Job description

Stefanini Group is hiring! Stefanini is looking for Senior Enterprise Architect in Dover, DE (Hybrid)

Work Hours: M-F (37.5 hours)

Work Location: Dover, DE (Hybrid)

Interview: In-Person only

We are looking for a Senior Technical Architect to design, secure and modernize the systems that move people, issue credentials and collect tolls across the state.

This is a hands-on senior role: you will set technical direction, and you will also build, review and troubleshoot.

You will work across divisions whose systems range from decades-old mainframes to real-time cloud platforms. The work touches public safety, personal data, payment card data and federal compliance, so sound architecture and security judgment matter as much as technical depth.

Divisions You Will Support

You will be the senior technical voice for three divisions with very different systems, users and regulators.

Divisions Supported (including But Not Limited To)

• Transit: fixed route: CAD/AVL, real-time passenger information, GTFS and GTFS-Realtime feeds, fare collection, onboard networking and vehicle telematics. Real-time data from hundreds of vehicles; public-facing uptime; FTA reporting (NTD).
• Transit: paratransit: Trip booking, eligibility, scheduling and dispatch, driver tablets, call center integration ADA service obligations; protected health and eligibility data.
• Transit: microtransit : On-demand booking apps, dynamic routing, third-party platform integrations and APIs, Vendor-hosted SaaS; data sharing and integration with fixed route and paratransit.
• DMV: Driver licensing and vehicle registration, credential issuance, online services, kiosks, legacy mainframe or COBOL platforms, protected personal data; AAMVA interfaces; REAL ID; high transaction volume.
• Tolls: Roadside lane systems, back office and customer service centers, transponder and plate-image processing, payment processing, interoperability hubs, 24x7 revenue-critical operations; interstate interoperability.
