Role overview

Join a world-class engineering team building unique time travel debugging technology used by global tech giants. As a Platform Engineer, you will own the infrastructure that powers the development, testing, and release of complex systems software. You will work across the full stack, from CI/CD pipelines to AWS cloud infrastructure and observability.

Software

Undo is a software debugging company based in Cambridge, UK, specializing in time travel debugging technology for Linux software. Their tools, including UDB and LiveRecorder, enable developers to record, replay, and debug complex C/C++, Rust, Go, Java, and Kotlin applications, particularly in large-scale codebases for networking, security, financial services, databases, and simulation systems, reducing debug times and improving productivity.

What you will do

  • Deploy and maintain critical internal systems including Jenkins CI pipelines, artifact repositories, and product delivery systems using Ansible and Terraform.
  • Build and manage custom machine images for testing, container images for builds, and automated laptop environments for the engineering team.
  • Proactively implement observability and monitoring frameworks to detect service issues and ensure high availability across the AWS cloud environment.

Who this is a fit for

  • Has 2-5 years of experience in Platform, DevOps, or Site Reliability Engineering with a strong focus on Linux environments.
  • Possesses professional Python development skills and hands-on experience with Infrastructure as Code (IaC) tools like Terraform and Ansible.
  • Demonstrates a deep understanding of CI/CD workflows, networking diagnostics, and the ability to manage complex technical trade-offs in a fast-paced environment.

Why this role is remarkable

  • Work on truly unique "time travel" technology that allows developers to record and rewind program execution, a product with no direct market competitors.
  • Join a profitable, Series B funded company ($20M raised) with a small, elite engineering culture where you can make a visible impact on the entire platform.
  • Solve fascinating low-level systems problems at the intersection of Linux operating systems, cloud infrastructure, and high-performance developer tools.
