Full Stack Developer (React + Node.js)

About Sliq Group

Sliq Group is a tech consulting and product engineering company. We build scalable digital products, e-commerce platforms, and custom web applications for startups, mid-market businesses, and enterprises. Our teams focus on strong engineering fundamentals, clean architecture, and reliable delivery.

Why This Role Exists

To build a scalable, multi-tenant SaaS application from the ground up, we need an experienced Full Stack Developer who can take complete ownership of features from start to finish. This is not a "code-only" role. You will work closely with stakeholders, drive key technical decisions, and help shape a secure, reliable, and scalable SaaS architecture that can grow with our customers.

What You Will Do

• Take end-to-end ownership of features, from requirement discussions and technical planning to development, testing, deployment, and post-release support.
• Actively engage with all stakeholders (project managers, designers, QA, business teams, and clients) to understand requirements, clarify gaps, and give regular progress updates.
• Build responsive, high-performance SaaS user interfaces using React.js, including dashboards, admin panels, and role-based views.
• Design and develop scalable RESTful APIs and backend services using Node.js and Express.js
• Architect and implement core SaaS capabilities such as multi-tenancy, role-based access control (RBAC), user and organization management, and subscription billing
• Drive system architecture decisions, including service design, tenant data isolation, data flow, caching, queues, and integrations
• Design tenant-aware database schemas and write efficient, optimized queries (PostgreSQL/MySQL and/or MongoDB)
• Integrate third-party services such as payment and subscription gateways, SSO/authentication, email/SMS, webhooks, and cloud storage.
• Proactively identify risks, blockers, and technical debt, and propose practical solutions.
• Set coding standards, lead code reviews, and mentor junior developers
• Ensure application security, performance, uptime, and scalability as the user base grows

What We Are Looking For

Must-Have Qualities

• End-to-end ownership: you treat the product as your own and see tasks through to completion without constant follow-ups
• Active stakeholder participation: comfortable joining client and internal discussions, asking the right questions, and communicating clearly with both technical and non-technical people
• Collaborative mindset: works well across teams, shares knowledge, gives and accepts feedback openly

Must-Have Skills

• 4 to 6 years of hands-on experience in full-stack development, with at least 2 years building SaaS products
• Proven experience working on complex architectures, such as multi-tenant systems, microservices, event-driven designs, or high-traffic platforms
• Strong understanding of SaaS fundamentals: multi-tenancy, RBAC, subscription and billing flows, usage limits, and tenant data isolation
• Strong proficiency in JavaScript (ES6+), React.js, Hooks, and state management (Redux, Zustand, or Context API)
• Solid experience with Node.js and Express.js for building REST APIs
• Strong experience with relational and/or NoSQL databases (PostgreSQL, MySQL, MongoDB), including schema design and query optimization
• Experience with caching and queuing tools such as Redis, RabbitMQ, or Kafka
• Good understanding of HTML5, CSS3, Tailwind CSS or similar frameworks, and responsive design
• Experience with authentication and authorization (JWT, OAuth 2.0, SSO, role-based access)
• Solid understanding of application security best practices (OWASP, data encryption, secure API design)
• Proficiency with Git and collaborative workflows (branching, PRs, code reviews)
• Ability to translate Figma designs into pixel-accurate UI

Good-to-Have (Add-On)

• DevOps knowledge: CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins), Docker, server setup, environment management, and monitoring
• Hands-on experience with cloud platforms such as AWS, Vercel, or DigitalOcean
• Experience with Next.js or TypeScript
• Experience with subscription billing platforms (Stripe Billing, Razorpay Subscriptions, Chargebee)
• Experience with automated testing (Jest, Cypress, Playwright)
• Exposure to compliance standards such as GDPR or SOC 2

What We Offer

• Real ownership in building a SaaS product from scratch
• Direct exposure to stakeholders and decision-making
• Opportunity to influence product architecture and technical direction
• Modern engineering practices and tools
• Clear growth path toward Tech Lead or Solution Architect roles
