Job description

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 to own the reliability, scalability, performance, and operational quality of the infrastructure behind that platform.

This role sits at the intersection of SRE, platform engineering, Kubernetes, distributed systems, security, and developer experience. You will design and operate systems that reduce incidents, remove operational toil, improve engineering velocity, and make reliability a shared engineering discipline across Promptly.

This is not a support role. We are looking for someone who can stay close to production, shape infrastructure decisions, lead reliability initiatives, and help engineering teams build systems that are easier to operate safely.

What you’ll be expected to do

• Design, build, and operate production-grade Kubernetes platforms across cloud, hybrid, and on-premise environments.
• Own reliability practices for critical systems, including SLOs, SLIs, error budgets, incident response, post-incident analysis, and long-term remediation.
• Improve the scalability, availability, performance, and operational resilience of Promptly's platform.
• Build and evolve Infrastructure as Code, CI/CD, GitOps, and deployment automation patterns that teams can trust.
• Design observability across services, data pipelines, infrastructure, and customer-facing products.
• Reduce operational toil through automation, internal tooling, better platform abstractions, and clearer ownership boundaries.
• Partner with product engineering teams to make reliability, security, cost, and operability part of system design from the start.
• Lead incident response with calm judgment, clear communication, and focus on systemic fixes.
• Mentor engineers on reliability, operational readiness, Kubernetes, infrastructure patterns, and incident practices.

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, quality, and accountability we apply to any production system. Strong engineers know where AI accelerates the work, where it introduces risk, and where human judgment needs to lead.

You own what you ship. You should be able to explain the design, inspect the diff, validate the behavior, check the security and privacy implications, debug failures, and operate the system in production.

If you cannot understand it, test it, secure it, and maintain it, you should not merge it.

Ownership, agency, and judgment

Senior Site Reliability Engineers at Promptly are expected to own production outcomes, not only infrastructure tasks.

You should be able to identify reliability risks before they become incidents, understand the trade-offs behind platform decisions, and create practical paths to improve resilience without slowing teams down unnecessarily.

Healthcare systems involve sensitive data, regulated environments, and real customer consequences. We need engineers who can move quickly during incidents, communicate clearly, and follow through until the system is stronger than it was before.

What we're looking for

This role is grounded in SRE and infrastructure fundamentals: production operations, Kubernetes, distributed systems, networking, observability, automation, security, and incident judgment.

Required

• 5+ years of experience in site reliability engineering, platform engineering, infrastructure engineering, DevOps, or similar production infrastructure roles.
• Deep production experience with Kubernetes, including cluster design, scaling, networking, ingress, workload management, observability, and failure recovery.
• Strong experience operating cloud, hybrid, or on-premise infrastructure. Experience with AWS, Azure, GCP, VMware, or bare‑metal environments is relevant.
• Strong Infrastructure as Code experience, especially with tools such as Terraform, Helm, or similar platform automation frameworks.
• Strong programming or scripting skills in Go, Python, Bash, or similar languages. You should be able to build internal tooling, automation, and operational workflows.
• Proven experience with reliability practices such as SLOs, SLIs, error budgets, incident response, postmortems, and remediation plans.
• Strong understanding of networking fundamentals, including DNS, service discovery, virtual networks, load balancing, ingress, TLS, routing, and firewalling.
• Hands‑on experience with observability tools such as Prometheus, Grafana, Loki, OpenTelemetry, Jaeger, Elasticsearch, or similar systems.
• Experience designing CI/CD, deployment automation, and release workflows for production systems.
• High agency in ambiguous environments. You can create clarity, make trade‑offs, and move work forward without needing every detail defined upfront.
• Strong ownership of production outcomes. You care about how systems behave after they ship.
• Strong communication skills during incidents, design discussions, and cross‑team reliability work.

Preferred

• Advanced Kubernetes expertise, including CRDs, operators, controller patterns, admission controllers, policy engines, or multi‑cluster management.
• Experience with platform engineering, internal developer platforms, golden paths, paved roads, or self‑service infrastructure.
• Experience with GitOps workflows using tools such as Argo CD, Flux, or similar systems.
• Experience in security, privacy, compliance, or regulated environments such as healthcare, fintech, or enterprise SaaS.
• Relevant certifications such as CKA, CKAD, CKS, or cloud provider certifications.
• Experience with data‑intensive platforms or distributed data systems such as Kafka, Trino, Apache Iceberg, Spark, Airflow, or similar technologies.
• Experience building SRE tooling, deployment platforms, observability frameworks, incident automation, or reliability dashboards.
• Experience with cost optimization, capacity planning, performance engineering, or infrastructure efficiency.
• Familiarity with enterprise IT constraints, private networking, customer‑managed environments, or on‑premise deployments.

You’ll be a strong fit if

• You care about production systems and the people who depend on them.
• You think reliability is an engineering discipline, not an afterthought.
• You can debug across application, infrastructure, network, and data layers.
• You know when to automate, when to simplify, and when to remove a fragile system entirely.
• You can move quickly during incidents without creating panic or noise.
• You care about observability, runbooks, tests, rollback paths, and operational readiness.
• You are comfortable with regulated environments, sensitive data, and high‑trust systems.
