ABOUT THE ROLE:

We’re looking for a Software Engineer to join the Firefly team, which builds and operates Flight Info Alerts, a platform that distributes flight schedules and status updates to subscribed clients. You’ll help design and run production services on our Azure cloud infrastructure, working with C# and Java. You’ll have the opportunity to deepen your coding skills and to gain hands-on experience with infrastructure, pipelines, and system architecture. You’ll join a small, autonomous engineering team and split your time between shipping new features, evolving our platform architecture, and maintaining legacy products that are on a clear deprecation path.

WHAT YOU’LL BE DOING:

• Building, running, and improving scalable back-end services for our Flight Info Alerts product, using cloud-native patterns on Azure
• Developing and operating event-driven systems that process and distribute flight schedules and status updates at scale
• Developing and maintaining services in C#, and picking up Java when needed to support and evolve our existing codebase
• Working with infrastructure as code (Terraform), contributing to CI/CD pipelines, and helping automate deployments
• Contributing to discussions and decisions that shape system architecture and the technical direction of the platform
• Identifying and resolving technical debt, performance issues, and reliability risks before they escalate
• Being a reliable team partner: sharing knowledge, taking part in code reviews, and helping maintain high engineering standards
• Handling a broad range of work as team needs evolve, including infrastructure updates, pipeline work, feature development, and operational support

WHAT WE’RE LOOKING FOR:

• Experience building and operating production back-end services in C# / .NET
• Hands-on experience with Microsoft Azure and cloud-native architectures
• Experience with AI or ML technologies in a production context
• Experience with event-driven or distributed systems
• Attention to detail, with a focus on scalability, reliability, and maintainability, and the ability to take work from design through to production
• Willingness to take part in technical decisions and to explain the trade-offs behind them
• A continuous-improvement mindset: you’re happy to question existing solutions, refactor legacy systems, and solve problems together with the team
• Willingness and ability to pick up additional technologies (such as Java) when needed
• The ability to work autonomously while being a strong team member across a broad range of technical work
• Nice to have: experience with infrastructure as code (Terraform or similar) in CI/CD-driven environments
• Fluent English (B2 or higher)

WE WILL OFFER YOU:

🚀            A progressive, non-hierarchical culture where innovation drives everything we build

🏡            Flexible working arrangements that allow remote work or office attendance

💰            An attractive compensation and benefits package, including private health insurance from day one of   joining, a company bonus scheme and company pension scheme
