Decision Systems Architect

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.
