About Stafflink

At Stafflink, we help global companies build and manage world-class teams. We're currently hiring very senior, product-minded Full Stack Engineers in Lahore for a high-growth international Fintech SaaS client that's building the future of financial services.

This isn't your typical dev job — we're looking for tech leaders, system thinkers, and engineers who can architect entire platforms and ship with confidence.

Your Role

As a Principal / Senior Full Stack Engineer, you'll take full ownership of features from backend architecture to frontend performance, working in a highly technical, fast-moving product environment. You'll help define architecture, mentor other engineers, and build secure, scalable fintech systems used by thousands globally.

What You'll Be Doing

• Lead the design, development, and deployment of complex web applications
• Build secure, high-performance fintech features (payments, onboarding, KYC, etc.)
• Architect scalable SaaS infrastructure in collaboration with cloud/DevOps teams
• Work closely with Product and Design to translate business needs into technical solutions
• Ensure high standards of security, performance, and maintainability
• Conduct code reviews, mentor mid-level and junior engineers
• Own technical decisions end-to-end — from database schema to UI interactions
• Stay on top of fintech compliance, scalability, and data handling best practices

Tech Stack (Preferred)

• Frontend: React, Next.js, TypeScript
• Backend: Node.js (or Python/Go/Java if experienced), REST & GraphQL APIs
• Databases: PostgreSQL, MongoDB
• Cloud & DevOps: AWS, Docker, Kubernetes, CI/CD, GitHub Actions

What We're Looking For

• 7+ years of hands-on development experience in full stack roles
• Proven experience building and scaling SaaS or Fintech products
• Deep understanding of system design, microservices, caching, and data modeling
• Strong knowledge of secure coding practices & financial compliance (PCI, KYC, SOC2)
• Experience working in high-ownership, startup-like environments
• Leadership qualities: ability to mentor, make architectural decisions, and move fast with confidence
• Strong communication, documentation, and collaboration skills
• Must be based in Lahore or willing to relocate — this is a 100% onsite role

Nice to Have

• Experience with blockchain, smart contracts, or embedded finance
• Background working with real-time systems or large-scale data handling
• Hands-on experience with testing frameworks and CI/CD automation
• Past experience in a founding engineer or early-stage startup role

What We Offer

• Work directly with an international fintech SaaS team on meaningful problems
• High-end market salary based on skills & seniority
• State-of-the-art office environment in Lahore
• Opportunity to lead and grow into a tech leadership role
• Long-term career growth, bonuses, and impact-driven culture
• No micromanagement — just ownership, performance, and great engineering
