We’re looking to hire a Senior Frontend Engineer located within Africa to join our fast-growing, fully remote team. You will join our Commercial Pod, the team that owns the systems our commercial business runs on: trade execution, treasury operations, commercial operations, and the internal tooling our operations teams use every day.

As a Senior Frontend Engineer, you will own significant surfaces of our B2B suite and contribute to the shared design system that other pods build on. You will collaborate closely with our Technical Lead, Product Managers, designers, and backend engineers to deliver interfaces that hold up under money-movement scrutiny.

Candidates with experience in FinTech or Crypto products are strongly preferred. We value clear communication, strong ownership, and engineers who are passionate about delivering exceptional user experiences.

Our technology stack includes: Vue 3 (Composition API), TypeScript, Pinia, Vite, Vitest, Storybook, SCSS with Figma-derived design tokens, our internal design system published to AWS CodeArtifact, Node.js, Serverless Framework, AWS Lambda, DynamoDB, AWS SQS, SNS, EventBridge, EKS, Valkey, Datadog, GitHub Actions, and more.

What You'll Do

• Own end-to-end delivery of frontend features across the internal tooling products, from design doc through to production and post-release monitoring
• Build and extend components in our Vue 3 design system, caring about the API surface other engineers consume and not just the pixels
• Integrate against REST APIs fronting our serverless and EKS services, designing for real-world async behaviour: eventual consistency, retries, idempotent submissions, and partial failure states a user has to understand
• Instrument what you ship, so frontend work is observable in Datadog and carries correlation IDs through to the backend
• Write and review design docs, take part in our design doc review sessions, and run Knowledge Sharing Sessions for the wider engineering org
• Provide clear and concise communication and updates regarding feature development statuses to the team and stakeholders
• Adhere to internal coding standards, development processes, and design best practices, and help shape them as our engineering standards mature
• Ensure quality through thorough testing and peer review of your work and the work of cross-functional teams
• Take part in the Commercial dev support rota, roughly once every five weeks
• Embrace and demonstrate our values: humility, creativity, and independence
• Write and maintain clean, maintainable, and well-tested code for the future (and present) of the company’s platform

What You'll Bring

• 5+ years of experience as a Frontend Engineer (full-stack experience is a plus but not required)
• Expert-level proficiency with Vue 3, the Composition API, and TypeScript. Strong React or Svelte engineers who can make a credible case for picking up Vue 3 quickly will be considered
• Deep understanding of modern JavaScript, component-based architecture, and state management patterns such as Pinia
• Strong experience with modern CSS and SCSS, token-based styling, responsive design, and cross-browser compatibility
• Proven experience building and optimising scalable, high-performance UIs, including data-dense surfaces such as tables, dashboards, and forms with hard validation rules
• Real experience building or maintaining a shared component library or design system, including versioning, breaking changes, and consumer migration paths
• Strong experience working with RESTful APIs and integration patterns, and comfort reasoning about distributed backends and failure
• Solid understanding of frontend application security, including XSS, CSRF, content security policies, and secure client-side data handling
• Experience working with AWS, especially in contexts relevant to frontend (CloudFront, S3, Cognito, CodeArtifact)
• Experience with testing tools such as Vitest, Jest, Vue Test Utils, Cypress, or Playwright, and with Storybook for component development

What Would Make You Stand Out

• Experience in FinTech, Crypto, or other highly regulated environments, especially anything involving FX rates, trading, or money movement
• Exposure to African markets or other multi-currency, multi-regulator environments
• Knowledge of serverless architectures and how frontend apps interact with them
• Familiarity with performance monitoring and observability tools, particularly Datadog RUM, logs, and traces
• Understanding of web accessibility standards (WCAG 2.1 AA) and best practices
• Experience with CI/CD pipelines for frontend deployments, and with automated release tooling such as release-please and Conventional Commits
• Experience deprecating and migrating off a legacy frontend without freezing product delivery
• Practical use of AI coding tools in your daily workflow

Team

• Exude your upbeat energy and enthusiasm every day to motivate your team to be the best they can be in every aspect of what they do
• Celebrate the success of others by recognising the contributions of committed team members and their achievements
• Clear and accurate written and verbal communication is a must
• Collaborate with your peers to collectively think of innovative ideas that drive business through technology
• Build and utilise working relationships with internal business partners across the organisation and external business contacts
• Keen interest in learning and sharing current trends and advancements in modern web and back-end frameworks

What We Offer

• Compensation & Benefits: We offer competitive compensation and meaningful health coverage, and all full-time employees are participants in our stock option plan.
• Learning & Development: Access to resources, support, and autonomy to grow professionally.
• Remote-First Flexibility: We embrace a fully remote work environment.
• Mental Health Support Services: Your mental well-being matters to us.
• Global & Diverse Team: You will have the opportunity to work with talented professionals from 24+ countries across the world, in a multicultural and collaborative environment.
• Global Impact: You’ll be part of a team shaping the future of global FinTech and stablecoin accessibility.
