Senior Fullstack Developer

This is a remote position.
We are lookingfor a Senior Full StackEngineer to join ourengineering team. Thisis more thana hands-ondevelopment role. We'relooking for someonewho will elevatethe team's engineeringpractices, mentor fellowengineers, drive technicalexcellence, and leadby example inbuilding reliable, scalable, and maintainable software.
You'll work ona mission-criticalenterprise platform responsiblefor managing thecomplete lifecycle ofproduct pricing across 100+ global markets .

We follow atrunk-based developmentmodel with automatedCI/CD pipelinesusing GitHub Actions , ArgoCD , and progressive environmentpromotion from Developmentthrough Production.
Success in thisrole goes wellbeyond delivering features. You'll help shapethe team's engineeringculture by improvingcode review quality, defining architecturalpatterns, reducing technicaldebt, strengthening testingand observability practices, and helping engineersgrow through coaching, technical discussions,and mentorship. We'relooking for someonewho raises thebar for theentire team—aforce multiplier ratherthan an individualcontributor.
