## About the Role

* Most importantly, you have a growth mindset. You bring enthusiasm, empathy, and a genuine desire to learn. Qualities that make you a trusted teammate and an active contributor to a thriving engineering community.
 * You've built and supported complex software systems before, maybe as part of a startup where you wore many hats, or within a larger organisation where reliability and scale were critical. You enjoy the puzzle of connecting technologies and people, translating complexity into clarity.
 * You thrive in collaborative environments: pairing, sharing ideas, and learning from those around you. When faced with ambiguity, your curiosity takes over; you test, learn, and adapt quickly. You're motivated by solving real customer problems, not just writing elegant code.
 * You're comfortable navigating distributed systems and modern infrastructure whether that's working with Kubernetes, cloud platforms, or the CNCF and HashiCorp ecosystems. You have proficiency in Golang and Kubernetes, and one or more languages such as Ruby, Rust, or Python, with a willingness to learn whatever new tools help get the job done. You care deeply about engineering excellence practicing Extreme Programming (XP) techniques such as pairing, TDD, and continuous integration to deliver reliable, maintainable software.

## Description

As a Senior Software Engineer at Syntasso, you'll play a key role in designing, building, and evolving Kratix and Syntasso Kratix Enterprise.

You'll collaborate closely with a small, expert engineering team. Your work will span product contribution, customer collaboration, and hands-on system design. You'll help shape architecture and APIs, improve user experience, and scale Kratix for enterprise environments.

In practice, this means you'll:

 * Design and implement features for Kratix and Kratix Enterprise, primarily in Golang and Kubernetes.
 * Collaborate on architectural decisions that balance innovation, reliability, and usability.
 * Engage directly with customers to understand their platform challenges and ensure SKE solves them.
 * Work across product and engineering to deliver software that drives real impact.
 * Continuously learn, experiment, and help define what great platform engineering looks like.
 * Provide hands-on support to SKE customers, from diagnosing technical issues to shaping solutions that improve their platform outcomes.
