Senior DevOps Engineer L3

Senior DevOps Engineer (L3)

As a Senior DevOps Engineer at Spring, you are a strategic leader and technical expert responsible for designing, building, and scaling our infrastructure platforms and delivery systems. You help set the standard for reliability, observability, cost-efficiency, and velocity across engineering — and play a critical role in enabling Spring to scale securely and sustainably.

You own cross-functional infrastructure initiatives that support new products, integrations, or compliance requirements. You contribute to the long-term evolution of Spring’s platform architecture and collaborate closely with engineering, product, and business leadership to ensure infrastructure decisions support strategic objectives. You mentor other engineers, lead technical design efforts, and serve as a go-to partner for high-risk or business-critical systems.

At this level, you’re expected to deeply understand how Spring’s technical architecture supports our business. You know how key services interact across domains — from payment reconciliation to identity verification to customer communications. You anticipate and mitigate systemic risks, lead readiness reviews, and help shape platform roadmaps that balance scale, reliability, and speed. You also collaborate with security, IT, sysadmins, and network teams on strategic concerns like multi-region availability, compliance automation, VPN routing, SOC2 readiness, data loss prevention, and endpoint security.

What you’ll do:

• Lead the design and implementation of scalable, secure, and cost-efficient cloud infrastructure.
• Own architecture and execution of high-impact platform initiatives (e.g., CD migration, zero-downtime deploys, logging architecture).
• Collaborate with Security, IT, and Infrastructure teams to define and implement org-wide access, audit, and reliability standards.
• Proactively identify technical debt, scalability concerns, and risk across multiple systems and services.
• Guide platform investments and architecture strategy in partnership with engineering and product leadership.
• Mentor engineers and set best practices in observability, incident response, and infrastructure evolution.

Requirements:

• Deep expertise in a major cloud provider, such as AWS, and Infrastructure as Code (IaC) tools like Terraform, CloudFormation, or CDK.
• Extensive, hands-on experience with containerization and orchestration technologies, such as Docker, Kubernetes (and its variants like EKS), and Helm.
• Strong proficiency in a programming language like Python or Go for creating robust automation and tooling.
• Deep expertise in designing and managing CI/CD pipelines, with experience in modern practices like GitOps using tools such as ArgoCD or Flux.
• Expert-level knowledge of Linux/UNIX systems administration, version control (Git), and internals.
• Advanced understanding of networking (VPC design, DNS, routing, service mesh) and cloud security (IAM, threat modeling, compliance automation).
• Deep understanding of observability, monitoring, and alerting using tools such as the Prometheus stack (Prometheus, Grafana, Loki) and/or commercial platforms like Datadog.
• Proven experience leading infrastructure strategy and operating high-availability production systems.
• Strong leadership, cross-functional influence, and a business-first mindset when making technical trade-offs.
