About Us

Appvia is a specialist cloud and platform engineering consultancy and product house helping organisations build, secure, and scale in the cloud. We work with public and private sector customers to design modern cloud platforms, embed strong engineering practices, and enable teams to deliver software faster and more reliably.

Our focus is on platform engineering, DevOps, automation, and cloud-native delivery, creating foundations that balance developer velocity with security, resilience, and governance.

About the Role

As an AWS Senior Platform Engineer, you will be a key contributor to Appvia’s platform engineering engagements, working hands-on to design, build, and operate secure, scalable AWS platforms.

This role is ideal for an experienced engineer who enjoys solving complex technical problems, working closely with development teams, and contributing to the continuous improvement of cloud platforms and delivery pipelines. You’ll operate within multi-disciplinary teams, supporting both application and platform workloads while helping customers adopt modern DevOps and platform engineering practices.

You’ll be expected to take ownership of technical delivery within your area, contribute to solution design, and support less experienced engineers through mentoring and knowledge sharing.

Interview Process - 4 Stage

1. Discovery conversation with Talent Acquisition
2. Paired technical assessment with an Engineering team member
3. Technical deep dive with Practice Leadership
4. Competency-focused final interview with Engineering Leadership
