ECH Field Engineer

TEKsystems•Detroit, MI

11d•$50 - $55•Remote

About The Position

The ECH Field Engineer implements 911 call-handling systems at customer sites according to the site design. The work includes on-site configuration, verification testing, cutover, and post-cutover support. This is a rotating-project role, with continual travel between sites rather than assignment to a single long-term project. The systems support live public safety operations, so the role requires methodical work, clear communication, and careful adherence to process. The current focus is on on-premises VESTA 911. VESTA NXT and other cloud work are future or limited areas; awareness of cloud connectivity is sufficient and can be learned on the job. The position is fully remote in the United States, with more than 75% travel—typically Monday through Friday every week or every other week, with occasional Sunday travel. Site work takes place in server rooms and customer locations alongside customers, channel partners, and internal support teams. A typical site configuration takes several days to a full week. The role is hourly with overtime, averaging about 47 hours per week; long days are normal and urgent cutovers may continue until midnight. The Field Engineer reports to the ECH Field Engineer Manager, with a dotted-line relationship to a TGS Engagement Manager. A seven-year CBG check is completed up front; site-specific checks and fingerprinting are handled locally.

Requirements

Be comfortable with more than 75% travel, usually weekly or every other week, including long travel days, hotel stays, and occasional Sunday travel.
Have strong written and verbal communication skills for working with customers, partners, and internal teams.
Maintain accurate documentation as changes occur and communicate with the team rather than working in isolation.
Demonstrate accountability, openness to learning, and a methodical approach to live, mission-critical systems.
Have deployment, telephony, networking, Windows Server, troubleshooting, SIP, VoIP, Layer 2, Cisco, integration, and field-engineering skills.
Have working knowledge of VoIP/SIP and telephony gateways; telephony-architect-level expertise is not required.
Be prepared for an extended VESTA 911 ramp-up; becoming solid on the system takes more than a year.

Nice To Haves

Prior hands-on VESTA 911 experience.
Experience with other 911 or call-handling platforms, public safety deployments, or telecommunications environments.
Basic-to-moderate Wireshark packet capture and analysis skills.
Familiarity with Cisco M800, 9200, or 9300 switches; M800 is the direction of travel.
Baseline experience with AudioCodes gateways.
Experience with Red Hat KVM.
Experience with serial console and device connections.
Exposure to analog FXO/FXS lines, PRI, or T1.
General Linux administration experience.
SQL Server basics and health checks.
Basic firewall and router knowledge, preferably Fortinet FortiGate.
Microsoft Hyper-V 2012 or later experience as an alternative to ESXi or KVM.
Awareness of Azure or AWS, SSO, and Active Directory.

Responsibilities

Configure assigned ECH solutions at customer sites using the site configuration checklist, including servers running on a hypervisor, Cisco switches, telephony gateways, and Windows 10/11 console positions.
Work hands-on and independently through configuration tasks while coordinating with internal configuration engineers and support chat groups.
Perform site verification testing before cutover, checking system health, connectivity among servers, console positions, and gateways, and conformance to the approved design.
Configure FXO/FXS and SIP gateways, and occasionally PRI and T1 telephony.
Support customers and channel partners during deployments by explaining the work, checking in with site contacts, and aligning on call flow and expectations.
Document all changes, update the Post Sales Document when customer call-flow needs differ from the original design, and communicate changes to the team.
Troubleshoot installation and quality issues systematically, using Wireshark where possible and escalating to support teams and subject-matter experts when needed.
Participate in and execute Methods of Procedure for the VMware-to-Red Hat KVM migration and the Windows Server 2019-to-2022 refresh.
