Senior Frontend Developer

At the.good.code; we believe that the success of the project lies in clear and thorough project preparation, close collaboration with the clients, and the right team to do the job.

• Good understanding of REST APIs, data handling, and async flows, 

• Experience with testing frameworks (e.g., Jest, Cypress) and CI pipelines, 

• Fluent English and intermediate Polish in speaking and writing, 

Nice to have:  

• Experience with 3D rendering or web-based visualizations (such as product previews or interactive graphics) 

• Familiarity with backend service logic or C# (helpful when collaborating on APIs) 

• Exposure to AWS-based deployments (e.g., S3, CloudFront, Lambda) 

• Interest in UX/UI best practices and web performance optimization 

• Willingness to mentor junior developers and contribute to architectural discussions 

• Ability to think one step ahead, quickly find solutions, and identify risks or problems.  

• Eagerness to learn new tools, frameworks, and follow development trends and techniques.  

• Can-do attitude and good sense of humor.
