Senior Site Reliability Engineer

At Build Ops, we’re building a software platform that empowers today’s commercial contractors. From service management to project execution, we’re reimagining how our customers operate. Our team thrives on ambition, innovation, and collaboration – qualities we look for in every new hire.

You will join our cloud infrastructure and reliability engineering team as a Site Reliability Engineer (SRE). Your primary responsibility will be to improve and protect the reliability, performance, and operability of our production systems while helping evolve our AWS‑based infrastructure. We’re looking for someone with a strong SRE mindset, solid software engineering fundamentals, and deep observability expertise who can work effectively in a distributed team environment.

Reporting to the Dev Ops and SRE Manager, this is a hands‑on role where you will influence reliability strategy, build tooling and automation, and contribute directly to day‑to‑day operations in a fast‑moving, industry‑defining company.

What You’ll Do

Drive and refine modern SRE practices across services, including SLIs/SLOs, error budgets, and reliability reviews

Design and maintain end‑to‑end observability (metrics, logs, traces, dashboards, and alerts) so teams can quickly detect, debug, and prevent issues

Partner with product and engineering teams to design reliable services—reviewing architectures, failure modes, rollout strategies, and capacity/latency considerations

Help evolve and operate our AWS infrastructure (networking, compute, data stores) using Infrastructure as Code (Terraform)

Contribute code to services, tooling, and automation (for example, reliability libraries, deployment and incident tooling, health checks)

Define, implement, and iterate on SLIs, SLOs, and error budgets with service owners, and use them to guide reliability work and release decisions

Participate in incident response for infrastructure‑related production issues, including learning‑focused post‑incident reviews and follow‑through on action items

Develop runbooks, safeguards, and automation that reduce manual work, improve time‑to‑diagnosis, and standardize responses to recurring scenarios

Advocate for and implement security and compliance best practices in production environments

Document standards, playbooks, and best practices so reliability improvements scale across teams

Collaborate closely with software engineers, product managers, and other stakeholders to plan and deliver reliability‑focused initiatives

What We Look For

5+ years of professional experience in Site Reliability Engineering, Dev Ops, Infrastructure Engineering, or production‑focused Software Engineering, working on production systems and reliability‑focused initiatives

Proven experience leading multi‑sprint, multi‑engineer projects (for example, reliability, performance, or infrastructure initiatives) to successful completion with clear business impact

Thorough understanding of, and hands‑on experience with, modern SRE practices, such as:

Defining and implementing SLIs/SLOs and error budgets

Reducing toil through automation

Safe deployment and rollout patterns

Structured post‑incident reviews and continuous improvement

Software engineering experience: you’ve written and maintained production‑quality code and can work comfortably in at least one modern language (for example, Python or Node.js/Type Script)

Strong interest in, and experience with, using LLMs and AI‑assisted tooling in your workflow, including the ability to validate and improve what they generate

Strong observability skills, including:

Designing metrics, logging, and tracing for multi‑service systems

Building actionable dashboards and alerts with clear runbooks

Correlating metrics, logs, and traces to debug complex issues

Experience with tools such as Datadog, Prometheus, Grafana, Honeycomb, or New Relic (we use Datadog, but vendor‑agnostic experience is welcome)

Experience working with AWS in production and with core platform primitives such as Terraform‑based Infrastructure as Code and container/orchestration platforms (for example, Docker with ECS, EKS, or Kubernetes)

Incident management experience is a strong plus, including:
