Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Applications Architect - **Company:** BigBear.ai, Inc. - **Location:** United States - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** Application Programming Interfaces (APIs), Applications Architecture, Application Layers, Audit Trail, Data Architecture, Human-Computer Interaction, Data Streaming, Systems Integration, Management of Software Versions, Enterprise Application Integration, Enterprise Software Applications, Integration Frameworks, Api Gateway, Enterprise Service Bus, Servicenow - **Published:** August 11, 2026 - **Apply:** https://www.clearancejobs.com/jobs/9087772/applications-architect ## About the Role * Clearance: Must maintain an active Top Secret security clearance * Bachelor's Degree and 10 to 12 years of experience; Master's Degree and 8 to 10 years of experience; PhD and 5 to 7 years of experience (in lieu of Bachelor's degree, 6 additional years of relevant experience) * 7+ years of experience in application architecture, including designing complex, integrated enterprise applications * Demonstrated ServiceNow platform architecture experience (beyond development/configuration)-including patterns for extensibility, integrations, and governance * Strong API and integration design experience (REST patterns, event-driven patterns, data contracts, integration reliability) * Experience bridging data architecture and application implementation (working closely with data architects and developers to convert models into usable application interfaces) * Strong communication skills with the ability to align developers, architects, and stakeholders on design decisions and tradeoffs * Practical UX judgment for operational tools (adjudicator-facing / case management environments), focusing on usability, auditability, and throughput What we'd like you to have Tools & Technical Environment (Preferred/Used) * ServiceNow architecture tooling and platform capabilities (platform architecture guidance, integration patterns, and platform governance). * API gateway design and implementation patterns. * ServiceNow IntegrationHub (or equivalent integration tooling) and enterprise service bus (ESB) patterns where appropriate. Key Behavioral Competencies * End-to-end ownership: drives coherent application architecture across multiple components and teams. * Systems thinking connects user workflows, data contracts, and integration mechanics into a durable design. * Pragmatic decision-making: balances speed, maintainability, platform constraints, and user experience. * Collaboration: effectively bridges the Chief Data Architect and ServiceNow development teams to avoid design gaps and rework. ## Description The Application Architect owns the design of the application layer above the data architecture-specifically how ServiceNow, the case management user interface, and adjudicator-facing tools integrate with the underlying signal ingestion and scoring layers. This role bridges the Chief Data Architect's schema and data flow designs with the ServiceNow Developers' build and configuration work, ensuring the overall solution is cohesive, scalable, secure, and usable for operational/adjudicator workflows. What you will do * Own and evolve the end-to-end application architecture for the case management and adjudication experience, built on/around the ServiceNow platform. * Design how ServiceNow integrates with signal, scoring, and analytics layers (events, entity resolution outputs, risk scores, and decision-support artifacts). * Translate data architecture (schemas, canonical models, and data contracts) into application patterns that developers can implement cleanly. * Define API and integration patterns: service boundaries, interface contracts, error handling, idempotency, versioning, and performance considerations. * Architect integration approaches using API gateway patterns and/or enterprise integration patterns (e.g., ESB-style orchestration where required). * Guide the implementation team on ServiceNow platform architecture best practices (scalability, maintainability, upgrade-safe customization, and platform guardrails). * Ensure application designs support operational reality: adjudicator task flows, case queues, auditability, explainability/traceability of scores, and human-in-the-loop decisions. * Partner with UX and stakeholders to apply strong judgment to workflow UX for adjudicator-facing tools (clarity, efficiency, and reduction of cognitive load). * Participate in architecture reviews and support delivery with design artifacts, reference implementations, and technical governance. ## Related Videos - [20 billion requests a week: Upgrading Twilio's API gateway at scale](https://www.wearedevelopers.com/videos/100234-20-billion-requests-a-week-upgrading-twilio-s-api-gateway-at-scale) - [Resilient by Design: Building Robust Architectures in High-Stakes Financial Systems](https://www.wearedevelopers.com/videos/2106-resilient-by-design-building-robust-architectures-in-high-stakes-financial-systems) - [Applying Agile Principles to Incident Management ](https://www.wearedevelopers.com/videos/101-applying-agile-principles-to-incident-management) - [Why make use of an integration platform in today's software developments and infrastructure?](https://www.wearedevelopers.com/videos/758-why-make-use-of-an-integration-platform-in-today-s-software-developments-and-infrastructure) - [Our GitOps approach for deploying an Identity Provider and an API Gateway in a SaaS company](https://www.wearedevelopers.com/videos/776-our-gitops-approach-for-deploying-an-identity-provider-and-an-api-gateway-in-a-saas-company) - [No Keys for the Robot: GitOps as the Control Plane for Autonomous Agents](https://www.wearedevelopers.com/videos/100095-no-keys-for-the-robot-gitops-as-the-control-plane-for-autonomous-agents) ## Related Articles - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers) - [What Makes WeAreDevelopers World Congress Different From Every Other Tech Event?](https://www.wearedevelopers.com/magazine/701-what-makes-wearedevelopers-world-congress-different-from-every-other-tech-event) - [Events like RSAC Get You CISOs.
