Senior IT Systems Engineer

COMPANY DESCRIPTION Today, when you go to your doctor and get referred to a specialist, your doctor sends out a referral and tells you, “They’ll be in touch soon.” So you wait. And wait. Sometimes days, weeks, or even months. Why? Because too often providers are overwhelmed with the painstakingly tedious work required to get paid by insurance companies. Powered by proprietary models, Tennr handles the complex paperwork that gets patients through the door and providers paid, helping operators get patients the right care, at the right time, in the right setting. ROLE DESCRIPTION As a Senior IT Systems Engineer, you'll help improve and automate the internal processes that keep Tennr running. Partnering with our Head of Security and teams across the company, you'll identify opportunities, set technical direction, and own improvements from discovery through rollout and ongoing operation. Success means less manual work, more reliable systems, and a better employee experience as Tennr grows. RESPONSIBILITIES - Own the IT improvement roadmap, assessing current workflows and prioritizing automation based on employee impact, effort, reliability, and security. - Design and maintain scripts and API integrations across identity, devices, and SaaS applications, with testing, monitoring, exception handling, and recovery built in. - Automate onboarding, role changes, offboarding, and access requests with People Operations and team leads, maintaining clear approvals and least-privilege access. - Improve device lifecycle management through automated enrollment, software deployment, patching, and configuration checks. - Turn recurring support issues into lasting process improvements and self-service workflows while keeping employee and office technology reliable. - Set technical standards for IT automation, documentation, and change management, and lead adoption across People Operations, Finance, Security, and other teams. - Partner with Security on IT controls, automated compliance evidence, and incident response involving employee accounts, endpoints, and SaaS applications. - Drive projects independently from conception to completion and measure results through time saved, faster turnaround, fewer errors, and reduced recurring ticket volume. CANDIDATE QUESTIONS - 6+ years in IT systems engineering, systems administration, or a similar role, with a track record of improving existing processes and delivering useful automation. - Hands-on experience administering identity providers and SaaS applications, including SSO, MFA, SAML/OIDC, and SCIM provisioning. - Familiarity with AI systems and agents used in internal workflows, including managing non-human identities, service accounts, credentials, and permissions with least-privilege access and clear ownership. - Strong experience managing macOS devices and mobile device management platforms, including deployment, patching, encryption, and endpoint troubleshooting. - Strong scripting skills in Python, Bash, or PowerShell, with experience designing and operating API integrations and automation, including authentication, testing, monitoring, exception handling, and recovery. - Solid networking fundamentals, including DNS, DHCP, Wi-Fi, VPNs, and troubleshooting office connectivity. - A track record of independently leading improvements across multiple IT systems, with measurable reductions in manual effort, errors, or turnaround time. - Practical security judgment: you understand least privilege, endpoint protection, and how to implement controls without creating unnecessary friction. - Ability to evaluate technical tradeoffs, set direction, and lead projects from discovery through adoption with minimal guidance, communicating clearly across technical and business teams. - Experience supporting a healthcare or regulated environment, or contributing evidence to SOC 2 or HIPAA programs, is a plus.
