Job description

An enterprise software consultancy in Johannesburg needs a Senior Mobile Software Engineer to work on enterprise-grade mobile applications. You’re someone who has mastered mobile: a deep understanding of the ecosystems, the best practices and the interface design that separates a good app from a tolerated one.

You’d join a community of highly skilled engineers, and the role carries real seniority — mentoring, influencing how the team works, and setting the bar others work to.

Delivery

• Build high-quality mobile applications used at genuine scale by large, established organisations
• Raise the quality of what ships, using containerisation and continuous integration to tighten the release process
• Work across the lifecycle — system design, analysis, scoping and estimation
• Research current technologies and put them to use on your project

People and customers

• Mentor and grow other engineers
• Influence change within the team and drive a collaborative culture
• Coordinate with teams to meet quality standards and timelines
• Build strong client relationships, understand the business need and manage expectations
• Identify opportunities for service improvement and strategic alignment
• Ensure compliance with data security and industry regulation

What you’ll need

• A bachelor’s degree in IT, Engineering or another of the sciences
• At least 6 years as a software engineer in an enterprise environment
• Experience in a delivery team working alongside other disciplines to ship a product
• A solid grasp of software engineering fundamentals, and commitment to clean code and best practice
• Proficiency, ideally mastery, across a range of technologies, and the agility to pick up new ones
• The ability to architect and structure a discrete piece of work end to end
• Experience interfacing with REST APIs
• Experience deploying to the app stores

The stacks in use

• Languages: Kotlin, Java and Swift
• Frameworks: Flutter, React Native, Ionic/Capacitor
• Databases: Room and Firebase

What you’ll get

• Medical aid, provident fund and insurance benefits
• A wellness programme with professional support across all aspects of wellbeing
• Hands-on support from leadership, with continuous feedback and regular performance reviews
• Large-scale enterprise work, and structured training that runs from technical depth through to leadership
