Member of Technical Staff - Infra Engineer

**About Us**

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.

**The Role**

We are looking for a Infrastructure Engineer to build and scale the foundation that powers NeoSigma's AI platform. You will work across **cloud infrastructure, deployment automation, security, observability, and enterprise deployments. Some weeks you'll be deep in Kubernetes, Terraform, and platform reliability**. Other weeks you'll partner with enterprise customers to ship secure, production-ready deployments and the infrastructure that enables AI systems to run at scale.

**What you'll do**

• 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

**What we look for**

• 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)

**Our Core Values**

• **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.

**Benefits and perks**

• Competitive salary plus meaningful equity package
• Comprehensive medical benefits and generous PTO
• Flexible work arrangements
• Direct impact on company direction and technical decisions
• High ownership and the opportunity to make a career-defining impact

As a founding member, you’ll help define the technical foundation of NeoSigma. Your scope will grow with the company, from owning core systems end-to-end to shaping architecture, hiring, and engineering culture. This role has a natural path toward technical leadership or engineering management as the team scales.
