Description

We are seeking a Software Engineer to contribute to the design, development, and support of our SaaS platform. You will work on frontend, backend, or full-stack features and collaborate with product managers, designers, and DevOps engineers to deliver functionality for both web and mobile experiences.

• Ensure consistent user experiences across browsers, devices, and operating systems, including accessibility standards.
• Collaborate with cross-functional teams to deliver customer-focused features and enhancements.
• Participate in sprint planning, estimation, and delivery within Agile/Scrum frameworks.
• Support production environments, troubleshoot issues, and join on-call rotations when required.
• Partner with QA and DevOps to ensure high-quality releases and strong CI/CD practices.

Skills, Knowledge & Expertise

Essential:

• 2–5 years of software/application development experience with .NET.
• Proficiency in at least one modern programming language (preferably C#).
• Experience with APIs, backend services, or full-stack applications.
• Familiarity with cloud platforms (preferably Microsoft Azure).
• Strong grasp of RESTful architecture, security, and performance optimization.
• Experience with Git and agile development processes.
• Strong problem-solving, debugging, and collaboration skills.
• Effective communication skills for cross-team work.

Desirable:

• Experience integrating with or supporting mobile apps via backend/APIs.
• Knowledge of mobile app deployment, versioning, or device-level testing
• Familiarity with frontend frameworks (Angular, React, or similar).
• Experience with CI/CD pipelines and containerisation (Docker, GitHub Actions, Azure DevOps)
• Awareness of native mobile development languages (Swift, Kotlin).
