Senior Front-End Engineer

As a Senior Front-End Engineer, you will co-own the front-end experience for Performativ's trading and analytics platform,

building high-performance interfaces used by wealth managers and financial institutions. This is a hands-on engineering role with

direct ownership of architecture, implementation, and production outcomes.

The engineering team owns the platform that powers portfolio management, trading, analytics, reporting, compliance, and client

engagement at Performativ. Front-end engineers work closely with backend engineers, product, and design to turn complex financial

workflows into software that advisors can use every day.

The team ships continuously and gives engineers ownership over implementation decisions. On the front end, the current focus is

scaling a Next.js and React architecture across increasingly sophisticated workflows while keeping performance, server and client

boundaries, theming, and shared components under control.

We are looking for a Senior Front-End Engineer to co-own the quality, performance, and architecture of our trading and analytics

interfaces. This role is responsible for building production UIs, shaping front-end architecture, and raising the standard of our

shared component infrastructure.

You will work closely with backend engineering, product, and design to ship financial workflows from requirements through

production. You will co-own the end-to-end front-end scope, including server and client boundaries, hydration strategy, state

management, performance, multi-tenant theming, testing, and the component library used across the platform.

This role requires deep React and TypeScript expertise, strong architectural judgment, and the ability to turn complex financial

workflows into fast, usable interfaces. You need to be comfortable making implementation decisions independently and shipping

production software without management overhead.

This role is based in Copenhagen. We work together from our city-center office, with working from home possible when there is a

good reason. You should already be based in Copenhagen or be ready to relocate.

• Co-own front-end architecture across Next.js 15, React Server Components, TypeScript, and our shared application

infrastructure.

• Define server and client boundaries, hydration strategies, and state patterns that keep the platform responsive as complexity

grows.

• Use AI coding agents where they improve engineering throughput while maintaining control over code quality and implementation

decisions.

• Have built sophisticated production web applications with React and TypeScript and can structure front-end codebases that

continue to work as product complexity grows.

• Understand modern React architecture, including React Server Components and the Next.js App Router, or can demonstrate the

technical depth to become productive with them quickly.

• Have shipped production work using AI coding agents and understand where they improve engineering output and where direct

engineering judgment is required.

• Have improved front-end performance through decisions around bundle size, hydration, rendering, data fetching, and runtime

behavior.

• Are comfortable managing server state with TanStack Query and can make deliberate decisions about colocated state and client

state libraries.

• Understand usability, accessibility, and interaction design well enough to make sound UX decisions without treating design as

somebody else's problem.

• Have shipped tested production software using tools such as Vitest or Jest, Testing Library, Playwright, and automated CI/CD

pipelines.

• Work that reaches production fast. We ship weekly. Your work will be used by advisors and financial institutions within days,

not quarters.

• Colleagues who set a high bar. Our team comes from Goldman Sachs, McKinsey, BCG, and Amazon. Standards are high. Politics are

absent.

• Career compression. People here take on scope in twelve months that takes five years elsewhere. If you can carry it, we will

give it to you.

Wealth management runs on software built for a different era. Batch files. Overnight reconciliation. Client reports assembled by

hand. Advisors spend more time fighting their systems than advising clients. The industry has accepted this for thirty years.

We are replacing that layer. Performativ is one platform for portfolio management, reporting, compliance, and client engagement,

built from the ground up for how wealth is actually managed today. Banks, family offices, and independent advisors across Europe

run on it.

We are a scaleup, not a startup. The product is live, the customers are real, and the growth is ahead of plan. We intend to be the

system European wealth management runs on. That is not positioning. It is the plan we are executing against.

We are builders. We move fast, we say what we think, and we do not manage each other. Autonomy is the default, which only works if

you are the kind of person who does not need to be told twice.

This is not a role for someone looking to coast inside a growing company. It is a role for someone who wants scope, wants

pressure, and wants to point at something in two years and say they built it. If that is you, apply. If it is not, this will be

uncomfortable, and we would rather say so now.
