Senior Integration & Systems Engineer
This is a remote position.
We are seeking a Senior Integration & Systems Engineer to design, implement, and maintain reliable system integrations and technical infrastructure that support critical business operations for imaServe, our behavioral health EHR and billing platform. This role is well suited for someone who works independently, applies sound technical judgment, and produces structured, high-quality work in environments where accuracy and system reliability matter.
Our systems run in customer-managed environments, both on premises and in Azure, across multiple generations of Red Hat-based Linux. You'll work within each customer's VPN, security, maintenance-window, and change-control requirements.
Key responsibilities include:
-
Build and maintain scripts, services, and scheduled interfaces that exchange data with hospitals, HIEs, payers, and partners.
-
Monitor interfaces and resolve failed, delayed, or rejected transactions through confirmed delivery.
-
Launch new integrations from specification and testing through cutover and documentation.
-
Administer source control and manage builds, releases, backups, and tested rollback procedures.
-
Lead our transition to Git, automated builds, and CI/CD.
-
Configure, secure, patch, monitor, and troubleshoot customer-hosted Linux systems.
-
Maintain storage, capacity, backups, disaster recovery, certificates, credentials, and system performance.
-
Support varied Linux versions and lead migrations away from end-of-life operating systems.
-
Coordinate directly with customer IT and security teams during maintenance, implementations, incidents, and go-lives.
-
Participate in an on-call rotation and scheduled after-hours maintenance.
-
Create clear inventories, runbooks, and technical documentation.
-
Use Claude Code daily for scripting, code review, legacy-code analysis, and documentation—while carefully validating all output.
During your first few months, you’ll document our interfaces and customer environments, establish a repeatable release process, verify backups, improve monitoring, and assess systems requiring modernization.
Our stack includes an AlphaBASIC application transpiled to C, Red Hat–family Linux, a FairCom c-tree ISAM database, and a Windows client. Experience with these specific technologies is not required. Curiosity, patience, and sound judgment when working with unfamiliar legacy systems are essential.
This role offers significant autonomy, direct customer relationships, and the opportunity to modernize systems that support real clinical and billing operations. All work is performed under HIPAA obligations and requires careful handling of Protected Health Information.
