- Lead Cloud Engineer
- Job Description
- A well-known British motoring company are looking for a Cloud & Security Platform Lead to join them in what is a brand new position for the company. There’s a lot of scope here for you to have a real effect on their cloud platform. Joining a team of 10, you’d be responsible for leading the strategy (and setting standards across the department) behind their cloud and security technology, with a focus on working with AWS, which is their cloud provider of choice. What experience do I need? You’ll need a really in-depth knowledge of AWS (as well as the relevant services, such as compute, storage, networking, database and most important serverless, as this what they work on) as you’ll be working with it day to day. A wide knowledge of IaC tools like Terraform and CloudFormation is needed as there are a lot of cloud deployments to automate. You’ll also need prior hands on experience with containerisation technologies such as Docker and Kubernetes, as well as cloud-native application development and microservices architecture. Security, from both a hands on and compliance aspect, is also a key part of the role. You’ll need an in-depth knowledge of the principles and practices here, including but not exclusive to firewalls, intrusion detection/prevention systems, encryption and endpoint protection. On the compliance perspective you’ll need an understanding of security standards and frameworks such as ISO27001, NIST and GDPR. What will I be doing? Key to this role is having the capability to come in and really set the strategy for the department, as that is what they’re missing in the current team. It’s very much a strategic role where you’ll be tasked with creating a roadmap around both cloud and security, and then rolling this out. Think the standard tasks for this type of role, such as ensuring the team follow standards on security and cloud, designing and deploying cloud infrastructure and fostering a real positive culture of collaboration and innovation. What’s in it for me? They’re offering up to £120K for the role as well as a wide range of benefits. These include an annual bonus of up to 20%, a £5K cash-car allowance (which you’ll get even if you don’t have a car!), 7% pension and private medical insurance. They ask you to come into the office twice a week (they’ve locations in London and Basingstoke) and there will be travel once or twice a month to the location you’re not in. This will of course be expensed. What does the interview process look like? They’re looking to move quickly on this (in their words; they needed someone last week) so are doing 3 short stages. The first is a 30/45 minute conversation with the Head of Technology, which will be followed by a 75 minute technical deep dive. If that goes well then the last stage will be to meet the wider team for 45 minutes. This is a chance to get to know both them and the company culture a little better.
