Juspay, the Bangalore-headquartered payments technology company behind infrastructure processing over 300 million transactions daily, is hiring a Software Development Engineer for its Backend team. This role sits within one of Juspay’s four “Centres of Excellence” (SDK, Backend, Data Science, and Infrastructure), specifically working on the business logic that handles evolving payment requirements — UPI, third-party integrations, and authentication flows.
One thing worth knowing upfront: Juspay is well known in the engineering community for building its core backend in functional programming languages — publicly, the company has talked extensively about its use of Haskell and PureScript, including a proprietary framework called Presto. The job posting itself doesn’t name a specific language, but its emphasis on “deep functional programming languages” and “concise expression of complex payment logic” lines up directly with that reputation. If you have zero exposure to functional programming (Haskell, PureScript, Scala, Elm, or similar), this is worth knowing before you apply, since it’s a real departure from typical Java/Python/Node backend roles.

What the Backend Centre of Excellence Works On
Juspay frames its engineering org around four Centres of Excellence, each balancing “Framework Development” with “Business Enablement.” The Backend team specifically focuses on:
- Business logic to handle evolving payment requirements — UPI, third-party integrations, and authentication — flexibly.
- Expressing complex payment logic concisely, leveraging Juspay’s functional programming approach across its entire business logic layer.
- API integrations connecting Juspay’s platform with banks, payment gateways, and other external systems.
The wider engineering org also includes SDK work (frictionless 1-click payment experiences using Juspay’s proprietary “Presto” UI framework), Data Science (intelligence from over a billion transactions — traffic routing, anomaly detection, self-healing systems), and Infrastructure (multi-datacenter architecture supporting 99.999% uptime).
Eligibility Criteria
This posting does not state a formal educational qualification, degree requirement, or years-of-experience range. Instead of a conventional requirements list, Juspay frames eligibility around interest and mindset. According to the posting, this role suits candidates who are:
- Enthusiastic about architecting frameworks using deep functional programming languages.
- Interested in solving reliability and performance problems that occur at large scale.
- Passionate about developing low-code and no-code platforms within a framework to streamline application development.
- Motivated to build self-service features that let end users efficiently modify and customize their own applications.
- Excited about supporting merchants of all sizes with minimal friction or issues.
Who Should Apply?
- Candidates genuinely curious about functional programming, even without prior professional FP experience — Juspay’s own hiring history shows it has taken on engineers willing to learn Haskell/PureScript on the job.
- Those interested in systems that operate at genuine scale (300M+ daily transactions) rather than smaller internal tools.
- Engineers who enjoy working close to core business logic — payment rules, integrations, authentication flows — rather than purely infrastructure or purely frontend work.
Who Is This Role Not For?
- Candidates who want to stay strictly within mainstream imperative/OOP languages (Java, Python, Node.js) without any interest in functional programming — this is a real and consistent theme across Juspay’s engineering culture, not incidental to this one posting.
- Those looking for a detailed, conventional JD with explicit years-of-experience and tech-stack requirements — this posting is written more as a culture/vision pitch than a structured requirements list, so ambiguity here is a feature of the source, not something FreshersJob4U can resolve for you.
Salary
Juspay has not disclosed a salary or CTC figure in the official posting. Candidates should confirm compensation directly during the interview or offer stage.
Selection Process
The official posting does not describe a specific test or interview format. Based on Juspay’s broader, publicly documented hiring pattern for engineering roles, candidates can generally expect a process involving a coding/DSA-focused online assessment followed by multiple technical rounds — with some rounds likely touching on functional programming concepts specifically, given the Backend team’s FP-heavy stack — and a final HR/behavioral round covering resume, projects, and cultural fit. Candidates should confirm the exact process directly with Juspay, since this isn’t stated in the job posting itself.
