Senior Software Developer
Senior Software Developer | C#/.NET | Fully Remote The Role SalamanderSoft builds user identity and account lifecycle management for the education sector. Our software manages 3 million accounts daily across 4,000+ schools, colleges and universities in 34 countries, integrating with Azure, Microsoft 365, Google Workspace and more. When it breaks, schools notice. When it works, they don’t, which means reliability, correctness and security aren’t aspirations, they’re requirements.We’re hiring a Senior Developer to take real ownership of parts of this platform: designing solutions, leading delivery, and raising the bar for how the team builds software. This is not a seat-warmer role. How We Work We’re a mid-sized engineering team who care about how software is built, not just that it ships. We work in an iterative, Agile way: small changes, regular feedback, and a bias towards shipping improvements early rather than late. We do code reviews to spread knowledge and find real mistakes, not to tick a box. We write automated tests because we’ve seen what happens when you don’t. We think carefully about design because maintaining poorly designed code is expensive and demoralising.You’ll be expected to do the same, and to help others do it better. Senior here means you let your work speak for itself and push the team to keep improving, not just that you have the years on a CV. The Tech Stack
