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
T he 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.
