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.

The approach you'd be leading: 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.

Think of it as a reference tempo rather than a fixed schedule. The sequence is what we believe in: align quickly, get real evidence early, put something usable in front of customers while the idea is still current. A regulated platform with a heavy integration surface won't run like a greenfield mobile app, and reading the difference is part of the job.

AI runs through all of it, and not as a feature we add at the end. We use AI across the whole lifecycle, from specification and design through build, test and operations, and you'd be one of the people defining what good looks like there.

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 collabo
