Founding Engineer

As a Founding Engineer at Convexia, you will build the core agentic frameworks and evaluation systems that power our Source → Diligence → Decide product. 

Your Role

• Build and iterate on agentic orchestration frameworks: Develop robust systems for tool calling, routing, memory management, guardrails, provenance tracking, and failure recovery to ensure seamless agent performance.
• Design evaluation and backtesting harnesses: Create comprehensive tools for our agents and PoS model, including offline replay, regression testing, and confidence calibration to validate and refine system accuracy.
• Own end-to-end product delivery: Manage the full lifecycle from data ingestion and processing to user experience and system reliability, incorporating tight feedback loops from customers to drive rapid improvements.
• Enhance system performance and correctness: Tackle challenges with messy, real-world inputs like PDFs, tables, slides, non-English sources, and conflicting evidence to deliver reliable results.
• Partner with founders on strategy: Collaborate on the product roadmap, customer integrations, and technical direction as we transition from a platform to owning and advancing key assets.

We’re hiring for people that are high-agency and a bit delusional. Specifically, you:

• You've built and shipped complex backend or ML systems in production, with a bias toward reliability
• You obsess over evaluation, observability, and failure modes
• You thrive in ambiguity and move fast without waiting for permission
• You communicate clearly and take ownership in low-process environments

Other things we like:

• You've been underestimated before
• You've been told you're "too intense"
• You get bored in the absence hard problems 
• Hacker house vibes appeal to you
