Are you ready to build your career in IoT and Cloud sales

About the Company

We are a rapidly scaling e-commerce company operating in the physical goods sector, handling large volumes of financial transactions.

We are looking for a Head of Finance who will take full ownership of the company’s financial processes, systematize accounting, build a transparent cash flow management system, and ensure the financial stability of the business.

This role is for someone who does more than just monitor numbers — someone who understands the economics of a product-based business and knows how to build an effective financial system.

Key Responsibilities

• Manage the Finance Department: allocate tasks, establish procedures and regulations, and monitor their execution.
• Maintain and oversee the payment calendar.
• Plan Cash Flow and proactively identify potential cash flow gaps.
• Monitor daily cash balances across bank accounts, sole proprietor accounts, cash registers, and digital wallets.
• Ensure that accounting records match actual cash balances.
• Monitor accounts receivable and accounts payable.
• Prepare management reports, including Cash Flow, plan vs. actual analysis, and cash flow forecasts.
• Analyze expenses and optimize fees, currency conversions, and transfers.
• Negotiate with banks, payment service providers, and currency exchange services to improve financial terms.
• Systematize and automate financial processes and regular reconciliations.
• Identify financial risks and develop solutions to minimize them.
• Contribute to the development and scaling of the company’s financial infrastructure.

Requirements

We are looking for a finance professional with hands-on management experience who:

• Has at least 2 years of experience managing a Finance Department or Treasury function.
• Has experience working in product-based e-commerce.
• Has a strong understanding of cash flows in a product-based business: procurement → inventory → sales → delivery → cash on delivery.
• Is experienced in working with payment calendars and Cash Flow management.
• Understands key metrics such as inventory turnover and tied-up capital.
• Is highly detail-oriented and comfortable working with large volumes of financial data.
• Has strong negotiation skills.
• Is able to make independent decisions and take full ownership of results.

Professional Skills

Advanced Excel / Google Sheets skills:

• Pivot tables
• Data analysis
• Financial modeling

Experience working with the following will be important:

• 1C / BAS
• Online banking platforms
• Payment service providers
• Crypto wallets
• Financial management and accounting systems

A strong advantage: experience building and automating financial accounting and reporting processes from scratch.

What We Offer

• Kyiv, hybrid work format
• Autonomy in decision-making within your area of responsibility
• An opportunity to directly influence financial processes and the company’s development
• Paid vacation and sick leave
• Management support for implementing new solutions and initiatives

We look forward to hearing from you! We’ll be happy to get to know you.

Our client is building a digital twin engine that simulates enterprise IT environments (cloud, SaaS, identity, endpoints, networks, security products) with high fidelity, then runs attacks from agentic red teams against them to capture realistic telemetry for AI security training and evaluation.

This is a zero-to-one build — you'll define the architecture and technical direction from scratch.
 

Who we're looking for

A hybrid of offensive security expert and production software engineer — someone who thinks like an attacker and can turn that into a reliable, scalable system. Not a pure pentester, not a pure backend engineer.
 

Scope of Work

• Own the architecture and hands-on development of the digital twin engine.
• Build high-fidelity simulations of company stacks — users, networks, cloud, SaaS, identity, endpoints, security products.
• Run attacks from agentic red teams and capture realistic telemetry.
• Adapt environments to customer stacks while protecting privacy, isolation, and authorization boundaries.
• Lead the technical roadmap and engineering standards across contributors.
• Keep the engine reproducible, reliable, scalable, and easy to extend.
   

Requirements

• Deep offensive/defensive security knowledge, including how security products (EDR/XDR/SIEM) work internally.
• Cloud security experience (AWS/Azure/GCP) and familiarity with anti-forensics techniques.
• Ability to judge whether a scenario and its telemetry are realistic, too easy, or ambiguous.
• Strong software engineering skills — proven experience shipping and operating production systems.
• Experience building cyber ranges, digital twins, security labs, or large-scale simulated environments.
• Strong knowledge of security telemetry and data pipelines (cloud, SaaS, identity, endpoints, networks).
• Comfortable leading ambiguous, zero-to-one development under uncertainty.
• Strong project planning, technical coordination, and code review skills.
   

Nice to have: AI agents/evals experience (guardrails, reproducibility, human review); conference talks or CTF/red team community involvement; background at BAS companies (Pentera, SafeBreach, Cymulate) or cyber range platforms (CybExer, SimSpace).
