Sr Software Development Engineer - Core Platform Integration

Your work days are brighter here.

We're obsessed with making hard work pay off, for our people, our customers, and the world around us. As a Fortune 500 company and a leading AI platform for managing people, money, and agents, we're shaping the future of work so teams can reach their potential and focus on what matters most.

About the Team

The Core Platform Integration Team is a new centralized team within Workday's Core Services organization that sits at the intersection of Workday's IPE (Infrastructure Platform Engineering) organization and our acquired companies. Workday has acquired several companies in the last couple of years that run multiple services across cloud service providers AWS and GCP with their own infrastructure patterns, CI/CD pipelines, and operational practices.

Our charter is to bring these companies onto CP2, Workday's cloud-agnostic "paved road" platform, so that 100% of services can run on any CSP. That means migrating workloads off CSP lock-in services (managed databases, proprietary queues, vendor-specific identity, etc.) and onto standardized CP2 building blocks for compute, networking, observability, CI/CD, and security.

This is a small, high-leverage team working directly with acquisition engineering leads, IPE platform owners, and Workday SREs. We operate in the open, driving architecture review boards, building migration scorecards, sizing onboarding effort, and producing the roadmap that shapes both what the IPE platform must build and what acquired teams must refactor. The work is technical, cross-organizational, and high-impact.

About the Role

As a Senior Software Engineer on this team, you'll be one of the hands-on technical engineers working closely with acquired company engineering teams to plan, implement, and execute their migration to CP2. You'll own the technical delta analysis for assigned acquisitions, design the migration approach, and write the code, IaC, and automation that gets services moved.

• Partner with engineering leads at 2-3 assigned acquired companies to inventory their services, dependencies, and CSP-specific footprint.
• Produce a per-service migration plan: what stays, what gets refactored onto CP2 paved-road components, and a T-shirt-sized effort estimate.
• Rewrite Terraform/Terragrunt modules to target CP2, port CI/CD pipelines, swap CSP-locked services for CP2 equivalents, and re-instrument observability to Workday standards.
• Identify gaps in the CP2 paved road and feed concrete, well-scoped feature requests back to IPE platform teams.
• Establish repeatable migration patterns (a "playbook") so future acquisition onboarding is faster.
• Actively participate in Architecture Review Boards and drive consensus across IPE and acquisition teams.

About You

You're a senior engineer who has done cloud migration work before, not just designed it on a whiteboard. You've moved real services between clouds or onto an internal platform, hit the messy parts (stateful data, IAM rewiring, DNS, secrets, certificate pinning, undocumented dependencies), and shipped the migration to completion.

Basic Qualification

• 7+ years of software/infrastructure engineering experience, with at least 3 years operating production workloads on AWS and/or GCP.
• Proficiency in using the latest AI tools (Claude Code, Cursor, Augment) as a force multiplier.
• Bachelor's degree in Computer Science, Engineering, or related discipline, or equivalent practical experience.

Other Qualification

• Strong, current Kubernetes experience (EKS, GKE, or equivalent).
• Production proficiency in Terraform (Terragrunt a plus) as your primary IaC tool.
• Strong coding skills in Go and/or Python for automation, migration tooling, and operators.
• Solid CI/CD experience (GitHub Actions, GitLab CI, Jenkins, ArgoCD, Flux, or Harness).
• Working knowledge of observability stacks (Prometheus, Grafana, OpenTelemetry, GCP Operations Suite, or equivalents).
• Practical experience with at least one managed cloud database (Aurora, Cloud SQL, Spanner, RDS).
• Strong collaborator with excellent written communication skills.

Additional Preferred Skills

• Multi-Cloud experience with GCP and AWS.
• Familiarity with secrets management, IAM least-privilege design, and basic security hygiene.
• Experience with security auditing and compliance frameworks.
