[Hiring] Middle PHP Developer @MacPaw

Role Description

We’re looking for a Strong Middle PHP Engineer to join our team and work on subscription and billing-related functionality within a product environment.

You’ll work with complex business logic, third-party integrations, and existing systems, collaborating closely with product and engineering teams. We’re looking for someone curious, proactive, and responsible who enjoys learning, taking ownership, and improving solutions.

In this role, you will:

• Prevent duplicate subscription charges (idempotency, race conditions, retries, edge cases).
• Add endpoint to change subscription plan via Billing Provider (REST API, validation, error handling).
• Handle webhooks from Billing Provider (signature verification, event mapping, retries, dead-letter / reprocessing).
• Implement subscription lifecycle state management (create/renew/cancel/pause, proration, billing periods) + persist changes in PostgreSQL.
• Add/adjust database schema & migrations for billing/subscription entities, write and optimize related SQL queries/indexes.
• Integrate async processing for billing events via RabbitMQ (producers/consumers, monitoring, failure handling).
• Add tests + basic observability: unit/integration tests for billing flows, logging/metrics/alerts for critical payment events; verify Docker/K8s-ready deployment config where needed.

Qualifications

• 3+ years of hands-on experience with PHP and strong knowledge of PHP fundamentals (OOP, namespaces, Composer).
• Hands-on experience with Symfony (routing, controllers, services, configuration) and integrating third-party bundles/libraries.
• Confident work with PostgreSQL / relational databases: schema design, complex SQL queries, migrations, and performance optimization (indexes, profiling).
• Experience with Docker in development and runtime environments; ability to work with Docker images/containers and Docker Compose locally.
• Experience with RabbitMQ (or similar message queues): pub/sub and work queue patterns, producers/consumers, basic configuration concepts.
• Basic understanding of Kubernetes concepts and common objects (Deployments, Services, ConfigMaps).
• Proficient Git usage and collaboration practices (branching, pull requests, code reviews).
• Solid understanding of RESTful APIs and HTTP protocols; familiarity with microservices patterns.
• Knowledge of software design principles (SOLID, DRY, KISS) and ability to apply them in everyday engineering work.
• Basic testing practices (unit/integration) and awareness of secure coding principles (OWASP).
• At least an Intermediate level of English, comfortable with spoken communication in a work environment, not limited to reading technical documentation.

Requirements

• Go (Golang) and familiarity with common libraries and frameworks.
• Workflow orchestration tools such as Temporal or similar solutions.
• CI/CD pipelines and basic understanding of cloud or infrastructure tooling.
• NoSQL databases and caching solutions (e.g. MongoDB, Redis).
