Senior Software Engineer

Hextropian Systems is a Washington-based startup building a category-defining enterprise risk, governance, and compliance platform powered by custom neuro-symbolic AI systems.

Our platform evaluates incoming operational and business events against dozens to thousands of regulations in near real time to detect compliance issues, latent risk, and operational exposure. We work with highly regulated industries including Energy, Pharma Manufacturing, Banking, Biotech, and Cross-Border Retail.

We’re looking for a senior engineer who is fundamentally a systems thinker, someone who understands the entire stack through real experience, not just familiarity.

This role is for engineers who:

• Move extremely fast while maintaining engineering discipline
• Are comfortable working with AI-assisted development, but fully own correctness and quality
• Understand distributed systems, cloud deployments, operational safety, and production reliability
• Can operate effectively in highly parallelized engineering environments
• Care deeply about architecture, leverage, and outcomes

Our stack includes:

• Backend: Python, Go, Rust
• Frontend: TypeScript, React
• Infrastructure: Cloud-native distributed systems

Strong preference for candidates with:

• Software engineering or related technical degrees
• Experience in machine learning, data science, or data engineering
• Experience with LLM training or fine-tuning
• Experience with DSPy, especially RLM and GEPA workflows
• Familiarity with DSPy ecosystem implementations for Go, Rust, and other supported languages

This is initially a contract role, with potential conversion to full-time depending on fit and upcoming fundraising milestones.

Due to customer requirements, US citizenship is required.

For identity verification and interview integrity, we use Polyguard AI as part of our hiring process.
