SRE at Capital On Tap

At Capital On Tap, we run a hybrid embedded SRE model - We aim to work closely with the teams to provide them the best support. As a Site Reliability Engineer (SRE) you will help ensure our platforms are fast, reliable, and scalable. You ’ l l design, build, and monitor systems, preventing issues before they happen.

XP, the engineering group you will be embedded into, is the platform group that builds the foundations the rest of our engineers rely on: the shared UI frameworks for web and mobile, the backend-for-frontend layer, and the internal developer platform and shared backend libraries beneath them. Our job is to make it fast and safe for product teams to ship great features, by owning the architecture and paved paths they build on top of.

What you ’ l l be doing

Manage and automate resources in Azure, Datadog, NGINX & Cloudflare.
Develop, deploy and monitor Kubernetes and Serverless resources.
Build, manage, and evolve IAC using Terraform, Helm and Go CRDs.

Design and maintain comprehensive monitoring and alerting strategies using Datadog.
Getting involved in new application architecture & design processes.
Designing solutions to reduce toil, automate repetitive tasks and streamline workflows to reduce manual work and boost team productivity.
Creating SLIs and SLOs; increasing application visibility
Align with the Product team on SLAs and core service objectives
Collaborating with core foundational teams to build and maintain reusable, automated solutions.
Optimising CI/CD pipelines and developer workflows using Azure DevOps, Github, Octopus Deploy, MirrorD, and Flux.
Leading incident response; taking an active part in communications, investigations, remediation and post-mortems to protect the customer experience.

Our Values & Culture

Just Pilot: We never settle for “ g ood enough ” . We pilot new ideas fast, ask questions to figure it out, and scale quickly.
Why Not Today? Fast is as slow as we go - speed and simplicity gives us a competitive advantage.
Be a Buddy: We tap in from day one to help the team, we do the right thing even if it ’ s hard.
Owners and Dates: We don ’ t chase people. If you own a task and agree to a date, the expectation is that it gets done.
Feedback: We want our employees to flourish, so we regularly provide direct and constructive feedback.

What are we looking for

Experience managing public cloud environments.
Proficient in contributing to IaC technologies involving expertise in writing, managing, and optimising infrastructure with tools such as Terraform.
Experience using CI/CD tools, building pipelines, templates and troubleshooting.
Proficient with containerisation technologies such as Kubernetes and Docker.
Experience building and deploying frontend applications with tools such as CodeMagic.

Great Work Deserves Great Perks

We try not to take ourselves too seriously (all the time) so we make sure our office is decked out with a pool table, arcade machine, beer tap, and a couple of office dogs thrown in for good measure.
