About the Role:
As a Senior Systems Engineer, you will operate as a senior individual contributor with strong ownership across infrastructure reliability, security execution, and operational maturity. This role is hands-on and execution-focused, with an emphasis on AWS infrastructure, infrastructure-as-code, observability, and secure-by-default systems.
You will act as a trusted technical authority within a highly experienced team, bridging Infrastructure and Security, mentoring peers, and proactively communicating across functions. Success in this role requires both tactical execution and end-to-end system thinking—leaving the platform better than you found it.
Infrastructure Operations & Reliability:
Operate, scale, and modernize AWS-based infrastructure supporting highly available, uptime-driven production systems.
Design for fault tolerance, graceful degradation, and automated recovery across EC2- and ECS-based workloads.
Support the organization’s roadmap toward multi-region, globally distributed infrastructure.
Infrastructure as Code & Automation:
Build, maintain, and improve infrastructure using Terraform, Ansible, and related tooling to ensure repeatability, auditability, and resilience.
Support and evolve CI/CD pipelines (GitHub Actions, AWS tooling) with a focus on reliability, speed, and developer autonomy.
Reduce operational brittleness by creating reusable, well-documented infrastructure patterns.
Observability & Incident Response:
Implement and maintain observability using Datadog, CloudWatch, OpenTelemetry, and related tools.
Define and monitor SLOs, improve alert quality, and reduce MTTD/MTTR through actionable dashboards and runbooks.
Participate in and help mature a 24/7 on-call rotation; confidently troubleshoot and resolve incidents under pressure.
Security & Compliance:
Serve as an infrastructure security subject-matter expert, helping bridge the Infrastructure Engineering and Security teams.
Implement and operate security controls such as IAM policies, WAFs, DDoS protections, secrets management, and deployment safeguards.

Collaboration, Mentorship & Delivery:
Proactively communicate status, risks, and tradeoffs in a distributed, async-first environment.
Mentor engineers and contribute to shared learning across experience levels.
Own small-to-medium scoped projects end-to-end: breaking down work, driving execution, and following through to completion.
5+ years of experience working with cloud infrastructure or systems engineering in a production environment.
Deep hands-on experience operating and scaling production systems in AWS (ECS, EC2, ALB/ELB, ASG, IAM, VPC, Secrets Manager).
Strong infrastructure-as-code experience with Terraform and configuration management tools such as Ansible.
Experience supporting highly available, uptime-sensitive systems with on-call responsibility.
Observability expertise using tools such as Datadog, CloudWatch, and OpenTelemetry.
