Senior Platform Engineer

About the role

A Senior Platform Engineer on the Enterprise Technology Development Team develops, tests, implements, and maintains proprietary business system platforms for Empyrean and our clients. This role involves troubleshooting systems problems, improving existing applications, and setting up and maintaining cloud infrastructures. The position requires writing and maintaining infrastructure as code (IaC) using Terraform, primarily with AWS, to ensure repeatable and predictable infrastructure deployment.

Responsibilities

• Work within an agile development team in sprints with deliverables and demonstration of results.
• Participate in architectural design meetings.
• Work closely with principal/staff engineers when implementing or changing platform features.
• Perform code reviews and uphold coding standards.
• Implement and maintain infrastructure as code using Terraform (primarily AWS), applying reusable IaC module patterns, policy guardrails, and environment promotion standards.
• Build and optimize CI/CD pipelines for application and infrastructure delivery, including plan/apply workflows, promotion gates, rollback strategies, and release evidence collection.
• Drive pipeline quality by implementing automated checks for security, compliance, policy-as-code, testing, and deployment reliability across team-owned and adjacent delivery environments.
• Maintain and enhance cloud tooling and shared platform services while implementing improvements to reliability, developer experience, and operational efficiency.
• Share platform improvements and changes with development teams.
• Ensure proper documentation of standard procedures.
• Maintain existing tools and infrastructure as necessary.
• Provide production environment support, including troubleshooting and ensuring system stability.
• Mentor other engineers and help raise the skill level of the team.
• Stay current with industry trends and make recommendations to help the organization innovate and excel.

Requirements

• Advanced AWS engineering experience across core services (e.g., VPC, IAM, EC2, ECS/EKS, S3, RDS, CloudWatch, Route53, KMS, and networking/security controls).
• Advanced Terraform experience designing reusable IaC modules, managing remote state, implementing environment strategies, and supporting safe promotion workflows.
• Strong understanding of infrastructure-as-code patterns, including module versioning, drift detection, immutable infrastructure, and policy/compliance guardrails.
• Advanced CI/CD expertise for both application and infrastructure delivery, including automated validation, promotion gates, rollback/rollback-forward strategies, and release traceability.
• Strong automation and scripting skills (e.g., Bash, PowerShell, Python) to support platform operations, deployment workflows, and reliability tasks.
• Effective cross-functional collaboration with Product, Engineering, QA, Security, and Operations to align priorities, manage risks, and deliver reliable outcomes.

Preferred Qualifications

• C# skills with familiarity in .NET Core/.NET ecosystem.
• Strong observability and operational troubleshooting skills, including metrics/logging/alerting patterns, incident triage, root-cause analysis, and long-term remediation planning.
• Strong understanding of platform reliability, performance, security, and maintainability tradeoffs in cloud-native systems.
• Advanced time-management and multi-tasking skills.
• Advanced written and verbal communication skills, specifically in documentation.
• Detail-oriented, quality-conscious, yet flexible to others' ideas and suggestions.

Qualifications

• Bachelor’s degree preferred (or equivalent years of experience in computer science or completion of a related boot camp program).
• 5-10 years of experience as a software engineer.
• Proven hands-on experience with AWS platform engineering and infrastructure automation at scale.
• Proven experience building and operating CI/CD pipelines for both infrastructure and application delivery, including promotion controls, rollback strategies, and release quality checks.
• Experience supporting production systems with observability, incident response, root-cause analysis, and long-term remediation ownership.
• Experience implementing security and compliance controls in cloud and deployment workflows (e.g., IAM, secrets management, policy validation, and auditability).
• Experience with enterprise application environments and cross-functional delivery contexts is preferred.
• Experience with benefits administration and Health & Welfare domains is a plus; equivalent combinations of education, experience, and training will be considered.
