Member of Technical Staff - Platform Foundations

OUR MISSION

Reflection is a research lab making intelligence open and accessible for everyone to use, customize, and build on. We build open models that let anyone control their intelligence and help shape the future of AI. Our mission: make intelligence open and accessible to all.

FOUNDATIONS

VISION:

Build and operate a company-wide foundations platform that accelerates every team by providing reliable, scalable developer infrastructure, SRE capabilities, and high-throughput data ingestion tooling enabling Reflection to move faster as we scale.

WHAT THIS TEAM DOES

Build and operate the foundational platform layer that every engineering team depends on. Define opinionated golden paths for cloud infrastructure, networking, and access patterns so the safe and scalable path is also the easiest to follow. Work across cloud infrastructure, network primitives, security guardrails, and developer tooling to ensure engineers can ship quickly without sacrificing reliability, security, or cost predictability.

- Define and maintain golden paths for cloud projects, networking, and access patterns.

- Ship secure defaults and guardrails that make the safe path the easy path.

- Build and operate core networking primitives including routing, DNS, load balancing, and connectivity.

- Establish baseline observability and operational hygiene across services and infrastructure.

- Own developer infrastructure such as build systems, CI/CD, caching, and test infrastructure to keep engineers shipping fast.

- Drive cloud cost visibility and reduction through tooling, guardrails, and optimization without slowing teams down.

WHAT YOU'LL WORK WITH

- Cloud & Multi-Cloud Architecture: GCP, AWS, multi-cloud design, VPC architecture, private DNS, load balancers, advanced routing (BGP), large-scale Kubernetes clusters, control plane scaling.

- Identity & Security Foundations: IAM, OIDC, RBAC, KMS, secrets management, policy-as-code (OPA, Gatekeeper), secure defau...
