Join Safety io as we revolutionize cloud-based IoT solutions that save lives in hazardous environments. Our South African engineering team works alongside global colleagues in Berlin and the USA to create next-generation connected safety solutions, backed by MSA's 100+ years of market leadership. You'll work in a modern, agile, cross-functional team building cloud applications that power IoT solutions for live workforce monitoring in dangerous areas—your code will literally save lives.

As a Backend Software Developer, you'll build and maintain microservices, data flows, and AWS infrastructure using TypeScript and Node.js. You'll ensure reliability, observability, and performance of production systems, develop Infrastructure as Code with AWS Cloud Formation and Ansible, and contribute to CI/CD pipelines and internal tooling.

We're looking for someone with a Bachelor's degree in Engineering or Computer Science, 5+ years of experience, strong programming skills in JavaScript/TypeScript/Node.js, understanding of cloud fundamentals (ideally AWS), solid knowledge of REST APIs, microservice architecture, serverless, and PostgreSQL, plus expertise in various automation testing types.

You'll need strong communication skills, time management, decision-making abilities, and the drive to challenge the status quo.

We offer a competitive salary, hybrid working model (3 days in office), 21 days' vacation, and the unique combination of a startup environment with the security of a global market leader.

You'll enjoy meaningful projects that make a real difference, a modern agile culture that embraces diversity and knowledge sharing, access to conferences and training tools, modern office spaces in Johannesburg or Cape Town, and regular social events. This role includes occasional local and international travel opportunities to our Berlin office.
