Senior Backend Developer (PHP / Laravel)
VANTREXIS is an engineering agency that builds dedicated remote teams for high-growth SaaS companies in the US, UK, and EU. We are looking for a Senior Backend Engineer to develop new features in a complex, integration-heavy product environment. The Role You will join a team where AI-augmented development (** Cursor, Claude, Copilot**) is a daily standard, not a bonus. Your focus will be on delivering clean, typed code within established architectural patterns - and raising the quality bar as you go. Tech Stack Core: PHP 8.2 + Laravel 12. Database: MySQL 8 + Redis. ORM: Eloquent. Auth: Laravel Passport (OAuth 2.0), Spatie Permission (RBAC). Queue: Laravel Queue with multiple named workers. Cloud: AWS S3, SES, SNS. Payments: Mollie / Stripe. Real-time: Pusher, Firebase FCM. Testing: PHPUnit 11. What You'll Do Build & Architect: Deliver new API endpoints following the Controller → Service → Repository pattern. Ownership: Take full responsibility for features from analysis to production deployment. Quality First: Write feature tests alongside every new feature to raise current coverage. Integrate: Extend and maintain external integrations (Mollie, AWS, Firebase, healthcare APIs). Proactive Improvement: Identify architectural bottlenecks and edge cases before they become problems. Requirements Expert PHP/Laravel: Deep knowledge of Eloquent, Passport, Policies, Events, and Jobs. RBAC Patterns: Experience with complex authorization flows and company-scoped roles. Database Mastery: MySQL 8 optimization and writing safe, backwards-compatible migrations. Mindset: You think like an owner, not just a task-executor; you communicate risks early. AI-Tooling: Proficiency in using AI-powered tools to maximize engineering efficiency. Testing Culture: A "craftsmanship" approach where untested code is not considered "done". Nice to Have Experience with Mollie or equivalent payment lifecycles. Familiarity with AWS IVS (live streaming) or Pusher. Experience using PHPStan / Larastan for static analysis. An active GitHub profile or technical pet-projects. What We Offer Remote-first: Work from any safe location in Ukraine. Stability: VANTREXIS is an official Diia City resident. Benefits: Paid vacation, sick leaves, and corporate medical insurance. Culture: Flat structure, zero bureaucracy, and a strong engineering community. Growth: Access to Udemy and internal knowledge sharing. Hiring Process HR Screen: Intro call to discuss experience and expectations. Technical Interview: Deep dive into engineering skills and architectural thinking. Final Decision.
