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. You will partner with engineering leads at 2-3 assigned acquired companies to inventory their services, dependencies, and CSP‑specific footprint (managed DBs, IAM, networking, queues, secrets, observability stack, etc.). You will produce a per‑service migration plan: what stays, what gets refactored onto CP2 paved road components, and a T‑shirt‑sized effort estimate (S/M/L). If and as needed, you will rewrite Terraform/Terragrunt modules to target CP2, port CI/CD pipelines, swap CSP‑locked services for CP2 equivalents, and re‑instrument observability (logs, metrics, traces, SLOs) to Workday standards. We will rely on you to identify gaps in the CP2 paved road and feed concrete, well‑scoped feature requests back to IPE platform teams — with enough technical specificity that they can be prioritized and built. You will help establish repeatable migration patterns (a "playbook") so future acquisition onboarding is faster than the first. You will be an active participant in Architecture Review Boards, separating hard blockers (re‑architecture required) from soft blockers (tool swaps), and help drive consensus across IPE and acquisition teams. This role involves collaborating with teams across multiple locations and time zones. You will need to be adept at communicating effectively and building strong relationships with colleagues in diverse locations.

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 to accelerate code understanding, migration work, and documentation. Bachelor’s degree in Computer Science, Engineering, or related discipline, or equivalent practical experience.

Other Qualification

Strong, current Kubernetes experience (EKS, GKE, or equivalent). You can debug a misbehaving pod, write a sane Helm chart and reason about networking and resource limits. Production proficiency in Terraform (Terragrunt a plus) as your primary IaC tool, and experience refactoring IaC across accounts/projects/regions. Strong coding skills in Go and/or Python for automation, migration tooling, and operators, not just glue scripts. Solid CI/CD experience (GitHub Actions, GitLab CI, Jenkins, ArgoCD, Flux, or Harness) and comfort redesigning pipelines, not just maintaining them. Working knowledge of observability stacks (Prometheus, Grafana, OpenTelemetry, GCP Operations Suite, or equivalents) and what good SLI/SLO instrumentation looks like. Practical experience with at least one managed cloud database (Aurora, Cloud SQL, Spanner, RDS) including migration or replication. Strong collaborator. You know how to earn trust with a team whose code you're about to change. You write clearly. Migration plans, RFCs, and runbooks are part of the job. You're pragmatic about "paved road" tradeoffs — you can hold the line on standards without being dogmatic when an acquisition has a legitimate reason to deviate. You're comfortable with ambiguity. The first few acquisitions will not have a clean playbook; you'll help write it.

Preferred Skills

Multi‑Cloud experience with GCP and AWS. Familiarity with secrets management, IAM least‑privilege design, and basic security hygiene (vulnerability scanning, image signing, mTLS). Experience with security auditing and compliance frameworks.

Our Approach to Flexible Work

With Flex Work, we’re combining the best of both worlds: in‑person time and remote. Our approach enables our teams to deepen connections, maintain a strong community, and do their best work. We know that flexibility can take shape in many ways, so rather than a number of required days in‑office each week, we simply spend at least half (50%) of our time each quarter in the office or in the field with our customers, prospects, and partners (depending on role). This means you'll have the freedom to create a flexible schedule that caters to your business, team, and personal needs, while being intentional to make the most of time spent together. Those in our remote "home office" roles also have the opportunity to come together in our offices for important moments that matter.
