About the company

Let's see what we can create together!
The project and your role
Our client is rebuilding its guest-facing digital estate on a modern microservices architecture moving away from a fragmented collection of out-of-the-box portals toward a purpose-built digital platform that delivers personalised, seamless guest experiences across discovery, booking, pre-stay, and in-stay touchpoints. As a Digital Product Engineer, you'll build the digital products guests and staff use every day, working on a React/Next.js front-end and a back-end of independently deployable .NET 8 / ASP.NET Core microservices hosted on AWS.
- Build and maintain guest-facing features in React and Next.js — search, the booking funnel, conversion optimisation, and promotional campaign delivery, in partnership with commercial and marketing teams
- Deliver logged-in guest journeys on the guest portal, including pre-stay upsell, activity booking, and in-stay engagement
- Contribute to loyalty platform features — enrolment flows, member personalisation, and loyalty mechanics
- Design and build.NET 8 / ASP.NET Core microservices — REST APIs, domain logic, and integrations with core booking, CMS, and contact-center systems
- Deploy and operate microservices on AWS using Lambda and ECS/Fargate, choosing the right hosting model per service
- Implement event-driven communication between services using AWS SQS, SNS, and EventBridge
- Design RESTful APIs to agreed standards, including OpenAPI specifications, versioning, and documentation
- Write unit, integration, and end-to-end tests, and ship through CI/CD (GitHub Actions)
- Participate in code reviews with nearshore engineering partners and take ownership of your services in production, including incident response
