About the Role

Do you remember the excitement of building your first backend service that just worked — processing data, connecting systems, and powering real applications? We want to give our customers that same seamless feeling when they start and run their business with doola.

We’re building the infrastructure that allows business owners to launch their company effortlessly, keep it compliant, and manage operations without friction. The services and tools exist; now we need a skilled backend engineer to help us bring it all together into scalable, secure, and maintainable systems.

Our stack includes Java (Spring Boot), Node.js middleware, MySQL, MongoDB, PostgreSQL, AWS, and Terraform. You’ll work closely with product, frontend, and infrastructure teams to deliver impactful solutions.

• Design, build, and maintain scalable backend services and APIs for both external customers and internal systems, within our microservices architecture.
• Integrate backend systems with databases (MySQL, MongoDB, PostgreSQL) and optimize data storage and retrieval.
• Develop Node.js middleware to bridge backend services with frontend applications.
• Collaborate with frontend engineers, product managers, and designers to deliver end-to-end features.
• Implement and uphold security best practices to protect sensitive customer and financial data.
• Deploy, monitor, and troubleshoot services in AWS environments (EC2, RDS, S3, Lambda, etc.).
• Write automated tests (unit, integration) to ensure code reliability and maintainability.
• Maintain high coding standards with clean, modular, and well-documented code.

Hands-on experience with MySQL and PostgreSQL/MongoDB. Experience designing and integrating RESTful APIs (GraphQL experience a plus). Familiarity with AWS (EC2, RDS, S3; Lambda).
• Proficiency: Strong understanding of backend architecture, database optimization, and distributed systems. Skilled in writing clean, maintainable, and testable code. Comfortable debugging complex backend issues and identifying performance bottlenecks.
• Collaboration: Ability to work effectively with cross-functional teams in a remote-first environment. Strong communication skills to articulate technical concepts to both technical and non-technical stakeholders.
• Flexibility: Comfortable working in EU or US time zones and flexible with adjusting working hours as needed to accommodate team meetings and collaboration across different time zones.
• Quality Code: You write clean, scalable, and well-tested back-end systems with strict adherence to coding standards, ensuring performance, security, and maintainability.

• Experience with Docker and containerized application development.
• Familiarity with infrastructure-as-code tools (Terraform, CloudFormation).
• AWS certifications or equivalent cloud experience.
• Startup or high-growth company experience.
• Knowledge of messaging systems or event-driven architecture (e.g., Kafka, RabbitMQ).
