About the Senior Backend Developer (PHP) Position

We are looking for a Senior/Lead Backend Developer (PHP) to take ownership of backend development for web platforms serving our global clients. This is a hands-on role with technical leadership scope — you will design the architecture, write production code, and be the technical point of contact for the client.

You will work in a small, senior team with direct client exposure. Requirements come to you unfiltered, which means you will shape the solution rather than just implement a spec. As Senior/Lead, you will also set engineering standards, review code, and mentor the engineers around you as the team grows.

Responsibilities

Design, build, and maintain scalable backend services and APIs in PHP
Own technical decisions: architecture, data modelling, integration design, and technical trade-offs
Translate business requirements into technical specifications, and raise concerns early when requirements are unclear or risky
Lead code reviews and set engineering standards across the team
Mentor mid-level and junior engineers; grow the team's technical capability
Work directly with clients and product stakeholders in English - requirement sessions, demos, design walkthroughs, and status reporting
Investigate and resolve production issues; own performance, reliability, and security of the services you build
Collaborate with Frontend, QA, DevOps, and Product to deliver features end to end

Requirements

5+ years of professional PHP development
Strong command of modern PHP (8.x) and at least one major framework - Laravel or Symfony
Solid experience designing and consuming RESTful APIs, and integrating third-party systems
Strong relational database skills (MySQL/PostgreSQL): schema design, query optimisation, indexing
Practical experience with caching (Redis), queues/async processing, and application performance tuning
Comfortable with Git, CI/CD pipelines, Docker, and Agile/Scrum delivery
Proven experience leading or mentoring engineers and owning technical direction on a project
Good at English communication

Nice to Have

Experience with microservices or event-driven architecture (Kafka, RabbitMQ)
AWS experience (EC2/ECS, RDS, S3, Lambda) - a strong plus
Frontend familiarity (Vue.js, React) for full-stack collaboration
Experience working in an outsourcing / client-services model with US or EU clients
Exposure to Golang, Node.js, or Python as a secondary language
Test automation experience (PHPUnit, Pest)

Tech Stack

Language: PHP 8.x
Framework: Laravel or Symfony
API: RESTful APIs, GraphQL
Database: MySQL / PostgreSQL
Caching: Redis
CI/CD: GitHub Actions / GitLab CI, Docker
Async / Queue: Laravel Queue, RabbitMQ / AWS SQS
