PHP engineer

Lyser is a management-owned, Copenhagen-based company building two B2B SaaS products for HR teams in large enterprises. We have no VC influence, operate with positive cash flow, and have been in active operation for over 5 years. This is a stable business focused on long-term product quality rather than growth-at-all-costs.

We are a tiny, fully remote team. Engineering is distributed, all collaboration happens via Microsoft Teams, and we value autonomy, trust and clear communication over process.

We’re looking for a Senior PHP Engineer who is comfortable owning production systems and wants hands-on experience building LLM-powered features that are used by real customers.

• Livewire, Filament and AlpineJS (backend-powered, admin-heavy, data-driven UIs)

• MySQL, Redis

• Queues, background jobs and scheduled tasks

• Design, implement, and maintain backend-heavy features in Laravel

• Build and operate LLM-powered workflows in production

• Integrate third-party LLM APIs and internal models

• Make architectural decisions around performance, reliability, and maintainability

• Improve existing code where it makes sense (pragmatic refactoring)

• Own features end-to-end: requirements -> implementation -> production -> iteration

• Work directly with the Head of Engineering and management

Requirements

• Several years of production Laravel experience

• Writing clean, testable, maintainable PHP

• Understanding architectural trade-offs and explaining them clearly

• Working with asynchronous systems (queues, retries, failures)

• Debugging and operating real production systems

Basic knowledge of JavaScript and JS frameworks

• Clear communication in written and spoken English

Working time overlap with Central European Time (Copenhagen)

We offer

• 100% Remote work Full-time (or from our office in Copenhagen, Denmark)

• Flexible working time

• 37 hours work week

• 5 weeks paid vacation + public holidays

• Paid sick leave

• Scandinavian working culture

• Stable, profitable, management-owned product company with no VC influence

• High ownership and direct impact on product direction
