Senior Product Designer - L5

Street Group is one of the fastest-growing Prop Tech companies in the UK, building the technology estate and letting agents use to run their businesses.

We're looking for a Senior Product Designer to own onboarding for , our sales and lettings CRM. Switching CRM is a big decision for an estate agency. It means moving years of data, setting up branches, roles and permissions, and getting every agent confident from day one. That makes onboarding one of the most important areas for our growth, and we're rethinking all of it.

You'll own the end-to-end journey, from the moment an agency signs to the point their team is running their business on  You won't be handed a brief. You'll find the problems, decide what matters most, and work with our onboarding team, PMs, engineers, support and commercial to fix them.

How we work:

• Our users rely on us to run their businesses, so they love talking to us. You can spin up a call and test a prototype the same day. We don't guess; we ask.

• We don't believe in rigid, box-ticking processes. Sometimes you need a deep discovery phase; sometimes you just need to trust your intuition and ship. We trust you to know the difference.

• Partner with PMs and Engineers to shape the roadmap and decide what we build next. You'll identify problem areas worth solving and propose them - not wait for them to land in your queue.

• Define what success looks like before you ship. Measure how it performs after release using analytics, support data and customer feedback. Adjust.

• Jump on calls with users or visit them in-branch to understand pain points and test new workflows.

• Move from low-fi sketches to high-fidelity prototypes - picking the right tool and fidelity for the job, whether that's Figma, paper, or a Claude Code prototype.

• Leverage an AI-native, code-first workflow: use tools like Claude Code to "vibe code" small UI tweaks directly in the live product, get instant answers on technical constraints without waiting on engineers, and iterate your designs in the actual browser to drastically speed up feedback loops.

• Bring AI thinking to what we build, not just how we build it - design AI experiences in the product where they genuinely help users, and call them out where they'd be gimmicks.

• You want to own design end-to-end for significant work in your area - research through to shipping and measuring impact.

• You think from first principles and don't apply "standard" patterns blindly. You ask questions that narrow down the solution space and aren't afraid to challenge the status quo when you've got the evidence to back it up.

• You want to ship work that is polished, intuitive, and sets a new standard for the industry.

• You're commercially fluent - you understand that the user-optimal design isn't always the commercially right one, and you can make that trade-off without losing sleep.

• You've designed for complex products, and you care about the whole service, not just the screens.

• You prefer a strict, repetitive rhythm or a linear process without ambiguity, as you will find our pace stressful.

• You prefer to design in a silo. We challenge each other constantly to get the best result, so if you don't like engineers or PMs questioning your process, this isn't the place.

• You need to be told exactly what to do. We provide support, but we need people who see a problem and proactively chase the solution.

• You ship and move on. We expect you to define success upfront and check how the work performed after release.

• Experience: Roughly 5+ years of Product/UX Design experience (SaaS or complex product experience is a bonus).

• Tooling: Fluent in Figma and confident with modern design systems. Comfortable using AI tools across your workflow, including for shipping small changes directly to production.

• Research: You plan and run your own user research - picking the right method for the question, knowing how much research is enough to make a decision.

• Measuring success: You define what success looks like before you ship, and you check what actually happened after.

• Communication: You can articulate why you made a design decision to an engineer, a PM, or a commercial stakeholder - and adjust how you communicate depending on who's listening.
