Backend Integration Engineer | PHP, Symfony and AI

A fantastic opportunity for an experienced Backend Integration Engineer to join a growing SaaS company whose product depends on reliable connections with external software platforms. This is a hands-on role for someone who has personally built and maintained multiple connectors to other companies’ APIs. You will work primarily with PHP and Symfony, using AI-assisted development tools as part of your everyday engineering workflow.

Location: Fully remote within the UK, although ideally you will be based near London. You must be available to travel to London for occasional team meetings and start work at 8:30 am UK time.

Salary: £55,000 - £70,000 per annum depending on experience. Less senior candidates are likely to be considered around £60,000, with the upper end reserved for those offering broader senior-level experience. Additional paid weekend on-call rota, performance bonus and share options.

Requirements for Backend Integration Engineer:

• Strong hands-on commercial experience developing production systems using PHP and Symfony
  
• Genuine experience personally building and maintaining connectors to multiple external platforms
  
• Experience integrating with other companies’ APIs, rather than primarily developing your own APIs for others to consume
  
• Proven ownership of integrations after launch, including maintaining them when external APIs, schemas, credentials or platform behaviour change
  
• Strong understanding of REST APIs, webhooks, OAuth, rate limiting, retries, idempotency, queues and asynchronous processing
  
• Experience monitoring integrations in production and investigating failures across internal and external systems
  
• Regular use of AI-assisted development tools as part of your day-to-day software engineering work
  
• Ability to work autonomously, make sound technical judgements and progress work without detailed instructions
  
• Experience with automated testing, code quality and CI/CD practices
  
• Some production AWS experience, although extensive infrastructure ownership is no longer required
  
• Evidence of sustained contribution and ownership within at least one organisation
  
• Comfortable committing fully to a permanent, full-time position
  
• Experience within food and beverage technology would be beneficial, although a genuine interest in working within the sector is also welcomed
  
• Must be based in the UK with existing right to work. Visa sponsorship is not available
  

Responsibilities for Backend Integration Engineer:

• Design, build and maintain connectors to multiple external software platforms
  
• Develop integration services using PHP and Symfony
  
• Take integrations through development, testing, launch and ongoing production support
  
• Maintain integrations as partners change their APIs, schemas and authentication requirements
  
• Build adapters and transformation layers between different external systems
  
• Develop reliable workflows using REST APIs, webhooks, queues and asynchronous processing
  
• Monitor live integrations and investigate failures involving both internal and partner systems
  
• Use AI-assisted development tools to support coding, testing, code review and technical analysis
  
• Develop automated tests and strengthen CI/CD quality gates
  
• Contribute to backend platform features and technical architecture
  
• Support the operation of the company’s AWS environment
  
• Take ownership of technical problems and propose appropriate solutions
  
• Participate in a paid weekend on-call rota supporting urgent integration issues
  

What this role offers:

• Ownership of business-critical integrations that sit at the heart of the company’s product
  
• The opportunity to use AI-assisted engineering tools as a core part of everyday development
  
• Excellent scope to influence technical decisions and take on wider responsibility as the company grows
