Job Description

A product-led SaaS business is hiring a Senior Back End Engineer to help build and evolve its platform, with a strong focus on modern AI-assisted development workflows.


This is a hands-on role suited to someone who is already leveraging AI engineering tools day to day to improve speed, quality, and output. The environment is TypeScript / JavaScript heavy, with some legacy PHP, so you will be working across both modern and existing systems while helping move the platform forward.


Role: Senior Back End Engineer

Salary: Up to £70,000

Location: Fully remote, UK-based


What you’ll be doing:

  • Building and maintaining backend APIs and services across a modern TS / JS stack
  • Working alongside legacy PHP systems, helping evolve and modernise the platform
  • Using AI engineering tools to accelerate development, debugging and delivery
  • Designing scalable services and clean system boundaries
  • Integrating third-party APIs including AI, analytics and external services
  • Collaborating closely with product and UX teams to shape features early
  • Contributing to architecture decisions and technical direction


What you’ll need:

  • Strong commercial backend engineering experience
  • Solid experience with TypeScript and JavaScript in production environments
  • Experience working with or alongside PHP systems
  • Active, hands-on use of AI engineering tools such as Claude, ChatGPT or similar in your development workflow
  • Strong API development skills and understanding of system design
  • Experience integrating third-party services and APIs
  • Comfortable working in fast-moving product environments


What’s on offer:

  • Salary up to £70,000
  • Fully remote working within the UK
  • Opportunity to work in an AI-forward engineering environment
  • High ownership role with influence on technical direction
  • A modern product environment with ongoing platform evolution


This role would suit an engineer who is already embedding AI into their development workflow and wants to work in a team where that approach is expected, not optional.
