## Job description

About the Company
Dirac is building the creative suite for manufacturing engineering. Manufacturing engineering has been underserved by fractured tooling. The work of defining how a product gets built is spread across process plans, MBOMs, routings, work instructions, spreadsheets, PLM configurations, ERP tables, and internal tools. Each artifact represents only part of the process, forcing engineers to rebuild context whenever a design changes.
BuildOS brings these workflows together in one environment. Manufacturing engineers author, version, review, and distribute the Build—the canonical definition of how a product is produced.
About the Role
Our customers build aircraft, spacecraft, defense systems, ships, energy equipment, and heavy machinery. You'll own features end to end, from the services underneath to the tools manufacturing engineers use every day. The work spans backend, frontend, and 3D, and most of it starts with a real customer problem.
We want engineers who take a problem from vague to shipped, find the root cause before the fix, and use AI tools well while owning the result.
What You'll Work On
Depending on your strengths, you might work on
Turning CAD models into structured, versioned manufacturing data
An authoring experience manufacturing engineers live in all day
Interactive 3D in the browser for assemblies with thousands of parts
AI that drafts work instructions and helps engineers plan a build
Integrations with the enterprise systems manufacturers already run
Secure deployments for aerospace and defense customers
Our Stack
Go, TypeScript and React, Rust and WebAssembly, Python and C++, on AWS and Azure. You don't need experience with all of it.
Requirements
Strong in Go or TypeScript, and willing to work in the other; able to read Rust, Python, or C++ when a bug leads there
Experience building backend services with typed APIs (protobuf/gRPC or similar) on top of a relational database
Experience building non-trivial React frontends with real state management
You debug from evidence: logs, a reproduction, and the root cause before the fix
You check your own work in the running app, not just in passing tests
You use AI coding agents every day and review their output as hard as a colleague's
Clear, concise writing in design notes, PR descriptions, and tickets
You've built something, at work or not, and can explain it in conversation
Nice to Have
CAD, 3D graphics, or computational geometry
Rust, WebAssembly, or GPU programming
Integrations with enterprise systems such as PLM, ERP, or MES
Shipping LLM-based features to production
Cloud infrastructure and Kubernetes
Security or compliance work in regulated industries
A background in manufacturing, aerospace, or defense
How We Work
Own it end to end. You take work from the first customer conversation to proof that it works in the product.
Learn the user. You'll work with the manufacturing engineers who use what you build, and sometimes spend time on their factory floors.
High trust, high agency. If something needs doing, you do it.
AI-native. We build with AI tools every day and hold their output to the same bar as our own.
Fix it once. When we catch a mistake, we fix it and make sure it can't happen again.
Compensation
Base: $120,000 - $200,000 + Equity
Location
Fully in person at our NYC office in the Empire State Building (350 5th Ave). Relocation assistance is available.
