Middleware Engineer; REMOTE

Koniag IT Systems, LLC, a Koniag Government Services company, is seeking a Middleware Engineer with a Secret security clearance to support KITS and our government customer. The position is remote.

Benefits include medical, dental, and vision insurance, 401(k) retirement plan, paid time off, paid parental leave, life and disability insurance, flexible spending accounts, commuter benefits and tuition reimbursement.

Koniag IT Systems, a Koniag Government Services company, is seeking an experienced Middleware Engineer to support a critical Government Identity, Credential, and Access Management (ICAM) initiative. This role supports a large-scale Application and Systems Enablement effort issued under an ICAM Enterprise Master IDIQ Contract. The Middleware Engineer will serve as a specialized technical contributor responsible for designing, developing, and deploying custom middleware solutions, integration tools, connectors, and scripts that enable legacy and non-standard applications to integrate with the centralized ICAM technical stack—leveraging Okta for Identity Provider (IdP) services and SailPoint Identity IQ (IIQ) for Identity Governance and Administration (IGA)—in direct support of the Department of Defense (DoD) Zero Trust Execution Roadmap.

The ideal candidate is a skilled software and integration engineer with deep experience in middleware development, API design, and enterprise application integration. This individual must be comfortable operating in a complex federal IT environment where applications span a wide spectrum of technical maturity—from modern cloud-native systems to deeply entrenched legacy codebases—and where custom engineering solutions are often required to bridge the gap between legacy identity mechanisms and modern ICAM capabilities.

This position requires an active Secret clearance and may require occasional travel to Government facilities. Primary work will be performed remotely.

The Middleware Engineer will serve as the primary technical expert for custom integration development within the ICAM enablement program, responsible for engineering bespoke middleware solutions that facilitate the onboarding of applications that cannot natively support modern identity protocols. This individual will work closely with migration engineers, the Okta/SailPoint platform engineer, the migration team lead, and application owners to analyze integration requirements, design appropriate technical solutions, and deliver production-ready middleware capabilities that are secure, scalable, and maintainable.

The Middleware Engineer is expected to apply sound software engineering principles and federal security standards to all developed solutions while maintaining rigorous documentation and contributing to the broader enablement program.

• Design, develop, test, and deploy custom middleware solutions, integration proxies, protocol translators, and adapter components that enable legacy applications to authenticate and authorize through the ICAM technical stack when native protocol support is unavailable.
• Engineer custom connectors, REST and SOAP APIs, scripts, and integration libraries that facilitate the connection of non-standard applications to Okta IdP and SailPoint IIQ, leveraging existing platform connectors where possible and developing bespoke solutions where they are not.
• Analyze legacy application architectures, authentication mechanisms, and data flows to identify integration gaps and design technically sound middleware approaches that bridge proprietary or outdated identity systems with modern SAML, OAuth 2.0, OIDC, and SCIM-based ICAM capabilities.
• Develop and maintain reusable integration libraries, sample code…
