Empower Your Future as Backend Intern at Juspay Today | 2025

If you or someone you know is passionate about SDE-Backend , loves solving real-world problems, and dreams of working in an engineering-first company — this post is for you

Let me introduce you to Juspay – a company that’s quietly powering millions of digital payments every day, without most users even realizing it. They’re one of the few firms where you get to code things that touch millions of people, build for massive scale, and learn how deep systems work -all while growing super fast.

What You’ll Work On

Juspay structures its work around Centers of Excellence (CoEs) — each solving a unique part of the payments puzzle. Here’s where you could fit in, based on your interests and skill set:

1. SDK & Frontend Experience

This is the team building the actual payment experience for end users — from selecting the payment method to that final success screen.

You’ll work on:

• Designing beautiful, responsive, and frictionless payment flows
• Building highly reliable SDKs that merchants can plug into their apps in minutes
• Integrating React-based components into Juspay’s own UI framework, Presto
• Creating native UIs for payments that work fast, offline, and across platforms

This is a dream job for people who love frontend development, React, animations, UI/UX, and design systems.

2. Backend Logic & Functional Programming

This team owns the actual logic behind every payment — and here’s the cool part: Juspay is India’s biggest functional programming company.

You’ll be:

• Writing backend logic using FP languages (like PureScript, Haskell, Scala)
• Designing systems that allow multiple retries, fallback routes, and security checks
• Working with payment aggregators, UPI, cards, and RBI systems
• Preventing failures even before they happen

If you love clean code, expressive logic, and zero tolerance for bugs, this is where you belong.

3. Data Science & Smart Payments

Every payment generates data, and Juspay uses that to build intelligent, self-healing systems. This team is shaping the future of AI-led payment operations.

You’ll work on:

• Training models to route transactions more efficiently
• Creating systems that auto-detect anomalies, failures, or fraud
• Building assistive bots that help users complete failed payments
• Developing real-time dashboards and rich data visualizations

If you love working with ML models, data pipelines, time series analytics, or just want to make complex systems smart, this is your playground.

4. Infrastructure & Reliability

Juspay handles more transactions per second than most startups do in a year. So you’ll be building infra that’s fast, reliable, and bulletproof.

You’ll get to:

• Architect multi-data-center (Multi-DC) deployments with seamless failover
• Use custom-built Infrastructure DSLs to manage systems at scale
• Manage edge devices, containers, and compute-heavy real-time jobs
• Ensure the platform achieves that golden number: 99.999% uptime

If you’re into DevOps, Kubernetes, cloud systems, reliability engineering, or building infra that never sleeps — this one’s for you.

Who Should Apply?

This opportunity isn’t about years of experience — it’s about how you think and what excites you.

You’ll do well here if you:

• Enjoy building systems that serve real people at massive scale
• Like learning about how the payments ecosystem works behind the scenes
• Are passionate about functional programming or curious to learn it
• Have an eye for detail and want to work in a company where excellence is non-negotiable
• Love low-code platforms, developer tools, or enabling others to build
• Are interested in making complex systems simple
• Want to grow fast and be part of a world-class engineering culture

You don’t need to be a payment expert or have a long resume — you just need to have the right mindset, and a strong base in problem-solving and clean coding.

Why Join Juspay?

Here’s what makes Juspay not just a place to work, but a place to grow.

• Learn From the Best: You’ll work with engineers who are deep thinkers and clean coders. If you’re tired of code that barely works, this will feel like a breath of fresh air.
• First Principles Culture: You’ll be encouraged to ask why before how. Build from scratch. Understand the fundamentals. Learn to think like a system architect.
• 10x Career Growth: The kind of scale you’ll deal with here — hundreds of millions of users, billions of rupees — will grow your thinking in months, not years.
• Deep Tech Stack: Be it PureScript, React, Presto, custom DSLs, or ML systems — you’ll use cutting-edge tools and contribute to open-source quality codebases.
• Ownership & Freedom: You’ll have the freedom to experiment, take ownership, and lead projects — regardless of your title or seniority.
