About The Position

Stefanini Group is hiring a Senior Enterprise Architect to design, secure, and modernize systems that support transportation, credential issuance, and toll collection across Delaware. This hands-on senior role sets technical direction while also contributing to building, reviewing, and troubleshooting systems. The architect supports three divisions with systems ranging from legacy mainframes to real-time cloud platforms, handling public safety, personal data, payment card data, and federal compliance requirements. The role supports fixed-route transit systems such as CAD/AVL, real-time passenger information, GTFS feeds, fare collection, onboard networking, and vehicle telematics; paratransit booking, eligibility, scheduling, dispatch, driver tablets, and call center integrations; and microtransit apps, routing, SaaS platforms, and APIs. It also supports DMV driver licensing, vehicle registration, credential issuance, online services, kiosks, legacy platforms, AAMVA interfaces, and REAL ID, as well as toll roadside systems, back-office operations, transponder and plate-image processing, payment processing, and interoperability. The architect defines target-state architectures and shared platforms; leads design reviews; creates architecture decision records, reference architectures, and integration patterns; and designs for availability, disaster recovery, and defined RTO/RPO targets. The position guides phased modernization of legacy systems, designs APIs and data integrations, embeds security into architecture, and supports compliance with applicable security frameworks and transportation requirements. It applies systems engineering throughout the lifecycle, shapes cloud and hybrid infrastructure strategy, and supports cloud governance, automation, cost management, and vendor assessments. The role also reviews or writes technical requirements for RFPs, evaluates vendor proposals, oversees system integrators and SaaS providers, sets technical standards, and communicates technical risks and options to executives and division leaders. Work is primarily office or hybrid, with occasional travel to division sites and facilities. After-hours and on-call support may be needed for critical incidents and maintenance windows.

Requirements

  • 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 production experience with at least one major cloud platform: AWS, Azure, or Google Cloud.
  • Working knowledge of security frameworks such as NIST CSF, NIST SP 800-53, or ISO 27001, and experience 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.
  • Ability to explain technical tradeoffs to non-technical leaders and the public.
  • Ability to balance innovation against stability on systems the public relies on daily.
  • Ability to lead through influence across divisions, vendors, and partner agencies.
  • Ability to respond to after-hours incidents on critical systems when needed.

Nice To Haves

  • 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 in PCI DSS environments and payment processing architecture.
  • Familiarity with OT and ICS security for field devices.
  • Knowledge of enterprise, solution, and integration architecture patterns, including microservices, event-driven design, and API-first design.
  • Knowledge of zero trust architecture, identity federation such as SAML, privileged access management, and data protection.
  • Knowledge of hybrid cloud networking, including VPN, private connectivity, DNS, load balancing, and SD-WAN.
  • Knowledge of high availability, disaster recovery, and business continuity design.
  • Knowledge of 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.
  • Skill in threat modeling and evaluating security controls.
  • Skill in diagnosing complex, multi-system production problems.
  • Skill in evaluating vendor solutions on technical merit, risk, and total cost of ownership.

Responsibilities

  • Define target-state architectures for division systems and shared platforms.
  • Lead design reviews and produce architecture decision records, reference architectures, and integration patterns.
  • Design high-availability and disaster-recovery solutions for revenue- and safety-critical systems, including defined RTO/RPO targets.
  • Plan phased, low-risk modernization of legacy platforms, including DMV mainframe workloads.
  • Design APIs, event streams, and data integrations across transit, DMV, tolls, and external partners.
  • Embed zero trust, identity and access management, segmentation, and encryption into system architectures.
  • 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 across 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 integration, performance, failover, and user acceptance testing strategies.
  • Shape and execute cloud strategy across AWS, Azure, or GCP, including landing zones and governance.

  • Promote infrastructure as code, CI/CD, containerization, and automated configuration management.
  • Drive cloud cost management, tagging standards, and right-sizing with finance.
  • Support FedRAMP and StateRAMP evaluations of SaaS and cloud vendors.
