Principal Frontend Developer.
Wrocław/Warsaw, Poland (Hybrid)
We’re on the hunt for a Principal Frontend Developer to join our team! As our Engineering Practice continues to grow, we are looking for a Principal Frontend Consultant o help shape its future. This is a senior leadership role that sits at the intersection of technical strategy, people development, and client impact. You will work closely with our Head of Engineering to define and uphold frontend engineering standards, lead our Communities of Practice, develop the engineers around you, and act as a trusted technical partner to our clients. At the same time, you will remain hands-on — taking on Tech Lead responsibilities within client engagements when needed and leading by example in craft. This is not a purely managerial role, nor a purely technical one. It requires fluency across both and the credibility to operate at the Principal level in all three pillars of our framework: client work, internal collaboration, and technical specialism
This is a hybrid role – your time will be split between working from home and working in our Wrocław office.
To apply, please send a copy of your C.V. over to careers@testdrivensolutions.co.uk.
