We're looking for a Tech Principal to lead technical strategy and execution on our most ambitious product work: lighthouse projects inside Thoughtworks' general Customer Experience, Product and Design team.

Here's the shape of it. A client arrives with a big idea and not much time. Within a few days, you've helped them turn it into a concept everyone agrees on. Within a few weeks, there's something real that customers can actually use and react to. Within a quarter, it's live. Then you do it again, somewhere else in the world, with a different team, and you leave both of them better at it than they were before.

If you have built a career integrating strategy, architecture, AI engineering, and executive collaboration, this role offers an ideal platform to leverage those skills.

We call it 3/3/3

3 days: Product concept. Everyone aligned on scope, objectives and how we'll measure success.

3 weeks: Working prototype. Desirability, viability and feasibility tested with real users.

3 months: MLP launch. A production-grade minimum lovable product, ready to keep evolving.





Who You'd Work With

We work in tight forward-deployed pods: one Product Strategist, one Experience Designer, and two Forward-Deployed Engineers. You're one of the FDEs — the lead engineer on the pod — guiding architecture, delivery cadence, and technical commercial choices, while collaborating with the strategist and designer as equal partners rather than a downstream requirements queue. Some of the best moments in this job happen when team members explore a challenge from complementary perspectives and unlock innovative solutions.

On larger programmes you'll lead across multiple pods, each running its own 3/3/3 rhythm — sometimes a mix of Product Innovation, Modernization/Engineering and Data & AI pod types depending on the engagement shape. You'd report to Ahmet Sakar, Director of Technology for CXPD, and operate as part of a small Tech Principal cadre collaborating directly as peers.
