About The Position

REEF’s mission is to connect the world to your block.
We transform underutilized urban spaces into neighborhood hubs that connect people to locally curated goods, services, and experiences. Together we are leveraging the power of proximity to keep our communities moving forward in a sustainable and thoughtful way.
We operate in a fast-paced, constantly evolving, startup-style environment across North America, the UK, and Europe.

We are looking for a skilled engineer to take ownership of REEF OS martketplace infrastructure. Our infrastructure is built on AWS and managed through Terraform (IaC).
The system is designed to support multiple isolated environments (Production, Staging, Testing) across separate AWS accounts, interconnected via a central management account. It leverages a modular architecture to ensure consistency, scalability, and security.

Requirements

• Deep understanding of Terraform, including custom modules, state locking, workspaces, and best practices for production environments.
• Strong hands-on experience with core AWS services: Networking: VPC, Subnets, NAT Gateways, Route53 (Internal/External DNS), VPNs. Compute: EC2, Auto Scaling Groups, ALBs. Storage/Database: RDS, Aurora, S3. Security & Access Control: Security Groups, NACLs, IAM roles/policies, Secrets Manager.
• Proficiency in Bash and Python for glue code and automation tasks. Experience with Makefiles is a plus.
• Experience with HashiCorp Vault, SSH certificate management, and AWS IAM.
• Comfortable managing Bastion hosts and debugging Linux-based systems.
• Git-based reviews, documentation-first mindset, ability to partner with app teams on database migrations, secrets, and release hygiene.

Responsibilities

• Maintain, refactor, and extend our Terraform codebase. You will work with modules, workspaces, and state management to provision resources like VPCs, EC2 instances, RDS databases, and ALBs.
• Manage a multi-account AWS strategy, including a central "Master" account for shared services (Vault, Monitoring) and satellite accounts for specific applications.
• Oversee the integration of HashiCorp Vault for secrets management (KV secrets, database credentials) and manage IAM roles/policies to ensure least-privilege access.
• Improve developer workflows using Makefiles, Shell scripts, and Python automation (e.g., certificate renewal).
• Maintain and enhance our monitoring stack, primarily based on NewRelic, Zabbix, and Sentry ensuring high availability and proactive alerting.
• Collaborate with development teams to ensure smooth deployment pipelines through GitHub actions, where code pushes automatically trigger infrastructure updates or application deployments.
• Prioritize documentation and standardized processes to keep the infrastructure predictable and reliable.

Benefits

• We offer a dynamic, fast-paced work environment, opportunities for professional growth, and a benefits package including medical and other location-specific benefits based on your home location.
