Platform Reliability Engineer

About the role

Appnovation is building an internal agent platform on AWS Bedrock AgentCore for a global life sciences client, working as a dedicated delivery pod with the client's engineers. As Platform Reliability Engineer you make the platform visible and dependable: you build OpenTelemetry instrumentation, observability integrations, tracing, SLOs, alerting and cost monitoring for token and compute spend. This is a named-team engagement, so the person proposed is the one who starts.

Key responsibilities

• Build OpenTelemetry instrumentation standards for agents, tools and platform services, and make adoption easy for teams.
• Connect AgentCore Observability and CloudWatch with the client's existing tools (e.g. Datadog, Splunk, Grafana).
• Set up end-to-end tracing across agent steps, model calls, tool calls and multi-agent handoffs.
• Define SLOs for latency, availability and error rates, and build useful, low-noise alerting.
• Track token usage and compute spend by team, agent and environment, with dashboards, budgets and alerts for unexpected spikes.
• Write runbooks, support incident response and run post-incident reviews that lead to real fixes.

Required profile

• 6+ years in SRE, platform reliability or observability engineering, with strong hands-on AWS experience.
• Experience defining and running SLOs, error budgets and alerting strategies.
• Experience building cost visibility and FinOps reporting on AWS (Cost Explorer, CUR, tagging strategies).
• Clear communication, able to turn data into decisions for technical and non-technical audiences.
• Prior consulting experience; life sciences industry experience preferred.

Required skills

• OpenTelemetry (SDKs, collectors, exporters) and distributed tracing.
• Amazon CloudWatch and at least one enterprise observability platform (Datadog, Splunk, Grafana, New Relic or similar).
• Scripting and coding in Python, Go or TypeScript.
• Preferred: LLM/agent monitoring, LLM observability tools (Langfuse, Arize, LangSmith), and IaC (Terraform or AWS CDK).
