Junior Platform Engineer

The role

Natterbox runs a cloud communications platform that our customers depend on every day. As a Junior Platform Engineer, you will join the Platform team to help keep it reliable, secure and well understood. You will work alongside senior engineers, learn how our platform operates, and build automation that reduces manual effort.

This is a strong step for someone with early cloud or infrastructure experience who wants to grow into a platform or site reliability career. We expect you to use AI tools in your daily work, for example to troubleshoot faster, write and review scripts, and keep runbooks current.

What you’ll do

• Support the day-to-day running of our AWS infrastructure under the guidance of senior engineers.
• Monitor system health, investigate alerts and help resolve incidents.
• Take part in our on-call rota, initially as secondary alongside a senior engineer, moving to primary once you are ready.
• Own the Staging environment, keeping it representative of Production so that we catch issues before customers do.
• Write scripts and infrastructure as code to automate repetitive operational tasks.
• Contribute to infrastructure migration and modernisation work as the platform evolves.
• Apply security best practice and help evidence compliance with ISO 27001 and other regulatory frameworks.
• Document procedures, runbooks and configurations so that knowledge is shared and not held by one person.
• Respond to requests from other teams where they relate to the platform, prioritised through the Platform team’s queue.

A Note on Using AI in Your Application

At Natterbox, we love modern technology and actively encourage using generative AI tools like ChatGPT or GitHub Copilot in our daily engineering work to troubleshoot faster and build automation. We certainly don’t mind if you use AI to help refine your CV or check your application.

However, please don’t use AI to present yourself as someone you are not. We are hiring an authentic early-career engineer with real curiosity, honest learning stumbles, and genuine potential and not an artificial, flawless persona.

Please ensure that all application answers and technical summaries are written in your own words and reflect your actual hands-on experience. Most importantly, AI tools must not be used to generate answers during live interview stages or technical assessments. We want to get to know you, how you think through problems, and how we can support your growth as a platform engineer.
