Site Reliability Engineer MyFitnessPal · Remote · US · Site Reliability –ago

At My Fitness Pal , 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 My Fitness Pal  PEAS team. As a member of the PEAS team, you'll have the opportunity to positively impact My Fitness Pal  users through your expertise in the reliability and delivery systems that keep the My Fitness Pal  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 (Tech Ops) organization, which includes IT, Infrastructure, Security, Reliability, and Dev Ops/Dev Ex disciplines. Tech Ops seeks to enable My Fitness Pal  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 My Fitness Pal  users.

• 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 Git Hub 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

• 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)
• Proven track record leading incident response and building SLO-driven reliability practices.
• Working fluency with observability tooling…
