Your Role at Nutrient…

As an Internal Tools Engineer with a strong focus on backend development, you will work on our applications, which power a lot of internal and external needs of the company, from product builds and licensing workflows to revenue analysis and operational management across Engineering, Sales, Product, and Finance.

These tools range from CLI tools written in Bash to a medium-sized Ruby on Rails application that provides our internal as well as customer-facing interface and connects to a variety of 3rd party systems, and serves AI agents via an MCP server. Our primary tech stack: Rails, Postgres, Terraform/AWS.

We are looking for an excellent collaborator who can solve problems independently and hold themselves to their own high standards. You will report directly to the COO and work as part of a small internal tools team, partnering closely with Engineering, Security and our go-to-market teams. If this is you, we want to hear from you.

What You’ll Work On…

• Build and extend our core internal platform, a Ruby on Rails application for customer and license management, including the customer-facing features and release automation built on top of it.
• Build and maintain reliable integrations between that platform and the business systems our teams depend on (CRM, support, project management and BI), so reporting and AI agents work from data people can trust.
• Design and run the MCP servers and APIs that give AI agents governed access to company data and workflows: tool design, authentication and permission scoping, rate limits, observability, and evals that catch regressions.
• Turn requests from Sales, Customer Success, Support, Product and Finance into working tools and automations, and help decide which ones are worth building.
• Own security and compliance for the systems you run: SOC 2 evidence, penetration-test findings, and dependency and vulnerability updates.
• Work as part of a small internal tools team: review each other’s code, share ownership of systems, and keep each other unblocked.
• Be a manager of one, spending your time on whatever is most valuable at the moment.

Requirements

• A background in software engineering with a proven track record of independently driving projects from inception to completion.
• Strong backend web development experience in a production framework (Ruby on Rails, Node, Python, Go or similar), plus shell scripting.
• Deep understanding of databases and SQL (PostgreSQL).
• Experience with managing and deploying backend services, including familiarity with containerization technologies and cloud platforms (Docker, Terraform, AWS).
• Hands-on experience building with LLMs in production: tool use and function calling, MCP, context engineering, and using evals and transcript review to find and fix real problems.

Nice to have:

• Experience designing systems for AI agents as users: clear tool schemas and descriptions, OAuth-based authentication and data scoping, and observability for model and tool calls.
• API or integration work with Salesforce, Zendesk, Linear or similar business systems.
• Experience with SOC 2 or other security compliance work.

Who Thrives Here…

At Nutrient, we’re not just hiring for skills. We’re hiring for mindset. The people who thrive here are:

• Collaborators: You work openly, listen actively, and put team success first.
• Hungry Learners: Rapid learning fuels your progress and career growth.
• Curious Thinkers: You dig into the “why,” valuing understanding over simply being right.
• Self-Starters: You take action without waiting for direction, turning obstacles into opportunities.
• Owners: You take responsibility for outcomes and always look for ways to improve what’s in your control.
• Doers: You focus on results, not activity, and want to know how your work moved the goal.
