About the Team

About the Role

As a Senior Software Engineer on this team youll be one of the hands-on technical engineers working closely with acquired company engineering teams to plan implement and execute their migration to CP2. Youll 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 23 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

Youre a senior engineer who has done cloud migration work before not just designed it on a whiteboard. Youve 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.

• Bachelors 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 youre about to change.

• You write clearly. Migration plans RFCs and runbooks are part of the job.

• Youre pragmatic about paved road tradeoffs you can hold the line on standards without being dogmatic when an acquisition has a legitimate reason to deviate.

• Youre comfortable with ambiguity. The first few acquisitions will not have a clean playbook; youll help write it.

Additional 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.
