Senior Software Engineer

Senior Software Engineer – Product Development – Reading (Hybrid)

Avanti Recruitment is partnering with a thriving Software company in Reading. We are looking for an expert Product Engineer with very strong OO PHP skills or OO programming in another language and happy to work with PHP.

This role will suit an engineer who thrives on solving customer problems, not chasing the latest tech or buzzwords.

The Senior Software Engineer will take ownership of complex, high-impact product features on a well-established SaaS platform. This is a hands-on engineering role, not a website maintenance job and you’ll be building the logic, architecture, and integrations that power core customer solutions.

The Role

Working within a small specialist backend team, you’ll design, implement, and deliver PHP-based product features and custom solutions. You’ll be involved from requirements capture through to design, build, test, and deployment — with the autonomy to make technical decisions and shape the outcome.

Expect to work on:

• Backend object-oriented PHP (90% raw PHP, minimal frameworks)
• Designing and building integrations with third-party systems via APIs
• Developing background processes, workflow automations, and data handling logic
• Contributing to product evolution with scalable, maintainable architecture
• Occasionally creating supporting UIs for complex functionality

What We’re Looking For

• Deep expertise in object-oriented programming and backend architecture
• Strong understanding of software engineering principles and design patterns
• API design, development, and integration experience
• HTML, CSS, JavaScript
• Solid database knowledge (MySQL preferred)
• Comfortable owning projects end-to-end
• Linux, SaaS platforms, CRM systems

The Package

• £65k to £75k DOE
• 25 days holiday + pension
• Free on-site parking
• Hybrid in Reading

This role will suit an engineer who thrives on solving complex problems, delivering robust backend systems, and having a tangible impact on product direction.
