Senior Software Engineer - Full Stack

Job description

About the opportunity Join our Embedded Payments team as Sr. Fullstack Software Engineer in Pune, India to make a real impact every day. We say that because we know that every conversation we have, every code line we write and every interface we design is another opportunity for us to elevate everyday life experiences for our customers and the people and communities they serve. Reporting into the Director of Software Engineering , you'll take ownership of complex, cross-cutting problems across our cloud-native payment orchestration platform that processes significant transaction volume across multiple Xplor brands — from API contract through data model to UI. You'll be a technical anchor for your area: setting direction on design, raising the bar on code quality and testing, and mentoring mid-level engineers as the team scales. You're comfortable owning ambiguous problems end-to-end and collaborating closely with Product, QA, and DevOps to make sound trade-offs between speed and long-term platform health. We're looking for someone who treats AI tooling as a force multiplier. You should be fluent with modern AI-assisted development workflows (Claude Code, Cursor, Copilot, or similar) and have a point of view on how to use them well — where they accelerate work, where they need guardrails, and how to keep quality high as velocity increases.

We are looking for curious and empathetic people. We also love to hear from people who are motivated by meaningful work, resonate with our core values, have a positive outlook, are comfortable with ambiguity and thrive working in an ever-evolving and complex environment. We are inspired by meeting big-picture thinkers and doers, people who can be both tactical and strategic, aim high and put people first in everything they do. You'll need: 7+ years of professional software engineering experience, with a Computer Science/Engineering degree or equivalent Deep Node.js experience and a track record of designing and shipping production backend services at scale Experience building React-based frontends that consume RESTful APIs Demonstrated ownership across the full stack — you can independently scope, design, and deliver a feature from data model to UI Proven experience designing RESTful APIs and service-oriented or microservice architectures, including making and defending architectural trade-offs Strong working knowledge of relational databases (PostgreSQL preferred), data modeling, and service boundary design Substantial hands-on experience with AWS or a comparable cloud platform in a production environment Experience owning CI/CD pipelines (Bitbucket Pipelines, GitHub Actions, or similar), including release and rollback strategy Proficiency with Git, agile delivery, and testing frameworks like Jest Experience mentoring other engineers and influencing technical direction beyond your own individual contributions Fluency with AI-assisted development tools (Claude Code, Cursor, Copilot, etc.) and an articulate point of view on where they help and where they don't Comfortable working on a 100% remote team and able to operate independently while providing technical leadership within an agile group It would be great if you also have: Experience building or operating payments systems — payment orchestration, tokenization, acquirer integrations (Worldpay, Stripe, Adyen, Finix, Basis Theory), or PCI-compliant environments Familiarity with event-driven architectures (SQS, EventBridge, Kafka) Exposure to observability tooling (SigNoz, Grafana, Datadog, etc.) Infrastructure-as-code experience (Terraform) At Xplor, we believe that the best innovation and ideas happen at the intersections of our differences - people of diverse cultures, generations, disciplines, and lived experiences.
