Job summary

First Line Software, based in the United Kingdom, seeks a Digital Product Engineer to build the guest-facing digital platform using a React/Next.js frontend and a backend of independently deployable .NET 8 / ASP.NET Core microservices hosted on AWS.

You will deliver guest-facing features across discovery, booking, pre-stay and in-stay touchpoints, and collaborate with marketing, commercial teams, and nearshore/offshore partners in an agile environment.

Qualifications

• 2+ years of software engineering experience spanning front-end and back-end development.
• Hands-on, production experience with React and Next.js — App Router, server components, SSR/SSG.
• Hands-on, production experience with .NET (Core/.NET 5+) and C#; .NET 8 / ASP.NET Core strongly preferred.
• TypeScript across the stack.
• Demonstrable experience building and deploying microservices on AWS (Lambda and/or ECS/Fargate).
• Experience with RESTful API design in a microservices architecture.
• Experience working in agile sprint teams, ideally alongside nearshore or offshore engineering partners.
• Consumer-facing product experience — eCommerce, hospitality, travel, or retail preferred.
• English language proficiency for technical documentation and team communication.

Responsibilities

• 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.
