Senior Site Reliability Engineer

 

Lamina is searching for a Site Reliability Engineer (Level 3 / Senior), to join our Lamina team. On our Lamina product team, you will partner with Product, Engineering, Product Security, and our Technical Architect to design, build, operate, and secure the platform that powers our product. You will join the team responsible for reliability, availability, and operational excellence for the platform — implementing infrastructure as code, improving observability and incident response, and hardening services in AWS.

Level 3 — Senior SRE: West Monroe Expectations & Ownership

As an SRE engineer at West Monroe, you are a senior individual contributor who routinely exercises independent judgment, leads complex technical initiatives, and is accountable for end-to-end outcomes. For this Site Reliability Engineer role, Level 3 expectations include:

· Owns the reliability, operability and security of multiple platform services or a critical product domain in production across regions/environments.

· Designs and implements platform architecture and automation (Terraform modules, CI/CD, container platforms) that are reusable and production-ready.

· Demonstrates deep technical expertise in cloud infrastructure (AWS), IaC, and observability, and is the go-to person for complex technical problems.

· Regularly partners with Product, Security and Engineering to influence product and roadmap decisions from an operability and security perspective.

· Drives tradeoffs between reliability, cost, performance and security, and can clearly articulate impact to product and business stakeholders.

 

Site Reliability Engineers (Level 3) on our Lamina product have these primary responsibilities:

Functional Responsibilities:

· Design, build, and operate resilient, secure infrastructure and platform automation in Amazon Web Services (AWS).

· Implement and maintain Infrastructure as Code (IaC) using Terraform (modules, state management, testing, CI/CD).

· Instrument and improve observability: metrics, logging, tracing, dashboards and alerting.

· Automate operational tasks and repetitive processes (scripting, tooling, runbooks) to reduce toil and improve consistency.

· Partner closely with Product Security to implement secure-by-design practices, vulnerability remediation, secrets management (AWS Secrets Manager, Vault), IAM best practices, and compliance requirements.

· Collaborate with engineering teams to design for operability — performing reliability reviews, production readiness checks, and resilience testing where appropriate.

Internal Responsibilities:

· Strong problem-solver who drives pragmatic, data-informed decisions to improve reliability and performance.

· Efficiently manage multiple priorities in a fast-paced, team-oriented Agile environment.

· Advocate for automation, standardization and continuous improvement across engineering operations.

Qualifications:

· Bachelor’s degree in Computer Science, Engineering or a related field preferred, or equivalent experience.

· 5+ years of experience in site reliability, systems engineering, platform engineering, or related infrastructure role (Level 3 / Senior).

· Demonstrated experience designing, deploying and operating production systems at scale in AWS.

· Deep hands-on experience with Terraform (modules, remote state, workspaces).

· Strong Linux system administration, networking fundamentals, and storage concepts.

· Experience with containerization and orchestration (Docker) and building CI/CD pipelines.

· Strong knowledge of monitoring/observability, logging, distributed tracing and alerting best practices.

· Experience owning incident response, postmortems, SLOs and operational playbooks.

· Practical knowledge of product/security collaboration — threat modelling, secure configuration, vulnerability remediation and secrets management.

· Excellent collaboration, communication, and mentoring skills; comfortable working cross-functionally with product and security teams.

You have experience with several of our core technologies:

· Cloud: Amazon Web Services (EC2, S3, RDS, VPC, IAM, Lambda, EKS)

· Infrastructure as Code: Terraform (modules, providers, remote state)

· Containerization & Orchestration: Docker

· Observability: CloudWatch, Datadog, Prometheus, Grafana, OpenTelemetry

· Logging & Tracing: ELK (Elasticsearch/Logstash/Kibana), Splunk, Jaeger/Zipkin

· CI/CD & Automation: Jenkins, GitHub Actions, Azure DevOps, Terraform Cloud/Enterprise

· Languages & Scripting: Python, Go, Bash

· Security & Secrets: AWS Secrets Manager, HashiCorp Vault, IAM best practices

· Incident & Ops Tooling: PagerDuty, ServiceNow/Jira, Runbook tooling

Other:

· Thrive within a fast-paced, collaborative, Agile/Scrum project environment.

· Excellent team, organizational, and verbal/written communication skills.

· Experience mentoring junior team members and providing design/release reviews.

· You’re pragmatic, curious, and passionate about building reliable, secure, observable platforms.

· Excellent communication ability with team members and clients in English.

· A commitment to inclusion and diversity, and openness to new ideas and perspectives.
