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

  • Free lunch in the office

  • 25 days holiday plus bank holidays (with the option to buy an extra 5 each year)

  • Company Pension Plan (matching up to 5%)

  • Bupa health care and dental insurance

  • Enhanced family leave from day 1, including 26 weeks full maternity/adoption pay, OTE-inclusive

  • Bupa Menopause Plan offering specialist consultations and support

  • Life Insurance & critical illness cover

  • Discounted gym membership, as well as a range of health and wellness benefits
