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

Backend: C#/.NET, our primary language; the majority of our services live here

Cloud: Azure (Functions, Storage, and related services)

Frontend: TypeScript, Vue, PrimeVue

Testing: Automated testing is standard; TDD experience is valued

Comms: Remote-first, async-first; written communication matters as much as code

Delivery: Git-based workflows, CI/CD pipelines, and infrastructure managed as code where it makes sense

What You’ll Do

Own feature delivery end-to-end: from understanding the problem through to production, including build, deployment, and operational considerations

Lead and participate in code reviews focused on correctness, clarity, and maintainability

Mentor and unblock engineers on the team

Maintain and improve existing .NET solutions by reducing risk, technical debt, improving reliability and expanding features

Contribute to technical direction on new capabilities, not just implementation

Set and champion pragmatic engineering standards across the team

What We’re Looking For

Strong C#/.NET: 5+ years shipping and owning production software in C#

Real Azure experience: you’ve built and operated services there and you understand the failure modes

Sound design thinking: you break down ambiguous problems, make sensible trade-offs, and can articulate why

A quality mindset: automated testing, careful code review, and maintainable design are habits, not aspirations

Clear written communication: we’re fully remote, so your ability to write clearly matters as much as your ability to code

Full-stack comfort: you can work across the stack when the job calls for it

Nice to Have

Vue / PrimeVue experience

ASP.NET Core experience

Knowledge of the education sector

What We Offer

Salary: £45,000–£60,000 depending on experience

Fully remote: work from anywhere in the UK

5 weeks paid holiday plus bank holidays; more holidays added through years of service

Premium training resources and paid certification attempts

Annual team meetup and a budget to attend conferences and events each year

Good hardware and software: we won’t make you fight your tools
