You will develop backend services in Node.js and support/improve existing 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 the 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
• 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)
• Solid experience designing and integrating RESTful APIs
• 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)
• 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)
• Familiarity with infrastructure as code tools (e.g., Terraform, CloudFormation) is a plus
• Proficient in written and verbal English communication
Personal Attributes
