Qodea • Romania
Posted: January 29, 2026
Job Description
Work where work matters.
We are a global technology group built for what's next, offering high calibre professionals the platform for high stakes work, the kind of work that defines an entire career. When you join us, you're not just taking on projects, you're solving problems that don't even have answers yet.
You will join an exclusive roster of talent that global leaders, including Google, Snap, Diageo, PayPal, and Jaguar Land Rover call when deadlines seem impossible, when others have already tried and failed, and when the solution absolutely has to work.
Forget routine consultancy. You will operate where technology, design, and human behaviour meet to deliver tangible outcomes, fast. This is work that leaves a mark, work you’ll be proud to tell your friends about.
We look for people who embody:
Innovation to solve the hardest problems.
Accountability for every result.
Integrity always.
About The Role
At Qodea, we believe in work that leaves a mark. This role is for the innovative people who thrive on solving problems that don't have answers yet, for those who are accountable for tangible outcomes, and for individuals who act with integrity when it absolutely has to work. Here, you will be responsible for leading the design and development of full-stack applications using Java and React, acting as both a technical consultant and a hands-on developer. You will have the opportunity to shape the direction of our projects while mentoring junior engineers and preparing for a future lead position.
