Senior Frontend Developer (React)

You will become a member of the Money & Volume (M&V) front-end squad based in Lisbon. The squad works closely with the M&V back-end team.

Responsibilities

You will become a member of a global Tech team located in Oslo, Helsingborg and Lisbon, building a multilanguage, highly scalable, cloud native, multi market broker and membership platform, with a bare minimum of legacy code.

Owns significant front-end features end-to-end on the Money & Volume (M&V) surfaces of the Axo platform — React and TypeScript.

Works in an AI-First engineering culture where Claude Code and AI-assisted development are daily workflow, not optional extras.

Bridges product thinking, strong architecture instincts, and practical delivery — shipping multiple features a week while maintaining the quality standard that financial data demands.

Contributes to architectural direction, mentors junior developers, and collaborates across product, design, and data.

How we build:

• a large pnpm + Turborepo monorepo (20+ Next.js apps, 100+ shared packages) serving multiple brands and markets across the Nordics.
• Next.js (App Router) SSR for the public and customer surfaces, deployed primarily on Vercel.
• A deliberately opinionated, headless data architecture that decouples data-fetching from components, evolving toward a fully headless data-access layer.
• AI-assisted, spec-driven development is the default daily workflow, and much of the product surface ships flag-gated for A/B testing — and may be deleted once the data speaks.
• Experiments exist to move commercial outcomes — conversion, ticket size, cross-sell — not engagement for its own sake.
• We are not looking for someone who has memorized this exact setup — it is bespoke. We want someone with the underlying instincts (decoupling data from views, cache and invalidation reasoning, state modeling, knowing when to experiment vs. when to build to last) who is energized rather than unsettled by an opinionated architecture.

• Your responsibilities will grow to match your abilities and experience.

• Own complete front-end feature development from spec through deployment — React / TypeScript

• Lead architectural discussions - document decisions in lightweight specs and plans (spec.md / plan.md)
• Build and review AI agent workflows using Claude Code, or equivalent tools — delegate implementation, review all output
• Build responsive, accessible UI and integrate with platform and financial APIs (REST / GraphQL)
• Grow into fullstack — take on backend work in Go as you progress, starting with domain modelling and resource-oriented API design (owning the data-access layer over time)
• Learn to enforce GDPR and EU AI Act compliance requirements in every feature — data privacy is architecture, not a checkbox
• Mentor mid-level and junior engineers; set the bar for code quality and AI-assisted development practices

Experience requirements

Must-Have skills: Frontend — React

• 5+ years front-end experience; 3+ years building production React
• Strong command of modern React — hooks, composition, render/performance behavior, and when not to reach for a hook
• Strong, idiomatic TypeScript across a large codebase — generics, discriminated unions, inference, typing shared library boundaries (not just typing props)
• Writes clean, component-driven code with clear separation of concerns
• Solid grasp of state management and data-fetching patterns, and the judgment to decouple data-fetching from components: cache invalidation, request/loading/error state modeling, optimistic updates, deduplication, and validating data shapes at the network boundary rather than trusting the wire
• Comfortable instrumenting what they ship — event tracking for measurement, and reading experiment results to know whether it worked
• Comfortable consuming and integrating resource-oriented REST APIs, including our headless CMS
• Works effectively in a large shared codebase / monorepo — respects package boundaries, reasons about blast radius, does not just tend their own corner
• Hands-on experience with a modern SSR React framework — data loading, streaming, caching layers, the client/server boundary (where most of our surface area lives)
• A modern JS/TS test runner and React Testing Library — tests behavior, not implementation
• Component-driven development with isolated component testing and visual/interaction regression tooling
• Treats a green pipeline and trunk-based development as table stakes — small, frequently-merged changes, not long-lived branches
• Comfortable with debugging and performance tuning

UI craft & collaboration

• Builds responsive, accessible UI (WCAG-aware) with attention to UX
• Strong HTML / CSS and modern JavaScript / TypeScript fundamentals
• Comfortable working within a shared, multi-brand design system and component library — design tokens, theming, and accessibility built into shared primitives rather than reimplemented per surface
• Collaborates closely with design and back-end on shared API contracts

Nice-to-have:

• Existing daily use of agentic coding tools - able to describe and demonstrate a personal AI development workflow and tooling setup (e.g. CLAUDE.md, project rules, context engineering) - is a strong plus, not a prerequisite
• Genuine interest in growing into fullstack — willing to learn Go for back-end work (the growth path for this role)
• Any back-end exposure (Go, Node, or similar); experience in regulated / fintech environments (GDPR, handling financial/personal data)
• Domain modelling and resource-oriented API design — the first proficiency on the fullstack growth path, leading to owning the data-access layer
• Knows how to write and review Architecture Decision Records (ADRs), Low Level Design (LLD) and High Level Design (HLD) documents — useful as you take on more architectural ownership
• Large-monorepo tooling (pnpm workspaces, Turborepo): build graphs, affected-based CI, shared-package versioning
• Core Web Vitals / INP optimization, SSR performance, edge/CDN caching, bundle-size discipline
• Multi-brand / multi-market / i18n product experience
• Feature-flag / experimentation platforms (e.g. Statsig, LaunchDarkly); observability tooling (e.g. Sentry); behavioral analytics
• Experience with React Hook Form (or equivalent) for complex form state

BSc/MSc in computer science, engineering, or related discipline OR extensive relevant work experience
