Site Reliability Engineer

At MyFitnessPal, we believe good health starts with what you eat. We provide tools, resources and support to enable users to reach their health goals.

We are looking for a Software Engineer III - Site Reliability to join the MyFitnessPal PEAS team. As a member of the PEAS team, you'll have the opportunity to positively impact MyFitnessPal users through your expertise in the reliability and delivery systems that keep the MyFitnessPal ecosystem fast, available, and safe to change. In addition to technical expertise, you'll find that your teammates value collaboration, mentorship, and inclusive environments.

About the team:

The Productivity Engineering: Automation & Self-Service (PEAS) team is responsible for the automation, CI/CD, and self-service platforms that product teams rely on to build, test, and ship features quickly and safely.

The PEAS team is part of the Technology Operations (TechOps) organization, which includes IT, Infrastructure, Security, Reliability, and DevOps/DevEx disciplines. TechOps seeks to enable MyFitnessPal to "ship with confidence" by delivering a secure, reliable, and low-friction runway to build and operate software at scale.

Essential Duties:

As a Software Engineer III on the PEAS team, you will own reliability across our production services and maintain security in the software delivery pipeline. You'll define how we measure and defend reliability, lead us through incidents, and make our CI/CD pipelines both faster and harder to compromise. You will play a key role in delivering an outstanding experience to MyFitnessPal users.

What you’ll be doing:

Own and evolve our SLI/SLO and error-budget frameworks, and use them to influence prioritization and product decisions

Lead incident response, drive postmortems, and turn findings into systemic fixes rather than one-off patches

Build and maintain observability across metrics, logs, and traces (Datadog), improving signal and reducing alert fatigue

Design and operate resilient, scalable infrastructure using Infrastructure as Code (Terraform)

Manage production Kubernetes and container workloads, including capacity planning and cloud-cost optimization

Own CI/CD pipelines and safe deployment strategies (canary, progressive rollout, fast rollback)

Own the security controls that live inside the delivery pipeline — integrating and tuning SAST, DAST, and SCA scanning (for example, in GitHub Actions) so issues surface while code is still in review

Implement and maintain policy-as-code (for example, OPA/Rego, Kyverno, or Conftest) to block unsafe infrastructure and Kubernetes changes at admission time

Drive vulnerability triage and remediation SLAs for pipeline- and infrastructure-level findings, prioritizing by real risk

Partner with our Security Engineer and the broader Security & Reliability disciplines — you own security in the pipeline and collaborate on the rest, rather than duplicating that function

Participate in and improve the on-call rotation; build the runbooks and automation that make on-call sustainable

Coach team members and engineers across the org on reliability patterns and operational best practices

Qualifications to be successful in this role:

5+ years in site reliability, platform, or infrastructure engineering, with clear senior-level ownership of production systems

Strong programming skills for automation and tooling (Go, Python, Typescript or similar) — you have experience building software or custom tooling, not just scripts

Deep, hands-on experience with a major cloud platform (AWS is a plus), Kubernetes, and Infrastructure as Code (Terraform is a plus)
