Platform Engineer (PCI DSS & AWS)

Location - Remote - India

Salary - £25,000 - £35,000 + Equity

Working Pattern - Full-Time | Fully Remote

Company Overview

Our client is one of the most innovative businesses currently operating within travel payments.

They have developed a market-leading payment solution that allows travellers to split the cost of a booking across multiple payment methods, multiple cards and even multiple people.

Unlike Buy Now Pay Later providers, this solution does not involve lending or consumer credit. Instead, it enables travellers to spread the cost of a booking across debit cards, credit cards and alternative payment methods, or invite friends, family members and travel companions to pay their share directly through a simple payment experience.

The platform is already being used by leading travel brands and airlines, helping increase conversion rates, reduce abandoned bookings and unlock revenue that would otherwise be lost during the checkout process.

Having successfully established themselves within the travel sector, the business is now entering its next phase of growth and investing heavily in platform security, infrastructure and compliance as they continue to scale their enterprise customer base.

Role Summary

We are looking for a Platform Engineer to take ownership of infrastructure, security and compliance across a growing travel payments platform.

This is a rare opportunity to become the first dedicated Platform Engineer within the business and the first engineering hire based in India.

One of your first major projects will be helping the business achieve PCI DSS compliance, working closely with the founders and engineering team to strengthen security controls, improve infrastructure maturity and establish the processes required to support continued enterprise growth.

The platform is already being used by major travel brands and airlines, and as adoption continues to increase, security, compliance and platform resilience have become strategic priorities for the business.

You will have significant autonomy from day one, taking ownership of security and infrastructure initiatives while helping establish best practices across the wider engineering organisation.

This role would suit somebody who enjoys ownership, wants to make a visible impact and is excited by the opportunity to build the foundations of a rapidly growing fintech business.

As the business continues to expand, there will be a clear opportunity to build a team around you and progress into a leadership position in the future.
