About the Role

Internal tooling is a strategic lever at Prelude, essential for scaling operations across engineering, ops, sales, support, and finance. You will own the development of internal tools and AI-powered automation to enhance team speed, confidence, and focus on impactful work. This role involves collaborating with internal stakeholders to resolve friction points and integrating AI tools to define modern company operations.

Responsibilities

Owning the design, development, and maintenance of internal tools used daily across engineering, ops, product, sales, support, and finance
Building agentic AI workflows that automate repetitive internal processes and unlock new capabilities for our teams
Working directly with stakeholders across all teams to identify friction and turn it into functional solutions
Evaluating and integrating the latest AI engineering tools and setting the standard for how Prelude leverages them internally
Contributing to our polyglot codebase and collaborating with the broader engineering team on shared infrastructure, schemas, and APIs
Designing and building internal dashboards on top of our data layer to give every team visibility into what they need to act on
Participating in on-call rotations for the internal platform you build

Requirements

Software engineer with experience shipping in high-paced environments and a track record of finishing what you start
Shipped automated workflows and AI-powered tools in production
Built for internal users before and understand that reliability matters more than polish
Solid backend skills in Go or TypeScript, with the ability to design and build reliable APIs and services
Comfortable working across the stack — React on the frontend when the tool needs a UI, plus the data layer underneath
A preference for simplicity vs complexity, with intuition for what will scale effectively as the company grows
A product-led mindset — you code for outcomes and impact, and you can talk to a non-engineer stakeholder without translating from engineer-speak
Fluent/professional English given our international team
