Product Experience Designer - Lead - AI

Landytech is on a mission to revolutionise the way that investment managers, asset owners and their advisors access asset information. Powered by Sesame, an industry-leading investment reporting platform, we are helping clients in over 15 countries make informed investment decisions and deliver insights faster.

The company is growing rapidly and it’s an exciting time to join, having secured $12M in Series B funding in January 2023. In just four years, it has gone from two co-founders to a team of 80+ staff, with offices in London and Paris. At Landytech, we see diversity as our strength with a team from over 15 countries and 14 languages spoken.

The role

AI has made producing screens easy. It has not made products coherent. We are looking for someone to own the experience of Sesame end to end — the client journey, the interaction logic, the look and feel, and the consistency of all of it.

We have posted this role under two titles — Product Experience Designer and Design Engineer — to reach both backgrounds. Same role, same team. Apply once, to whichever fits you better.

How we work

We have rebuilt our product process around AI rather than bolting it on:

AI is used heavily at every stage of both design and engineering, not just at the production end

Our design system lives in code, used by engineers and AI tooling alike

Tooling changes every few months and we expect it to

You will have real scope to shape how we work, and to help build the parts that do not exist yet.

What you will shape

How much of this you lead outright will depend on your experience and on how it fits with the team already in place. There is room to take on more over time.

Client journey. The journey for investment professionals, family offices and their advisors — grounded in time spent with them, not personas

The experience model. How portfolios, positions, transactions and valuations are represented, related and navigated across the platform — and a strong voice when teams disagree

Look, feel and consistency. The product should feel like one thing, and you will help define what that one thing is

The design system. A living implementation in code, developed with our front-end engineers rather than a Figma library that drifts from production

Craft in dense financial interfaces. Tables that stay legible at scale, numbers at the right precision, drill-downs that survive a messy real portfolio

The must-have: setting the standard AI works to

AI is very good at producing attractive interfaces. Given a design system, almost anyone can now generate a credible screen.

The harder problem, and the one this role exists to solve, is making sure what we build expresses the product’s logic, density and intent rather than simply reusing its components. That means defining the standards and instructions our tools work to, reading the output critically enough to see why something is subtly wrong, and tightening the rules so it does not recur.

Using AI to produce interfaces is not the skill we are looking for. Directing it to our standard, consistently and at depth, is.

Strongly valued: front-end engineering experience

Designing the experience is half of it. Delivering it is the other half.

Build and ship, rather than only specify

Drive the design system with engineers as a shared artefact in code

Design for real production constraints: scale, loading and error states, ugly data

You do not need to be a full-time engineer. Comfort reading a component, working in a library such as shadcn/ui and reviewing a front-end PR goes a long way.

Also valued: product management instincts

If you have talked to clients directly, decided what not to build, and owned an outcome rather than a deliverable, we will weight it heavily.

What we are looking for

We do not expect anyone to have everything below — we would rather meet someone exceptional in two areas than adequate in all three.

5+ years designing B2B, analytics or data-heavy products, with deep UX expertise in complex domains

Systems thinking — you think in objects, relationships and states before screens

Real craft in dense data interfaces: tables, grids, charts, hierarchy, typography, restraint

Fluency with AI-assisted design as a working method, and the specification skill described above

First-hand user research — you get past what users say they do to what they actually do

Comfortable as an editor and enabler: reviewing others’ work, teaching, holding a line

Genuine curiosity about finance. You need not arrive knowing what a capital call is

Our process

Our interview process is likely to include a portfolio or work conversation, a short practical exercise based on a real Sesame flow, and a working session with a product manager and an engineer. We adapt the steps to the candidate and will always tell you what to expect in advance.
