• Experience working with high-volume operational, IoT or telemetry data would be particularly valuable.

This role would suit an experienced Senior or Lead Data Engineer who can hit the ground running, work autonomously and confidently challenge existing engineering approaches where needed.

At Mirai, we believe diverse teams build better technology. We’re committed to creating an inclusive recruitment process and encourage applications from people of all backgrounds, experiences and identities.

If this role sounds interesting but you don’t meet every requirement, we’d still encourage you to apply.
