About the role

As a Senior Frontend Engineer on the Payments Platform team, you'll build scalable, high-performance frontend infrastructure and user experiences that power payment flows for global merchants. You'll work closely with product, design, backend, and customer-facing teams to ship reliable, elegant, developer-friendly solutions used across multiple products and integrations. The role combines strong product thinking with engineering excellence — from building reusable UI systems and SDKs to optimizing performance, reliability, and scalability across our platform.

Responsibilities

• Design and develop scalable, performant, maintainable frontend applications using React, TypeScript, and modern web technologies.
• Build reusable UI components, shared libraries, and SDKs that support multiple products and integrations.
• Collaborate closely with Product, Design, Backend, and Customer-facing teams.
• Own features end-to-end — technical planning, architecture, implementation, testing, deployment, and monitoring.
• Optimize application performance, responsiveness, and reliability across devices and browsers.
• Code reviews, testing, documentation, and observability.
• Publish and manage SDK and NPM package versions, including backward compatibility and release management.

• Improve development workflows, tooling, and engineering best practices across the frontend ecosystem.

   

Requirements

• 5+ years of experience building modern web applications.
• Strong proficiency in React, TypeScript, JavaScript, HTML, CSS.
• Experience designing and maintaining reusable frontend architectures, component libraries, or SDKs.
• Experience managing NPM packages, versioning, and release processes.
• Experience building and maintaining frontend integrations with global payment platforms (Adyen, Stripe, Nuvei) — hosted components, wallets, alternative payment methods.
• Strong understanding of frontend performance optimization and modern browser behavior.
• Experience working with APIs and complex asynchronous flows.

• Excellent written and verbal English.

   

Nice to have / Advantage

• Familiarity with Next.js (SSR / App Router).
• Familiarity with additional frontend frameworks (Angular, Vue, etc.)
• Experience with cloud environments and CDN infrastructure (AWS preferred).

• Experience working in production-scale environments with high reliability requirements.

   

Must-Have Skills

• Go / Rust / TypeScript — core stack; strong proficiency in at least one, ideally two
• Multithreaded & concurrent programming — critical requirement; proven experience with real parallel systems
• Performance profiling & optimization — CPU/memory management under real production load on dedicated hardware
• Docker & containerization — deploying and managing containerized workloads
• Edge computing / embedded systems — experience building for resource-constrained environments
• Networking & distributed systems — solid fundamentals; building reliable comms between edge and cloud

• Real-time systems — low-latency design and delivery

   

Nice-to-Have Skills

• Video streaming / pipeline development
• Storage systems & data management at the edge
• Cloud services integration (AWS S3, GCP, MQTT, Kafka)
• AI/ML model deployment on edge devices
• Security concepts (encryption, secure communication, zero trust)
• Responsibilities
• Contribute to the core edge platform running across diverse hardware in a hybrid edge-cloud architecture
• Develop and integrate video management capabilities: streaming, recording, real-time AI processing
• Design and optimize for low-latency, high-performance workloads at the edge
• Build secure, efficient communication pipelines between edge devices and cloud systems
• Work with AI/ML engineers to deploy and optimize on-device models
• Own performance under load — profile CPU/memory, identify bottlenecks, fix them
• Participate in code reviews, debugging, and performance tuning across the stack
