About Silk Software House
Silk Software House builds and maintains business-critical backend and web systems for fintech, payments, and large-scale platforms. We value ownership, strong engineering judgment, and the ability to design solutions, not just implement tickets.

Your Role

Responsibilities
• Design and develop PHP applications from scratch
• Gather requirements and propose well-reasoned technical solutions
• Design and maintain APIs, internal services, and data exchange systems
• Design and implement CMS systems
• Create new modules and evolve existing systems

• Review code and support less experienced developers
• Collaborate with DevOps on deployment, CI/CD, and monitoring

Requirement


This role requires full-time onsite work (no remote or hybrid options). Candidates must be willing and able to work from our office near the Plac Wilsona metro station



5+ years of commercial experience as a PHP Developer
• Very good knowledge of PHP 8.1+

• Strong commercial experience with Symfony or Laravel
• Deep understanding of relational databases (MySQL/PostgreSQL)
• Strong knowledge of OOP principles, design patterns, and coding standards
• Experience with automated testing and testing concepts
• Good understanding of application security and common vulnerabilities
• Solid understanding of Git and software development workflows
• Experience working in a team using Agile methodologies
• Ability to independently gather requirements, design solutions, and justify decisions
• Effective use of AI-assisted development tools (ChatGPT, Claude, Cursor, etc.)
• English at B2+ level

Nice to Have
• Docker and containerized environments
• CI/CD pipelines (GitLab or GitHub)
• Monitoring and observability tools
• Experience in fintech or high-traffic systems
• Basic frontend knowledge (HTML, CSS, JS)

Rates (B2B)
