We're hiring Front-End Engineers to build the interfaces investment professionals use to inspect data, work with documents and direct AI agents. The hard part is trust and clarity: users need to be able to check an answer quickly, and they need to follow a long-running workflow while it's still in progress.
You'll join the UK core team and work in React, React Native and TypeScript. This role is part of a nine-person engineering cohort being hired across front-end and back-end
About Descrial
Descrial is a startup inside a twenty-year-old company
TresVista has run the analytical work behind private capital since 2006. 2,000 people, 400+ clients including some of the biggest names in the industry, no outside capital and no outside board. That was the first chapter. And we enjoyed getting here!
The next chapter is harder and more interesting
We are moving from services to software, from one firm's workflows to an industry's, and from executing investment decisions to shaping how they get made. Thirty of us in King's Cross, small and senior, with day one founder intensity.
At its fullest expression, Descrial changes how every serious investment firm decides.
The role
You report to the Head of Engineering and contribute to a shared component system that can be themed across tenants. Your work combines data-heavy enterprise interfaces with the performance and interaction design that AI-assisted workflows need.
Your remit
The product surfaces
You build advanced forms, analytics dashboards, real-time updates and rich document views in React and React Native with TypeScript. You make dense data usable through grid components such as AG Grid or MUI DataGrid, virtualisation and CSS Grid/Flexbox layouts that hold at scale.
The AI experience
You implement streaming responses, citations, verification affordances and safe failure states. For agent workflows, you make approvals, hand-offs, tool calls and partial progress visible, and let users interrupt or correct a run. You work on perceived performance so model calls taking seconds still feel responsive.
The shared platform
You contribute to the component library and tenant theming, keeping branding, permissions and configuration clean. You integrate backend APIs with authentication, role-based access, tenant context and useful client-side error handling.
The quality bar
You maintain unit, integration and end-to-end tests with Jest, React Testing Library and Cypress or Playwright, and meet WCAG 2.1 accessibility standards. You profile and optimise code splitting, lazy loading, memoisation and bundles through Jenkins and SonarQube pipelines to AWS.
Your experience
-
You have 5+ years in front-end engineering with deep React and TypeScript experience. React Native experience is valued.
-
You have shipped data-dense enterprise interfaces and can explain the grids, dashboards and state decisions behind them.
-
You understand state management, front-end security including XSS, CSRF and CSP, and testing discipline.
-
You have built SaaS or multi-tenant products and are familiar with Git, CI/CD and cloud deployment.
-
You use AI coding tools daily, such as Cursor or Claude Code, and have a considered view of where they help.
-
You have a degree in engineering, computer science or a related field, or equivalent experience.
Useful to have, none required
-
Interfaces for AI-assisted or agentic products
-
Micro-frontends, including Module Federation or comparable approaches
-
Contribution to or ownership of a design system

The reality
This will be difficult.
It demands pace and accuracy. We are building autonomous systems inside high-stakes live businesses, where decisions carry real consequences and impact and waiting for everyone to agree is not always an option. The systems will sometimes get things wrong. In this phase the London team needs to create the evaluations, visibilities and safeguards that catch mistakes early, reducing them over time and stopping the same failures happening again
If you want to build the foundations of an enterprise grade technology platform to service a multi-billion $ serviceable market opportunity, and share in that growth, this is your chance to join us.

Come ready to discuss three pieces of work:
-
A data-dense interface you shipped: the state, performance and usability decisions.

-
A quality or accessibility problem you found and the improvement you made.
Compensation
- The all-inclusive package is typically £85,000–£105,000 a year, depending on experience.
Practical details
-
King's Cross, London. In office (3 to 5 days a week), with colleagues in London and Bengaluru.

Apply
You do not need to meet every qualification to apply. Strong candidates bring different combinations of experience, judgement and potential, and we know that some people are more likely than others to underestimate what they could contribute. If the work interests you and you believe you could make an impact, we encourage you to apply.
The systems we are building will influence how important investment decisions are made. That makes a range of experiences and perspectives essential to building them responsibly. We want a team where different viewpoints are heard, respected and reflected in the work.
