Job Description

More about our mission.

About the role

We are looking for a Senior Software Engineer to join our Reliability Engineering team at Wise. You will work cross-functionally with software engineering teams across the business, identifying and implementing reliability improvements to our most important business services.

Our team's mission: Enhance the reliability, performance, and compliance of Wise products for customers. Bridge the gap between Product and Platform through collaboration, hands-on contribution, and co-ordinating org-wide efforts.

How we work

We operate on a strong belief in automation and reusable design. We’re looking for people who can step back and think holistically about the ecosystem, design scalable solutions, and follow through on implementation, drawing on the resources across the rest of the Platform tribe.

As Wise scales, the reliability expectations for our products continue to increase. To sustain the growth, we must continuously iterate on the services we run, with a focus on availability and customer experience. We’re looking for an engineer with relevant expertise who can analyse complex requirements and deliver simple solutions to help product teams achieve our mission with speed and confidence.

What will you be working on?

  • Identify opportunities to optimise the performance of our critical backend microservices, by implementing and improving the common libraries used by teams across Wise.
  • Develop and implement org-wide, resilient strategies in code, to address challenges in capacity, autoscaling, resiliency, performance and redundancy.
  • Deep-dive with teams into their services, suggest best practices, and implement changes to improve reliability.

What do you need?

We are fully aware that it is uncommon for a candidate to have all skills required and we fully support everyone in learning new skills with us. So if you have some of those listed below and are eager to learn more we do want to hear from you!

  • A product engineering background, and are looking to have a big impact.
  • Strong collaboration skills, an ability to jump into projects with limited context and be enthusiastic about influencing how teams prioritise reliability.
  • Strong experience working with microservices in a Kubernetes, cloud-based architecture.
  • Hands-on Software Engineering experience (Java or other backend languages) - you will be contributing to the Wise product and applying reliability best practices (development, resiliency patterns, observability).
  • Hands-on experience with troubleshooting Application, Database, Data related issues.
  • Strong prioritisation skills and effective time management.
