Job description

Software Engineer - PHP, SQL & AI

Fully remote working for candidates based in the UK

Salary £50k to £60k

Build software, improve automation and put AI to practical use.

Stratospherec is recruiting a Software Engineer to join our client's development team in a broad, hands-on role combining software development, AI-powered automation and technical operations.

You will help develop and maintain an established platform built with PHP, MySQL and AWS, delivering improvements that support both customers and colleagues. Alongside using AI for coding, you will investigate technical issues, improve deployment processes and develop automation that makes customer support more effective.

This opportunity would suit a mid-level or recent senior software engineer with strong PHP and SQL skills, sound software engineering fundamentals and experience of using AI to solve practical problems. PHP experience is beneficial but not essential.

There is the career opportunity to work with the Head of Development to grow into the Tech Lead owning the technical development of the platform.

The role

Working closely with the leadership and a small development team, you will take ownership of development tasks from initial investigation through to testing and deployment. You will use existing AI-assisted development tools while applying your own judgement to ensure code is secure, maintainable and reliable.

You will also help improve an existing AI-powered retrieval-augmented generation (RAG) pipeline, bringing relevant information into helpdesk tickets and developing automated response drafting, resolution and escalation where appropriate.

What you will be doing

• Developing and improving software using AI tools: Deliver features, enhancements and bug fixes from Jira tickets, helping clarify requirements and scope technical solutions.
• Maintaining code quality: Review and test both manually written and AI-generated code, building your understanding of the existing platform and maintaining engineering standards.
• Developing support automation: Improve the existing RAG pipeline and introduce practical automation to help the support team investigate and resolve customer issues.
• Working with databases: Write and maintain SQL, manage schema changes and migrations, and support MySQL database integrity and performance.
• Improving deployments: Maintain and enhance CI/CD pipelines, automate repetitive tasks and support reliable software releases.
• Monitoring AWS infrastructure: Develop monitoring and alerting for availability, resource utilisation and performance, helping identify issues early.
• Solving operational challenges: Investigate complex technical problems, support customer implementations and coordinate with external infrastructure specialists when needed.

What we are looking for

• Commercial software engineering experience, ideally at mid-level or above.
• Strong PHP and SQL skills and experience working with relational databases.
• Sound software engineering fundamentals, including maintainable code, testing and debugging.
• Practical experience with deployment processes, CI/CD or development automation.

  Why consider this opportunity?

  This role offers the chance to make a visible contribution across an established software platform, from delivering product improvements to developing AI-powered support tools and improving day-to-day operations.

  You will work closely with the people making technical decisions and have opportunities to improve how software is built, deployed and supported.
