Member of Technical Staff - Full Stack

Human Delta is building the continuous improvement infrastructure for enterprise agents. We create a closed loop between how agents perform in production and the knowledge they rely on - identifying what went wrong, correcting the underlying cause, and continuously improving both the knowledge and the agents using it. Every failure becomes a signal that makes the entire system more reliable over time.

We are looking for a backend-leaning Full-Stack Engineer to help build the infrastructure behind Human Delta’s current platform and our next generation of agent products. Most of the difficult work is in the backend: data modeling, queues, execution pipelines, integrations, observability, reliability, and debugging distributed workflows. You should still be comfortable taking a feature through the full stack and shipping the product surface that makes the underlying system useful.

You will have meaningful ownership over architecture and product decisions while working directly with a small, highly technical team and enterprise customers. What You’ll Work On Build the backend systems powering our agent evaluation and continuous-improvement platform. Improve the data models behind evaluation datasets, experiment runs, agent traces, knowledge versions, findings, and customer-defined quality criteria.

Own enterprise integrations throughout their entire lifecycle: authentication, OAuth, webhooks, incremental syncs, backfills, rate limits, schema changes, retries, monitoring, and production support. Own features from technical design and implementation through deployment, monitoring, customer feedback, and iteration. Work directly with customers when needed to understand their systems, diagnose failures, and convert one-off requirements into reusable product capabilities.
