Platform Engineer

Kepler • New York, NY

7d • $200,000 - $280,000 • Onsite

About The Position

Kepler is building the infrastructure layer that wraps around AI models to make their outputs reliable, traceable, and verifiable. The company started in finance, creating a research product that allows analysts to supercharge their workflow. The architecture, which includes provenance, deterministic computation, and verification, is applicable to other high-stakes industries like chemicals, legal, and healthcare. The founding team has extensive experience from Palantir and Meta in building large-scale data infrastructure. Kepler is backed by prominent investors in the AI and data space.

Requirements

• 5+ years building and operating production cloud platforms.
• Owned the AWS account, the IaC repo, and the pager.
• Deep AWS fluency (VPCs, IAM, KMS, EKS or ECS, RDS) and IaC discipline.
• Pulumi preferred, Terraform or CDK experience translates.
• Track record building developer platforms: CI/CD, paved-path tooling, internal services.
• Shipped enterprise auth (SSO/SAML/SCIM) and the audit/SOC 2 work that comes with it.
• Comfortable in Rust or Python for systems work; able to read and contribute.
• Think of platform as a product, not a service.
• Prioritize making paths to production shorter over shipping new services.
• Experience fixing underlying systems rather than just symptoms.
• Set compounding architectural standards, cost discipline, and observability defaults.
• Care about the end-user's experience with the shipped product.
• Proactive in fixing issues rather than filing tickets.
• Provide design feedback before PRs are merged.
• Communicate proactively and respond promptly to teammate requests.
• Adapt to changing plans while still shipping work.

• Stand up the enterprise deployment model (single-tenant, in-VPC, BYOK).
• Set the security baseline (SOC 2 controls, audit logging, identity, network isolation).
• Establish the paved path: service templates, CI/CD, secrets management, and observability defaults.
• Drive Kepler's database strategy at scale, focusing on Postgres performance, replication, tenant isolation, and schema evolution.
• Own production reliability, including SLOs, on-call rotations, incident response, and postmortems.
