Job Description:

As a product-driven company founded by engineers, we know the value of a great engineering culture, and we’re looking for a Principal DevOps Engineer to join a team built from the ground up on trust, teamwork and tight feedback loops.

You’ll work collaboratively using a modern tech stack (Kubernetes, AWS, Terraform, .NET) to help Gearset run a scalable, secure and reliable service, and enable development of the solution to scale with the rapid growth of the company.

We live by our core values, which aren’t just nice words – they guide us through day-to-day challenges and are the foundation of how we work together. Our pragmatic approach has allowed us to maintain the ability to release updates to our application multiple times a day, even as we add new features to the product and expand our global footprint.

WHAT’S THE OPPORTUNITY FOR A PRINCIPAL DEVOPS ENGINEER AT GEARSET?

  • – Be an integral part of building and supporting our multi-tenant infrastructure, running in multiple regions across the globe, all powered by AWS and Kubernetes.
  • – Enjoy high autonomy and real ownership to help shape and drive our technical roadmap based on where you see the greatest value and engineering impact.
  • – Work on critical production infrastructure used by thousands of teams and help us to maintain our excellent reputation for delivering a service with minimal downtime, even when we’re making complex changes behind the scenes.
  • – Get involved in building and maintaining the automation that allows our engineering team to safely release updates to our product multiple times per day.
  • – Continuously improve the security of our infrastructure and our ability to detect and respond to issues.
  • – Collaborate with and support teams across the organisation, including developers, designers, data engineers, marketers and salespeople, to make a real difference to our customers.

WHAT YOU’LL ACHIEVE

  • – Operate and evolve our infrastructure to help scale for an ever-growing user base, and support a team developing our increasingly sophisticated SaaS
  • – Work closely with developers to ensure our application and infrastructure work in harmony, using your expertise and rigour to make sure changes are rolled out safely and smoothly
  • – Lead initiatives to fortify our security measures and keep our customers’ data secure
  • – Work with teams across Gearset to deliver infrastructure that supports their impactful work
  • – Contribute your experience and insight to a collaborative, self-directed team with autonomy over its roadmap and practices

ABOUT YOU

  • – Have in-depth practical experience working on AWS (VPC networking and security, IAM, EC2, Postgres RDS, S3, EKS)
  • – Have experience running production-level services in Kubernetes and managing and maintaining clusters
  • – Practical experience automating the management of infrastructure with Terraform
  • – Experience in the configuration and running of a CI/CD pipeline
  • – Previous experience supporting the operation of a hosted, multi-tenant SaaS product at scale
  • – Comfortable giving and receiving constructive feedback to make your work even better
  • – Approach your work with pragmatism, prioritising iteration, and delivering value over process and deliberation

GREAT TO HAVES

  • – Experience with .NET/C#
  • – Experience working in an agile development team with a focus on delivering value early
  • – Experience with building observability and alerting into systems

BENEFITS (THE STUFF YOU’D EXPECT!)

  • – This is a full time opportunity, working Monday to Friday with the option of flexible home working (for most of us that looks like 1-2 days a week in the office).
  • – Generous personal development budget for courses, conferences, or whatever is useful to your professional development in the role of up to £1500 per year
  • – Top end hardware provided
  • – Opportunity to join our Long Term Incentive Plan
