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.
Systems engineering
- 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.
Minimum qualifications
- Bachelor's degree in computer science, information systems, engineering or a related field. Equivalent experience may substitute year for year.
- 10+ years of progressive IT experience, including at least 5 years in an architecture, senior systems engineering or technical lead role.
- Demonstrated experience designing and delivering large, integrated, mission-critical systems.
- Hands-on experience with at least one major cloud platform (AWS, Azure or Google Cloud) in production.
- Working knowledge of security frameworks such as NIST CSF, NIST SP 800-53 or ISO 27001, and of implementing their controls.
- Experience with networking, identity and access management, Linux and Windows server environments, and relational databases.
- Experience writing technical requirements and overseeing vendors or system integrators.
- Ability to pass a criminal background check and fingerprinting, including CJIS-level screening.
Preferred qualifications
- Experience in a state DOT, transit agency, tolling authority, DMV or other public-sector transportation setting.
- Domain knowledge in one or more of: CAD/AVL and GTFS, paratransit scheduling, AAMVA systems, toll back-office and interoperability, or ITS.
- Experience modernizing mainframe or legacy platforms.
- Experience with API management platforms.
- Experience with PCI DSS environments and payment processing architecture.
- Familiarity with OT and ICS security for field devices.
Knowledge, skills and abilities
Knowledge of:
- Enterprise, solution and integration architecture patterns, including microservices, event-driven design and API-first design.
- Zero trust architecture, identity federation (SAML, etc), privileged access management and data protection.
- Hybrid cloud networking, including VPN, private connectivity, DNS, load balancing and SD-WAN.
- High availability, disaster recovery and business continuity design.
- Federal and state rules that shape transportation IT, including FTA, FHWA, ADA, DPPA, PCI DSS and CJIS.
Skill in:
- Producing clear architecture diagrams, standards and decision records.
- Threat modeling and evaluating security controls.
- Diagnosing complex, multi-system production problems.
- Evaluating vendor solutions on technical merit, risk and total cost of ownership.
Ability to:
- Explain technical tradeoffs to non-technical leaders and the public.
- Balance innovation against stability on systems the public relies on daily.
- Lead through influence across divisions, vendors and partner agencies.
- Respond to after-hours incidents on critical systems when needed.
Working conditions: Primarily office or hybrid work. Occasional travel to division sites, transit facilities, DMV offices, toll facilities and data centers. Possible after-hours and on-call support for critical incidents and maintenance windows.
