Love building reliable systems, and want to make a difference?

Arcadia’s customers rely on us to securely process and deliver high-value healthcare insights. Reliability, availability, performance, and security are foundational to trust—especially when systems support critical workflows and handle PHI. As a Principal Site Reliability Engineer, you’ll set reliability strategy across teams, drive cross-cutting platform improvements, and ensure we can scale delivery without scaling operational burden.

What Success Looks Like

In 3 months

Build deep context on Arcadia’s platform, production risks, and operational practices. Participate in on-call/incident response and quickly improve signal quality for at least one critical domain (dashboards, alerts, traces, runbooks). Identify a high-leverage reliability initiative and align stakeholders on scope, success metrics, and milestones.

Establish SLOs/error budgets for key customer journeys, drive operational readiness standards for launches, and lead remediation for recurring incidents with measurable reductions in customer impact and MTTR. Deliver major toil-reduction improvements via automation and self-service workflows.

Own and execute a reliability program with cross-org impact (e.g., GitOps delivery guardrails, observability platform evolution, resilience/DR improvements, or secure infrastructure controls). Influence architecture decisions, establish org-wide operational standards, and mentor Staff engineers—raising the reliability and security bar across Arcadia.

Act as the technical leader for reliability for one or more domains; set direction and standards while remaining hands-on where it matters most

Drive reliability strategy across critical services: define SLOs/SLIs, error budgets, and reliability KPIs aligned to customer journeys and outcomes

Own incident response maturity: lead complex incidents, improve incident command practices, and ensure high-quality RCAs with prioritized, tracked remediation

Architect and implement automation to reduce toil and risk: runbook automation, self-service tools, and safe operational workflows (Python + Argo Workflows)

Advance GitOps delivery practices using Argo CD: promotion strategies, progressive delivery/canaries, and guardrails that reduce deploy risk

Scale infrastructure management with Crossplane and Terraform: reusable patterns, policy controls, and paved roads for teams

Lead operational readiness and reliability reviews for new features/architectural changes; reinforce non-functional requirements (availability, latency, security, cost)

Improve performance and cost efficiency through capacity planning, load testing, right-sizing, and architecture recommendations across AWS services

Champion infrastructure security best practices for environments that handle PHI (least privilege, secrets management, auditability, and defense-in-depth)

Mentor Staff and Senior engineers through design reviews, code reviews, pairing, and documentation; raise reliability standards across teams

8+ years of experience in SRE, platform engineering, systems engineering, or related roles operating production services at scale

Demonstrated principal-level impact: leading cross-team initiatives, influencing architecture decisions, and driving sustained improvements in reliability and operations

Expertise in Kubernetes operations and troubleshooting, including safe rollout/rollback patterns, workload debugging, and operational guardrails

Strong GitOps experience with Argo CD; experience building delivery workflows and automation using Argo Workflows

Strong infrastructure orchestration and provisioning experience with Crossplane and Terraform; ability to define reusable platform patterns and controls

Deep AWS experience (IAM, networking/VPC, compute, storage, managed services, observability) and strong understanding of reliability and failure modes in cloud systems

Proficiency in Python for building automation, tooling, and reliability improvements

Strong incident management and on-call leadership experience, including measurable improvements (availability, MTTR, alert quality, cost, or operational maturity)

Excellent communication skills: can translate technical risk and reliability tradeoffs to engineering leadership, product, and stakeholders; produces high-quality docs/runbooks

Experience with ScyllaDB or similar distributed databases (e.g., Cassandra) and their reliability/performance characteristics

Experience with Spark or data processing platforms, including reliability and cost considerations for large-scale workloads

Familiarity with agentic coding practices and principles (safe automation, reviewable changes, guardrail-first workflows)

Strong infrastructure security knowledge: threat modeling for cloud/Kubernetes, RBAC/IAM design, secrets management, supply chain security, and security observability

Customer Focus: champions customer impact; drives SLO definition with product partners; participates in incidents to limit customer impact; may engage customers to understand problems

Technical Leadership: leading cross-team technical representative; negotiates interfaces; anticipates edge cases; designs telemetry for availability and reliability

Total Ownership: owns outcomes from requirements and design through production support; transitions complex changes with multi-phase rollouts and long-term ownership

Effective Communication: communicates to diverse audiences; finalizes key documentation (runbooks, guides, FAQs); synthesizes standards and best practices

Proactive Leadership: coaches senior/peer teams primarily through review; delegates appropriately; sets clear expectations (Definition of Done) and improves service processes/rotations

Be a part of a mission driven company that is transforming the healthcare industry by changing the way patients receive care

A flexible, remote friendly company with personality and heart

Employee driven programs and initiatives for personal and professional development
