Senior Technical Architect – Cloud, Infrastructure & Security

• 04-Nov-2026 to 18-Nov-2026 (UTC)
• Dover, DE, USA
• Full Time
• 40 Weekly Hours

Position Description

• - The Delaware Department of Transportation is hiring 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.

Key responsibilities:

System design and architecture

• - Define target-state architectures for division systems and the shared platforms that connect them.
• - Lead design reviews and produce architecture decision records, reference architectures and integration patterns.
• - Design for high availability, disaster recovery and defined RTO/RPO targets on revenue- and safety-critical systems.
• - Help to plan modernization of legacy platforms (for example DMV mainframe workloads) through phased, low-risk migration.
• - Design APIs, event streams and data integrations across transit, DMV, tolls and external partners.

Security

• - Embed security into architecture from the start, including zero trust, identity and access management, segmentation and encryption.
• - Lead security architecture reviews for new systems and major changes.
• - Align systems with NIST CSF and NIST SP 800-53, and support PCI DSS, CJIS, DPPA and state security policy compliance.
• - Assess OT and roadside system security for toll lanes, onboard transit equipment and field networks.
• - Apply systems engineering practice across the lifecycle: requirements, traceability, interfaces, verification and validation.
• - Follow FHWA Systems Engineering guidance and regional ITS architecture requirements on federally funded projects.
• - Define and manage interface control documents between agency systems and vendor platforms.
• - Guide testing strategy, including integration, performance, failover and user acceptance testing.

Cloud and infrastructure

• - Shape and execute the agency's cloud strategy across AWS, Azure or GCP environments, including landing zones and governance.
• - Design hybrid architectures that connect on-premises data centers, field devices and cloud services.
• - Champion infrastructure as code, CI/CD, containerization and automated configuration management.
• - Drive cost management, tagging standards and right-sizing in partnership with finance.
• - Support FedRAMP and StateRAMP evaluation of SaaS and cloud vendors.

Vendor, procurement and leadership

• - Review and sometimes write technical requirements for RFPs and evaluate vendor proposals and architectures.
• - Provide technical oversight of system integrators and SaaS providers through delivery and operations.
• - Set technical standards and best practices across teams.
• - Translate technical risk and options into clear recommendations for executives and division leaders.
