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
