Member of Technical Staff Engineering Lead, Platform Foundations

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.

Reflections Platform Foundations team builds and operates the foundational layer every engineering team depends on cloud and multi-cloud infrastructure networking primitives security guardrails and developer tooling. The team defines the opinionated golden paths that make the safe scalable cost-predictable path also the easiest one to follow so engineers can ship quickly without reinventing the foundation each time.

As Platform Foundations Lead youll provide front-line leadership of the team that builds this layer. Youll build mentor and grow a team of infrastructure engineers guide the technical and architectural decisions across cloud networking security and developer infrastructure and work closely with every engineering team that builds on top of you. Youll stay close enough to the stack to make targeted contributions as an individual contributor and to maintain a deep understanding of the teams technical work. Managing cloud and infrastructure vendors and the important deals that come with them is a core part of the job.

• Build mentor and grow a high-performing team of infrastructure and platform engineers. Coach and support your reports in understanding and pursuing their professional growth.

• Provide front-line leadership of engineering efforts to build the foundational platform multi-cloud design networking identity and security and developer infrastructure and the golden paths and secure defaults that make the safe path the easy path.

• Stay hands-on: become familiar with the teams technical stack enough to make targeted contributions as an individual contributor.

• Manage day-to-day execution: prioritize the teams work and manage projects in a highly dynamic fast-paced environment.

• Guide technical and architectural decisions emphasizing scalability robustness security and cost predictability networking primitives (routing DNS load balancing BGP) large-scale Kubernetes IAM and policy-as-code CI/CD and build systems and observability.

• Work closely with our research and engineering teams and manage the cloud and infrastructure vendor relationships and deals the platform depends on.

• Raise the bar for technical judgment prioritization communication and execution in a fast-moving environment.

• Experience building mentoring and growing infrastructure or platform teams while staying technically hands-on. (Comfortable growing into leading a team of 10 quickly if you havent managed at that scale before.)

• Deep infrastructure or platform engineering experience with real ownership of production-grade systems at scale.

• Strong coding ability and the credibility to earn the technical trust of a strong team.

• Deep expertise in at least one of: cloud platforms network engineering security architecture or developer tooling with working knowledge across the others and the ability to learn the rest.

• Fluency with the modern infra toolkit: Terraform/Pulumi Kubernetes CI/CD and build systems (e.g. Bazel) and observability (Prometheus/Grafana/OpenTelemetry).

• Experience managing cloud and infrastructure vendors including negotiating and operating important deals.

• Ability to guide strategy and drive execution across a multi-cloud multi-team environment and to partner effectively with research and engineering teams.
