Senior Application Operations Engineer (Hybrid)

Senior Application Operations Engineer

VIATEQ Corporation is looking for a Senior Application Operations Engineer to support our prime contractor and government customer in Washington, DC. The position is hybrid and requires 1 day on-site. This position requires the candidate to be able to obtain a Public Trust.

This Senior Application Operations Engineer provides expert-level technical engineering and operations support for the client's enterprise application portfolio, integration platforms, middleware, and SaaS environments. This individual serves as a senior technical resource within the enterprise applications and integration team, independently handling complex application engineering tasks, driving platform-level improvements, and serving as a qualified backup to the Applications & Integration Lead when needed.

This role is distinguished from the Applications & Integration Lead by its focus on deep technical engineering and platform-level execution rather than team leadership and program oversight. The Senior Application Operations Engineer brings authoritative subject-matter expertise to complex application incidents, integration challenges, and platform engineering problems, resolving them independently and contributing to the continuous improvement of the client's enterprise application environment.

This individual must demonstrate expert-level technical depth across enterprise application operations, integration engineering, and SaaS platform administration, with the ability to operate autonomously on complex, cross-domain problems and deliver measurable improvements to application reliability, performance, and security in a Federal enterprise environment.
