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.

General Description

Cropwise Operations is a global leader in digital agritech solutions, operating in over 50 countries and helping optimize business processes and improve the efficiency of agronomic decision-making.

About the role

We are looking for a Presentation Designer with strong visual storytelling and structured thinking.

You will turn complex product functionality, workflows, data, and technical concepts into clear and compelling visual stories for agronomists, farm managers, customers, partners, Sales, and internal teams.

This is not a role where you simply make finished slides look better. You will need to understand a feature, ask the right questions, identify what matters to the audience, define the narrative, and then design the clearest way to explain it.

Approximately 80% of your work will be presentations and slide-based product communication. The remaining 20% will include email and social media visuals, one-pagers, and occasional event or print materials.

What you will do

Product presentations and visual storytelling — approximately 80%

• Create product presentations, feature explainers, sales and demo decks, customer-facing materials, and presentations for internal or industry events.
• Turn complex FMS workflows and technical concepts into simple narratives, diagrams, annotated product screens, infographics, and clear step-by-step explanations.
• Work from different types of source material: a content writer’s draft, product documentation, interface screens, data, rough stakeholder notes, or conversations with product experts.
• Interview Product Managers, Product Designers, agronomy experts, Sales, Support, and other stakeholders to understand how a feature works, why it matters, and which customer problem it solves.
• Define the information hierarchy and story flow before moving into visual design.
• Adapt the same product story for different audiences, contexts, and levels of technical knowledge.

• Build and improve reusable slide templates, diagram patterns, and visual systems that help the team communicate consistently and efficiently.

   

Other visual communication — approximately 20%

• Create supporting assets for email campaigns, social media, landing pages, one-pagers, and product announcements.
• Occasionally prepare event materials such as brochures, booth graphics, printed boards, and other campaign collateral.

• Use AI tools for image generation and design exploration when they improve the result. AI is welcome as a production tool; the narrative, judgment, and clarity must come from you.

   

What we are looking for

• 2+ years of experience in presentation design, visual communication, information design, and graphic design.
• A portfolio that includes presentations or visual explanations of complex products, services, processes, or data-heavy subjects.
• Strong visual storytelling skills: you can turn raw and incomplete information into a logical, audience-focused narrative.
• Strong information design skills, including hierarchy, typography, editorial layout, diagrams, flows, data visualization, and the thoughtful use of product screens.
• Curiosity and the ability to ask precise questions until you understand how something works and why it is valuable.
• Ability to work independently with incomplete inputs and propose a communication approach rather than wait for a fully prepared slide-by-slide brief.
• Advanced working knowledge of Figma and at least one presentation tool such as PowerPoint or Google Slides.
• Attention to detail and the ability to maintain brand consistency across different formats.

• English at B2+ level and fluent Ukrainian.

   

Nice to have

• Experience with B2B SaaS, enterprise, technical, or data-heavy products.
• Experience in AgTech or an interest in agricultural workflows.
• Experience with motion, short video, animation, or interactive presentations.
• Experience using AI tools for visual exploration and asset generation.

• Knowledge of print preparation and event materials.

   

This role is likely a good fit if

• You enjoy understanding complicated systems and making them feel simple.
• You care as much about the logic of a story as about the visual polish of each slide.
• You can challenge unclear content, find missing information, and propose a stronger explanation.

• You are comfortable collaborating with both creative and technical specialists.

   

How we will evaluate your application

Please include a portfolio with two or three relevant cases. For at least one case, briefly show or explain:

• what source material or problem you started with;
• who the audience was;
• how you structured and simplified the story;
• what parts of the final result you personally created.

We value the thinking behind the work as much as the visual result.

The Company Offers

• Opportunity to be a part of a best-in-class product that is used by thousands of companies around the world. 
• Annual performance bonus scheme. 
• Career growth opportunities. 
• An environment where you need to seek and implement unique solutions. 
• Training and development programs. 
• Young and dynamic team with a friendly and open culture. 
• Health and life insurance for employees and your family members. 
• 32 working days of paid annual leave and sick leave.

About Gravira Group

We’re now scaling our Affiliate direction and looking for someone who can help us build a strong pipeline of high-quality partners.

Why this role exists

Your mission is to build and convert a qualified partner pipeline, with a strong focus on Canada, Tier-1 markets and Facebook traffic.

This is a commercial acquisition role.

You’ll own the process from finding the right partner and starting the conversation to negotiating partnership conditions and bringing the partner to first traffic and first FTDs.

After the deal is negotiated, critical information is transferred to the Account/Operations Manager for documentation, tracking and reporting.

That’s what Gravity of Luck means to us.

