Why Sabel Systems
Sabel Systems designs and delivers digital engineering ecosystems for DoD programs, enabling teams to connect data, systems, and personnel within secure, scalable environments. Our solutions empower programs to make faster decisions, close sustainment gaps, and meet the digital acquisition requirements.
Rather than simply proposing transformation, we implement and operate it at scale. Our method is clear: we orchestrate existing tools into a governing system of record, ensuring government ownership of infrastructure and traceable decisions. There’s no vendor lock, no proprietary baselines, and no need for ATO rebuilds during transitions.
Sabel Systems is redefining modern defense acquisition. If you seek to solve complex challenges at scale and want your work to directly accelerate military capability while reshaping the DoD’s approach to digital engineering, this is the place for you.
Complexity Simplified. Mission Amplified.
What You’ll Do
• Lead the overall design, architecture, and target-state definition of enterprise-grade Appian solutions — including process models, rules, CDTs (Custom Data Types), portals, and interfaces — ensuring scalability, maintainability, and alignment with DoD business objectives across multiple applications
• Define target-state architecture for new environments and platform migrations, including environment setup, configuration strategy, and integration patterns across the Appian application portfolio
• Gather, analyze, and translate complex requirements from DoD stakeholders into enterprise technical specifications and solution architectures, partnering closely with business analysts and product owners
• Architect and guide the design of API integrations (REST, SOAP, JDBC) connecting Appian applications with legacy systems, cloud platforms, and third-party services; establish integration standards and reusable patterns for the development team to follow
• Define and oversee ETL (Extract, Transform, Load) and data migration strategy from legacy systems to new Appian-based environments, ensuring data integrity and compliance throughout
• Establish SQL and data architecture standards and oversee relational database design across Appian applications; guide developers on performance optimization and schema design best practices
• Own the security architecture for Appian solutions, including authentication/authorization design, cybersecurity requirements, and Authority to Operate (ATO) activities — partnering with ISSOs/ISSMs on security control implementation and system security documentation to achieve and maintain system accreditation
• Establish and enforce coding standards, architectural governance, and implementation best practices across projects and teams; lead code reviews and technical design reviews
• Participate in and help shape Agile/Scrum processes at the program level; guide sprint planning, technical backlog prioritization, and cross-team coordination using Jira
• Serve as the final escalation point for complex technical issues; lead root cause analysis on system-wide or cross-application problems and define preventive architectural changes
• Lead technical demonstrations and architecture reviews with clients and senior stakeholders; translate technical tradeoffs into business terms for both technical and non-technical audiences
• Mentor and develop Sr. Developers and Lead Developers; establish Appian best practices, technical governance, and growth pathways across the development organization
• Define strategy for leveraging Appian AI/ML capabilities across the application portfolio, including document processing, chatbots, and predictive workflows
What You Bring

• Bachelor's degree in Computer Science, Information Systems, Engineering, Mathematics, or related field
• Appian Lead Developer Certification (L4+) or equivalent advanced Appian certification
• Proven experience defining target-state architecture, environment strategy, and technical governance across multiple Appian applications or a large enterprise portfolio
• Strong SQL expertise with experience establishing database architecture standards and optimizing schemas at scale; proficiency with Oracle, SQL Server, or similar relational databases
• Demonstrated experience architecting API integrations using REST, SOAP, and web service technologies, including establishing integration patterns and standards for development teams
• Experience designing and overseeing ETL and data migration strategy across complex, multi-system environments
• Proficiency with Agile/Scrum methodologies at a program or portfolio level; experience using Jira or similar project management tools
• Excellent communication, stakeholder management, and executive presentation skills
• Deep understanding of federal security standards, compliance requirements, and Section 508 accessibility guidelines
• Working knowledge of cybersecurity requirements and the Authority to Operate (ATO) process (e.g., RMF, security control implementation, and system security documentation)
• Proven track record establishing technical governance, coding standards, and mentorship programs across development teams
Preferred
• Appian Certified Expert-level credentials or multiple advanced Appian certifications beyond Lead Developer (L4)
• Experience with Appian AI capabilities including document processing (RPA), intelligent forms, and generative AI integrations at a platform/strategy level
• 5+ years of combined experience in software development and/or technical consulting in government or federal contracting environments, ideally in an architecture capacity
• Experience with cloud platforms (AWS, Microsoft Azure, Oracle Cloud) in enterprise or government contexts, including architecture-level decision-making
• Knowledge of SAFe (Scaled Agile Framework) or other enterprise agile methodologies
• Experience with DevOps practices, CI/CD pipelines, Git version control, and automated testing frameworks at an architecture/standards level
• Familiarity with DoD/Federal standards including FISMA, FedRAMP, and federal IT acquisition regulations (FAR/DFAR)
