Be ready to go over:

• Extensibility – Writing modular, clean code that can easily accommodate new features or changing requirements.
• Testing & Reliability – Writing meaningful unit and integration tests to verify the correctness of your geometric or state-management logic.
• Performance Profiling – Identifying bottlenecks, memory leaks, or unnecessary re-renders in your code.

Example scenarios:

• Refactoring a monolithic piece of geometric logic into testable, isolated utility functions.
• Explaining your choice of design patterns and data structures in your take-home submission.

Web-Based Graphics & Rendering Pipelines

If you are interviewing for a frontend-focused or graphics-heavy role, you will be evaluated on your ability to deliver smooth, responsive visual experiences in the browser.

Be ready to go over:

• Scene Graph Management – Organizing and updating 3D objects efficiently within a rendering engine.
• Shader Programming – Writing custom vertex and fragment shaders to achieve specific visual effects or optimizations.
• Browser Performance Limits – Managing memory usage, avoiding garbage collection spikes, and keeping the frame rate at a stable 60 FPS.

Example scenarios:

• Optimizing a rendering pipeline to handle thousands of parametric building components without dropping frames.
• Implementing a custom selection and highlighting mechanism for 3D objects in a WebGL canvas.

As a Software Engineer at Higharc, your daily work will directly impact the core engine and user-facing applications. You will be expected to take ownership of complex technical areas and deliver high-quality software.

You will design, develop, and maintain high-performance software modules for our web-based CAD and BIM platform. This involves collaborating closely with product managers, architectural designers, and fellow engineers to translate complex architectural rules into elegant, automated code. You will build systems that dynamically generate 3D models, 2D blueprints, and detailed material takeoffs based on user inputs.

Another major focus of this role is performance optimization. You will profile and optimize frontend and backend systems to ensure our web application remains fast and responsive, even when handling massive, highly detailed home designs. You will also participate in rigorous code reviews, contribute to technical architecture discussions, and help mentor other engineers on the team.

We look for engineers who possess a deep love for software craftsmanship and a strong interest in solving complex, multi-dimensional problems. The ideal candidate is a self-starter who thrives in a remote, high-autonomy environment.

• Must-have skills – Strong proficiency in modern software development languages such as TypeScript, JavaScript, C++, or Rust. Solid understanding of data structures, algorithms, and software design patterns. Experience building complex web applications or working with 3D graphics (WebGL, Three.js, or OpenGL).
• Nice-to-have skills – Background in computational geometry, CAD engine development, or BIM software. Experience with React, Node.js, and cloud infrastructure (AWS). Familiarity with architectural design, construction technology, or procedural generation.
• Experience level – We hire across multiple seniority levels, but typically look for candidates with at least 3-5+ years of professional software engineering experience, particularly in roles requiring strong system design and complex problem-solving.

Q: How difficult is the Higharc interview process? A: The process is rated as highly challenging and rigorous. Because we build a web-based CAD engine, we test for deep technical fundamentals, spatial reasoning, and clean coding practices rather than standard, memorized interview questions.

Q: How long does the entire interview process take? A: The typical timeline from the initial recruiter screen to a final decision is approximately 3 to 4 weeks, depending on your availability to complete the take-home challenge.

Q: Is Higharc a fully remote company? A: Yes, Higharc is a remote-first company. We have built a highly collaborative, distributed team across North America, utilizing modern communication tools to stay aligned and connected.

Q: What is the expectation for the take-home challenge? A: We expect production-grade code. This means your submission should be clean, well-structured, thoroughly tested, and accompanied by clear documentation explaining your technical choices and trade-offs.

To stand out during the Higharc hiring process, keep these practical tips in mind as you prepare:

• Focus on the fundamentals: Brush up on your linear algebra, vector math, and basic computational geometry algorithms. Even if you aren't a graphics specialist, having a strong grasp of spatial reasoning is highly valuable across all our engineering teams.
• Treat the code review as a pairing session: During the follow-up code review, our engineers want to see what it is like to work with you. Be open to feedback, explain your thought process clearly, and collaborate on finding the best solutions to any extensions we discuss.

• Showcase your passion for the problem space: We are passionate about transforming the housing and construction industry. Demonstrating a genuine interest in CAD, 3D graphics, architectural design, or automation will set you apart from other candidates.
• Write clean, self-documenting code: Whether in the take-home challenge or during live sessions, prioritize readability. Use clear naming conventions, write concise functions, and structure your code logically.

A Software Engineer role at Higharc offers a rare opportunity to work on a highly sophisticated, deep-tech product that is actively disrupting a massive legacy industry. You will be pushed to grow technically as you solve unique problems in computational geometry, 3D rendering, and high-performance web architecture alongside a world-class team.

To maximize your chances of success, focus your preparation on solidifying your spatial reasoning, practicing clean architectural design, and ensuring your coding execution is flawless. Approach the interview process as a collaborative dialogue, demonstrating your technical depth, receptiveness to feedback, and passion for building elegant software.
