Senior Software Engineer (C# / .Net)

• You’ll join a small, high-trust team where ownership is expected, curiosity is encouraged, and outcomes matter more than activity
• This is not a ticket-factory role: you’ll be expected to think critically, challenge assumptions, design robust solutions, and take responsibility for their long-term success
• You’ll work across backend services, distributed systems and frontend integrations, with a strong focus on correctness, maintainability and architectural clarity
• You’ll also use AI-assisted development tools responsibly, understanding that speed only matters when paired with strong design, testing and review discipline
• Operate with high ownership in a low-process environment
• Proactively look for what can be improved rather than waiting for direction
• Value correctness, clarity and maintainability over “it just works”
• Work outside strict role boundaries when needed, without feeding burnout culture
• Communicate technical decisions clearly and push back constructively when required

Benefits

• Unlimited holiday: We measure outputs (work produced) rather than inputs (days worked per year). We don’t track how many hours that you’re logged on each day, so we won’t track your holiday either.

• Flexible working: Everyone at LineTen is a high performer who is perfectly capable of managing their time effectively. Therefore, we give you a lot of freedom and flexibility to manage your working week. Need to pick up the kids from school? Want a mid-afternoon pilates break? Does the dog need a walk? No problem!
• Udemy accounts: Everyone gets access to a Udemy account for continuous learning on almost any topic you can think of

• Travel: At LineTen we are a remote-first team, which means you have a lot of freedom to live your digital nomad dreams!
