Senior Frontend Engineer
Payments & Financial Infrastructure (Remote)
A fast-scaling global payments and financial infrastructure company is building thefront-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.
