Sr Automation Engineer
Location
San Antonio, Austin, or Dallas (Texas only)
Hybrid role
No relocation
Work Authorization
US Citizen or Green Card only
Must be eligible for future full-time conversion (no guarantee)
This is a high-visibility, greenfield role building a new integration testing automation practice from scratch.
The engineer will act as:
A hands-on automation builder (not coordinator)
A technical owner of integration test framework
A bridge between multiple enterprise systems (ESB pipeline layer)
This is effectively a solo “founding automation engineer” role initially.
100% automation-focused (no manual testing)
Must build and own backend integration test frameworks
Validate end-to-end system integrations across enterprise services
Act as technical checkpoint for ESB-driven data flows
Work across multiple teams (upstream/downstream systems)
Tech skills
Karate framework (must-have)
BDD (Behavior Driven Development)
5–6+ years pure automation experience
Strong backend/service/API automation focus
MuleSoft (external integrations)
ESB (Enterprise Service Bus systems)
Validation of cross-system workflows (ESB ↔ downstream apps)
IBM MQ (enterprise messaging)
Apache Kafka (event streaming validation)
Key use case:
Validate messages flow correctly across: ESB → MQ → Kafka → downstream systems
Java (automation + frameworks)
Python (headless automation, data setup, queue injection)
Computer Science degree strongly preferred (especially for conversion to FTE)
Key responsibilities
🔹 Build Automation from Scratch
Design and implement a new integration testing framework
Establish standards and automation architecture
🔹 End-to-End Integration Validation
Test full enterprise data pipelines:
Digital apps
ESB layer
Mainframe / backend systems
Ensure data correctness across systems
🔹 Messaging & Queue Validation
Validate:
ESB message routing
MQ message delivery
Kafka event publishing
Ensure reliability of asynchronous workflows
🔹 Cross-Team Technical Coordination (NOT MANAGEMENT)
Work directly with multiple engineering teams
Coordinate integration readiness
Support ESB release validation
🔹 Hands-On Engineering Ownership
Must actively write automation code
Must build tools/scripts/frameworks
NOT a QA coordinator or manual tester
Red flags
Manual testers
UI testing focused profiles
QA coordinators or “watchers”
Non-hands-on automation engineers
Weak Fit Signals
Selenium/UI-heavy background only
No backend/API automation experience
No messaging or integration systems exposure
Ideal candidate profile
Strong backend automation engineer
Experience with:
API testing
message queues (Kafka / MQ)
integration pipelines
Comfortable with distributed enterprise systems
Strong Java + Python scripting ability
Experience building frameworks from scratch
Industry
Banking domain experience is NOT required
Technical depth matters more than industry background
Interview
Deep technical screen with senior engineers
Focus on:
automation framework design
integration testing architecture
messaging/queue validation
⏰ Likely scheduled around 4:00 PM CST
Stakeholder + leadership interview
Focus:
system thinking
ownership
communication across teams
Flexible work from home options available.
