Senior Full-Stack Engineer (API Platform)

About :

We’re building a next-generation API management platform designed for developers and administrators to onboard, edit, and govern APIs with high performance, real-time validation, and intelligent tooling.

We believe in owning end-to-end solutions, building intuitive, maintainable systems, and enabling developers with the tools they deserve.

Role Overview

As a Senior Full-Stack Engineer, you will own the development of our editor hub, dashboard, and supporting backend services. You will be responsible for delivering a responsive, scalable, and maintainable product, collaborating with product, design, and infrastructure teams. You’ll influence architecture, state management strategy, and modular component design.

Key Responsibilities

• Design, implement, and evolve a React + TypeScript front-end for an editor-centric enterprise application.
• Integrate Monaco Editor for real-time contract editing (OpenAPI specs) with syntax highlighting, validation, and error reporting (e.g. via Spectral).
• Manage application state using lightweight frameworks (e.g. Zustand, Recoil), avoiding unnecessary Redux complexity.
• Build Fastify-based Node.js backend services to support API validation, schema management, session/lock handling, and integrations.
• Model, query, and operate on data via MongoDB (schema design, aggregation pipelines, transactions, indexing).
• Write unit tests using Jest and end-to-end tests using Playwright.
• Develop a responsive, theme-able UI using Tailwind CSS, design tokens, and component-driven architecture.
• Collaborate closely with UX/UI designers to turn wireframes and mocks into polished, user-friendly interfaces (dashboards, side panels, widgets).
• Prioritize performance, scalability, and clean architecture across modules and features.
• Identify and refactor technical debt; mentor more junior engineers.
• Participate in code reviews, design discussions, and planning sessions.

Required Skills & Experience

• Strong experience with React + TypeScript (hooks, context, component composition, patterns).
• Solid Node.js skills; experience with Fastify preferred (Express acceptable).
• Experience with state management solutions other than Redux (Zustand, Recoil, Jotai, etc.).
• Deep understanding of MongoDB (schema modeling, queries, transactions, indexing, performance tuning).
• Proficiency with Tailwind CSS, utility-first styling, responsive design, and theming.
• Proven experience writing unit tests and E2E tests (Jest, Playwright or equivalent).
• Solid grasp on REST APIs, concurrency, locking / session management, and distributed systems fundamentals.
• Familiarity with Docker for containerization (and some exposure to Kubernetes or orchestration)
• Strong software architecture sense, modular design, clean code practices, and ability to reason about scaling.

Nice-to-Haves

• Experience integrating Monaco Editor or building web-based IDE / contract editors.
• Knowledge of Azure Key Vault, Azure API Management (APIM), or API lifecycle tools.
• Experience in CI/CD pipelines, automated deployments, cloud-native architectures.
• Past work on collaborative or multi-user real-time applications (CRDTs, OT, conflict resolution).
• Familiarity with distributed locks, Redis, or similar concurrency tooling.
