Decision Systems Architect

Job description

## **Decision Systems Architect** **Team:** Product **Location:** Flexible / Remote **Reporting to:** Product Leadership ### **Role Overview** Sena is designed to translate complex business intent into decision-grade outputs at scale. The Decision Systems Architect plays a critical role in **advancing Sena’s decision capabilities** by formalizing judgment, reasoning frameworks, and evaluation logic into system-native structures. This role focuses on extending the breadth, depth, and consistency of Sena’s decision logic as new customer use cases, signal types, and business questions emerge. This is a product-embedded role at the intersection of systems thinking, applied reasoning, and AI enablement. ### **Key Responsibilities** The Decision Systems Architect is responsible for: - Designing and refining decision frameworks that guide how Sena interprets customer intent - Defining signal mapping logic that structures how business questions are decomposed into actionable signals - Establishing configuration schemas that specify how data must be captured to support decision-grade outputs - Creating evaluation criteria and quality standards used to assess system outputs - Identifying recurring patterns, edge cases, and failure modes, and formalizing them into reusable system logic - Producing structured artifacts that directly inform Product and AI development workflows - Collaborating closely with Product, AI, and Engineering teams to ensure decision logic is encoded effectively into Sena All work in this role is expected to be **system-oriented, reusable, and extensible**. ### **Role Impact and Growth** This role contributes to Sena’s evolution as new business problems, customer objectives, and data environments emerge. As the system’s capabilities expand, the focus of this role naturally shifts toward: - New classes of customer questions - New signal types and constraints - More complex decision structures and tradeoffs - Higher-order reasoning patterns that have not yet been formalized This role remains at the frontier of decision design as the product evolves. ### **Qualifications and Profile** We are looking for individuals who demonstrate: - Strong systems thinking and the ability to formalize complex reasoning - Experience designing frameworks, methodologies, or structured decision logic - The ability to translate ambiguous problems into clear, explicit structures - Comfort working in highly autonomous, fast-moving environments - Intellectual curiosity and a willingness to challenge established methods Candidates may come from applied research or technically rigorous domains where deep reasoning, formal abstraction, and the hands-on design of complex decision systems were core to the work. ### **Cultural Fit** We value people who: - Take initiative and operate with high ownership - Produce high output with limited resources - Prefer autonomy and accountability - Are inventive and comfortable rejecting outdated approaches - Are deeply focused and driven by hard problems This role is best suited for individuals who enjoy building foundational systems and pushing the boundaries of what software can reason about. ### **How Candidates Are Evaluated** Candidates are evaluated based on: - Their ability to structure and reason through ambiguous problems - The clarity, generalizability, and technical rigor of the frameworks they design - How effectively their thinking can be translated into system-level logic - The quality and rigor of their judgment under real-world constraints - Their ability to independently design, execute, and iterate on decision frameworks We prioritize demonstrated capability and depth of thinking over resumes alone. ### **Summary** The Decision Systems Architect helps define **how Sena thinks** as it continues to expand across new domains and use cases. This role is central to shaping the system’s long-term decision intelligence and is designed for individuals who want to work at the intersection of reasoning, systems, and product design.
