Remote Online - Full Stack Developer (.NET | React)

Hi, I’m Paul, founder of Remote Online. For the past 25 years my wife and I have been building custom software that keeps real-world businesses running smoothly - think smoother logistics for Volvo or streamlined ops for mid-market firms pushing past £20 million in revenue. We’re a small UK-based shop of 16 tech-loving problem-solvers who believe smart code + good people = long-term success. I’ve never been one for corporate fluff. We keep hierarchy light, lean on AI and modern tooling, and back each other to get stuff done without drama. People stick with us because they own their work, learn fast, and have fun doing it. If this sounds like a place for you, read on!

We’re looking for a Full Stack Developer (.NET / React.js) who enjoys crafting robust back-end services and slick front-end experiences. You’ll thrive here if you’re proactive, detail-oriented, and fired up about helping clients scale through better systems.

• Support system architecture and contribute to technical decisions
• Ensure the codebase is clean, secure, scalable and well-tested
• Participate in code reviews and continuous improvement of team practices

Working hours: You’ll work full-time during UK business hours alongside the rest of our team. You’re the kind of person who’s reliable, proactive and takes pride in clean, thoughtful code. You love solving problems without fuss, welcome feedback, and stay calm when requirements shift. Above all, you enjoy collaborating with a friendly team and owning your craft from idea to deployment.

You’ll thrive in this role if you have:

• 4+ years of strong experience in .NET / C#
• Solid React.js skills (component-driven architecture)

Bonus points for:

• Experience with Azure services and DevOps pipelines
• Familiarity with Razor Pages / MVC

• 25 days paid time off + UK public holidays
• 5 days of paid sick leave
• Remote-first culture - work from wherever you’re happiest
• Professional development support
