• Lead the design and development of backend services using Node.js within a microservices architecture.
• Take ownership of backend system architecture, ensuring scalability, reliability, and best-in-class engineering practices.
• Mentor and lead a talented backend team of three engineers (mid-senior level), conducting code reviews and enforcing high standards of test coverage.
• Collaborate closely with project management, product teams, and business stakeholders to translate requirements into robust technical solutions.
• Ensure system performance and security remain at the forefront of development practices.
• Play a hands-on role, with approximately 80% of your time spent coding and 20% on leadership and mentoring.

• Experience with ElasticSearch highly desirable.
• Minimum 5 years in software development, with at least 2 years in a leadership or mentoring role.
• Experience in financial services compliance is a plus but not essential.
• Strong knowledge of design patterns, coding standards, and best practices.
• Excellent communication and collaboration skills, with the ability to engage both technical and non-technical stakeholders.
Team Environment:
You'll be joining a collaborative, multi-disciplinary team that includes frontend, app development (Flutter), DevOps, and QA specialists. The backend team is seeking strong architectural leadership, making this a pivotal role with high visibility and real influence on future technical direction.
