Automation Test Engineer

SAIC · Sterling

SAIC hiring an Automation Engineer to build automated test coverage and perform hands-on manual testing for systems where hardware and software are integrated. You will design and maintain automated tests (API, service, and some UI), develop and test supporting C#, Python code, and validate integrated components end to end — devices, backend services, middleware, and the data between them. You will work in an Agile team alongside developers and DevOps across the full software development lifecycle, maintaining automation in CI/CD and tracking plans and defects in Jira.

This position is hybrid remote and requires 2 days on-site in Sterling, VA per week.

Key Responsibilities

Design, build, and maintain automated test scripts that verify functionality, security, and usability across API, service, and UI layers.
Develop and test C#, Python code as project requirements dictate.
Implement automated integration, regression, functional, and system tests during feature development.
Perform manual and exploratory testing of integrated hardware and software systems — including LPR, biometric/facial recognition, and RFID devices — validating read accuracy, correlation to the correct vehicle or transaction, and behavior under real and adverse conditions.
Reproduce field and edge conditions (device faults, dropped, duplicate, or out-of-order messages, timing skew, degraded inputs) and confirm graceful end-to-end handling.
Develop and maintain test plans and test cases; write SQL or Unix scripts for test-data generation and test-harness automation.
Maintain and improve automation frameworks and CI/CD pipelines, and troubleshoot issues in the automation systems themselves.
Investigate defects across the stack using logs, traffic captures (TCP/HTTP), and the command line; isolate whether a fault is hardware, software, configuration, or network.
Report and manage defects in Jira; produce test summaries and raise functional, performance, and requirement-discrepancy tickets.
Collaborate with development and DevOps teams and participate in Agile ceremonies such as daily stand-ups and sprints.
