Software Engineer

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.