We’re building one of the fastest-growing iGaming products in Tier-1 markets, and we’re looking for someone who enjoys bringing structure, accuracy and transparency to complex operational processes.

About Gravira Group

Gravira Group is a fast-growing international iGaming company focused on Canada and Tier-1 markets.

We build and scale our own products by combining Product, Acquisition, CRM, Payments, Engineering, Analytics and Operations into one high-performance system.

We move fast.

We make decisions based on data.

We trust ownership over bureaucracy.

As our Affiliate direction grows, we’re separating commercial acquisition from operational ownership and building a stronger operational foundation for the department.

Why this role exists

Affiliate growth creates more than new partnerships.

It creates more partner data, deal terms, payments, statuses, reports, follow-ups and dependencies between teams.

When this information is incomplete or inconsistent, small operational issues quickly become business problems.

Your mission is to make sure the operational side of Affiliate works accurately and predictably.

You’ll own partner data, reporting, documentation, follow-up control and internal affiliate processes, working closely with the Head of Affiliate, Affiliate Sales Manager, Finance, Analytics, Risk, Product and Marketing.

This is not a cold sales or partner acquisition role.

Your focus is making sure that once a partner enters the business, everything around that partnership is properly documented, tracked and visible.

What You’ll Own

• Maintaining and updating partner data in NetHunt CRM.
• Managing partner and deal information in Affilka.
• Entering, verifying and updating affiliate data after partner negotiations.
• Keeping partner statuses accurate and up to date.
• Owning daily, weekly and monthly affiliate reporting.
• Tracking payments, commissions, deal terms and follow-ups.
• Reconciling information between NetHunt, Affilka, reports and internal documentation.
• Monitoring missing information, inconsistencies and overdue actions.
• Supporting partner onboarding from the operational side.
• Controlling deadlines and preventing missed follow-ups or payment-related issues.
• Maintaining clear and reliable operational documentation.
• Identifying gaps in existing workflows and suggesting improvements.

• Improving reporting, data structures, workflows and automation where possible.

   

What Success Looks Like

Six months after joining Gravira Group:

• Partner information is accurate, complete and up to date.
• NetHunt, Affilka, reports and internal documentation remain aligned.
• Affiliate reporting is delivered consistently and without avoidable errors.
• Partner statuses, payments, commissions and deal terms are clearly tracked.
• Missing information and overdue actions are identified before they become problems.
• Partner onboarding runs through a clear and predictable operational process.
• Affiliate, Finance, Analytics, Risk, Product and Marketing teams have reliable information when they need it.
• Less time is spent searching for data, correcting inconsistencies or chasing missing information.

• Affiliate operations become more structured, transparent and scalable.

   

We’re Looking For Someone Who

• Has experience in the iGaming industry with Tier-1 products.
• Has experience in Account Management, Affiliate Operations, Partner Operations, CRM Administration, Support Operations, Data Operations or a similar role.
• Has strong attention to detail and can work accurately with structured data.
• Has experience with CRM systems, affiliate platforms, spreadsheets, reporting tools or operational databases.
• Has a strong level of Excel / Google Sheets.
• Can keep large amounts of information organized, accurate and up to date.
• Has strong follow-up discipline and doesn’t let tasks disappear.
• Has an analytical and process-driven mindset.
• Communicates clearly with both internal teams and external partners.
• Can work with repetitive operational tasks without losing accuracy or focus.
• Takes ownership of problems instead of waiting for someone else to notice them.

• Has English at B2 level or higher.

   

Nice to Have

• Hands-on experience with NetHunt.
• Hands-on experience with Affilka.
• Experience working with affiliate reporting and commission calculations.
• Experience with data reconciliation across multiple systems.
• Experience improving operational workflows or introducing automation.
• Experience working closely with Finance, Analytics, Risk, Product or Marketing teams.
• Experience in a fast-growing startup or international iGaming environment.

Why Gravira Group

This is a role for someone who likes things to make sense.

You’ll have direct influence over the structure and quality of our Affiliate operations and will work closely with teams across the business.

Your work will make partner information easier to understand, processes easier to follow and operational issues easier to catch before they become bigger problems.

We value:

Accuracy over assumptions.

Ownership over bureaucracy.

Transparency over information silos.

Process improvement over doing things the same way forever.

And people who notice when something doesn’t work — and take responsibility for making it better.

Build Gravity of Luck

At Gravira Group, luck isn’t random.

It’s the result of curiosity.

Of ownership.

Of speed.

Of hundreds of small improvements that compound over time.

If you’re the person who notices the missing field, the inconsistent number, the overdue follow-up or the broken process — and doesn’t rest until it’s fixed — you’ll feel at home here.
