Senior PHP Engineer – OneTouch Health

Location: Galway, Ireland (Hybrid options)

Reports to: Engineering Manager

About Our Company – OneTouch Health

OneTouch Health is a leading SaaS provider for the health and social care sector, offering an integrated care management platform that connects providers, caregivers, and families. Following a period of rapid growth and acquisitions across the UK, Ireland, and Australia, OneTouch Health is entering a new phase of platform integration and innovation. We’re building a single, unified platform that transforms how care is delivered and managed.

Role Overview

OneTouch is seeking a senior PHP software engineer to build and modernize customer-critical capabilities in the OneTouch platform by incrementally migrating legacy PHP into well-structured Laravel services, improving reliability, performance, and maintainability in a multi-tenant environment. In addition, this role will be responsible for feature development and working as a lead developer for a full stack scrum team focused on specific platform functions.

Key Responsibilities

• Deliver features in Laravel while progressively extracting/rewriting legacy PHP into modular components.
• Refactor legacy code: introduce clear boundaries, reusable domain modules, and consistent patterns.
• Improve data access: reduce over-fetching, optimize slow queries, and safely work around/through legacy schemas and stored procedures.
• Strengthen multi-tenant safety: enforce tenant isolation, permissions, auditability, and secure defaults.
• Raise engineering quality: tests where it matters (unit/integration), code reviews, CI discipline, pragmatic documentation.
• Partner with product, QA, and ops to ship predictably and reduce incidents/regressions.

Qualifications & Experience

• Strong PHP and Laravel experience (real production delivery).
• Practical experience modernising legacy systems (strangler pattern, incremental refactor, migrations without “big bang” rewrites).
• Solid SQL skills (performance tuning, query plans, indexes basics, working with ugly schemas).
• Testing mindset and ability to improve quality without slowing delivery.
• Clear communicator; comfortable working in a PE-backed, outcome-driven environment.
• Experience with multi-tenant SaaS patterns and data partitioning strategies.
• Observability mindset (logging, metrics, tracing) and production debugging.
• API design (REST), auth patterns (OAuth/JWT), and background jobs/queues.
• AWS experience (or similar cloud), containerisation, CI/CD familiarity.

Benefits – What will you get in return?

• High-impact role in a PE-backed healthcare SaaS business
• Work on software that directly improves care quality and safety
• Collaborative, ownership-driven engineering culture
• Hybrid working
• Competitive compensation
• Pension, health insurance, income protection
• Generous annual leave
• Active sports & social programme
