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.
