The Role:

We are seeking a hands‑on Infrastructure Tech Lead who thrives in building from 0‑1 and driving execution, directly contributing production‑level systems while shaping our core technical foundation. You will collaborate closely with the founding team to architect, deploy, and scale the cloud infrastructure powering F2's AI‑driven enterprise analytics platform.

What you'll do:

• Hands‑on platform building. Architect and implement foundational cloud infrastructure from scratch: compute, networking, CI/CD, and observability. Actively writing infrastructure‑as‑code and shipping production systems, not just diagrams.

• Own the infrastructure architecture. Define and execute the technical vision and multi‑year roadmap for our AWS‑based platform (ECS/Fargate, containerized Python and Node services), ensuring rapid iteration while scaling reliably with enterprise demand.

• Run durable, AI‑heavy workloads. Operate and scale our workflow orchestration layer (Temporal), streaming pipelines, vector search infrastructure, and high‑throughput LLM inference paths; balancing latency, throughput, and cost.

• Design for security and compliance. Build infrastructure that meets SOC 2 requirements from day one: multi‑tenant isolation, secrets management, least‑privilege IAM, audit logging, and encrypted data flows across storage, database, and AI providers.

• Establish operational excellence. Set and uphold standards for IaC, deployment pipelines, incident response, SLOs, and on‑call practices; mentor engineers to foster a culture of reliable, observable, cost‑efficient systems.

• Cross‑functional collaboration. Partner with product, backend, frontend, and enterprise customers to translate requirements (data residency, uptime guarantees, deployment models_ into pragmatic infrastructure solutions.

What you bring:

• Hands‑on technical leadership. 7+ years building and scaling mission‑critical cloud infrastructure on AWS and/or GCP, with demonstrated experience architecting platforms from the ground up.

• Deep container and orchestration expertise. Production experience with ECS/Fargate, Kubernetes, or equivalent: including service networking, autoscaling, zero‑downtime deploys, and multi‑environment release strategies.

• Infrastructure‑as‑code fluency. Strong command of Terraform, Pulumi, or Cloud Formation, plus CI/CD pipeline design (Git Hub Actions or similar) and Git Ops workflows.

• Data and AI infrastructure experience. Familiarity operating Postgres at scale (RDS, Supabase, or self‑managed), Redis, message/workflow systems (Temporal, SQS, Kafka), and ideally vector databases or LLM serving infrastructure.

• Security‑first mindset. Practical experience with SOC 2 (or similar) compliance programs, IAM design, VPC architecture, secrets management, and multi‑tenant data isolation.

• Execution‑driven mindset. You thrive in environments where you own systems end‑to‑end, iterate rapidly, and deliver production‑ready solutions; and you measure success in uptime, latency, and dollars saved.

• Passionate builder who enjoys solving complex distributed‑systems challenges and iterating toward clear, impactful goals.
