Job details:
Responsibilities
- Design and develop scalable Laravel backend services (PHP 8.x, Laravel 10/11).
- Build inventory & reservation flows (seat/zone inventory, hold windows, anti-oversell logic).
- Implement and maintain payment workflows (webhooks, reconciliation, refunds, idempotency).
- Own performance, reliability, and observability: caching, queues, metrics, logs, alerts.
- Model and optimize databases for high read/write (indexes, transactions, locking, query tuning).
- Collaborate with front-end/devops and participate in architecture decisions and code reviews.
- Write automated tests (unit/integration), ensure secure coding practices.
Must-have skills (non-negotiable for this project)
- Strong Laravel backend expertise (service layer, events/listeners, queues, jobs, policies).
- Deep understanding of transactions, locking, concurrency, and preventing race conditions.
- Practical experience with Redis (cache + locks + rate limiting) and queues (Horizon).
- Solid database skills (MySQL/Postgres): indexing, query optimization, schema design.
- Strong API design: REST best practices, validation, versioning, auth (JWT/OAuth/Sanctum).
- Clean code, testing discipline, Git workflows, strong debugging skills.
Strongly preferred (big plus for ticketing)
- Real-time features: WebSockets (Laravel Echo/Pusher/Soketi) or SSE.
- Payments: Stripe integrations with webhook reliability.
- Search / filtering at scale (Meilisearch/Elastic), CDN usage, image/ticket PDF generation.
- Experience with high-traffic launches / flash sales and traffic spikes.
- Familiarity with microservices or modular monolith architecture.
Nice to have
- Experience delivering AI/ML-adjacent projects (not required).
- DevOps comfort: Docker, CI/CD, basic AWS/GCP knowledge.
What success looks like (first 60–90 days)
- Stabilize/ship core flows: Reserve → Pay → Confirm → Issue ticket.
- Reduce oversells to ~0 via correct locking/idempotency.
- Improve p95 latency and checkout reliability under simulated spike load.
