Senior Site Reliability Engineer, Infrastructure Security
Promptly · Remoto, BR
### **About the company** **What’s Promptly in a nutshell** Promptly is building the first patient\-centered global evidence network, offering real world data sharing and monetization capabilities. Together with a selected network of Partners, we generate new knowledge from harmonized datasets, augmented with the collection of longitudinal patient\-reported data and patient\-generated digital biomarkers within a secure and privacy\-preserving environment. We answer the question – is this patient treatment the best it could possibly be? **What’s our purpose** We exist to empower every patient and every health organization on the planet with evidence on the outcomes of care! Why do we get up in the morning? Well, most healthcare professionals have chosen to work in healthcare driven by their desire to make a difference in patients’ lives. And so have we! We have chosen to follow this calling by addressing the biggest problem in healthcare: the lack of real\-world evidence on the outcomes of care. For us, society denying patients better care due to lack of access to data is unethical, in a world where technology improved so many aspects of our world. Making the right evidence available to healthcare organizations to help prevent one lost life, one care complication, one failed treatment is the moral obligation that big tech companies have – it’s our Hippocratic Oath. At Promptly, everything we do is driven by our core purpose: to promote better healthcare at lower costs for patients every day, by making health outcomes available. ### **About the role** Promptly is building healthcare data infrastructure for real\-world evidence, patient\-reported outcomes, and AI\-enabled healthcare products. We work with sensitive, fragmented, and regulated data across hospitals, partners, patients, and life sciences organizations. We are looking for a Senior Site Reliability Engineer, Infrastructure Security to strengthen the reliability and security of the infrastructure behind that platform. This is an SRE role with a strong security focus. You will work on the systems that run Promptly: Kubernetes, cloud and hybrid infrastructure, networking, CI/CD, observability, secrets, identity, access controls, deployment workflows, and incident response. Your job is to make our platform harder to break, easier to operate, and safer for teams to build on. We are not looking for someone who only writes policies or reviews tickets from the outside. We need an engineer who can stay close to production, understand how systems fail, improve security through better infrastructure, and help engineering teams adopt secure defaults without slowing useful work to a crawl. The right title for this role could also be Platform Security Engineer or Infrastructure Security Engineer. We are using SRE in the title because the work sits inside the team that owns production infrastructure, reliability, and operational quality. **What you’ll do** * Design, build, and operate secure, reliable Kubernetes platforms across cloud, hybrid, and on\-premise environments. * Improve the security posture of Promptly’s infrastructure, including identity, access control, network boundaries, secrets management, workload isolation, auditability, and secure deployment patterns. * Own reliability practices for critical systems, including SLOs, SLIs, incident response, post\-incident analysis, and long\-term remediation. * Build secure platform defaults through Infrastructure as Code, GitOps, CI/CD, policy\-as\-code, hardened base images, reusable modules, and clear ownership boundaries. * Partner with engineering teams to make security part of system design, deployment, observability, and operations from the start. * Improve vulnerability management for infrastructure, containers, dependencies, cloud services, and Kubernetes workloads. Help the team prioritize what matters and fix it properly. * Strengthen production access patterns, including least privilege, break\-glass access, audit trails, service accounts, workload identity, and human access to sensitive systems. * Improve observability and alerting for reliability and security signals across services, infrastructure, data pipelines, and customer\-facing products. * Help prepare Promptly for security reviews, customer assessments, regulated environments, and future certification work by building systems that produce useful evidence naturally. * Lead or support incidents with calm judgment, clear communication, and focus on systemic fixes. * Mentor engineers on secure infrastructure, operational readiness, Kubernetes, incident practices, and pragmatic risk reduction. **How we build with AI** At Promptly, AI\-assisted development is part of how we work. We expect engineers to use coding agents, copilots, code search, AI\-assisted debugging, and automated review to move faster through real engineering work. We expect engineers to use AI as part of a modern development workflow, with the same standards of craft, quali
