What a Site Reliability Engineer does on a managed DevOps team.

Skills and scope are agreed before delivery starts, so the first sprint is productive rather than a ramp-up month. The work runs to the same backlog, the same repositories and the same definition of done as your own team's.

Site Reliability Engineer skills and technology we assign for

  • Defining service level objectives and error budgets that product and engineering both accept.

  • Building observability so an incident is diagnosed from data rather than guesswork.

  • Incident response, on-call process and blameless postmortems that change something.

  • Capacity planning against growth so scaling is a decision rather than an emergency.

  • Running game days to test whether the runbooks actually work under pressure.

Seniority levels we assign.

Senior and principal. SRE is a judgement role, and junior SRE tends to produce dashboards rather than reliability. Seniority is one of the inputs behind the committed monthly capacity written into your agreement.

When a Site Reliability Engineer is the right assignment.

Makes sense once downtime has a measurable commercial cost. On an ongoing roadmap this role is most often assigned alongside a DevOps Engineer or a Cloud Engineer. All 4 roles in this service line can sit on the same agreement, and capacity moves between them at the monthly cycle rather than requiring a new contract. This capacity is assigned under DevOps as a service rather than sold as a separate engagement.

Questions about assigning a Site Reliability Engineer.

Do we need an SRE if we already have DevOps?

Not always. SRE makes sense once downtime has a measurable commercial cost and someone needs to own that number.

Will the SRE take on-call?

Within agreed hours, yes. Thai working hours cover a European afternoon, and the arrangement is set out in the agreement.
