About the role :

You will build out Kong on the IRS platform and move APIs onto it in planned waves, without breaking the systems that call them. You will work in a migration factory with clear IRS approval gates, two week sprints, and a lead platform engineer who has run this environment for years.

What you will do :

Configure Kong Gateway Enterprise control and data planes, Workspaces, RBAC, services, routes and plugins on Red Hat OpenShift and cloud.

Convert webMethods API definitions to Kong configuration using decK templates, kept in Git.

Migrate simple APIs (routing, OAuth2 or OIDC, mTLS) by template, and medium APIs with consumer, ACL and certificate setup grouped by provider.

Help redesign the few complex APIs that use custom webMethods policies, using standard Kong plugins first.

Run functional equivalency tests: send identical requests to the webMethods and Kong versions, then compare status, headers, payload, auth and latency.

Support dual run cutovers with gradual traffic shifts, and rehearse rollback every wave.

Apply security patterns for mTLS, OAuth2 client credentials, JWT, ACL, IP restriction and rate limiting, each approved by IRS.

Follow IRS change control: impact assessment, lower environment testing, written rollback, Change Advisory Board (CAB) approval.

Write runbooks and migration records so others can support what you built.

What you bring :

4+ years in API gateway, integration or middleware engineering.

Hands on configuration of Kong, or a comparable gateway such as webMethods API Gateway, Apigee, MuleSoft or AWS API Gateway.

Working knowledge of REST, HTTP, TLS and mTLS, OAuth2, OIDC and JWT.

Experience with Kubernetes or OpenShift and declarative configuration in Git.

Comfort with Linux, shell scripting and at least one of Python or Go.

Bachelor's degree in a technical field, or equivalent experience.

Ability to obtain and keep an IRS Moderate Background Investigation (MBI); you must meet IRS suitability and residency requirements.

Nice to have:

Kong certification, CKA, or a cloud certification.

IBM webMethods experience, especially API migration.

An active IRS MBI or prior IRS work.

Custom Kong plugin work in Lua or Go.
