Senior Software Engineer – Systems Improvement & Scale

Job description

We’re Hiring: Senior Software Engineer – Systems Improvement & Scale

Company: Car Planet

Location: Enfield

Full-Time (Open to initial contract trial)

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
