Member of Technical Staff - Infra Engineer

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 are backed by world-class investors and leaders from Google DeepMind, OpenAI, Decagon and others.

• →Design and ship enterprise-grade deployment architecture across multi-cloud (GCP), BYOC, and VPC-isolated environments for regulated customers
• →Own data retention policies end-to-end: minimal collection, defined TTLs, PII handling, and data residency baked in by default
• →Build private and secure connectivity solutions including VPC peering, PrivateLink, and Private Service Connect for customer-managed environments
• →Own our critical CI/CD infrastructure: pipelines, deployment automation, and rollout/rollback tooling across the full stack
• →Architect security from the ground up: IAM, secrets management, least-privilege access, encryption, and audit logging by default
• →Own the enterprise deployment relationship: SSO/SAML/SCIM, network configuration, and compliance documentation (SOC 2, HIPAA, GDPR)
• →Build and maintain observability: structured logging, metrics, alerting, and on-call practices across distributed deployments

• Shipped real infra at a startup and lived with the consequences
• Strong fundamentals across cloud (GCP), Kubernetes, and Terraform
• Experience with enterprise deployment patterns: BYOC, VPC isolation, SSO/SAML/SCIM, and compliance
• Security-first mindset: blast radius, attack surface, audit trails
• High ownership mentality: you see problems through and don't wait for someone else to notice what's broken
• Comfortable writing technical design docs and operational runbooks

• Bachelor's degree in CS, Engineering, or related field (or equivalent practical experience)

• Customer Obsession - We start with the customer and work backwards. We aim to earn trust through consistent delivery, thoughtful listening, and by obsessing over customers.
• 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. We prefer building and learning with customers over debating in the abstract, and we iterate based on real feedback.
• Extreme Ownership - We take responsibility for outcomes, not just tasks. Ownership means seeing problems through to completion and ensuring solutions truly work in practice.
