1d • Remote

About The Position

As an Internal Tools Engineer with a strong focus on backend development, you will work on applications that support internal and external company needs, including product builds, licensing workflows, revenue analysis, and operational management across Engineering, Sales, Product, and Finance. The tools range from Bash CLI tools to a medium-sized Ruby on Rails application that provides internal and customer-facing interfaces, connects to third-party systems, and serves AI agents through an MCP server. The primary technology stack is Rails, Postgres, and Terraform/AWS.

You will report directly to the COO and join a small internal tools team, partnering closely with Engineering, Security, and go-to-market teams. You will work independently, collaborate with teammates, and focus on whichever work is most valuable at the moment.

The position is fully remote and async-first, with minimal meetings and a strong writing culture. Nutrient describes its culture as collaborative and growth-oriented, with opportunities to learn, innovate, and make a meaningful impact. Its platform is trusted by more than 15% of the Global 500 across over 80 countries; the company reports that revenue has more than doubled over the past three years and is backed by Insight Partners.

• Strong backend web development experience in a production framework such as Ruby on Rails, Node, Python, or Go, along with shell scripting.
• Deep understanding of databases and SQL, including PostgreSQL.
• Experience managing and deploying backend services, including familiarity with containerization technologies and cloud platforms such as Docker, Terraform, and AWS.
• Hands-on experience building with LLMs in production, including tool use and function calling, MCP, context engineering, and using evaluations and transcript review to identify and fix problems.

Responsibilities

• Build and extend the core Ruby on Rails platform for customer and license management, including customer-facing features and release automation.
• Build and maintain reliable integrations between the platform and business systems such as CRM, support, project management, and BI tools.
• Design and run MCP servers and APIs that provide AI agents governed access to company data and workflows, including tool design, authentication, permission scoping, rate limits, observability, and evaluations.
• Convert requests from Sales, Customer Success, Support, Product, and Finance into tools and automations, and help determine which requests are worth building.
• Own security and compliance for the systems in the role’s scope, including SOC 2 evidence, penetration-test findings, and dependency and vulnerability updates.
• Review code, share systems ownership, and help keep teammates unblocked as part of a small internal tools team.
• Work independently and prioritize whichever work is most valuable at the time.
