Senior Frontend Engineer (React + Nx)

Senior Frontend Engineer

Payments & Financial Infrastructure (Remote)

A fast-scaling global payments and financial infrastructure company is building the front-end layer of how real money moves across borders .

The platform is used by SMEs and high-growth businesses to send, receive, and manage funds in real time across emerging markets, combining traditional payment networks with modern blockchain-enabled rails.

This is not consumer SaaS or a marketing site.
These interfaces sit directly on top of financial infrastructure , where clarity, accuracy, and trust matter as much as aesthetics.

The engineering team is fully distributed, product-led, and moving fast . Priorities evolve. Features ship quickly. External dependencies change. The expectation is simple: build interfaces that hold up when the stakes are real .

They are now hiring a Senior Frontend Engineer to own and evolve major parts of the frontend experience.

The Role (What This Actually Involves)

As a Senior Frontend Engineer, you won’t just “build screens.”

You’ll:

• Architect frontend systems that scale with a fast-growing product

• Translate complex financial workflows into clear, intuitive user experiences

• Own large parts of the UI that customers trust with real transactions

• Balance speed with precision when requirements evolve

This role is ideal for someone who enjoys autonomy, accountability, and responsibility , and who understands that good UI in fintech is about removing uncertainty — not adding flair.

What You’ll Be Doing

Frontend Architecture & Development

• Own and evolve frontend modules built with React, Nx, and TypeScript

• Architect scalable frontend systems and reusable component libraries

• Implement clean, accessible, responsive interfaces with high attention to detail

• Design UI patterns that remain stable under fast product iteration

Product & Cross-Functional Collaboration

• Work closely with product and design to shape user journeys and workflows

• Turn wireframes and requirements into production-ready, pixel-accurate experiences

• Collaborate with backend and DevOps teams to deliver seamless end-to-end functionality

• Ask the right questions when flows are unclear or risky

Financial Interfaces & Reliability

• Integrate complex financial and payment APIs into user-facing products

• Handle edge cases, errors, loading states, and partial failures elegantly

• Build interfaces where clarity and feedback matter as much as speed

• Design experiences that minimise user error around financial actions

• Quality, Performance & Maintainability

• Implement robust state management (Zustand, Redux Toolkit, or similar)

• Write unit and integration tests to keep the frontend stable as it scales

• Monitor and improve performance across browsers and devices

• Maintain clear documentation for components and architectural decisions
  

The Tech Stack

• Frontend: React, Nx, TypeScript, Redux Toolkit, Material UI

• Backend (context): .NET 8, PostgreSQL, DynamoDB

• Infrastructure & Tooling: AWS, GitHub Actions, Auth0, DataDog
  

Who This Role Is Really For

You’ll Likely Thrive If You:

• Have 5+ years building production-grade web applications

• Have worked on fintech, payments, blockchain, or financial products

• Care deeply about usability, precision, and user trust

• Are comfortable building complex flows, not just static views

• Can operate independently in a fast-moving, imperfect environment

• Enjoy owning features end-to-end rather than handing them off

• Take pride in building interfaces that quietly don’t fail

This Role Is Probably Not for You If You:

• Prefer purely design-led or marketing-focused frontend work

• Need slow, linear roadmaps with static requirements

• Dislike maintaining and improving existing interfaces

• Avoid responsibility for production issues

• Get frustrated when priorities shift or dependencies change

(Both are valid profiles — just not for this role.)

Nice to Have (Not Deal Breakers)

• Experience building or maintaining design systems

• Familiarity with Auth0 or similar authentication/identity solutions

• Experience using DataDog or similar observability tools

• Exposure to stablecoin or crypto-enabled payment flows

• Experience building dashboards or financial data interfaces
  

What Makes This Role Worthwhile

• Real product ownership: You’ll shape interfaces users rely on with real money

• High autonomy: Influence architecture, patterns, and frontend standards

• Fast learning curve: Early-stage scale means broad exposure and responsibility

• Remote-first: Work with a fully distributed team across regions

• Meaningful impact: You’re helping build financial infrastructure used in emerging markets
  

Final Note

This is a role for frontend engineers who:

• Think beyond visuals

• Care about correctness

• Enjoy responsibility

• And stay calm when things get messy

You’re not just building interfaces.

You’re building trust .
