You’ll be working on complex, real-time challenges at the core of our platform - improving latency, ensuring high availability, and making systems more efficient at scale. This is not a coordination-heavy role; it’s for someone who enjoys writing production code, solving tough engineering problems, and seeing the direct impact of their work.

If you’re product-driven, take ownership, and prefer a “build first, improve fast” approach while working on systems where every millisecond matters - this role will feel like home.

Key Responsibilities

• Work as part of a cross-functional team owning a core product within the platform
• Design, build, and deliver new backend features end-to-end in a distributed environment
• Write high-quality, production-level code daily, contributing directly to a high-load, scalable system
• Take ownership of services handling financial transactions at scale, with a strong focus on reliability and accuracy
• Proactively suggest and implement improvements in architecture, processes, and development practices
• Participate in code and architectural reviews to maintain high engineering standards

• Skilled in developing and maintaining end-to-end and unit tests
• Proven track record of developing production-ready solutions
• Degree in Computer Science or related field

Nice to Have

• Experience with large-scale microservices architecture.
• Good ground knowledge of Kubernetes
• Familiarity with cloud providers (especially AWS)
• Understanding of application security and industry best practices
• Understanding of enterprise development patterns
• Active performance observation
• Gambling domain experience

What We Offer

• Competitive Salary: We offer a competitive salary, subject to annual performance reviews
• Quarterly Bonuses: Benefit from a transparent and systematic quarterly bonus system
• Unlimited Paid Vacation: Enjoy unlimited paid vacation leave, including Ukrainian bank holidays
• Unlimited Paid Sick Leave: Take unlimited paid sick leave whenever necessary
• Flexible Schedule: We offer a flexible work schedule to accommodate your needs

PaperLink (paperlink.online) is a document sharing platform with view analytics. You send a client a document and see who opened it, which pages they read, and how long they spent on each. Plus invoicing, financial tracking, and AI integration with Claude via MCP. No competitor has MCP-based AI integration.

The product is live. We need someone who can sell it and build the revenue foundation for what comes next.

What you'll do

• Bring first paying clients from your existing network or outreach
• Build and own the sales process from scratch
• Define ICP, messaging, and channels that work
• Lay the foundation for a future sales team

Who we're looking for

Someone who has done this before. You've built revenue at an early-stage B2B SaaS. You know how to close, and you know how to build the system around closing.

Ideally you have existing contacts in the target market: freelancers, consultants, law firms, agencies, or SMBs that regularly share documents with clients.

Part-time is fine. You likely work with several projects simultaneously. That's expected.

Compensation

Commission-based with equity participation tied to MRR milestones.

Commission-based on clients you bring. Equity participation as the product grows. Salary kicks in once MRR hits a defined threshold. All terms agreed upfront.

Payments: monthly, method by agreement.

Why this might interest you

The product exists and works. Competitors charge $45-150/month. We have a free plan and a real technical advantage.

The market is large. Every freelancer, lawyer, and consultant sends documents to clients.

Early stage means real influence. You define how revenue is built here, not inherit someone else's playbook.

What not to expect

Fixed salary from day one. If you need immediate stability, this isn't the right position.

A team to manage yet. That comes later. Right now it's you and the founder.

Format

Remote. Part-time. Flexible schedule. Any time zone.
