Senior Software Engineer – Core Platform

Company: Orbis Group
Apply for the Senior Software Engineer – Core Platform
Location: Greater London
Job Description:

I’m working with a fast growing product-focused company building foundational technology used by engineering teams globally.

This isn’t feature-heavy product work. It’s focused on the underlying components that systems rely on, where stability, reliability, and getting things right really matters.

You’d be joining a core team responsible for maintaining and evolving these components, while also working closely with users to solve real-world issues.

Why this is interesting:

  • Working on core technology rather than surface-level features
  • Real engineering problem solving, not just delivery
  • Blend of development, debugging, and user-facing problem solving
  • High ownership in a small, experienced team
  • Direct visibility of how your work is used in production

What you’ll be doing:

  • Developing and maintaining core backend components
  • Investigating issues and improving system reliability
  • Collaborating on integrations and enhancements
  • Supporting users and resolving technical challenges
  • Building internal tooling where needed

What they’re looking for:

  • Strong backend engineering fundamentals (Java experience ideal)
  • Experience working on complex systems
  • Comfortable working in Linux environments
  • Engineers who enjoy understanding how things work under the hood
  • Self-sufficient, proactive mindset
  • Remote-first, globally distributed team
  • High trust, low ego engineering culture
  • Strong focus on quality and continuous improvement
