Full-Stack Solutions Architect w Warząchewka Polska, Polska

About the role

Join us in shaping the technology backbone of our enterprise platforms, where front-end applications, APIs, data, and cloud infrastructure come together to power business-critical systems. As our Full-Stack Solutions Architect, you'll define target-state architecture, guide modernization efforts, and stay hands-on enough to validate designs, review implementation, and resolve complex production issues. If you love connecting business strategy to real technical execution across the full stack, we want to hear from you.

What you'll do

• Own solution architecture across UI, backend services, APIs/integrations, databases, cloud infrastructure, and security, translating business needs into current-state, transition-state, and target-state designs
• Design and guide modernization of full-stack applications built on PHP (7/8) with MVC or singleton frameworks, and https://jobeax.com/link/tzGekrj9a8ToGEDv (2 or 3) on the front end
• Architect and develop RESTful APIs following OpenAPI standards, defining integration, authentication, versioning, and error-handling practices
• Design data and caching strategies using MongoDB and Redis, including schema design, performance, replication, and backup/restore
• Design and deploy secure, scalable AWS architectures using EC2 and ECS, with sound networking and IAM practices, containerized via Docker
• Establish observability, high-availability, and disaster-recovery patterns, and lead investigations into performance, security, and integration issues
• Mentor engineers, lead design reviews, and communicate architectural decisions clearly to both technical and executive stakeholders

What you bring

• Strong experience in software/platform engineering, including leadership in solution or enterprise architecture
• Strong hands-on experience with PHP 7/8 using an MVC or singleton framework, plus a modern JavaScript framework - https://jobeax.com/link/tzGekrj9a8ToGEDv 2 or 3 required
• Proven experience building and integrating RESTful APIs to OpenAPI standards
• Practical experience with MongoDB and Redis, including performance, replication, and data integrity considerations
• Core AWS knowledge (EC2, ECS), networking for application deployment, IAM, and Docker/container platforms
• Ability to produce clear architecture documentation and explain trade-offs, risks, and decisions to technical and nontechnical audiences alike
• Proven judgment balancing strategic architecture with incremental delivery, legacy constraints, and operational realities

Nice to have

• Agentic AI experience
• Architecture or cloud certifications (TOGAF, AWS Solutions Architect, or equivalent)
• Experience modernizing monolithic platforms into modular, API-led, containerized, or cloud-native systems
• Performance testing/capacity engineering experience (e.g., JMeter)
• Application security or penetration testing exposure (e.g., Burp Suite)
