Job description

As a Senior Software Developer in Deltek's Technical Center of Excellence (TCOE), you will serve as a technical subject matter expert responsible for building scalable, high-performance solutions. The Senior Software Developer champions an AI-first approach to engineering, embedding AI tooling and AI-driven solutions into everyday development practice rather than treating AI as an afterthought. You will collaborate closely with customer-facing Technical Consultants and act as a technical anchor, developing and deploying custom solutions across multiple Deltek products.

• Develop client-specific customizations for global accounts, including Java-based ERP extensions, stored procedure hooks, custom application screens, and batch processing solutions across billing, revenue, purchasing, HR, and general ledger modules.
• Build structured, reusable code components and pattern libraries to reduce long-term maintenance costs and enable flexible deployment across all products.
• Tech Enthusiast: Stay current with emerging technologies and recommend solutions that enhance quality and efficiency.
• AI-First Engineering: Drive adoption of AI-assisted development tools (code generation, AI pair-programming, automated testing/review) to accelerate delivery and raise code quality across the team.
• AI Enablement & Coaching: Mentor developers on practical AI skills (prompt engineering, working with LLM APIs, evaluating AI-generated output) and set the standard for responsible AI use on the team.

Qualifications:

• 5-8 years of experience in development with proven expertise in technical solution delivery, architecture, process improvement, and technical leadership
• Solid understanding of Costpoint extensibility and integration concepts, with hands-on experience in one or more of: the Costpoint extensibility designer, Integration Console (WIC), stored procedures, or Java
• Familiarity with hook-based and event-driven plugin patterns within the Costpoint framework
• Direct Costpoint experience strongly preferred; equivalent depth in a comparable enterprise ERP extensibility framework (SAP ABAP, Oracle EBS, Microsoft Dynamics) considered with expectation of a Costpoint learning curve
• Hands-on experience building with LLMs/generative AI (e.g. OpenAI, Anthropic, Azure OpenAI) in production systems, not just familiarity but shipped work.
• Practical knowledge of prompt engineering, RAG, and agentic frameworks. Track record of using AI tooling to measurably improve development velocity or quality.
• Mastery of all technology stacks used by the team, including advanced proficiency in Python, Node.js, .NET, CI/CD, Serverless, and AI/LLM.
• Proficiency in both Oracle PL/SQL and SQL Server T-SQL, with experience writing SQL compatible across both platforms
• Proficiency in Maven, Git, Jira, Eclipse, Visual Studio Code, and Claude
• Experience with RESTful and SOAP API development and integration

US Citizenship required for this position
