Back-End Developer

Job Description

Overview of the Role

We are looking for a skilled Backend Developer with experience in Node.js and PHP (Laravel) to join our team. You will work on building and maintaining scalable backend applications and services, contributing to a robust and high-performance infrastructure that powers a seamless user experience across our platforms.

You will develop backend services in Node.js and support/improve existing PHP/Laravel (Nova) systems as needed. You’ll collaborate closely with other engineers, participate in technical discussions, and help evolve our backend architecture and best practices. You will own the performance and stability of mobile backend services: ensure all APIs operate efficiently, proactively identify and resolve issues, drive rapid incident resolution, and be accountable for service reliability, uptime, and seamless integration with mobile applications.

This role is ideal for someone who enjoys clean, maintainable code, API design, and continuous improvement. Experience with distributed systems, microservices, state management, and performance optimization is highly valued. Familiarity with cloud technologies, message brokers (e.g., Kafka), and caching systems (e.g., Redis) is a strong advantage.

This role follows a hybrid approach to working, allowing you to combine working from home with working in our modern offices. You and your manager will agree on the best working pattern that suits both of you. We’ll kit you out to work remotely, but we know that collaboration is key to our success, and spending quality time together helps us stay aligned with our mission.

What you’ll do:  

Develop and maintain scalable backend services and APIs using Node.js and PHP/Laravel (Nova).

Collaborate with developers, DevOps engineers, product owners, and other stakeholders to deliver robust and secure backend solutions

Participate in technical design discussions and continuously improve backend architecture and performance

Design and implement RESTful APIs and integrations, including real-time features (e.g., WebSockets) when needed

Integrate with databases (SQL and NoSQL), message brokers, third-party services, and external APIs

Write clean, reusable, and testable code, Unit tests and help maintain high standards for code quality through reviews

Debug and optimize backend systems for performance, scalability, and security

Maintain technical documentation and API guidelines

Perform related duties as assigned

What you’ll bring: 

5+ years of professional software engineering experience, with strong hands-on in backend development

2+ years of backend experience in either Node.js (typescript) or PHP (Laravel; Laravel is a plus)

Solid experience designing and integrating RESTful APIs (SOAP exposure is a plus).

Strong grasp of backend architecture, scalability, microservices, and API security best practices

Proficiency with Git and collaborative workflows (GitHub/GitLab); familiarity with Agile processes

Experience with testing (unit, integration, end-to-end) using tools such as Jest, Mocha, Supertest, or equivalents

Familiarity with CI/CD pipelines, containerization (Docker), and orchestration (Kubernetes)

Experience with cloud platforms (preferably AWS; GCP/Azure also valued)

Knowledge:

Deep expertise in Node.js + TypeScript (Nest.js a plus) or strong knowledge of PHP (Laravel ecosystem). Both is ideal

Experience optimizing backends for scalability, maintainability, and performance

Good grasp of microservices, distributed systems, and asynchronous processing (queues; Kafka/RabbitMQ)

Understanding of authentication and authorization mechanisms (OAuth2, JWT, OpenID Connect)

Knowledge of relational (PostgreSQL, MySQL) and non-relational (MongoDB, Redis) databases

Proficient with Git and collaborative Git-based workflows. Experience with monorepo setups is a plus

Understanding of security principles for web and API development (e.g., OWASP Top Ten)
