- Operate in a fast paced, high volume environment where change is constant.
- Take ownership of streams of work, from technical design through to production support.
- Contribute to CI/CD pipelines, cloud infrastructure, and overall platform resilience.
Your Skills and Experience
- Strong commercial experience building backend services with Node.js and TypeScript.
- Hands on experience with microservices architectures and API driven systems.
- Background working in high traffic, high change environments such as ecommerce, gaming, hospitality, or similar.

- Comfortable working with both SQL and NoSQL data stores.
- A problem solving mindset with the ability to operate effectively in ambiguous situations.
