About the role

Intellectual Honesty - We operate with high trust and low ego.
Ideas matter more than titles, and we communicate openly and directly while assuming good intent, even in strong disagreement.
Bias for Action - We set high standards and move quickly to meet them.

IAM, secrets management, least-privilege access, encryption, and audit logging baked in by default Design and enforce data retention policies - minimal collection, defined TTLs, PII handling - so privacy is structural, not an afterthought

blast radius, attack surface, audit trails Experience with SQL, object storage, and caching layers for high-throughput workloads

We prefer building and learning with customers over debating in the abstract, and we iterate based on real feedback.

NeoSigma is a product-driven research lab building the intelligence layer that helps close the feedback loop between your customers, products, and AI systems.
We are a small, intensely technical team of researchers and engineers who have trained frontier-scale models and widely used AI products and agents at MIT, Parallel Web, Essential AI, Apple, and Amazon.
We aim to earn trust through consistent delivery, thoughtful listening, and by obsessing over customers.
structured logging, metrics, alerting, and on-call practices Lead enterprise deployment architecture - design and ship BYOC and VPC-isolated deployments for regulated enterprise customers
