Job description

About Us

We are a software team building one of the most trusted and long-standing Access Control Systems, used across government agencies and large enterprises for over 37 years. Our product has continuously evolved, and we are now entering a new era of AI-driven software development, leveraging modern tools and technologies to reshape the future of access control.

We embrace AI tools such as GitHub Copilot, Figma AI, Cursor AI, and pyTesting to accelerate development and improve software quality. Our hardware and software teams work closely together — both using the same modern technology stack to deliver a tightly integrated solution.

Role Overview

We are looking for a Backend Development Team Lead who will take a key role in leading our backend engineering team. The ideal candidate should have deep technical expertise, strong leadership, and the ability to drive quality and innovation across the full development lifecycle. The candidate will report to Head of Application.

You will play a critical role in understanding our end-to-end system, ensuring backend reliability, and introducing modern workflow automation into our product — enabling dynamic event-driven operations (e.g., alarm-triggered workflows).

Key Responsibilities

• Lead and mentor the backend development team to deliver high-quality, scalable software.
• Oversee system architecture, code quality, and integration with frontend, hardware, and cloud systems.
• Work closely with the testing, DevOps, and hardware teams to ensure end-to-end reliability.
• Design and implement backend services using modern .NET Core and C# technologies.
• Manage data persistence, high availability, and clustering using MSSQL and Redis.
• Integrate asynchronous communication systems using RabbitMQ.
• Deploy and manage services on Docker, Kubernetes, and cloud environments (Azure / AWS).
• Enhance the system with workflow capabilities — enabling configurable event-based automation.
• Take ownership of the overall software quality and contribute to continuous testing improvements.
• Foster open communication, collaboration, and knowledge sharing across the team.

Required Skills

• Strong expertise in .NET Core and C# backend development.
• Experience with MSSQL database cluster, RabbitMQ, Redis Cache, and IIS Server.
• Familiarity with Docker, Linux, Windows Server, and Kubernetes environments.
• Understanding of cloud platforms such as Azure or AWS.
• Excellent communication and leadership skills — able to coordinate with multiple teams.
• Strong focus on software testing, code quality, and system reliability and scalability

Nice to Have

• Experience with React or other modern frontend frameworks.
• Knowledge of workflow engines or event-driven architectures
• Familiarity with AI-assisted development tools and DevOps automation.

We Emphasize Three Core Areas

• Deep Software Knowledge
• Strong Testing Capability
• Excellent Communication and Team Leadership
