About the project:
Join a fast-growing product company building an AI-powered B2B SaaS platform that helps organizations worldwide automate security, risk, and compliance workflows. The platform combines intelligent automation, real-time monitoring, and AI-driven insights to replace slow, manual processes with a continuously up-to-date, audit-ready experience. It serves startups, scale-ups, and enterprises, and is recognized by its customers and partners for both technology and a partnership-driven approach.
Role overview:
We're seeking a hands-on Full-Stack Developer to join our core R&D team and help build our cloud-based platform. You'll work across the stack, shaping the architecture, implementing new features, optimizing performance, and mentoring team members to uphold high standards. This is your opportunity to make a significant impact on a platform automating IT auditing for SaaS companies globally.
Requirements:
5+ years of backend development in Node.js (C#, Java, or C++ experience also relevant), plus solid working experience with React.
Proven production experience with microservices architecture.
Strong skills with both relational and non-relational databases, including data modeling and query optimization.
Solid experience designing, building, and integrating REST APIs.
Familiarity with AWS or a similar cloud provider.
Ability to own a module or technical project end to end and drive it independently.
Strong software design fundamentals (principles, patterns) and a self-driven approach to problem-solving.
English — Upper-Intermediate level and above, with strong verbal and written communication.
Knowledge of containerization tools (Docker, Kubernetes) is a strong advantage.
Nice to have:
Experience developing high-scale SaaS solutions.
Deep understanding of CI/CD and QA automation processes.
Maturity with AI-assisted development — able to review and understand generated code rather than relying on it blindly.
Academic background in Computer Science, Software Engineering, or a related field.
Responsibilities:
Design and build scalable backend services using microservices and containerized solutions on AWS.
Participate in architectural decisions, research, and design to deliver robust, maintainable software.
Model data and build/integrate REST APIs with third-party systems; contribute to frontend where needed.
Work directly with Product and stakeholders to shape requirements and translate them into well-scoped tasks.
Mentor teammates, promote knowledge sharing, and uphold coding standards.
Continuously improve platform performance, scalability, and maintainability while keeping up with industry trends.
What we offer:
— Flexible Work Environment: Opportunity to work remotely.
— 1:1 English Classes: Individual English language training to enhance your communication skills.
— Premium Medical Insurance: Comprehensive health insurance to ensure your well-being.
— Great Team: Work with a supportive, collaborative, and dynamic international team.
— Equipment Provided: All necessary equipment supplied for efficient job performance.
— Accounting Support: Full accounting assistance in Ukraine and Poland.
— Paid Time Off: 18 days of Annual Vacation and 7 days of Sick Leave without a doctor's note.
— Flexible payment system, which allows you to withdraw funds in one click and has about twenty withdrawal options.
Does this position sound like a perfect match? We’re eager to hear from you!
