Description

Our Mission and Vision At Solidgate, our mission is clear: to empower outstanding entrepreneurs to build exceptional internet companies. We exist to fuel the builders — the ones shaping the digital economy — with the financial infrastructure they deserve. To achieve that, we’re on a bold path: to become the #1 payments orchestration platform in the world. About the Team and Role We’re looking for a Node.js Engineer to join our Web Platform team — a critical part of our Platform Stream. The Stream builds the core systems every product team depends on. Our Web Platform team provides a unified set of services that power product delivery across the company: Full-stack product solutions for authentication and authorization, audit logging, analytics, user and file management Developer tools such as feature toggle, and tools to work with them (SDK, CLI, CI/CD integrations, testing utils) JS/TS platform libraries for observability (logging, metrics, health), synchronous and event-driven communication, and middlewares for platform solutions like authentication and audit logging DevOps: managing and improving Node.js and Front-end CI/CD pipelines and operational efficiency Front-end foundations: Unit design system with flexible in-house components and widgets A reliable multi-channel notification platform that orchestrates merchant onboarding, document workflows, and approval processes across the organization will be in your hands. You'll architect and evolve the Node.js infrastructure that powers these systems — designing for resilience, observability, and performance at scale. You'll also drive architectural decisions around authentication/authorization patterns, platform SDK design, event-driven messaging, and observability infrastructure — while building developer experience tooling that accelerates delivery across engineering teams. Platform Engineering — Engineering For Engineers Platform work gives you the best of both worlds: deep technical challenges and immediate impact. You build systems that help product engineers solve complex problems. You create infrastructure that scales, evolves, and unlocks speed for dozens of teams. This is high-leverage engineering — and it shows. Explore our technology stack ➡️ here. We hire for fire — Node.js must light you up! Full-stack? Great. You’re welcome to apply. Just know this role is 80% backend, so most of your time will be building, scaling, and owning Node.js platform services. What you’ll own — Services that supercharge our web products — think file manager, PDF generator, messaging, and notifications. — Node.js platform solutions: CI/CD, audit logs, feature toggles, auth, logging, and observability. — Making rock-solid solutions from day one with Shift-Left testing — unit, integration, and end-to-end. What We Pay Attention To: Technical Mastery You know your way under the hood: — Node.js & TypeScript — You understand async/await, streams, module resolution (CJS/ESM), and the nuances of TypeScript’s type system. — Systems & Databases — You’ve built products and tools for other engineers, handled large, complex (enterprise-scale) systems, and worked with high-volume SQL databases like PostgreSQL or MySQL. — Architecture & Design — You’re fluent in microservices, OOP/OOD principles, and SOLID/GRASP patterns. — Testing — You write reliable unit, integration, and end-to-end tests (e.g. Jest, Vitest, Cypress/Playwright, or similar). — Complex Systems — You can navigate, debug, and optimize large-scale, high-impact systems without breaking a sweat. Mindset & Impact You don’t just ship code — you own outcomes: — Product mindset — You think end-to-end and build solutions that solve real problems for users. — Ownership & independence — You take full responsibility for your work, drive projects forward, and make confident decisions. — Ability to learn quickly — You pick up new technologies, patterns, and processes without waiting for instructions. — High standards & accountability — You hold yourself and others to high standards, especially when working with production systems, ensuring everything you deliver is reliable and top-quality. The Points That Make You Stand Out: — Experience with APIs & cloud services: gRPC/tRPC, REST, Docker, AWS, AWS Fargate. — Familiarity with queues and streams: RabbitMQ/SQS/Kafka/ NATS. — Solid understanding of DevOps and platform tooling: CI/CD, GitHub Actions, GitLab pipelines. — Exposure to observability tools: Grafana, Prometheus. — Hands-on experience with frontend frameworks: React, Vue, Angular, or similar. — A track record of open source contributions. Why Solidgate? High-impact role. You’re not inheriting a perfect system — you’re building one. Great product. We’ve built a fintech powerhouse that scales fast. Solidgate isn’t just an orchestration player — it’s the financial infrastructure for modern Internet businesses. From subscriptions to chargeback management, fraud prevention, and indirect tax — we’ve got it covered.
