Car Planet is a fast-growing car supermarket and automotive retail business building and running our own in-house platforms — including Autogrid (our core Dealer Management System), plus supporting systems like Audiofy (call intelligence) and RoutePortal (logistics & routing).
We’re looking for a senior, pragmatic software engineer to inspect, stabilise, and improve live, revenue-critical systems as the business scales. You’ll work hands-on with existing production systems to improve performance, reliability, and maintainability — without disrupting day-to-day operations.
🔹 What You’ll Be Doing
• Take ownership of an existing production codebase
• Identify technical debt, performance bottlenecks, and architectural risks
• Improve system stability, scalability, and maintainability incrementally
• Safely refactor critical areas without disrupting live operations
• Work across multiple internal systems:
• Primary ownership: Autogrid
• Secondary oversight: Audiofy & RoutePortal
• Review code and raise engineering standards
• Partner closely with the CEO, product, and operations teams
• Turn business problems into practical technical solutions
🔹 What We’re Looking For
Essential
✔️ 5+ years professional software development experience
✔️ Proven experience working on live production systems
✔️ Full-stack JavaScript / TypeScript (Next.js, Node, APIs, databases)
✔️ Python experience (scripting, services, tooling, data processing)
✔️ Strong refactoring and system-improvement skills
✔️ Comfortable in fast-moving, imperfect environments
✔️ Able to work autonomously with strong judgement on priorities & risk
Highly Desirable
⭐ C# / .NET experience
⭐ Startup or scale-up background
⭐ Technical leadership experience
⭐ Experience across multiple internal products
🔹 The Package
💰 Salary: £40,000 – £60,000 (DOE)
📝 Open to initial contract engagement before permanent hire
Benefits:
• 28 days annual leave (incl. Bank Holidays)
• Company events
• Employee discount
🕘 Working Hours:
Monday – Friday | 09:00 – 18:00
📍 On-site in Enfield
