Project Prometheus Meta Jobs (NOW HIRING)

Our Mission Reflection's mission is to build open superintelligence and make it accessible to all. We're developing open weight models for individuals, agents, enterprises, and even nation states. Our team of AI researchers and company builders come from DeepMind, OpenAI, Google Brain, Meta, Character.AI, Anthropic and beyond. 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 defaults, cloud guardrails.
• Infrastructure & Automation: Terraform, Pulumi, Kubernetes foundations, CI/CD systems, Bazel, build caching, hermetic builds.
• Observability & Cost Governance: Prometheus, Grafana, OpenTelemetry, logging and metrics systems, FinOps, cloud cost optimization.

About You

• Strong infrastructure or platform engineering background with experience shipping production-grade systems.
• Deep expertise in at least one of: cloud platforms, network engineering, security architecture, or developer tooling - with working knowledge across the others.
• Comfortable navigating complex multi-team environments, debugging hard infrastructure problems, and building for reliability and scale.
• Thrive in a high-agency, fast-paced environment; bias toward action and impact.
• Excited about zero to one challenges - building new systems rather than maintaining legacy ones.
• Collaborative, clear communicator, comfortable working across research and infrastructure boundaries.
• Motivated by creating the secure, self-serve foundation that the world's most capable open-weight AI systems are built on.

What We Offer: We believe that to build superintelligence that is truly open, you need to start at the foundation. Joining Reflection means building from the ground up as part of a small talent-dense team. You will help define our future as a company, and help define the frontier of open foundational models. We want you to do the most impactful work of your career with the confidence that you and the people you care about most are supported.

• Top-tier compensation: Salary and equity structured to recognize and retain the best talent globally.
• Health & wellness: Comprehensive medical, dental, vision, life, and disability insurance.
• Life & family: Fully paid parental leave for all new parents, including adoptive and surrogate journeys. Financial support for family planning.
• Benefits & balance: paid time off when you need it, relocation support, and more perks that optimize your time.
• Opportunities to connect with teammates: lunch and dinner are provided daily. We have regular off-sites and team celebrations.
