Sand Tech Holdings Limited - Site Reliability Engineer

• 5 to 8 years in platform engineering, cloud infrastructure, DevOps or site reliability, operating production systems that mattered to someone. • 5 to 8 years • Cloud infrastructure, hands on. Azure and AWS. You have provisioned and run production data infrastructure rather than only managing it, with a strong understanding of networking, IAM and secure data handling, and how to design effectively within a client’s existing landscape and governance constraints. • Cloud infrastructure, hands on. • Networking you can reason about under pressure. VPCs and VNets, subnets, security groups, DNS, load balancing, private connectivity, and the patterns for getting services to talk to each other across a customer's internal and external boundaries. • Networking you can reason about under pressure. • Kubernetes and containers. Pods, deployments, services, namespaces. Comfortable in kubectl or any kube-api interface for inspection and troubleshooting. You do not need to have written an operator. • Kubernetes and containers. • Infrastructure as code. You are comfortable with using IaC by default, from the start, with more than one toolchain. Demonstrable experience across one or more of Pulumi, Terragrunt, Terraform, OpenTofu, CDK or equivalents is required. Pulumi is used for Symmetri and experience with it is a strong plus. • Infrastructure as code. • Python for automation. As an organisation with strong data science roots we are strongly biased to python for many coding use cases, so familiarity is important and experience is a plus. • Python for automation. • Change management and branching discipline. Standard git workflows, and the willingness to follow and improve a team's existing strategy rather than your own. • Change management and branching discipline. • Resource planning. Sizing compute, memory and storage against what a customer actually needs and what their environment can actually give you, including when that environment is on premises and finite. • Resource planning. • Incident response. You have been on call. You know the difference between fixing an outage and fixing the cause of one, you are able to run effective root cause analysis processes that result in long term improvements. • Incident response. • Client-facing competence with enterprise IT. You can hold a technical conversation with a customer's infrastructure and security people, be trusted by them, and represent a commitment without over-promising. • Client-facing competence with enterprise IT. • You will not be equally strong across all of these aspects. Strong in most, familiar with the rest, unafraid of learning fast while being aware of and drawing in support for your current limitations. • Public sector, utility or other regulated operational environments, and the security review processes that come with them • Air-gapped, sovereign or disconnected deployments of data-intensive systems • Observability and monitoring stacks, and building the alerting rather than only responding to it • Serving ML models and LLM systems in production, including offline • Location • Location • We are looking to hire on the East Coast in the United States, as this is where the majority of our clients are based. • How we work • How we work • This role has an on-call component and accountability. Real production systems, real operational consequences. • It also has less scaffolding than you might expect. We optimize first to fall in love with our clients' challenges and to deliver impactful solutions. This means you will not always receive neatly scoped work, and part of the job is creating that clarity yourself and sharing it. We are not looking for someone to invent everything from scratch or replicate exactly what they have done in the past either. • We believe in strong opinions, loosely held. We have established patterns and approaches that work, built by teams that have run these environments for years, and the person who succeeds here is one who learns them properly first and then improves them while participating in raising our global standard. • Due to the highly collaborative and internationally distributed nature of our work, successful candidates must be comfortable operating in small teams while contributing to larger, globally coordinated efforts. A strong sense of ownership, self-motivation and discipline in maintaining clear and consistent communication through virtual collaboration tools and video conferencing is essential.
