Job Description

About the company

---------------------


Joist AI is a technology company revolutionizing the way professionals in the architecture, engineering, and construction (AEC) industry manage marketing and revenue operations. Our AI-powered software streamlines workflows, making it easier for teams to collaborate, innovate, and succeed.

About the role

We are looking for a

Platform Engineer

to design and build the internal foundation that powers our development lifecycle. Your goal is to eliminate friction for our engineering teams by building a self-service "Internal Developer Platform." You won't just manage cloud environments; you will treat the infrastructure as a product, creating automated workflows and abstractions that allow our developers to deploy, scale, and manage their own services with high confidence and zero "ticket-waiting."

What you'll do

Build the "Golden Path":

Design and maintain internal developer tools and self-service portals that abstract away the complexity of AWS, allowing developers to provision resources independently.

Infrastructure as Code (IaC) Leadership:

Lead the transition toward modular, reusable IaC (Terraform/Pulumi) modules that other teams can consume as a service.

CI/CD Evolution:

Architect robust, high-speed delivery pipelines that integrate automated security scanning, testing, and blue/green deployment patterns.

Standardization & Governance:

Define and enforce organization-wide standards for logging, secrets management, and networking to ensure a consistent environment across all microservices.

System Observability:

Build the "observability-as-a-service" layer, ensuring every new service is automatically instrumented with the right dashboards and alerting thresholds.

Cross-Functional Enablement:

Act as a consultant to product engineering teams, helping them optimize their service architecture for the platform.

What You'll Bring

4-6 years

of experience in Platform Engineering, DevOps, or Site Reliability, with a clear focus on building internal tooling.

Cloud Architecture Mastery:

Deep expertise in

AWS

services (Lambda, RDS, S3, Step Functions, VPC networking) and how to stitch them together securely.

Advanced IaC:

Proficient in writing modular, dry, and testable Terraform or CloudFormation at scale.

Developer Mindset:

You write clean code (Python, Go, or Bash) and approach infrastructure with the same rigor as product software (version control, PRs, testing).

Strategic Thinker:

You can identify repetitive developer "pain points" and design automated solutions to solve them permanently.

Experience we'd be particularly excited about

Platform-as-a-Product:

Experience treating internal tools as a product (gathering requirements from devs, documentation, and driving adoption).

FinOps & Scaling:

Proven track record of optimizing large-scale cloud spend without sacrificing performance.

Security Integration:

Experience implementing "Shift Left" security (e.g., Snyk, Trivy) within the developer workflow.

Interest in ML/LLM Ops:

Experience or interest in building platforms specifically for Machine Learning workloads (GPU orchestration, model serving).

Attributes:

Exceptional

attention to detail

, strong

analytical and problem-solving skills

, and excellent written and verbal communication.

Education:

Bachelor's degree in Computer Science, Engineering, or a related field (or equivalent practical experience).
