and build the measurement behind them. We are not looking for more dashboards.

Async and background processing. Architect the model for long-running, data-heavy operations.

Capacity. Right-size resources against measured usage, introduce autoscaling, and load test at realistic data volumes.

Cloud strategy. Give us your long-term view. We are on Azure and are not planning to migrate, but we want an architect's assessment to plan against.

WHAT WE NEED TO SEE

You have done stateful surgery in production. Reshaping storage, promoting a standalone database to a replicated one, or migrating a data tier with a rollback path at each step. This is the one thing we cannot backstop with review.

You have solved tenant isolation for real. Not "we used namespaces." You have hit a noisy-neighbor problem, diagnosed it, and have opinions about which mitigations actually held.

You debug by measurement. You instrument and observe rather than reason from intuition, and you have been wrong about a bottleneck before and can say so.

You can read Node.js well enough to reason about where memory and time go. You do not need to write it.

You will disagree with a proposed design and explain why. You will be the most experienced infrastructure person here, and deference would waste the engagement.

5+ years in platform engineering, SRE or cloud architecture, with real design ownership on at least one production system.

English sufficient for written technical discussion and calls.

THE STACK, FOR MATCHING

Kubernetes and Helm in production, MongoDB, Azure and AKS preferred (equivalent AWS or GCP depth is fine), Terraform, Prometheus, Grafana, Alertmanager, Loki, Node.js services.

Nice to have: GitOps (Argo CD or Flux), k6 or JMeter, exposure to blockchain infrastructure or carbon markets. The domain is genuinely optional, we will teach it.

HOW TO APPLY

Send your CV and answer one question. It matters more to us than the CV does.

Describe a time you changed the shape of a stateful workload in production. A storage migration, a topology change, a database promotion, anything where the data had to survive. What was your rollback at each step, and what did you check before you started?

Answers that describe the happy path tell us less than answers that describe what almost went wrong. We are not looking for a keyword list.
